Universal Base Coat and Adhesive for embedding mesh and installation of insulation boards.

SOLTHERM UB is a base coat formulated to embed glass fibre mesh in ETICS insulation systems and to bond polystyrene insulation boards to typical mineral surfaces (such as concrete, masonry walls, cement and lime-cement plasters, etc.) as well as to re-insulate walls or install insulation over existing one.

It is also used to level minor irregularities /up to 5 mm/ of mineral substrates and smooth out mineral substrates prior to paint and thincoat render application.
