Customer Questions & Answers

    I have a stable crack in our driveway that is about 10' long. I plan to grind it out w an angle grinder diamond cutter blade, to establish a a uniform width. Then I would install some 1/4" backer rod in the opening and finally fill in above that with a caulk that has a "reasonable modulus of elasticity". To me this means it can accommodate some stretch and yet I want to make it level w the driveway and not have it pull out as car tires go over it. That's the plan in my mind anyway. Would I have to use a primer with Best Bond? Does the depth of the crack to be filled matter? Is three point bonding a concern with Best Bond? Is the plan, as laid out, something you would recommend for installing Best Bond? If the driveway crack job is successful, I would move on to a 20' hairline patio crack. Thank you

    You could use the Abocrete for both of your project. It's a self leveling product.
    2. Is the viscosity of the Best Bond suitable for flowing into hairline cracks? Or do you recommend chasing with a grinder prior to filling? Also, The concrete we use here in the Pacific Northwest is a very light silver gray, can this product be ordered in custom colors?

    BestBond is in a cartridge and mixes as it is applied. You could pump it out into some type of container and mix the pigment into it.
    4. I recently used Abocrete Kit and Aboweld 55-1 to repair a deep crack in a cement step with great results, although next time I won't add so much sand, it didn't flow enough. I have some other cracks in the garage floor, roughly 1/8" wide, several feet long so it should take epoxy without widening. Is BestBond Crack Repair fluid enough to fill and level these cracks or should I mix up some Abocrete with little sand so I get a good easy fill in the cracks? I'd probably use a 150ml syringe for the applicator.

    Answered by the admin If you have the Abocrete, you can go ahead and use that as you describe. The BestBond is fluid enough to fill the crack also.
    5. Can this product be used on stone tile? Can a color additive be used with it?

    Asked by Lorraine Hunter on April 29, 2021 7:56 am
    Answered by the admin Is it a crack in a tile floor? If so, yes, you can use it in that manor. You can't use it in place of grout though. It cannot be tinted as it's packaged in a prefilled caulking type tube.
