Problem with sealer on slate floor - TilersForums.com

[maudegonne]

Hi there,
I was hoping for some advice. We have experienced a problem with a slate floor that we treated with Qualz 3-in-one sealer.
We have succesfully used it on similar floors in the past. Before applying it with a small roller the floor was cleaned with HG wax and pollish remover. This was washed down twice with clean water and left to dry for several hours. Then 2 coats of the sealer were applied. Problem is that within a week the floor is really badly marked/scraped. It is in a pub and it gets a lot of wear, but this surely should not happen shis quickly?!
Does anyone have an idea why this happened and how we can deal with this?
Any thoughts or help on this are very much appreciated.
Thanks

Not familiar with that sealant, but sound like to much has been applied, as slate isn't very porous, so i would strip it and apply a lithofin or Aqua Mix sealant.

thanks... that could well be the problem as we used a different roller for application....
what would you use to strip it with?

Either lithofin or Aqua mix, both do sealer & coating remover. Use a rotary floor scrubber with a tan pad to remove sealer, and wet vac it up, then rinse floor to neutralise it before applying sealer.
