FAQ's

1. What is Coo-Var Sealer Coat used for?

Coo-Var Sealer Coat is a clear primer specifically designed to seal porous surfaces—such as brick, stone, and concrete—before applying the GP101 Graffiti Protection System. It improves adhesion and helps prevent the GP101 top coat from penetrating the porous surface, ensuring it remains effective..

2. How does this product improve adhesion for GP101?

By sealing the surface, Coo-Var Sealer Coat reduces absorption and provides a stable base. This ensures the GP101 Graffiti Protection System bonds more effectively, resulting in longer-lasting protection against graffiti.

3. Can I use this sealer on any type of surface?

It’s formulated mainly for porous materials like brick, concrete, and stone. Always ensure your surface is clean and dry before application. For non-porous surfaces, check with our experts for alternative recommendations.

4. How do I apply Coo-Var Sealer Coat?

You can apply the sealer with a brush or roller. Make sure the area is free from dirt, dust, and grease. If your surface is particularly rough or uneven, consider multiple thin coats for optimal coverage.

5. How long does it take to dry?

You can reapply the Sealer Coat in about 2 hours if needed. Wait a full 24 hours after your final coat before applying the GP101 Graffiti Protection System to ensure the best bond.

6. Does the sealer change the appearance of the substrate?

No. Coo-Var Sealer Coat dries to a clear, non-yellowing finish, preserving the natural look of brick, stone, and concrete.

7. What is the coverage rate?

Coverage is roughly 10–15 m² per litre, depending on the porosity of the surface. More porous substrates will absorb more product and may require extra coverage.
