Seal slate floor

[MichaelCaditz]

After three years, it is time to re-seal my slate tile floors. I plan on using a water-based acrylic sealant, TileLab® Gloss Sealer & Finish.

I have thoroughly cleaned the floor with water and detergent. Is it necessary to strip off the old water-based sealant?

A sealer I use by Aquamix cant be completly stripped and it says put on a second coat when needed. But is it a wax base and darkened, try Lundmark wax remover if it is. Doesnt sealer on slate make it slippery, I have a slate floor that has never been sealed and is fine, just wash it.

I am now putting two coats of TileLab Gloss Sealer & Finish from Home Depot, also water-based, and it looks beautiful.

Does it make it more slippery when wet?
