    Answer This Question

    A:  Thermaseal will fill hairline cracks. If the crack is larger than a 1/16 to 1/8 than yes you will need to fill cracks.

        A:  Yes, it has to be mixed before using. I used 6 5 gallon buckets of this sealer last year under ideal conditions and several buckets failed to adhere and began washing away on the first rainy day about a month after being applied. The quality control at this company is definitely questionable. Worse, when I left messages on their website to complain about the faulty product, I got no response from the company. Use at your own risk.

          A:  Yes a quick mix is needed.

          by|Aug 12, 2023

            A:  Some buckets do need a little mixing but most don’t. I advise turning the buckets upside down for 24 hours prior to use.

              A:  Yes it must be mixed.

                This product is garbage
                I bought this product because it was recommended for use with cooler temperatures. Prepped as instructed and applied at 70 degree daytime temp and it went into the 50’s at night. Within 2 months it started blistering and now is flaking off in many areas . I wasted over $500 on this crap!
                  36 hours not enough dry time for rain. Damaged
                  Product seemed to be solid, laid down easily until the rain hit 48 hours later. Product stated it needed 36 hours before rain. It damaged roughly half of the material used, which will cost me a ton of time & labor to fix & replace it. A different lower cost material was used on a different section that had no issues with rain and had only half the dry time as this themaseal did. Contacted HD they would not refund or send replacement product, offered a $20 refund. No thanks
                    Driveway sealer
                    Bought 4 buckets, free delivery to my house. Laid buckets on there side. Didn’t need to stir them, very surprised. Spreads very easy, fills in cracks nicely, used crack filler a few days before using this product to fill larger cracks. My temp when applying was 70’s day, 50’s night. Looks great. Does dry to touch in 4 hours, did not put vehicles on it till 2 days just to be safe. Very satisfied with product, will see how long it last.

                      Good coverage - great look. Seal is new so we will see how it survives a NE winter

                      I chose this product because it can be used in colder weather, I think it would have been better in warmer weather, i don’t think it cures well cold.

                      Stirred easily, applied smoothly, dried to expected finish.

                      Worked great. Make sure you wash the pavement and is clear of dust. I had to overcome dust residue after the wash.
