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

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.
