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 for decks, patios, balconies or as a constant walking surface. For larger areas, pour out and spread around with a broom, roller or squeegee

2 Circle around step number design detail

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. (Use Multi-Purpose Primer on wood, concrete and other surfaces where moisture vapor drive is present and EPDM & TPO Primer on EPDM/TPO)

Under investigation

Give me a year to see the result of the item and then I will be able to review the correctly & honestly review about the product as its just a paint but will know after a year the quality and how long it last. Can't review about the result so early.

EPDM Repair

Hi,

If you are looking to repair an EPDM Roof the product works very well but I highly recommend to use a primer with it to ensure an even stronger bond. Great job.

Hello Eric

Yes. Be sure to use our EPDM Primer for EPDM and TPO surfaces as these are very hard to bond to materials.
I don't ever recommend applying to an RV Roof without the appropriate primer.
And be sure to refer to our application guidelines for more very important information on how to achieve the best results possible.
