We use a wide range of preparation materials to level & smooth sub floors. As this is one of the most important parts of glued down flooring materials it has to be correct.

We start be doing a survey of your sub floor and testing for any moisture problems as this is one of the biggest problems with failed floors.  

We use quality Plywood with SP101 which has a full warranty for flooring applications and quality smoothing compounds and damp proof membranes like Uzin, F.ball, Ardex & Tile master.
