Make sure your surface is clean, dry, and free of dirt, silicone, loose paint, rust, oil, grease, coal tar, or other contaminants. Apply using a 3/8 (10mm) roller, brush or paint sprayer. Temperature should be above 10˚C/50˚F and without rain or dew in the forecast when applying.
For extra adhesion, performance, and longevity and to create a moisture vapor barrier, use 1 heavy coat of Multi-Purpose Primer. We recommend applying a test patch before full application.
Apply each coat in an alternate direction to the last coat to ensure even coverage. Avoid contact with solvents and solvent based cleaners, adhesives, and paints. Make sure you do not combine black products with colored products and do not allow products to freeze.
Use Liquid Rubber Caulking for gaps and cracks.
Apply next coat when dry to the touch with nothing wet underneath and is uniform in color. Refer to product data sheet for dry times.
Remove painters’ tape/blocking while coating is still wet. Wrap brushes in plastic to use for next coat.
Ensure weeping tile is working properly channeling water away from your building. Extend rain gutters and slope grade away from your building.
Curing time depends on temperature, humidity and airflow, however typically initial cure is within 24-48 hours as per specific product recommendations.
For best results remove existing paints/coatings and apply directly to the substrate. (Some paints and coatings will not be compatible. Loose/flaky paint may be an indication that the existing paint/coating is not well bonded and therefore your Liquid Rubber solution may fail if applied over it instead of directly to the substrate. Oil based paints, enamels, epoxies, powder coats can be difficult to bond to. Contact your Liquid Rubber technical representative for further direction.) This product is not meant for long term UV exposure or to be used on a constant walking surface.
