SUBSTRATE QUALITY
Substrate must be uniform, dry or slightly damp, free from dust, loose material, surface contamination, existing coatings, oil, grease and other materials, which could reduce adhesion of the coating.
Suitable substrates: concrete, cementitious, brickwork, ceramic tiles, metal, plaster, plasterboard, wood and polystyrene.
SUBSTRATE PREPARATION
General
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.
To confirm adequate surface preparation and Sika® Igolflex®-301 adhesion, carry out a small trial before full application together with adhesion tests as required.
Cementitious substrates
Substrate must be sound with a minimum tensile adhesion strength of 1,5 N/mm2, clean, dry and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
Substrates must be prepared mechanically using suitable substrate preparation equipment to remove cement laitance and achieve an open textured gripping surface profile suitable for the product thickness.
High spots can be removed by grinding.
Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed.
Repairs to the substrate, filling of joints, blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials. Products must be cured before applying Sika® Igolflex®-301.
Brickwork
Mortar joints must be sound and preferably flush pointed. Use localised Sika® reinforcement over joints.
Ceramic tiles
Ensure all tiles are securely fixed. Replace any broken, loose or missing sections. Power wash and use Sika® Biowash as required.
Metal
Metals must be in a sound surface condition. Abrade exposed surfaces to a bright metal finish. Use localised Sika® reinforcement over joints and fixings.
Wood
Wood must be in good structural condition, firmly adhered or mechanically fixed.
Other substrates
Must be in good condition, firmly adhered or mechanically fixed.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened Sika® Igolflex®-301 can be removed with Sika® Colma - Cleaner.
