Hey there! As a supplier of WPC Decking Outdoor, I'm stoked to share some tips on how you can install WPC decking outdoor on a brick surface. It's a great way to spruce up your outdoor space, and with the right steps, you can do it like a pro.
Why Choose WPC Decking Outdoor?
First off, let me tell you why WPC Decking Outdoor is a top - notch choice. WPC, or Wood - Plastic Composite, combines the best of both worlds. It has the look and feel of natural wood, but it's way more durable and low - maintenance. You don't have to worry about rotting, warping, or termite damage like you would with real wood.

Preparing the Brick Surface
Before you start installing the WPC decking, you need to prep the brick surface. This is super important to ensure a smooth and long - lasting installation.
Cleaning the Bricks
The first step is to clean the brick surface thoroughly. Use a pressure washer to blast away any dirt, debris, or moss. If you don't have a pressure washer, you can also use a stiff brush and a bucket of soapy water. Scrub the bricks well and then rinse them off. Make sure the surface is completely dry before you move on to the next step.
Inspecting the Bricks
Once the surface is clean, take a good look at the bricks. Check for any cracks, chips, or loose bricks. If you find any issues, you'll need to fix them before installing the decking. You can use a brick repair mortar to fill in small cracks and chips. For loose bricks, carefully remove them, clean the area, and then re - set them using fresh mortar.
Gathering Your Tools and Materials
Now that your brick surface is ready, it's time to gather the tools and materials you'll need for the installation.
Tools
- Tape measure
- Circular saw
- Drill
- Screwdriver
- Level
- Rubber mallet
- Chalk line
Materials
- Traditional Square Hole WPC Decking or WPC Composite Decking (choose the style and quantity you need based on your project)
- Decking screws
- Joist tape
- Plastic shims
- Edge trim
Installing the Joists
The joists are like the backbone of your deck. They provide support for the decking boards.
Layout
Start by measuring and marking the layout of the joists on the brick surface. You want the joists to be evenly spaced, usually around 16 inches apart. Use a chalk line to make straight marks.
Installing Joist Tape
Before you place the joists, apply joist tape to the brick surface where the joists will sit. This will help prevent moisture from seeping between the bricks and the joists.
Securing the Joists
Place the joists on top of the joist tape and align them with the chalk lines. Use a drill to attach the joists to the bricks using masonry screws. Make sure the joists are level using a level. If they're not, use plastic shims to adjust the height until they're perfectly flat.
Installing the Decking Boards
Now comes the fun part – installing the decking boards!
Starting the First Row
Begin by placing the first decking board at one edge of the joists. Make sure it's flush with the edge of the joist. Use a drill to attach the board to the joist using decking screws. Space the screws about 16 inches apart.
Cutting the Boards
As you work your way across the deck, you may need to cut some of the decking boards to fit. Use a circular saw to make the cuts. Measure twice and cut once to ensure accurate measurements.
Spacing the Boards
It's important to leave a small gap between each decking board to allow for expansion and contraction. You can use a small spacer tool or a thin piece of wood to create a consistent gap.
Finishing Touches
Once all the decking boards are installed, it's time to add the finishing touches.
Installing Edge Trim
Edge trim gives your deck a clean and professional look. Cut the edge trim to the appropriate length and attach it to the edges of the deck using decking screws.


Checking for Level and Stability
Walk around your newly installed deck and check for any uneven spots or loose boards. Use a level to make sure the deck surface is still flat. If you find any issues, use a rubber mallet or additional screws to fix them.
Maintenance Tips
One of the great things about WPC decking is that it's low - maintenance. But there are still a few things you can do to keep it looking great.
- Regularly sweep the deck to remove dirt and debris.
- Wash the deck with a mild soap and water solution once or twice a year.
- Inspect the deck for any signs of damage, such as loose screws or cracked boards, and make repairs as needed.
