SOLTHERM SDR is cement based, polymer modified and self-coloured dash receiver, requiring only the addition of potable water and 5 minutes mixing time. Normally applied as an excellent background for any dry dash or roughcast finish for new build or refurbishment. SOLTHERM SDR is suitable for use on external wall insulation (EWI) systems (based on EPS and mineral wool) as a part of EWI system. Typical substrates are external wall insulation (EWI) system base coats.
