Marcotherm primer is a strong, exterior-interior high penetration water soluble primer (bonding agent), which impregnates and strengthens indoor and outdoor mineral surfaces.

Marcotherm primer also improves cohesion, evens the absorption of the substrate and is the suitable binder for decorative coats like Marmorino, Intona, Travertino, Intonachino and various medium or large-grain interior and exterior decorative plasters.

Marcotherm primer has low odour, great opacity, and a ‘sand’ for enhanced grip.
