How To Build A Composite Deck Over Concrete Patio

Composite decking is a popular choice for homeowners who want the look of wood without the maintenance. It is also a good option for decks that will be built over concrete patios, as it is not as heavy as wood and will not put as much stress on the concrete.

Building a composite deck over a concrete patio is a relatively easy project that can be completed in a weekend. Here are the steps on how to do it:

1. Prepare the Concrete Patio

The first step is to prepare the concrete patio. This involves cleaning the patio thoroughly, removing any dirt or debris, and repairing any cracks or holes.

2. Install the Ledger Board

The ledger board is a piece of treated lumber that is attached to the house and will support the deck. The ledger board should be installed level and at the height you want the deck to be.

3. Install the Joists

The joists are the beams that will run perpendicular to the ledger board and support the decking boards. The joists should be spaced 16 inches on center and should be installed level.

4. Install the Decking Boards

The decking boards are the planks that will make up the surface of the deck. The decking boards should be installed parallel to the ledger board and should be spaced 1/8 inch apart.

5. Finish the Deck

Once the decking boards are installed, you can finish the deck by adding railings, stairs, and any other desired features.

Here are some additional tips for building a composite deck over a concrete patio:

• Use treated lumber for all of the framing materials.
• Make sure the ledger board is properly attached to the house.
• Use galvanized nails or screws to attach the joists and decking boards.
• Space the decking boards 1/8 inch apart to allow for expansion and contraction.
• Finish the deck with a sealant to protect it from the elements.

By following these steps, you can build a beautiful and durable composite deck over your concrete patio.
