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.

  • R 50: Backgrounds, including Wood Wool Boards, plasterboards, timber elements, bricks, stones,construction blocks, non waterproofed cement surfaces, gypsum plasters, internal insulation panels, MDF, and plywood.
  • 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).
