It is best to apply during mornings and evenings without direct sun on a dry day above 10C/50F. The product stays soft, flexible and may have some tackiness, not meant as a constant walking surface. For larger areas, pour out and spread around with a broom, roller or squeegee
Generally you can apply 1-2 coats per day. Apply the next heavy coat when it's dry to touch (typically 6-8 hours), make sure there is no uncured material underneath. Tacky is ok.
Curing time depends on temperature, humidity and airflow. Make sure you do not combine Black products with Colored products, use one or the other.
It’s my second purchase of this tape. Especially good for awning repair!
I used the product to seal my leaking chimney ,easy to apply and covers really well,first test yesterday as we had rain and no leaks in the house
Flat roof on a 25x25 residential garage with mechanical seal which had all failed. Stripped and cleaned the seams. Wiped down with acetone. Applied 4 inch seam tape, one inch primer stripe on each side then 3 coats of sealer with a 6inch roller. Whole process took 4 days allowing each step to dry/cure properly. First rain came last night after a week of dry warm weather. Roof is leak free. Southern Ontario. I have used Liquid Rubber products in the past with similar good results. Follow the directions and recommendations for great performing seal.
excellent product, customer service, delivery.
I haven't used it yet been to wet.but I have a question,can I use as is or do I have to mix it up?
Hello Mr. Tomasiewicz,
The product should come ready to use, although some settling may happen during shipping. If this happens then give the material a mix before using, but take care not to whip air into the mix while stirring.
