EcoMortar R Series
The R Series - with the R Series it is possible to go over surfaces that normally require a multitude of coats or treatments. The R Series contains a natural resin that ensures great bond characteristics without impeding breathability. Combined with the absence of shrinkage, this means that R Series mortars are eminently suitable to also be used in low strength solid backgrounds.
Suitable for: Clean dry backgrounds where loose or friable parts have been removed and the plaster is not exposed to excessive humidity or rain.
-
R100: as above plus painted backgrounds (subject to paint being sound and well bonded), smooth concrete/cast concrete (free of demoulding oils), waterproofed surfaces, tiles, metal components (rust treated).
Approximate Coverage: 2m² at 6mm per 25kg bag; 4m² at 3mm per 25kg bag
