MasterProtect H400 : 5 Gallon Enviroseal 40

Surface Preparation
1.Verify substrate has properly cured. Concrete should obtain 80% of design strength, typically achieved within 14–28 days.

2.Clean concrete surfaces of all sand, surface dust and dirt, oil, grease, chemical films and coatings and other contaminants prior to application. Power wash, sandblast, or shotblast as necessary to achieve the desired surface condition.

3. Surface, air, and material temperatures should be 40 to 110° F (4 to 43° C) during application. Do not apply MasterProtect H 400 when temperatures are expected to fall below 40° F (4° C) within 12 hours.

4. A dry surface is suggested for maximum penetration of sealer; however, surfaces to be treated can be slightly damp. Do not apply MasterProtect H400 if standing water is visible on the surface to be treated.

5. Crack control, caulking, patching, and expansion joint sealants can be installed before or after application of the sealer. Allow a minimum of 6–12 hours curing time for caulking and sealant materials (or until they have skinned over) before applying MasterProtect H 400. Following the application, remove excess product that might pond on a concave sealant joint.
