I came across this product on my many web searches and got a pail to try out. I was quite impressed with the ease of use.
I will be trying it around my neighbor’s pool decking next week and will let you all know how it comes out.
Works well and does as advertised. What I have found is if you have smaller cracks (less than 1/4 inch wide) you need to open them up with a grinder in order to get enough material in it to be effective.
All in all a good product for the DIY crowd.
