self-levelling compound


Postby Redtool_man » Mon Dec 14, 2009 11:48 am

Hello,

I want to know if I can use self-levelling compound on top of ceramic tiles. I am laying vinyl cushion floor on top so don't want any grooves or bumps that will show through the vinyl. Is there a special compound, do I need to apply something over the tiles first. CAN ANYBODY HELP PLEASE

Lift the ceramics first. Remove as much of the tile addy as you can. Then use SLC to give you a level substrate.

yes there is a product.its a liquid damp proof membrane.
you apply the liquid and throw a special sand on to it.when this sets it creates a mechanical key to which the levelling compound will bond.
this also guarentees that there would be no damp problems.as unlike ceramic tiles the vinyl can wont let the subfloor breathe.this way is the industry standard.but will increase floor height.
hope this helps.

The simple answer is yes. Just ensure to use the correct prima onto your ceramics and that the ceramics are well bonded.
