Densifier or epoxy spall repair first

[j3rm0ff]

I have come to the conclusion that epoxy coating is probably not the best solution for my garage. I'm afraid of moisture and that the concrete is too soft. So I've decided to do a densifier then the ghostshield 8505.

I do need to repair some spalling and I think I'm going to do the legacy industrial hd 110 kit. My question is in which order should I use the products? Repair -> densifier -> sealer or should the densifier be used before the repairs.

It's generally best to do your repairs first. This way you can grind them flush with the rest of the concrete and then apply the densifier and sealer. Keep in mind that the HD110 kit is epoxy based and will not react with a densifier or absorb a sealer.

Agree with Shea, if you don't use a cementious Product like Arden Feather Finish for repairs first the sealer will not absorb in to an epoxy patch.

Sorry to bump this back up. But I just got the products in the mail. Thinking again why wouldn't I apply the densifier first so the the spalled areas will have the same properties as the concrete around it. Won't putting the epoxy patch down first just leave the softer concrete underneath?

And one of the big reasons for using densifier is the white dusting which I understand is just the concrete continually decaying which the densifier should stop or greatly reduce. I am worried that dust will prevent the epoxy patch from bonding well

When you do your patch repairs it requires that you chip or grind out all the loose debris first. Most dusting is within the very most upper layer of the surface. You you will have good concrete for the repair material to adhere to when you prep the repair.
