Asked by: Mike
Yes, this should work. I recommend doing a test area first to make sure you get proper adhesion. Also, make sure to clean and prep the roof before applying. Please follow the roof cleaning and prepping instructions on the label. For more info, check out www.henry.com or contact our product support at 800-486-1278.

Can this be used in over new concrete roof

Asked by: Fla
Yes, if you're trying to glue down some rolled roofing. If you're just trying to seal the concrete roof, then we recommend our Henry 887HS Tropi-Cool 100% Silicone Roof Coating. This will waterproof your roof and lower your energy bills, while giving you a Lifetime Warranty. For more info, check out www.henry.com or contact product support at 800-486-1278.

4.75-Gal. 203 Cold-Applied Roof Adhesive is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Henry 203 I have been involved in the roofing industry since 1993 and have used about every product known and have seen new products come and go. Henry 203 is by far the best cold process product that is non-rubberized that I have personally used from small repairs to full size installations up to 2000 square feet with positive results. It sticks well to mineral surface roll roofing if worked in with a broom or brush even without the use of an asphalt primer. Take your time with it and it softens the roll roofing and can be worked into the ply with great success for repairs. Perfect product for the Do It Yourselfer who needs to take time with it. Pros need patience because most of us want to get in and out because time is money to us. But no other product compares. Great for rock roofs as well. Just remember prep is everything so follow the specs on the label or go to the Henry web page for instructions. Ask a Home Depot Pro for help and tips with this and you will have exceptional results! This product gets 5 stars +
