GranoPrime is a solvent-based acrylic primer designed to eliminate uneven substrate absorption on dense or difficult substrates, ensuring optimum adhesion of Granosite coating systems.

Features & Benefits:

• Fast drying.
• Transparent with a white tinge to act as an application marker.
• Eliminates uneven substrate absorption.

Suitable for interior or exterior use. • Ensures optimum performance of the complete coating system by stabilising irregularities in substrate absorption and mechanical strength. • Speeds the application, controls the drying and ensures strong adhesion of topcoats to the substrate. • On concrete, cement render and mortar joints, the use of GranoPrime® minimises the threat of loss of adhesion or other problems that may arise due to presence of residual alkali salts. • As an acrylic, GranoPrime® is not subject to the degradation that can occur with polyvinyl acetates (PVAs) in an alkaline environment.

Recommended for use on:

High Absorption Substrates: Concrete block, Calsil® brick, autoclaved aerated concrete (AAC).

• Medium Absorption Substrates: Off-form concrete under 40mp, cement render, ExoTec®, CFC, fibre cement sheeting, coloured renders, lime washes, GranoRender®, GranoReady Render® (G1.12), GranoPatch Smooth (G1.04), GranoPatch® Spackle (G1.05), GranoFlex® (G1.15). GranoSponge Fine Acrcrylic (G1.21).

• Low Absorption Substrates: Previously painted surfaces, off-form concrete over 40mpa, high density bricks. • GranoPrime® is not suitable for application to steel or timber substrates.

• GranoPrime® may be used as part of the GranoRoof® system for properly cleaned concrete roof tiles.

Instructions for use:

To achieve the indicated performance: 

• Ensure the surface is clean and dry. All substrates must be free of dirt, grease, oil, mould, release agents, bondbreakers or any other contaminants that may interfere with adhesion.

• Fresh cementitious substrates should be left for a minimum of 28 days before coating. There must be less than 15% moisture content in the surface at the time of coating to ensure optimum coating performance. 

• Application should not be carried out if the air temperature or the substrate temperature is below 10°C or above 35°C. The temperature must not fall below 10°C during the drying process.

• Freshly applied material must be protected from frosts and rain for a minimum of forty eight (48) hours
