Red Devil0971 Blacktop and Roof Polyurethane Sealant, 10.1 Oz, Black

Very good at sealing cracks in the driveway. I wait a month to allow the polyurethane to cure and then have the drive way sealed with tar. This approach helps to minimize the chance of water getting under the driveway and heaving it. Have a couple of disposable narrow putty knives handy because this sealer is very sticky and will ruin the putty knife so don't waste a good one. Using the putty knife and spreading the sealer along the crack makes for a professional appearance.

It works, is a little thick and takes a wider opening than I desired.

I have ordered this blacktop filler every year and it has been great. Ordered 2 more tubes recently and both are bad. Had them replaced and both were bad. They are solid and the caulking gun can't push anything out. Do not buy!

The crack filler applied easillty and cured quickly while matching the pavement.

works great on small cracks in drivewayit takes a long time to use up one tube if using on small cracks, works very well, pretty thick, takes a couple of days till no longer tacky

The first Tube of this Sealer I bought worked Great; and I filled a good size crack across my driveway. It flowed well and setup as stated. The second (separate) order for the same Sealer was bad. The entire tube was a solid mass. A received a refund; but since I needed to seal another driveway crack, I reorder it again. And again, it came in an almost solid mass.The Seller, Hardware City, could not explain or even guess what had happened, THEN, Amazon to the rescue. Amazon said it would resupply me a another tube with no charge. My guess is that this Red Devil product has a shelf life and that these were simply old tubes. I am hoping the laws of chance smile on me and I get a fresh tube...again.

Fabulous stuff! Goes on easy, clean up is a snap. Could not be happier!

I wish I could submit a review without a rating, as I was unable to actually use the product. It had solidified in storage before being sent to me and it was almost impossible to squeeze any out of the tube. I have it sitting in a box awaiting pickup for return.

J'utilise ce produit afin de scellé les trous dans mon asphalte apres le retrait des clous de fixation de mon abris hivernal.J'utilise ce produit depuis des années, Ce produit est excellent, simple a appliquer et demeure flexible année après année.

Product is a little thick. Even after poking several holes inside the tube. Some effort is required to pump this product out using a caulking gun.

It’s tar, easy to install, looking forward to how long it will last

Easy to use, and gets the job done. Great sealant.

This sealant goes on very smoothly when applied, very flexible and it should last for a long time. The product comes in the color black ...other colors should be offered.
