4. Detailed Application Instructions

Products can be applied with a paint brush, a push broom, a low nap roller with a long handle or a Commercial Airless Sprayer. For larger commercial jobs. We recommend using a commercial grade airless sprayer. Graco, Bulldog or Titan brands work well. Call for specifications..   

Power wash the surface to remove all dirt and debris and be sure it is completely dry before the coating application. Read all label instructions before beginning. Always run a test patch first in an inconspicuous area, to ensure that proper adhesion and drying occurs and the product works to your satisfaction. Be sure surfaces are clean and dry before the coating application. 

(1) Remove loose dirt, moss, and debris from the roof surface and power wash. Be sure that the surface is clean and dry before starting application of product.

(2) Prime with Ames Super Primer at the rate of 1 gallon per 200 square feet. Dries in about an hour.

(3) Apply two to three coats of Super Elasto-Barrier until roof surface is smooth and sealed.

(Optional) Ames’ Peel & Stick Seam Tape may be needed for any cracks, seams, vents, as well as penetrations. Apply Seam Tape over dried Super Primer.

(3) Finish with one to two coats of Maximum-Stretch or a similar Ames product as needed to complete application. The minimum application of Super Elasto Barrier and Maximum Stretch is 2 gal/100 sq. ft. for each product.
