I cant think of any product better than Ardex (first sealer, then the epoxy in "black licorice" (the color will be a point later). WAIT, I can think of something better....CUSTOMER SERVICE!!! I had a problem with my 3rd order...on one phone call Geordi handled it. He and I spoke/exchanced some photos....and in about 34 hours the replacement was at my front door.
NOW here's the interesting aspect. I used "black licorice" epoxy. Where I had to stop I had about 1/3 container left. Rather than letting it harden, (it was going to waste anyway) I got the idea to "fill in divots in my 50 year old blacktop drive way". When I have it sealed I do ask them to "fill in" holes that have developed....but they are NOT going to sit and patch it with a putty knife like I did with the Ardex expoxy. It's been maybe 2 months.....WATERPROOF, adhered like welded steel. Only diff is a slight color variation....and next year when I have a blacktop seal put over....you will NEVER see it. I over-ordered....and I will literally use every bit to seal every crack that I can find, so water does not freeze/crack it further!
