Coo-Var Acid Etch is a chemical concrete etch designed to remove laitance, salts, and dust from concrete and power-floated floors whilst creating a rough, porous key for paint and screed. Unlike mechanical grinding that creates dust and requires heavy equipment, this chemical abrasion eliminates grinding whilst providing superior surface preparation for optimal paint adhesion.
Developed by Coo-Var with over 115 years of British coating expertise, Acid Etch is the professional solution for preparing smooth concrete, power-floated concrete, and cement screed where mechanical abrasion is impractical or undesirable. The water-based acid solution chemically etches concrete, removing laitance and creating a porous key that floor primers and paints can properly grip.
When concrete and power-floated floors are too smooth for paint adhesion, mechanical grinding is time-consuming, creates dust, and requires heavy equipment. Coo-Var Acid Etch's chemical abrasion eliminates grinding whilst removing laitance, salts, and dust that prevent paint adhesion. The visual bubbling reaction confirms active etching, providing confidence in surface preparation.
The water-based formulation is zero VOC and non-flammable, making it safe for occupied spaces. The simple dilution (1 part etch to 3 parts water) and application by plastic watering can, brush, or mop makes it accessible for DIY users and professionals. Coverage of 7 m² per litre makes it cost-effective for large floor areas.
Suitable for concrete, power-floated concrete, and cement screed in residential, commercial, and industrial environments. After etching and thorough rinsing, prime with floor primers (Coo-Var ProSeal, Coo-Var Dampshield) and coat with floor paints (Coo-Var Floor Paint, Profloor, Profloor Plus, Progrip) for optimal adhesion and durability.
Manufactured in the UK to rigorous standards and trusted by homeowners, contractors, facilities managers, and professional decorators for dust-free chemical concrete preparation.
Key Benefits:
• Chemical Abrasion – Chemically etches concrete to create rough, porous key for paint and screed. Removes laitance, salts, and dust. Eliminates mechanical grinding and dust creation. Visual bubbling confirms active etching.
• No Grinding Required – Saves time and labour by eliminating mechanical grinding. No heavy equipment needed. No dust creation. Ideal where grinding is impractical or undesirable. Dust-free preparation for occupied spaces.
• Removes Laitance & Dust – Removes laitance (weak surface layer), salts, and dust that prevent paint adhesion. Creates clean, porous surface for optimal primer and paint bonding. Ensures long-lasting floor coatings.
• Water-Based Zero VOC – Water-based acid solution is zero VOC and non-flammable. Safe for occupied spaces. Easy application with plastic watering can, brush, or mop. Simple dilution (1 part etch to 3 parts water).
• Superior Paint Adhesion – Creates rough, porous key that floor primers and paints can properly grip. Prevents delamination and coating failure. Ensures maximum adhesion for floor coatings.
• Power-Floated Concrete – Ideal for power-floated concrete which is too smooth and dense for paint adhesion. Chemical etching opens surface without mechanical grinding. Perfect for warehouses and industrial floors.
• Cost-Effective Coverage – Coverage of 7 m² per litre makes it economical for large floor areas. Simple dilution and application. Affordable preparation compared to mechanical grinding equipment rental.
• Coo-Var Heritage – Over 115 years of British coating expertise. Trusted by homeowners, contractors, and facilities managers for dust-free chemical concrete preparation.
