Watco Asphalt Crack Filler - Flexible rubberised bitumen formula, for repairing and filling cracks in old asphalt and tarmac

Absolutely spot on. Did the job well. Had originally used cold roll tarmacadam which was a SOB to get in the cracks and simply opened up again wide in the heat of this summer. This stuff was a breeze to use in comparison.

This product is not fit for purpose. I followed the instructions to the letter on a warm, dry day. It says it cures in 2-4 hours or 6-10 hours depending on the size of crack filled. 96 hours later it is still curing and after a rain shower (long after the manufacturers stated curing times) has made a real mess of the surrounding asphalt that will take a long time to weather and blend in. Avoid at all costs

I use this to fill small patches of missing asphalt. I mix it with sand or small chippings for durability. It seems to do the job. It is water soluble when not set so don't apply when rain expected, but useful to clean hands and utensils.

This product is nothing like the seller described. I followed the application instructions exactly, yet a week later, only the surface is slightly dry; it still dents with just a light touch. I tried contacting the seller, but they haven't responded at all. It’s absolutely terrible.

I mixed it well and cleaned up the cracks with an angle grinder as per instructions but the filler has skinned over but not set 3 DAYS later.
