The company I subby for has just won a massive contract to tile a supermarket floor. The first phase of the project is 1800m2. Floor will be DPM'd then latexed with Laybond screedmaster 2 ultimate. (Laybond have visited the site and advised this). I just wondered if anyone on here had any experience on this who could advise a reputable company to either do this or that hires the pumps?
