Hybrid Solvent Primer

Key Benefits

• Superior bonding and penetration performance
• Deep penetration
• Excellent adhesion
• Seals and strengthens surfaces
• Fast drying
• Reduces dusting
• Easy to apply

Description

A high performance hybrid solvent based primer designed to penetrate, seal and strengthen a wide range of surfaces. It enhances adhesion of subsequent coatings and waterproofing systems by providing an excellent bonding bridge.

• Deep penetration and sealing of porous substrates
• Enhances adhesion on both porous and non-porous surfaces
• Reduces surface dusting and friability
• Improves durability and performance of topcoats
• Suitable for use with most waterproofing systems

Formulated with hybrid resins and special solvents for superior performance and broad substrate compatibility. Ideal for use prior to the application of waterproofing membranes, coatings, paints and sealants.

Recommended Uses

• Roofs, parapets, balconies and terraces
• Concrete, cement screeds and masonry
• Fibre cement, plaster and rendered surfaces
• Metal surfaces including galvanised iron, steel and aluminium
• As a bonding primer before waterproofing and coatings
