CAN COMPOSITE DECKING 

BE  CUT?

Yes! You can cut most composite decking just like wood — no special tools required.   Please check the manufacture’s recommendations before starting your project.

START WITH

THE SAW

Do you need a special saw blade to cut composite decking?

Circular saws and miter saws are the best tools for cutting composite decking. Keep in mind that a fine blade will slow down the cutting process.

Additonal Cutting Tools Needed:

- Tape measure - A pencil or blue chalk reel. (Red chalk is not advised as it can stain the boards.) - Eye and ear protection -Speed Square

TO SAND OR

NOT TO SAND 

No Sanding Needed:

Unlike traditional wood decking boards, composite decking doesn't need to be sanded. Sanding composite decking could even cause damage and void the warranty.

STEP BY STEP

CUTTING GUIDE 

Step 1: Prep

Store your deck boards before installing: - Cover to ensure boards stay clean and free of debris, as well as protected from uneven weathering. - Store in flat bundles for ease of handling.

Step 2: Edge

Use the speed square and pencil (or chalk reel) to mark and cut 1/8” off one end of your board to ensure a clean, square edge.  You do not need to seal the edge. See step 4 for cutting instructions.

Step 3: Measure

Measure the board length needed based on your deck design. Use the speed square and pencil (or chalk reel) to transfer your measurement.

Step 4: Cut

Line up the saw blade on the side of your mark away from the piece you plan to keep. Ensure hands are away from the blade — use any safety equipment provided by the saw manufacturer. Pull the blade carefully through the composite material with a smooth gesture.

Step 5: Install

Install the boards with hidden fasteners according to the fastener instructions. Repeat to fill the deck space. Now it’s time to let your client (or yourself) enjoy a deck that inspires life. These directions assume the installed boards overhang the frame edge and need one long finished cut. A do-it-yourselfer will likely need to hire a professional to achieve this. We advise cutting each board to length and installing it.
