Concrete Roof Coatings

Concrete roofs will eventually develop cracks that will cause leaks. What’s worse, cracks can occur below the surface and the porosity of concrete slab allows moisture to penetrate and cause roof leaks that are difficult to isolate. A seamless concrete roof coating system provides a watertight solution and allows the concrete to breathe.

Silicone elastomeric roof coatings have better resistance to ponding water than water based coatings. They also stay cleaner longer.

Our EnergyMax® Silicone Elastomeric Coating and EnergyGuard® Silicone Elastomeric Coating are excellent options for concrete roofs.

Concrete Roof Coating Guidelines … In a Nutshell

For detailed instructions, please read our Concrete Roof Restoration Specifications for more information.

1. Concrete must be cured prior to coating. We like to see a full 30 day cure at 75° F.
2. Surface, atmospheric and material temperature must be at least 50°F during application.
3. Remove all grease, dirt, loose paint, oil, tar, glaze, laitance, efflorescence, loose mortar and cement using one of the following methods:
• Concrete Blast Cleaning
• Acid Etching
• Power Tool Cleaning
• Surface Cleaning
4. Concrete must be free of moisture as much as possible. Moisture seldom drops below 15% in concrete. Test for dampness by taping 4 edges of an 18″x18″ black plastic sheet (large trash bags, heavy black rubber mat work very well) for about 16 hours and inspect for moisture, condensation, discoloration on the concrete or under the plastic sheet.
5. Protect exposed, bare concrete from rain or morning dew. If rain is expected, consider applying PrimeLock® Epoxy Primer to retard moisture absorption.
6. Apply base coat of Silicone Elastomeric Coating and allow to dry overnight.
7. Apply finish coat of Silicone Elastomeric Coating and allow to dry overnight.

Sounds easy right?
