I have an entrance way, lobby, to tile and the client wants 600x600
polished porcelain. There used to be a product you could paint on and it did not affect the finish of the tile, possibly by lithofin
did a sample of the Lithofin one a couple of weeks ago Albert.
did it on an of cut, not as easy to as I thought but probably better on a large area. Problem I had was not getting any bubbles in the liquid, where I did it left marks on the tile.
the process did affect the finish. It etches and gives it a very slightly homed finished and didn't make it as anti slip as I was expecting.
I still have some left and will try in on a larger off cut.
I thought that’s how they worked Albert, by etching the surface?
Lithofins certainly does.
Would it depend on how much you apply as to how much it alters the finish?
I used the Lithofin version on a trade day last year on a 60x60 polished porcelain. I managed to get it to a fairly consistent finish in the end after two applications.
