My Slate and Brick are too Slippery after Applying a Sealer


My Slate and Brick is too Slippery after Applying a Sealer - We pressure washed and used sealer enhancer on our outdoor slate yesterday. Today it is soo slippery we can't walk on it safely. What can we do? Same story on our brick patio but used masonry waterproofer. help!


ANSWER - Most penetrating sealers today claim to make the stone or tile surface more slip resistant.  Years ago a lot of silicone based sealers were used that make the tile surface very slippery.  Slip resistance is based on not only the texture of the surface, but what is on the surface, as well as what type of shoes you are wearing. Of course a wet surface is going to be more slippery than a dry surface.
First I would look at the product information of the sealer you used to make sure it was recommended for how you used it.  Next you need to remove the sealer with an appropriate stripper, which the manufacturer of the sealer should be able to recommend.  If not, there are some high alkaline stripers that can be purchased that remove most types of sealers.  You might have to experiment a bit to find out what works best.

Next you need to re-seal the slate and brick with a sealer that won't make it more slippery.  If the surface of the slate and brick are naturally slippery, which typically they are not, you might have to chemically treat or sand blast to make it more slip resistant before you seal the tile.  You don't want it too textured where it becomes a maintenance problem trying to keep it clean.
