Click to enlargeClean and Prepare the Surface
Clean the surface, and scrape or remove loose debris before starting your project. Be sure surfaces are clean and dry before seam taping or the coating application.


Click to enlargeSeam Taping
The purpose of seam taping is to provide reinforcement over areas prone to splitting, such as seams, cracks or joints, and create a “bridge” that ties the surfaces together so water cannot seep through. Peel & Stick Seam Tape is self-adhesive. Measure out the length of Seam Tape needed and press into place.

Apply Ames'® Super Elasto-Barrier, a waterborne liquid dual-rubber Coating as a primer over the seam tape and the rest of the chimney surface. Super Elasto-Barrier is up to 1000% Elastic. It may be brushed rolled or sprayed.

A topcoat of Ames'® Maximum-Stretch or other Ames coating may be applied to the chimney.

Weather & Drying Guidelines
Ames® Coatings are best applied between 40 to 90 degrees F. on warm dry surfaces. Apply when the streets are dry, the sun is in the sky, and no inclement weather is forecast. Dries in 1-2 hours, depending on thickness of application and weather, and cures in 24 hours. Low temperatures, high humidity, and evening and morning dew will require increased drying/curing time.

Estimated Coverage
Standard product coverage on a smooth surface is 100 sq. ft. per gallon (est. 10ml). More than one coat recommended. More coats equal longer life.
