2. To Protect Your Trex Deck

Finishing the edges of your Trex deck with paint or sealant also helps protect it from the elements. Paint and sealant act as a barrier that helps prevent moisture, dirt, and other debris from entering the wood fibers of your deck and causing damage or decay.

How to Finish Trex Deck Edge in 5 Easy Steps

Now that you know why finishing the edges of your Trex deck is important, here’s a quick guide to help you get started.

Step 1: Gather All The Things You Need

The very first step is to gather all the materials and tools you need. You will need a Trex fascia board, edge trim screws, drill bits, a countersink bit, and a screw gun. You have to make sure that the edging you choose matches the fascia board.

Step 2: Measure and Cut

Measure the edges of your deck and cut the Trex fascia board to fit. Make sure to use a square or straight edge so that all cuts are precise. It’s also helpful to pre-drill holes for the screws, as this will make it easier to fasten the boards in place.

Step 3: Attach The Edging

Once all the pieces are cut and pre-drilled, take your screw gun and attach the edging with edge trim screws. Make sure you countersink the screws so that they don’t stick out from the surface. Also, make sure that all screws are securely fastened.

Step 4: Seal the Edging

After you have secured the edging with screws, it’s important to seal the edges. This will help protect the Trex deck from moisture and prevent any warping or damage due to exposure. You can use a waterproof sealant or clear coat to do this.

Step 5: Enjoy Your Trex Deck

Once all the steps are completed, you can enjoy your newly finished Trex deck edge! With proper maintenance and care, this project can last for many years to come. So sit back, relax, and admire your work.

These five steps provide a simple way to finish the edges of your Trex deck in no time. With careful planning and execution, you can achieve a professional-looking result that will last for years to come. Just remember to reseal the edges every few years for maximum protection and longevity.

Frequently Asked Questions

What Precautions Should Be Taken Before Finishing Trex Deck Edge?

Before finishing your Trex deck edge, it’s important to prepare the area. Make sure to clean and dry the surface, remove any dirt or debris, and inspect for any signs of wear or damage. Also be sure that all nails are properly set below the surface of the board for a smooth, finished look. Once the surface is sufficiently prepped, you’re ready to begin applying the finish.

What Type of Finish Should I Use on My Trex Deck Edge?

When finishing your Trex deck edge, it’s important to select a finish that will stand up against outdoor elements and provides UV protection. For most applications, high-quality acrylic latex paint is suitable.

However, if you’re looking for more of a glossy finish or are located in an area with harsh climates, it may be best to select an oil-based solid color stain. Be sure to read the product’s label to determine what type of finish best suits your needs.

How Do I Apply the Finish to My Trex Deck Edge?

Once you’ve selected a finish, it’s time to apply it to your Trex deck edge. For most applications, using a paintbrush or roller will give you the most even coverage. Begin by painting in one direction and overlapping the lines slightly until you have completely covered the area.

Allow each coat to dry before applying another one and be sure to sand lightly between coats for a smooth finish. Once you’re satisfied with the result, it’s time to enjoy your newly finished Trex deck edge!

Can I Use a Pressure Washer to Clean My Trex Deck Edge?

Yes, you can use a pressure washer on your Trex deck edge. However, it’s important to choose a setting that won’t damage the finish. Generally speaking, pressure washers should be used at no more than 1,500 psi for composite decks.

For best results, use only detergents specifically designed for pressure washers and rinse the area after each wash. With proper care and maintenance, your Trex deck edge will look great for years to come!

Are There Any Special Considerations When Finishing My Trex Deck Edge?

When finishing your Trex deck edge, it’s important to be aware of any special considerations. For example, if your Trex deck is in an area that receives partial shade or full sun throughout the day, you may want to select a finish that includes UV protection for the best results.


With the proper materials and knowledge, finishing your Trex deck edge is an easy task. Remember to secure the board end cap and use a little extra time filing down any rough edges for a clean appearance.
