Breathable and clear hydrophobing (water shedding) coating for mineral surfaces such as renders and stone. It is colourless and transparent.
SP Plus provides long-term protection of porous building materials against rainwater, and penetration of moisture.
Does not block pores, non-thermoplastic or film-forming.
SP Plus can only be used on exterior façades on vertical surfaces. Not for horizontal or sloped surfaces like window sills.
It can be used on balanced dry, highly absorbent, porous mineral building substances, free from high water table pressure, standing or rising damp. Hydrophobing is only possible and useful on solid, mineral building fabric, not on external thermal insulation composite systems (ETICS).
