Slate floor tiles require a sealant in order to prevent chipping and staining. Slate is somewhat brittle and sealing the tile helps it perform properly over the long term. Properly sealing the tile is a simple process that just requires some time. Here are the basics of how to seal slate floor tiles. 

Step 1 - Measure the Area

The first thing that you need to do is determine exactly how much sealer you need. Slate sealer comes in a variety of different sizes and therefore, you will want to know how big of a container to buy. Take your tape measure and get the length and width of the room. Multiply the two dimensions together and this will give you the square footage of the room.

Step 2 - Purchase the Sealer

Once you have the measurements of the room, you need to go purchase the sealer. While you can get it at one of the home stores, you are probably better off to go to a tile store. Stores that specialize in tile will have a better idea of what you need. There are many different types of sealer available on the market today. Therefore, selecting the one that is the most appropriate for sealing slate will be the one that you need to find. Get the size and the type that you need.

Step 3 - Sweep the Floor

Before you apply the sealer, you need to make sure that you remove any dirt and dust from the room. Anything that is left on the floor when you seal it will remain there as long as the sealer does. Therefore, you need to sweep the room out and use a dust pan to remove all the dust. 

Step 4 - Mop the Floor

After you have removed the majority of the dust, you should also mop the floor. Wet mopping the floor will allow you to deep clean it and remove anything that is still remaining. While it might seem unnecessary, it is better to be sure that there is nothing remaining instead of sealing it in by mistake and seeing it later. Once you mop, you need to let the floor thoroughly dry before you go forward. 

Step 5 - Apply the Sealer

Once the floor is dry, you need to apply the sealer liberally to the floor. Use a rag and make sure to cover every part of the slate floor evenly. When you are doing this process, you should make sure that the room is well ventilated. You need to open up windows and turn a fan on if you have one. Sealer contains fumes that you do not want to breath in an enclosed area. 

Step 6 - Reapply

After the first coat is applied, you need to let it dry for at least 2 hours. Then you should reapply the sealer again. The first coat usually soaks right down into the tile and the second one will create a protective layer on the top. Then allow that one to thoroughly dry before walking on the floor again.
