Application Guide

Note: Elasto-Barrier and Blue Max can be used interchangeably for this project type.

Application Process

Step One Surface Preparation

 

Power wash the surface area of the roof to remove most of the loose material. Use caution so you don't damage any interior areas of the building due to roof leakage. You may need to roughen the surface before application. Fill any large cracks and crevices with Blue Max Trowel Grade. Do not use any soaps or detergents.

Step Two Prime the Surface

 

Prime the roof with 1-2 coats AMES Super Primer. AMES Super Primer will dry rapidly and will flow into the cracks and crevices of the concrete rooftop. Let the primer dry completely clear, about 30 minutes to an hour. It will bond to the concrete with remarkable adhesion. Super Primer has an affinity for concrete and glues together and strengthens old concrete surfaces.

Step Three Seam Tape

 

Next, seam tape all remaining cracks larger than ⅛″. AMES Peel & Stick Seam tape comes in 2, 4, and 6 inch widths by 50-foot rolls. This rubber tape contours easily to the surface and will adhere to the primed surface. Once applied, the seam tape will be difficult to remove. For tape to work properly it must be on a smooth surface.

Step Four Apply Elasto-Barrier

 

Prime the surface with AMES Elasto-Barrier using a paint brush or roller at a rate of 2-3 gallons per 100 square feet. This begins to dry in about 2-4 hours but for best results, wait a minimum of 24 hours between coats or until completely dry.

Step Five Top Coat Surface

 

Apply AMES Maximum Stretch roof coating. Two to three gallons per 100 sq. ft. is recommended; however, this could vary based on surface and system used.
