Surewall, a factory prepared mixture of Portland cement, glass fibers and other ingredients, is used on masonry, concrete, metal lath and stucco netting. It acts as a crack-resistant finish over concrete, as a decorative coating for building surfaces, to repair building foundations and to bond dry-stack block walls without using mortar. Depending on the type of Surewall mixture used, you can add sand at the job site.
Things You'll Need
- Power mixer
- 1.5 gallons of water
- 75-pound bag of factory-blended Surewall FRP with sand mix
- Hand trowel or plaster gun
Pick a day to apply Surewall, when both the environmental and surface temperatures are above 46 degrees Fahrenheit. Do not apply in direct sunlight in hot weather. Protect the drying period from precipitation.
Mix Surewall with water, according to the ratio specified on the package. Mix only the amount you can use in one hour and use immediately after mixing.
Apply the Surewall mixture to a clean, dry and unpainted surface by hand trowel or plaster gun, to a minimum thickness of 3/8 of an inch and a maximum thickness of 5/8 of an inch. Smooth and level immediately after applying.
Let the application set before applying additional layers. Normally the mixture sets 30 to 45 minutes after mixing.
Fog the set application with water to moist-cure it. This step is reduced or omitted if you are working in damp weather.
Allow the application to dry thoroughly when applying acrylic primers or finishes.
Tips & Warnings
- Surewall has a shelf life of 6 months. Store the container off the ground and away from sun, rain, moisture and freezing temperatures.
- The package will tell you the number of square feet of coverage per bag, though this depends on the thickness of your application.
- Do not add accelerators, pigments, rapid binders, Portland cement or additives of any kind to the mixture.
- The surface, when applying Surewall, cannot contain frost and the substrate must not be frozen.
- Do not add additional water if the mixture sits and becomes firm
