1. What is Coo-Var Acid Etch & Floor Cleaner used for?

Coo-Var Acid Etch & Floor Cleaner is a water-based acid solution designed to prepare bare concrete floors for painting. It removes salts, laitance, and light contamination, chemically etching the surface to improve paint adhesion—especially in high-moisture areas like swimming pools.

2. How do I apply the acid etch solution?

Use a plastic watering can to distribute the solution evenly on the floor. Then, work it into the surface using a stiff brush. Allow it to react as per the instructions, and thoroughly rinse once the etching process is complete.

3. Why choose acid etching over grinding or sanding?

Acid etching avoids the dust and mess associated with mechanical methods. It’s a quicker, cleaner approach that leaves a paint-ready surface without generating clouds of concrete dust.

4. Can it be used on damp floors or pool areas?

Yes. Coo-Var Acid Etch & Floor Cleaner is specifically formulated for high-moisture environments, such as swimming pool floors and damp concrete surfaces. This makes it especially useful where traditional grinding might be impractical.

5. How does it improve paint adhesion?

By removing laitance (the weak top layer of cement) and opening the pores of the concrete, the etched surface allows paint to bond more effectively. This results in a stronger, longer-lasting finish.

6. What coverage can I expect?

Coverage is approximately 7 m² per litre, although it can vary depending on the substrate’s porosity and condition. Very rough or contaminated surfaces may require more solution or repeated applications.

7. Are there any safety precautions?

Yes. Always wear protective gear (goggles, gloves, etc.) and ensure good ventilation during application. Avoid contact with skin or eyes, and follow all label instructions for safe handling and disposal.
