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.
-
R50: Backgrounds, including plasterboards, timber elements, bricks, stones,construction blocks, non waterproofed cement surfaces, gypsum plasters, internal insulation panels, MDF, and plywood.
