For Step-By-Step Guides Specific to Your Project
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 Sealant & Adhesive 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.
Hey there, I’m still waiting for my order to arrive but I’m looking forward to it
this is liquid rubber, in a one-word I haven’t tested it with time yet, but I hope this will help protect the foundation of the garden house
Product worked great to seal cement around a humid area.
Service was also great, received a leaking container, sent pictures to support and they shipped me a replacement. Thank you!
We used this to seal our foundation from the inside after repairing cracks in it. It’s easy to apply using a masonry brush or roller but a roller is a lot more messy but lighter than a masonry brush loaded up with the material. We did three coats but also learned that you can’t have anything resting against it or it will peel it off when you pull it away. It’s a very soft material so you want to get any framing or covering up as soon as you can. This was 1000x better than any other product I’ve seen for coating and it cleans up relatively easily though you’re going to want to clean outside rather than in your plumbing lines!
I will not use any other product!
