Cromapol is a fibre-reinforced liquid acrylic resin dispersed in solvent, designed to prevent water ingress. Its high fibre content allows the coating to bridge small gaps and provide instant waterproofing with just one coat. Cromapol is available in Mid Grey, White, and Black, and also in a fibre-free formula in Opaque, White, and Mid Grey. This versatile product offers excellent adhesion, instant protection, and outstanding solar reflectivity (in White and Grey).
Key Points:
- Instant Waterproofing: Single coat application bridges small gaps and provides seamless protection.
- Versatility: Available in fibre-reinforced (Mid Grey, White, Black) and fibre-free (Opaque, White, Mid Grey) formulas.
- Durability: Fully flexible with excellent adhesion and reinforced membrane (fibre-reinforced formula only).
- Additional Benefits: No wash-off, economical, and excellent solar reflectivity in White and Grey.
Coverage: Cromapol provides an average coverage of 1–2 kg per m².
Shelf Life: The product has a shelf life of 12 months when stored in undamaged, tightly sealed containers.
Storage Conditions: Store Cromapol indoors at temperatures between 5°C and 20°C, away from sources of ignition, naked flames, and out of reach of children.

Application Instructions
Before applying Cromapol, ensure the surface is clean, dust-free, and free of debris. Remove all moss, lichen, and plant growth using AlphaChem Fungicidal Wash, paying special attention to corners and gutters. The area to be repaired should be free from standing water. Repair any cracks, splits, small holes, or flashings, and for gaps or expansion joints larger than 3mm, reinforce with Glass-Fibre scrim and Cromapol prior to full coating. While Cromapol can be applied to damp surfaces, for best results, application to a dry surface is recommended.
Cromapol can be applied easily using a brush, roller, or squeegee. Application temperature should be between 5°C and 25°C. Drying time varies up to one week, depending on temperature and coating thickness. The coating may remain soft during this period, but this does not affect its waterproofing performance. For detailed application instructions tailored to specific surfaces or uses, consult Cromar Building Products.
Please note: These instructions are for guidance only and do not guarantee product performance. While every effort has been made to ensure reliability, Cromar cannot accept liability for any loss, injury, or damage resulting from use.
