Can you paint over it

Answers

Yes. You must wait until it skins over. Over night worked well.

can it be heated

Asked by Dean December 27, 2020

Answers

Dean, I would not heat Roofers Choice Plastic Roof Cement unless you are referring to letting it sit at room temperature for a while. It should be ready to use right out of the bucket unless it has been sitting out in the cold weather. If you need a roof cement that will work in below freezing weather I would recommend Henry 208R or Henry 209XR. Both of these mastics can be used in temps as low as zero degrees and underwater or in the rain. Thank you for putting your trust in the Henry Co and the Home Depot.

Can you pour concrete over this product? Building 2nd floor in a few months but need to seal now so drywall is protected

Asked by Jessica August 28, 2020

Answers

When a wall below ground level leaks, you can dig the ground up, clean the wall and put a layer of roof cement on the wall, then a layer of roofing paper or felt followed by another layer of roofing cement. After a day or two, you can slowly put the dirt back in. That said, what you want to do seems much more complicated. Usually, it takes about a year for roofing cement to dry enough for a water based covering, like latex paint or cement. Put the cement on too quickly and it may not stick resulting in gaps. You might call in a contractor to get the info you need. Also, there may be zoning laws involved that may or may not allow what you describe. A construction contractor may be able to give you this info as well.

How long will Roofers Choice 15 Plastic Cement take to dry when used to repair cracks and small repairs? One coat only

Asked by Txredbirds4 July 29, 2020

Answers

I usually give it all day because I'm using it around the perimeter of my house for cracks. I pick a sunny day and allow it to dry all day.

Can I brush it on my roof?

A wide metal baking spatula with a long handle from the dollar store works well. And disposable gloves

Can I apply this right over asfault shingles?

Asked by Paul April 25, 2020
3
Answers

Yes, but only as a short-term stop-gap fix. Long-term, unless your shingles are black, it's going to look terrible (messy). Also, if the shingles move, even slightly, the roof cement coating will crack and will need to be reapplied.

Will this product damage vinyl siding?

Asked by Rm77 April 20, 2020
2
Answers

I would say no if properly applied to your roof. This product is waterproof and does not stain siding unless it is applied directly to or dripped on vinyl siding, which would not make sense.

Will rain affect it when applied 1hr before rain came down.

Asked by Juan March 22, 2020

Answers

The rain may not damage it, but the volitiles will run off and probably stain everything they touch because they take a while to evaporate.

One Year Later It Makes The Matter Much Worse
I put 6 buckets of the substance worth $67.59 onto the roof starting in June 2019. It worked for the first 8 months but after winter here in Shenandoah, Pennsylvania it came apart. It liquified, went through the leak, and made the leak worse in sectors, now it's just as bad as it was originally, except now there's tar all over the roof and over the carpet. I'm just going to lay 4' x 4' wooden panels and 4' x 4' concrete panels to fix this problem up there, possibly more than one layer of that for the edges where a drop may come through. They're heavy and don't get blown off.

It’s a big bucket of really sticky stuff. Spreads nice but has potential to make a mess if you’re not careful. Nice dark black color. Skins over and takes paint well.
