Customer Reviews for Henry 107 Asphalt Emulsion Sealer and Dampproofer Black Roof Coating 4.75 gal.

Did not use so unable to give review

The product was super easy to apply and seals extremely well on cement and stucco materials.

when not dried out…it works great

good coverage but put it over elastomeric to hide white, and then had 10 gallons on my lawn when it washed off by rain

Always consistent in its quality.

Went on easily. Coverage was more than 158 sq ft advertised... about 225-250 sq ft

The product is easy to apply seals good stop water leak

The website states it's good for wood, but the can says "not recommended for plywood". Also, the roll roofing Cap from GAF specs ASTM D41 primer. Not only does Home Depot not carry any D41, the Henry 107 product isn't really correct for most roofs which are usually plywood. Any help from HD, Henry, or GAF to sort this out would be appreciated.

Bought one pail at HD on Thunderbird, it was bad and two of the other containers we checked were also bad, so I assume the whole lot is bad since the lot numbers are all similar. After returning it, bought another pail at a different HD on Cave Creek & Cactus. The pail bought at the CC&C store had a date code of Sept 2022, I bought it. The contents were proper quality and I installed it.

does the job. no complaints

I was using this on a unflat flat roof. Years ago I applied Henry 287 I believe from memory. The roof was in good shape but has sunk where ponding is an issue. I wanted to reduce ponding by raising some areas with torch down bitumen type wide shingle material. From forums, reviews, and talking to people it looked like the only thing to stand up to ponding was silicone sealant. Ponding is only to last no more than 48 hours. Since I applied the acrylic and was doing torch down I was told the only thing that would make torch down stick was resealing the roof or put down a primer material. Since the acrylic is like a paint and would lift if getting hot I decided to put on two coats of Henry 107. I did this and it seemed to go on okay. Tried torch down bitumen material to raise the low spots on the roof, but is was going to take too many layers to be effective and did not go well. I recoated the torch down with Henry 107 and let it dry. I then applied a competitors silicone sealant. Henry also sells the sealant. How this will hold up is to be seen. I applied it in September of 2022. It has only been a couple weeks for this review. It does look like the roof sealed well with both Henry 107 and the silicone sealant. The 5 gallon bucket that Henry 107 came in had left over sealer and it got pretty hard and would not chip off easily from the bucket. Hopefully this is the same for the roof. It did not seem very fexible on the roof or left over in the bucket after drying. The roof looked like it sealed well with all application of products. Time will tell how this all works. I applied this using a three knot brush. I applied the silicone sealant using a 3/4 inch knap roller.

Good product. Works fine.

Used Henry to seal broken shingles and nails in temporary shingles. Damage to 20 year old roof from Hurricane Ian. Needed to mitigate storm damage until roof can be replaced in a few months. It has rained a few times and Henry did his job perfectly
