Why we love it
Solvent-free, easy cleanup.
Applies to damp surfaces.
Long-lasting waterproof protection.
Main highlights
TWO SIZES AVAILABLE – Choose from a 5-litre or 25-litre jerry can.
SOLVENT-FREE FORMULA – It's water-based for easy clean up, contains no solvents, and is non-flammable.
HIGHLY WATER REPELLANT – Creates a waterproof coating on a range of materials whilst still allowing the surface to breathe and any moisture vapour to evaporate, including brick, concrete, render, stone and pebble dashing, although is unsuitable for rubber, plastic or timber.
HIGH PERFORMANCE – Provides protection that lasts through deep penetration into the material and a durable matt finish that's transparent once dry.
EASY TO APPLY – Apply this milky-white liquid to clean, dry or damp surfaces using a roller, brush or low-pressure garden sprayer.
CAN BE APPLIED TO DAMP SURFACES – The water-based formula soaks into the material for long-lasting protection, making damp (not wet or submerged) surfaces acceptable.
VERSATILE APPLICATION: Suitable for factories, warehouses, kitchens, garages, workshops, and production areas; bonds to concrete, sand/cement screeds, blockwork, and plastered walls
LOW VISCOSITY FORMULA: Excellent penetration into substrate pores; provides superior adhesion and subtle sheen on interior floors
EFFICIENT COVERAGE: 5 litre container covers up to 25 m²; requires two coats for optimal results; each coat dries within 1-2 hours
EASY TO USE: Apply with brush, roller, or spray; no primer required; creates smooth satin finish on various indoor surfaces
DUST-PROOF PROTECTION: Creates long-lasting dustproof surfaces with 100% acrylic formulation; ideal for concrete and stone floors
