The linoleum on your kitchen floor is worn, dated and ugly. You have been threatening to replace it for months, but the time has come; you have to do something now. Granite is one of the most attractive and durable flooring options available. The tiles are inexpensive and you can easily install your new granite floor in a weekend.

Things You'll Need

• Granite Floor Tiles
• Plastic Spacers
• Wet Saw
• Backerboard
• Backerboard Screws
• Thinset
• Notched Trowel
• Rubber Mallet
• Grout Float
• Grout Sponge
• Penetrating Grout Sealer
• Paper Towel

Instructions

1. Make sure the sub-floor is clean and dry. Remove peeling paint and residual sealant by sanding or scraping the floor; patch any imperfections with a waterproof compound.

2. Know your plan. Start in a 90-degree corner and lay your floor tiles. Use plastic spacers to keep the granite tiles properly aligned. Trim to fit, as necessary, with a wet saw. Take your time; careful planning at this stage will ensure a smooth professional appearing install.

3. Mix thinset according to package directions; use the trowel to spread an even layer of thinset on the sub-floor. Place the backerboard and screw it down. This creates a uniform surface and protects your granite from damage.

4. Hold the trowel at a 45-degree angle to form consistent ridges and spread thinset. Cover only an area that you can complete in 10 to 15 minutes. Use a slight twisting motion to press the granite tile into the mortar and tap it down with a rubber mallet to force out any air pockets and ensure complete contact. Repeat the process until all tiles are laid; use plastic spacers to guarantee correct placement. Allow the mortar to cure for 24 hours. Stay off the tiles.

5. Mix grout in small batches that can be used within 20 minutes. It should be the consistency of toothpaste; let it stand for 5 minutes before using. Work the grout into the tile joints with a grout float; clean off any excess with the edge of the float and a damp sponge.

6. Allow the grout to cure for 72 hours before applying a penetrating grout sealant. Use paper towel to wipe any excess sealant off the tile immediately, as it will mar the granite’s surface. Step back and admire your new granite floor.
