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 comes with a ‘sand’ for enhanced grip.

Colour: pure white, with good opacity


Impera Italia’s Advice™

Marcotherm can be applied on wood, metal, glass, plastic and virtually any interior and exterior surface; it’s arguably the strongest bonding agent for Italian plasters on the market. Please be aware that for smooth finishes either a Marmorino base coat or a thicker first coat of the chosen fine finish is required, due the Marcotherm’s grain.


Tool: roller or brush
Number of coats: 1 or 2, wet on wet
Diluting: 20-50% with water, depending on the support surfaces absorption (generally 30%)
Indicative spreading rate: 8 to 10 metre square per litre
