How to Install Slate Floor Tiles:

1. Prepare the surface

Prepare the subfloor for a clean and dry, flat and even surface. If plywood is used as a subfloor, then a backer board needs to be installed/attached to the subfloor as an underlayment.

2.Preview tiles layout

As slate tiles have a lot of color variation, they have to be blended randomly so that light and dark colors won’t wind up together.

3.Spread thin-set on floor and set permanently.

Spread thin-set on floor evenly with a notched trowel starting from the corner of the room and then place the tiles o thin-set and press firmly to form a secure bond. Place the tile spacers 1/8th inch or as per the slate supplier instructions.

4. Remove any excess moisture/thin-set between tiles.

5. Allow the slate and thin-set to dry for 24-36 hours depending on weather location.

6.Apply clear sealer on slate tiles before grouting (or after grouting as per supplier’s instructions).

7. Mix the grout and apply grout between joints with a grout float.

8.Wipeout entire surface with a sponge to remove any excess grout.

9. Allow grout to dry or harden for 24-48 hours depending on weather and supplier’s instructions.

10. Apply a clear sealer to seal the slate tiles as per directions.
