Primer K

Water-based acrylic micro-emulsion especially suited to sealing and consolidating absorbent, weak or powdery mineral surfaces. It is alkali resistant and compatible with the air and hydraulic binders commonly used in construction (air lime, hydraulic lime, cement, gypsum).

Primer K is ideal as a fixing and consolidating primer on existing lime or cement plasters, lime finishes and screeds with weak surface strength and cohesion. Thanks to its small average particle size and special composition, Primer K penetrates deep into the substrate, binding loose particles and preventing dusting both at the surface and in depth. It also reduces and evens out the water absorption of the treated surfaces, improving the bond of subsequent paint or mineral skim coat/finish layers.

It can also be used as a bonding primer on smooth or poorly absorbent substrates such as concrete, or added to air or hydraulic binder mortars to improve their elasticity and bond strength.

Summary of features:

• Water-based acrylic sealer and consolidant;
• Ideal for consolidating plasters and absorbent cement or gypsum mineral surfaces, or as a sealer for plasterboard, gypsum fiber and fiber cement;
• Can be used as a bonding primer on concrete or smooth, poorly absorbent substrates, or added to air or hydraulic binder mortars to improve their bond strength and elasticity;
• Highly penetrating micro-emulsion;
• Contains no organic solvents;
• Does not form a vapor barrier;
• Excellent UV resistance;
• Very low VOC content.
