Depends on the roughness and absorbency of the substrate.

Substrate must be sound, free from oil, grease, loose and friable particles.

Concrete tensile strength ≥ 1.5 N/mm².

Cementitious substrates must be prepared mechanically using suitable abrasive blast cleaning or planing / scarifying equipment to remove cement laitance and achieve an open textured gripping surface.

Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed and filled / repaired with compatible Sika® products.

Steel substrates must be prepared mechanically using suitable abrasive blast cleaning to remove all corrosion products and achieve a bright metal finish.

All dust, loose and friable material must be completely removed from all surfaces before application of the product and associated system products, preferably by vacuum extraction equipment.

Clean all tools and application equipment with Sika® Reinigungsmittel-5 immediately after use. Hardened material can only be removed mechanically.
