The coverage rate is noted as 1.5-2.0 gallons/100-square feet...is this for 100-square feet of rolled roofing (i.e., one can of this stuff per 2-2.5 rolls of roofing), or is this raw coverage (i.e., one can will cover 9-10 rolls of roofing).
Asked by: Greg
Each bucket will get you approx. 237 sq ft to 318 sq ft of coverage depending on the surface. So, with that said, you're first statement would be correct that it should cover between 2-3 rolls of mineral cap sheet. For more info, check out www.henry.com or contact our product support at 800-486-1278. Thanks for putting your trust in the Henry Company and Home Depot.

Will Henry 203 bond to Henry 209? On a low slope roof I have my base sheets down and done but noticed that along the edges, where the sheets meet the lip of the metal flashing, there is cracking. My next step was to lay down mineral surfaced SBS cap sheet using the 203. To solve the cracking along the edges I was thinking about laying down some 209 over the cracking areas before laying down the 203 to adhere the cap sheet. The big question is: will the 203 bond to the 209?
Asked by: steve
Steve-Yes, 203 will bond to 209. Please let us know if you have any additional questions and thank you for putting your trust in the Henry Company and The Home Depot.

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 +
