Measure the garage floor to determine how much material will be needed. You will need the following materials:
- Wood sleepers (or 2x4’s instead of the sleepers) and rigid foam insulation with the same thickness
- Plywood sheets (3/4” thick)
- Polyurethane glue and mineral spirits glue remover to clean up any spilled glue
- Floor tiles to finish the floor
You will need the following tools:
- Two saw horses
- Circular saw
- Utility knife
- Drywall saw
- Glue trowel
- Measuring tape
Attach the sleepers to the floor, twelve inches apart. Glue the sleepers to the floor with heavy duty glue. Once the sleepers are securely in place you cut the insulation. The insulation should fit snuggly between the sleepers. Cut the insulation with a utility knife or a drywall saw.
The plywood goes down next starting along the side of one wall. Measure and mark the sleepers and nail each piece of plywood in place. End pieces need to be cut to size.
Use a tape measure and pencil to mark each end of the plywood, then use the chalk string to make your cutting line the length of the plywood. Then lay the wood across the two saw horses and use the circular saw to cut the plywood to size.
While using the circular saw be sure to use safety measures and wear safety goggles to protect your eyes.
After the plywood is all nailed down thoroughly sweep the floor. The floor needs to be completely smooth before laying the tiles; remove any glue droppings and make sure all the nails are flush.
You always begin in the middle of the room working outwards when laying tile. Make a chalk line to follow so the tiles will be straight in all directions. There are two types of tiles: those with a sticky back, and those you will need to glue in place. For the ones that require gluing, apply a thin layer of glue with your trowel and place four tiles together with the tips of each tile touching in the middle. Gently rub out any air or extra glue with a small hand towel or rag.
Repeat the process for each tile making sure to line them up evenly with the chalk line and adjoining tiles. Be sure and wipe off any excess glue from set in place each tile using the mineral remover. You will need to let the floor set for two full days before walking on it.
