Customer Questions & Answers

Is this a liquid or more of a paste?

Asked by: Pinseeker
It's more of a paste. You will need to apply with a trowel

Can this be used to seal holes in the roof of a metal container?

Asked by: Hiwaydogg
Yes but use the mesh with it on small holes. On larger holes I would cut a piece of galvanized flashing to cover the hole before applying

Can I use Henry wet patch to seal leak on outside basement poured wall seam between poured wall and brick seam?

Is this product rubberized to expand and contract in winter climate. It is a roof product so wondering if I can use it to coat outside of my exposed basement wall . I was looking at Blue Max liquid rubber and wonder if this works the same way. Thank you for your help as I must get this wall sealed.Elaine
Asked by: Elaine
I would say this would not be a good solution for below ground outside use, as typical ground freeze/thaw cycles would cause this to crack over time with the ground rubbing against the cement wall. If you have a "hole" in the cement, you should patch the cement using a plasticized cement filler, then use a cinder block/cement water block paint which penetrates the pores and waterproofs.

0.90 Gal. 208R Rubber Wet Patch Roof Cement is rated 4.5 out of 5 by 222.
Rated 5 out of 5 by from Henry 10 year Rubber Wet Patch really seals under Water. This product is real easy to apply & adheres to everything. I had a leak on my flat roof that was covered with Tar & Gravel. After sweeping aside the gravel at the suspected area, I saw plenty of minor tar cracks & used a 3" putty knife to spread the Henry Patch onto the surface. A few days later it rained heavily again, & the leak coming thru a bedroom ceiling slowed down from initially dripping in 1.5 gallon of water, to 0.5 gal. So on that day it was raining I went up to the roof & started spreading more Henry tar around a larger section of that area that now had puddles of rainwater. This 2nd. application totally sealed this hard to locate leak point.

I have used this stuff numerous times...messy, but works on almost any surface. Wear rubber glove, the latex type, no matter what you do, you will end up with some of this stuff on you....I use plastic 2 to 3 inch wide spreaders. Fills in large gaps, spread smooth..I used this time to fill in big gap by electric weather head...and worked great as always.....but black, black, best used in areas not visible from the street or yard.

Rated 5 out of 5 by from Difficult to get out of the can. but, pliable, sticky and so far, no leaks! This can be difficult to get out of the can, but, spreads well, adheres to prior parches and shingles, and seals, usually, without running or spreading in the summer sun. However, it will crack and sag if its applied thickly, or across a 1/2"+ crevice of even with the mesh tape, and will require annual re-treatment. **** It will not mix with silicone -- don't use any silicone on your roof or gutters ever!; doesn't seal, won't adhere over time, is messy, can't be painted, etc. Then, it will clean nicely with WD-40 from hands, tools and clothes!

I used some fiberglass tape as reinforcement and backing. It works really well on small rust holes in the gutters. It works pretty good on the gutter seams too as long as you don't have to apply a thick coat. Thin coats dry fairly quickly, depending on the weather and don't droop. If you have to apply a thick coat, the tar tends to droop. I suggest using several thin coats if needed, letting each coat dry completely before applying the next coat.

Rated 5 out of 5 by from Well Worth The Money Worked Like A Charm I paid a licensed roofer $400 to fix a leak on an extension from my house. Needless to say I still had the leak. I tried this product for the first time a couple years ago, and it worked perfectly. The leak stopped. When I noticed a problem starting in another area, I immediately picked up another can. I used a putty knife to apply. When I finished coating the area it started to drizzle. I was a little worriedl that it may not work seeing that it hadn't had time to cure so I thought. Well...... I was wrong! It worked like a charm again. I am a female over 50 and I will never pay anyone else again I will do it myself. Thank you , thank you thank you for making this product so reliable that even someone like me could use it and get excellent results.
