Professional-Grade Solvent Cleaner for Preparing Surfaces Prior to Waterproofing or Adhesive Application Biokil Crown Premium Substrate Cleaner is a high-performance solvent-based cleaning agent designed to remove grease, oil, adhesive residues, dust, and other contaminants from substrates prior to the application of waterproofing membranes, coatings, tanking systems, or adhesives. It ensures maximum surface compatibility and adhesion, making it an essential pre-treatment in structural waterproofing, floor preparation, and damp-proofing applications. Key Features & Benefits Powerful Solvent Action: Effectively dissolves grease, oil, grime, and organic residues from concrete, metal, masonry, and synthetic surfaces. Adhesion Optimiser: Improves the bond strength of waterproofing slurries, epoxy systems, tapes, and sealants. Fast Evaporation: Rapid drying time minimises delays before subsequent product application. Multi-Surface Compatible: Suitable for use on concrete, render, tiles, membranes, and most construction surfaces. Essential for Detailing: Ideal for use on laps, junctions, corners, and plug seals where high bond integrity is required. Product Details Type: Solvent-based substrate degreaser and cleaner Appearance: Clear, volatile liquid Packaging: 1L and 5L tins Coverage: Approx. 10–15 m² per litre depending on substrate condition Application: Cloth, brush, roller, or low-pressure spray Evaporation Time: Typically dries within minutes at ambient temperature SKU: BKPSCLEAN1 / BKPSCLEAN5 Application Instructions Preparation: Ensure the area is well-ventilated. Remove loose dirt or debris before applying the cleaner. Apply Cleaner: Use a lint-free cloth or brush to apply to the substrate.
