Sopro RAM 3® (454) Renovation and Levelling Mortar

Universal, grey, sag-resistant, rapid-set, fibre-reinforced, cementitious render and surface filler for smoothing, patching and rendering of wall and floor surfaces. For application to mineral substrates, e.g. concrete and masonry. Excellent workability and mouldability. Ideal for renovation and refurbishment. Ready for tiling after only 2 hours. Suitable as plinth render, for the formation of angle fillets and to create falls, for use in damp and wet spaces, and on balconies, patios and steps/stairways. The mortar’s rapid strength development allows early removal of uneven patches in filler coat using plasterer’s lattice plane. Low-chromate to Regulation (EC) No 1907/2006, Annex XVII.

Sopro RAM 3 ® is suitable for rendering, patching, smoothing and levelling of wall, floor and ceiling surfaces in concrete (to DIN 1045) and in pumice, clay, calcium-silicate and composite masonry. For producing level, plumb and true substrates for subsequent installation of ceramic, natural and cast stone cover-ings.  Particularly suitable for renovation and refurbishment works, offering excellent mouldability. Also suitable for the formation of angle fillets, as plinth render and as levelling coat to provide falls where structural substrate has no gradient, in damp and wet spaces or on balconies and patios. Once set, Sopro RAM 3 454 is water-vapour-permeable and resistant to water and freeze-thaw cycles.
