- Nonvitreous: highest absorption
- Semi-vitreous: less absorbent
- Vitreous: standard absorption level
- Impervious: resistant to absorption
- Coefficient of Friction: measures how slippery the material is
- PEI rating (Porcelain Enamel Institute): ability to resist wear and tear
How to Install Granite Floor Tiles
1. Prepare the surface
Prepare the subfloor for a clean and dry, flat and even surface.
2.Preview tiles in place and apply mortar
You can either start the tile from the center or from to corner of any door as per layout design. Once the layout is decided, mix the adhesive/mortar/thin-set (as per manufactures directions) specially made for granite flooring. Apply a thin layer of 6-8mm mortar using a trowel and spread it evenly covering small areas at a time or as per manufactures instructions.
3. Lay the tiles in place and set permanently.
Place the granite tile on top of mortar a press firmly. Place the tile spacers (1/8th inch or 1/16th inch as per manufactures indications. Cut the tiles to place over the edges and check the level of tiles.
4. Remove any excess adhesive/moisture between tiles
5.Set the tiles for at least 24hrs before laying grout.
6. Mix and spread grout over tile as per manufactures directions.
7. Clean the entire surface with sponge to remove excess grout from top of tiles.
