Description:

RonaScreed 4 Day Overlay Quick Drying Screed additive for site batched screeds is used to quickly reduce the level of retained moisture within the screed allowing floor coverings to be laid over the screed much sooner than with conventional screeds. Rapid strength gain permits early access by following trades.

RonaScreed 4 Day Overlay Quick Drying Screed is supplied in powder form. Each 3kg sachet is sufficient for a 25kg bag of cement. It promotes rapid drying and early laying of floor coverings such as sheet vinyl, tiles and other materials including the range of RonaFloor Epoxy and Polyurethane coatings (refer to Ronacrete Technical Department).
