Hello Everyone, I've been trying to find a flooring solution for my basement. My preferred choice is to refinish the existing slab, but there is an old layer of mastic and carpet adhesive that prevented me from moving forward. Almost every company I've discussed this with has advised me to grind down the slab to remove the adhesives, but I'm concerned about contamination. I know that it can be ground wet and vacuumed out, but it adds a lot to the price, and people have told me that there will be residue and dust. A company recently stated they could do this job without any grinding. They would simply clean the floor, and use a primer that can go over the existing adhesives. They would then use a Polyurea or Polyaspartic overlay that adhere to the primer. The primer is called PerfectPrimer and it's marketed for this use ... So far everyone I've contacted hasn't heard of it, and they're very skeptical; as am I. Has anyone heard or used this stuff?? If so, do you think it would work given the condition of my slab? Thank you very much. Here is the primer site: [url=http://www.ssmincorporated.com/seamsperfect/]Specialty Solutions Manufacturing Inc[/url] I have a call into them, but haven't heard back yet.

I'm in the process of refinishing / staining / sealing my garage and have hit a roadblock. Hoping to get suggestions on a solution. Over an 320 sq. ft. slab, I first coated my floor with a moisture vapor barrier epoxy (Kemiko 1600), followed by three thin layers of concrete micro-topping (Kemko Terra Fresco) and two coats of Kemiko acid stain. In between the epoxy and micro-topping and each subsequent layer of micro-topping, I put down a layer of Kemiko's TFL-1100 bonding agent. I had let the floor sit for about two weeks as time didn't permit putting on the final sealer. Last night, I put down a light mist of water to test the final color and noticed two areas with raised air pockets. It appeared as if there were spots where the micro-topping didn't bond with the vapor barrier epoxy. I used a chisel to pull up the suspect areas but now I'm left with three holes (about 3" in diameter) in the concrete. Does anyone have any experience fixing something like this? I'm resigned to the fact that the patches are going to be visible (hoping to camouflage them a bit with stain) but short of just reapplying the bonding agent and a new layer of micro-topping, is there something else I should try? The epoxy itself is very smooth. I've read online about using a low viscosity epoxy as a base and putting sand on top of that, letting it try to give the base coat some "teeth" to catch on to. Thanks for any help!
