Intro

0:00

deck clips continue to be one of the

0:02

most popular methods of fastening

0:04

brazilian hardwoods um i’ve talked a

0:06

little bit about camo in my about

0:07

fastening uh methods

0:09

video and i encourage everybody to watch

0:11

that but this video i’m gonna go into

0:13

detail about deck clips specifically

0:15

brazilian wood depot deck clips so stay

0:18

tuned we’re going to get into it

0:21

[Music]

Deck Clips

0:36

okay like i said deck clips continue to

0:39

be one of the most popular methods of

0:41

fastening

0:42

ipe decking and brazilian hardwood

0:44

decking i’ve talked a little bit about

0:46

camo i’ll make a separate video going in

0:48

more detail about camo in this video i

0:49

want to talk to you about our deck clips

0:51

how they’re different um the pro plug

0:53

system which almost always not always

0:55

but almost always goes with the deck

0:57

clips and then at the very end of this

0:59

video stay tuned or skip forward i don’t

1:01

mind

1:02

and watch me put these few boards

1:04

together

1:06

i kind of show you the process and the

1:08

little quirks about using our deck clips

1:10

and deck clips in general so the first

1:13

thing is what makes our deck clips

1:15

different than other deck clips um

1:18

well our deck clips as you can see here

1:20

are t-shaped i’m going to put an image

1:22

on one of these two sides here so that

1:24

you can see it as i’m i’m talking about

1:26

it with you

1:27

they’re t-shaped uh deck clips

1:30

what you see here is the regular deck

1:32

clip on the bottom and then about 25 of

1:35

the extra wide deck clips i’ll tell you

1:36

what those are for and then a drill bit

1:39

actually a drive bit on the top some

1:41

deck clips have a screw going in at an

1:44

angle they want you to pre-drill the

1:46

bottom of the deck board here

1:48

right below right into the groove so the

1:50

screw goes into the deck clip at an

1:52

angle and then into the joist that’s not

1:54

how ours work ours don’t require

1:56

pre-drilling

1:58

my goodness

2:00

um you just go straight into the clip

2:02

into the joist so there’s no

2:03

pre-drilling involved uh that’s one

2:06

difference another difference is um some

2:08

all other deck clips on the market don’t

2:10

have very wide wingspans and what i mean

2:12

by the wingspan is the grab into the

2:15

kerf of the board the kerf or the groove

2:17

i’m going to refer to it as kerf a lot

2:19

in this video because that’s what we

2:20

call it

2:21

ours have

2:22

i think it’s just about a half inch of

2:25

grab on the board

2:26

and anything

2:28

less than that is really not sufficient

2:30

and i wouldn’t advise it i know there’s

2:32

a lot of different kind of clips on the

2:33

market and i don’t know about all of

2:36

them i just know that some of them have

2:37

a very short wingspan and that’s not

2:40

good the other clips um i won’t mention

2:42

them by name but you may know uh that go

2:44

into a for the screws go into them at a

2:46

45 degree angle

2:48

the problem is when you get the boards

2:49

together you lose access to that screw

2:52

head uh which in my opinion is not ideal

2:54

also you’re pre-drilling which

2:57

you know adds to uh the the overall

3:00

labor

3:01

um when you use our deck clips i’ll talk

3:03

about it when i go through it but you

3:05

must use uh construction adhesive on the

3:08

joists um it keeps the boards in place

3:11

what happens is if you don’t use

3:12

construction adhesive on the joists the

3:14

the boards expand and contract ever so

3:16

slightly from season to season so what

3:18

can happen is

3:20

some boards may go one direction other

3:22

boards may go another direction but you

3:23

can build up lateral pressure if boards

3:25

want to go inch in the same direction

3:27

and eventually something’s got to give

3:29

so then you have buckling i’ve never

3:32

ever heard of boards buckling when using

3:35

construction adhesive the brand name

3:38

that we throw around here is liquid

3:39

nails any all-weather construction

3:41

adhesive is appropriate this is not why

3:43

this is here so really tight bond is not

3:46

the right answer um liquid nails is fine

3:48

i’ll talk about tight bond when i get to

3:50

the pro plug system um

3:53

some people say well i’m using joist

3:55

tape so can i use the joist tape with

3:58

the instruction adhesive no don’t do

4:00

that that’s not ideal um it’s not going

4:02

to give as good a hold to the

4:04

deck tape as it does the wood so the

4:07

glue actually serves as a joist

4:09

protectant and if you ask some old-timer

4:11

contractors they’ll tell you glue works

4:13

very well to protect the tops of the

4:15

joists where it meets the board that’s

4:17

typically where you run into problems

4:20

okay so we talked about why we like our

4:23

deck clips over other deck clips and i

4:25

stand by that i really do

4:27

for the first and last boards i use the

4:30

pro plug system when i’m quoting my

4:32

customers you can also use a stainless

4:34

steel trim head screw but you have to go

4:36

into the face of the board for instance

4:37

if this is a deck this structure here

4:40

and i’m the house you can’t get a you

4:42

don’t can’t get a clip here and you

4:43

can’t cut a clip in half for over here

4:45

so you go through the face of the board

4:47

with some plugs that’s where the pro

4:48

plug system comes into play we like the

ProPlug System

4:50

pro plug system because it comes with

4:52

this pro plug tool it’s actually sold

4:54

separately but we sell them together

4:56

so

4:57

the pro plug tool pre-drills your screw

4:59

hole and i use this on this

5:01

demonstration piece so i have mine open

5:06

i’m waiting for the banging to stop

5:10

it bores the whole

5:11

it bores the hole with this uh blade

5:13

here and then it pre-drills your screw

5:15

not only that but it has the stopper

5:16

it’s a there’s a rubber gasket on here

5:18

so it has this really nice stopper that

5:20

will stop at the exact right depth so

5:22

you grab you get your plug you uh dab

5:26

some glue around the edges and then you

5:27

can use a board to

5:29

tap it flush um you could sand it a

5:31

little bit i guess that’s that that’s

5:33

typically uh a good idea but i don’t

5:35

think you have to sand it every time

5:36

i’ve gotten them flush flush enough with

5:38

just using a scrap piece of board that

5:40

you don’t need to sand it at all so

5:43

that’s all i have to say i think about

5:46

these clips good wingspan on them um oh

5:49

the double wad clips you’re going to see

5:50

me use them here in a second the reason

5:52

we these are brand new we’re the only

5:54

ones that have a double wide clip and

5:55

the reason we have them are for butt

5:58

joints on butt joints before you have

6:00

you could use two clips or try to grab

6:02

the corner with one let me show you what

6:04

i mean right here

6:08

right where this line is

6:10

um so right where that line is on either

6:12

side of the board here and down here i

6:15

used a

6:17

double wide and you can use the double

6:18

wides on any place on the board it

6:20

doesn’t have to just be on butt joints

6:22

but you only get 25 of them in a pack so

6:24

use them where the butt joints are if

6:26

you don’t have any butt joints then use

6:27

them wherever you want

6:29

i think it’s a really cool feature and

6:30

hopefully i still have this image up so

6:32

you can see exactly what i’m talking

6:33

about they’re double the width of the

6:34

regular clips okay that’s all let me

6:37

show you how i put this thing together

6:39

and then i’ll come back one more time to

6:40

sign off before we get started i want to

6:42

let you know that i’m not a deck builder

6:43

or a deck installer i have virtually no

6:45

experience in that area and also i’m not

6:46

particularly handy the joists that i’m

6:48

using in this demonstration are not

6:49

perfectly in line which makes things

6:50

even more challenging again this is for

6:52

demonstration purposes only thank you

6:55

okay so remember when you’re getting

6:57

started we’re going to use you want to

6:58

use glue on the joists

7:00

you really need to use glue on the

7:02

joists because when they expand and

7:03

contract boards can walk and build up

7:05

pressure in certain areas i’m not going

7:07

to use liquid nails

7:09

on these joists just for

7:11

demonstration purposes

7:13

but you must use glue on the joists when

7:16

you’re using these

7:18

when you’re using these clips

7:19

so on the first edge on the first board

7:22

the glue is really not as important

7:24

although you might as well

7:25

it’s not as important because we’re

7:26

actually going to be putting a screw

7:27

through this first board so first we’re

7:29

gonna go in with the pro plug tool

7:32

and uh the pro plug

7:35

kit here so i’ll set it right here i’m

7:37

gonna do this the plugs later

7:40

we’ll get this we have the screws and

7:41

the drive

7:43

bit here

7:51

so again we love this system we sell the

7:53

system a lot with both our clips and the

7:56

camo system again it bores out the right

7:58

size hole so you can save your save your

8:00

forstner bit um and it goes the right

8:03

depth which i think is the most

8:04

important thing the main thing is go in

8:06

and out a couple times make sure you’ve

8:08

boarded out completely giving yourself

8:10

enough clearance

8:12

all right we’ll come back

8:14

and fill the

8:16

plug the holes later at the end

8:18

everything looks nice here

8:20

all right

8:21

now we talked about the wider clip

8:24

so i’m going to do the next board my

8:27

butt joint board

8:28

and what you’ll notice here is that i’ve

8:30

already sanded these edges it’s a really

8:32

good practice to stay in the edges of

8:34

the butt joints

8:35

because it makes it look so much nicer

8:37

than just having two square ends

8:38

together for instance like this

8:41

that

8:42

these boards are already a little tooty

8:43

chewed up but square edges just they

8:45

don’t they just don’t look as good you

8:46

could take an eighth inch roundover bit

8:48

but i did three passes on the top one

8:50

two three

8:51

um

8:53

three or four 60 or 80 grit i think mine

8:56

was uh

8:57

80 grit but you can use 60 grit too it’s

8:59

just as effective

9:06

so what i’m showing you here is the wide

9:08

clip versus the smaller clip and i’m

9:10

using the wider clip on the butt joint

9:13

one thing that made this demonstration a

9:15

little harder is because the center

9:17

joist was about 3 16 lower than the two

9:19

side joists which is not typical um

9:24

i was just you know throwing this

9:25

together for this demonstration which

9:27

which is fine um you know subfloor

9:30

adhesive

9:31

um

9:32

construction adhesive like liquid nails

9:34

like we’ve been talking about using on

9:35

the joists is really good for filling up

9:38

the kind of gaps that might be between

9:40

the heights the differences of height

9:42

between the joists it fills that up

9:44

nicely so

9:46

you know there’s there wouldn’t really

9:47

be any problem either way but the glue

9:49

does

9:51

you know even those kind of things out

9:54

but in this case it kind of just made it

9:55

harder for me

10:15

now look at me i left a little gap you

10:17

do not need to leave this gap here you

10:19

can have them straight flushed together

10:21

like this i like it because i think it

10:23

looks nice it’s got a similar edge to

10:24

these on the side i just think it looks

10:26

nice you don’t have to do it that way

10:28

you don’t need that gap

10:32

the main thing is when putting these

10:34

clips down is when you’re screwing them

10:35

in before you get the next board in

10:37

don’t over tighten you over tighten them

10:38

you won’t be able to slide it on no big

10:40

deal just back out the screw and then

10:42

slide the board and then tighten the

10:43

screw the drill drive bits are really

10:45

skinny and they’re made that way so they

10:47

fit between these boards without nicking

10:50

them

10:54

but you notice how i started here got

10:57

the plugs flush brought in the next set

10:59

of clips brought those down don’t over

11:01

tighten come back and tighten these

11:03

get these close screws

11:05

started

11:07

not too tight don’t over tighten come

11:08

back and tighten these next board in

11:11

now tighten i can tighten the screws

11:12

because this last edge even though it’s

11:14

lifting a little bit it’s going to be

11:16

pulled down with the pro plug system so

11:17

back to the pro plug just for a second

11:23

and a little pro tip about the pro plug

11:25

system the pro plug kits come with the

11:28

plugs two and a half inch stainless

11:29

steel screws and a glue nozzle

11:32

uh the proplug tool is sold separately

11:34

but um the ipe

11:36

uh ipe pro plugs are also sold

11:38

individually and you could use your own

11:40

cheaper steel screws if you have them

11:44

time to go back with the the pro plugs

11:46

themselves

11:55

and what you’ll see is that these plugs

11:57

fit perfectly in

12:00

to these holes

12:01

i usually use a little block

12:03

piece of scrap block

12:06

now first you have to dab in

12:08

the glue it comes with this glue nozzle

12:10

um i like to use tight bond

12:12

i typically will get a screw

12:15

put the type on in a container get the

12:16

screw in there and then wipe it around

12:17

the holes

12:18

just like that

12:20

get it in there

12:21

not going to do that right now because

12:23

it’s kind of messy

12:31

tap it with a hammer go over it quickly

12:33

with a sander later

12:39

again glue around the sides

12:44

i’ll finish this up

12:45

but but there you have it that’s the

12:47

general process

12:49

i’m going to go dry down and finish

12:50

making the rest of this video

12:53

and i’ll sign out after i dry the sweat

12:56

off my face

Outro

12:58

all right folks thanks for watching my

12:59

little tutorial here about our deck

13:01

clips

13:02

i still really like them i also like the

13:05

camo system uh but i think every not

13:08

everybody a majority of customers um

13:10

still don’t know about the camo so they

13:12

always ask about the clips and

13:14

you know sometimes we don’t have time to

13:16

explain the camera system but i

13:17

generally tell people to watch the about

13:19

fastening methods video i’ll put a link

13:21

to that

13:22

here right now but here is my project

13:25

not quite finished because i didn’t have

13:27

the time i have the plugs in here i need

13:29

to tap them down a little further

13:31

i didn’t include the plugs in here uh

13:33

just because i wanted to get this video

13:35

finished and i think everybody gets the

13:37

idea remember glue on the joists round

13:39

over the edges for the butt joints use

13:41

the wide clips on those butt joint areas

13:44

and use the wide if you have extra wide

13:45

clips just use them wherever you want

13:46

because there’s no harm in using them

13:48

even if there’s not a butt joint thanks

13:50

for watching i’ll be back soon

13:53

Text-Based BWD Clip Certified – Installation Guide for Grooved Boards Instructions

Text-Based BWD Clip Certified – Installation Guide for Grooved Boards Instructions

This text-based reference provides an accessibility-friendly version of the full BWD Clip Certified – Installation Guide for Grooved Boards resource.


## Introduction to Grooved Boards & Hidden Fastening

Brazilian hardwoods such as Ipe, Cumaru, Tigerwood, Garapa, and others are dense, stable materials capable of accepting side grooves for hidden fasteners. These grooves allow boards to be installed using T-shaped clips that secure the deck from the edges rather than the top surface, creating a clean, fastener-free appearance.

Grooves may be applied to a variety of profiles, including 1×6, 5/4×6, 1×4, 5/4×4, and 1×8 boards.
BWD’s clip system and installation recommendations apply to all standard grooved hardwood deck boards.

A demonstration of BWD Deck Clips is provided in the accompanying video within the resource.


## Overview of the BWD Clip Fastening Method

### Why Use Clips?

  • Allows hardwood boards to maintain a clean, fastener-free surface.

  • Securely holds boards while still letting them expand and contract naturally.

  • Creates consistent lateral spacing when installed correctly.

  • Provides strong mechanical connection along the full length of the deck.

### Construction Adhesive Requirement

The guide strongly recommends pairing clips with exterior-rated construction adhesive applied directly to joists. Benefits include:

  • Keeping boards aligned along their centerline

  • Preventing deck creaking

  • Acting as a leveling compound over uneven joists

  • Adding a protective layer over joists, improving long-term performance

  • In some cases, protecting joists better than joist tape

For a broader comparison of different fastening methods, see the Deck Fasteners overview.


## Step-by-Step Clip Installation Instructions

### Step 1 — Apply Construction Adhesive

Run a continuous bead of exterior construction adhesive along the tops of all joists where boards will be installed. Apply enough adhesive to install the first two boards before it begins curing.

### Step 2 — Install Clips Along the First Board

  • Place a clip at every joist along the full length of the board.

  • Drive the screw until the screw head sits level with the top of the clip.

  • Do not overtighten — overtightening tilts the clip downward, making it difficult to insert the next board.

### Step 3 — Insert the Second Board

Slip the grooved edge of the second board into the clips installed along the first board. Ensure that the board seats firmly and consistently across all joists.

### Step 4 — Install Clips on the Second Board

Install clips along the outside edge of the second board just as in Step 2.
Once clips are in position:

  • Return to the clips between Board #1 and Board #2

  • Tighten them fully to secure the boards together

  • Continue this pattern for the entire deck: install clips, insert next board, tighten prior clips


## Video Demonstration – BWD Deck Clips Installation

A full video demonstration accompanies this guide: [BWD Deck Clips – Video](https://www.bwdepot.com/BWD_DeckClips/). In the video, Sam walks through how to install grooved Brazilian hardwood decking using BWD’s T-shaped clips, construction adhesive, and the Pro Plug System for perimeter and starter boards.

### What the BWD Deck Clips Video Covers

– Why deck clips remain one of the most popular fastening methods for Ipe and Brazilian hardwood decking.
– How BWD’s clips differ from many other brands:
– T-shaped profile that drives **straight down into the joist** without pre-drilling.
– Generous “wingspan” with roughly **½” of grab** into the kerf/groove for a secure hold.
– Screw heads remain accessible from above, even after boards are installed, unlike some 45° screw systems.

– The importance of **construction adhesive on the joists** when using clips:
– Prevents boards from “walking” in opposite directions as they expand and contract seasonally.
– Reduces the risk of lateral pressure and board buckling.
– Acts as a **joist protector**, sealing the interface where joist and board meet.

– Why **joist tape should not be used under the adhesive** for this system:
– Adhesive bonds best directly to wood.
– Glue can do more to protect the joist top than tape in this specific clip approach.

### Pro Plug System Walkthrough

The video also demonstrates using the **Pro Plug System** alongside BWD Deck Clips:

1. Use the Pro Plug tool to bore a shallow counterbore and pre-drill the screw hole in a single step.
2. Drive a 2½” stainless steel screw to the correct depth; the built-in stop ring sets the hole consistently.
3. Apply wood glue (such as Tightbond) around the sides of the hole.
4. Insert a matching hardwood plug and tap it flush using a scrap board and hammer.
5. Lightly sand if needed to blend the plug into the deck surface.

This method is recommended for:
– **First and last rows** where clips cannot be used against walls or borders.
– **Perimeter boards, picture frames, stair treads, risers, fascia, and rail caps** where face fastening is required but a clean, plug-concealed look is desired.

### Butt Joints, Wide Clips, and Eased Ends

In the demonstration, Sam highlights several best practices that apply directly to this guide:

– Use **extra-wide double clips** at butt joints to give both board ends a strong, shared anchor.
– Sand or round over butt-joint ends (three quick passes with 60–80 grit or a ⅛” roundover bit) to soften the edge and improve the finished look.
– Maintain a small, intentional gap at butt joints if desired to match lateral spacing and reduce the appearance of imperfections.
– Avoid overtightening clips before the next board is installed; lightly snug them, slide the board in, then tighten once boards are seated.

Together, the written instructions and the BWD Deck Clips video give a complete picture of how the clip system works, why adhesive is required, and how to combine clips with the Pro Plug System for a professional, long-lasting hardwood deck installation.

## BWD Exclusive Clip Sizes

BWD Deck Clip packages include two clip sizes:

  • Standard Clip – 0.75″ (approx. 75% of the package)

  • Double-Wide Clip – 1.5″ (approx. 25% of the package)

The double-wide clips are designed specifically for butt joints, offering greater holding strength, improved alignment, and better long-term stability where two board ends meet.


## Hidden Fastening with Plugs and Screws

Some areas cannot accept clips — such as perimeter boards, picture framing, stair treads, risers, fascia, rail caps, and other transition pieces. These areas use:

  • Stainless steel screws

  • Hardwood species-matched plugs

### Pro Plug System (Starborn Industries)

This popular system includes:

  1. Drill pilot hole

  2. Create counterbore with the matching tool

  3. Drive the stainless steel screw

  4. Insert the wooden plug flush with the surface

Plugs create a long-lasting, discrete, aesthetically clean fastening solution.


## Hardwood Handling & Universal Pro Tips

### Wax & Oil Guidelines

  • End Wax is required on every exterior hardwood job. Seal ends after cutting to prevent end checking.

  • Oil only after installation, not before. Installation handling can disturb the finish.

  • Oiling is optional; boards will naturally fade from sunlight even without oil, without affecting structural performance.

  • Do not oil the underside of boards—no performance benefit.

Detailed maintenance procedures appear later in the guide.


## Storage and Climatization of Hardwoods

### Storage Requirements

  • Store boards dry, off the ground, out of sunlight.

  • When using tarps, use clean, undamaged tarps. Dirty or torn tarps can cause staining.

  • Do not wrap the tarp tightly around the bundle; promote airflow.

### Promoting Proper Acclimation

  • Increase airflow between layers using spacers between each row.

  • Ensure spacers will not stain or damage boards.

  • Allow air movement throughout the stored stack.


## Tooling and Handling Guidance

  • Dense hardwoods require quality tools, but standard carbide-tipped blades work well.

  • The number of teeth on a blade generally has minor performance differences, though fine-tooth blades reduce chip-out.

  • Dust sensitivity varies per person; set up cutting stations downwind.

  • Rinse sawdust off skin periodically to prevent irritation.

  • Use proper dust collection as needed.


## Stainless Steel Hardware Requirement

All exposed surface hardware must be stainless steel.

Using non-stainless steel fasteners leads to:

  • Oxidation stains

  • Black rings around fasteners

  • Ongoing staining until the problem is corrected

### Situations That May Cause Steel Contamination

  • CAMO system throwing steel shavings

  • Runoff from newly installed asphalt shingles

  • Cast iron or non-coated metal furniture

  • Gutter leaks dripping onto deck boards

Stains can be removed with mild acids (muriatic, citralic, or oxalic), but the issue will persist unless hardware is replaced or covered.


## Easing the Ends of Boards

Hardwood decking arrives with radius edges, but cut ends are square.

### Easing Methods

  • Orbital sander with 60-grit

    • Three passes at a 45° angle

  • Router with 1/8″ round-over bit

    • Matches factory radius perfectly

### Benefits

  • Cleaner, more professional appearance

  • Reduces visibility of imperfections at joints

  • Especially recommended where boards meet at posts or transitions


## Board Spacing Guidelines

### Lateral Spacing

  • Recommended spacing: 1/8″

  • Acceptable range: 3/32″ – 3/16″

  • CAMO system requires 3/16″

### Butt Joint Spacing

Hardwoods exhibit minimal expansion along their length, but spacing improves appearance:

  • Recommended: 1/16″ gap

This helps butt joints mimic lateral spacing for a consistent look.


## Avoiding Mitered Joints and Corners

Mitered joints (cut at 45°) are discouraged due to movement under weather and seasonal changes. They tend to:

  • Open

  • Shift

  • Misalign

  • Highlight expansion/contraction more visibly

### Preferred Alternative

Use a lap joint or other non-mitered transition to turn corners cleanly.


## 1×12 Fascia Installation Requirements

Directly fastening a 1×12 fascia to the banding/joist will cause cupping.

### Solutions

  1. Bottom-Grooving Method

    • Cut grooves to relieve internal stress (grooves approx. half material thickness)

  2. Furring Strip Method

    • Use 1×2 furring strips (¾” × 1.5″)

    • Vertical orientation

    • 16″–24″ spacing

    • Create ½”–¾” air gap

Compatible furring materials: pine, treated pine, PVC, composite, vinyl, etc.


## Airflow Requirements for Hardwoods

Airflow is essential to maintain consistent moisture content across all four sides of a board.

### Positive Airflow Features

  • Sloped grade below deck

  • Unobstructed cross-ventilation

  • Consistent spacing between boards

### Consequence of Poor Airflow

When air-moisture-content (AMC) differs above and below boards:

  • Sun dries the top of boards → contraction

  • Moisture accumulates beneath → expansion

  • Result: cupping

Even heavily cupped boards may flatten once airflow is corrected.


## Blocking: Good vs. Bad Practices

### Bad Blocking

Examples include:

  • Excessive joists or blocking beneath decking

  • Continuous surface contact with blocking

  • Blocking aligned parallel with decking, causing full-length cupping

  • Boards cup over sections with too much contact (typically 6″–8″)

### Good Blocking Solutions

  • Ladder blocking to reduce surface contact

  • Lower triple beam by ½” and add marine-grade plywood strips (1.5″–2″) to prevent direct contact and promote airflow

  • Reduces risk of cupping

  • Protects beams from premature rot


## Drainage Systems & Cupping Risk

Drainage systems are popular but often restrict airflow.

### Membrane Systems

  • Cost-effective and easy to install

  • Most restrictive for airflow

  • Highest likelihood of cupping

### Rigid or Pan Systems

  • Hang beneath joists

  • Improve airflow

  • Can integrate duct fans for circulation

  • Still often require supplemental mitigation (bottom grooves, furring)


## When Airflow Optimization Is Not Possible

### Bottom Grooves

When airflow is restricted (drainage systems, excessive blocking, contact with beams):

  • Use bottom-grooved boards

  • Grooves relieve internal stress

  • Allow top and bottom to expand/contract more evenly

  • Reduce or prevent cupping

Recommended on:

  • Deck tiles alternatives

  • Installations over drainage pans

  • Boards touching solid surfaces
