Slate Tile Sealer
Choosing the best slate tile sealer when sealing slate tile is important for a few reasons.
First of all you want to make sure the sealer is a penetrating sealer and not a topical coating.
Topical coatings will give a glossy finish to the slate tile, which some people like, but are setting themselves
up for some heavy maintanence costs when it comes time to restoring the finish (not recommended).
Also, putting a topical coating will make the slate tile more slippery and very hazardous when wet.
One more thing about topical coatings, all stone and masonry surface need to breath.
Having a topical coating will not allow the stone surface to breath and any moisture that needs to escape
may crack the tile when forcing itself through the surface.
As you can see, I don't recommend any topical coating on any natural stone.
The two types of sealers that we recommended for slate tile are no finish
penetrating sealer, and color enhancing sealer.
We recommend using the color enhancing sealer because most of the slate tile we see in peoples homes
has a natural chalky appearance, especially after cleaning.
Using a color enhancing sealer to seal slate tile will darken the slate, hide the chalkiness of the natural
look of the tile and bring out the colors.

have settled on using MB-21 Color Enhancing Sealer.
The results are amazing and the ease of use are the reasons why we choose MB-21 Color Enhancing Sealer.
Approximate coverage of 1 pint is 100-200 square feet, depending on the porosity of the slate tile.
