eroding concrete

[dereknobleluke]

So we built a new place three years ago. We could have coated the entire floor with some sort of treatment, but we chose to let chemical spills, hot water, and beer run their course and reasses. After all that time, there are two areas, roughly 5 feet wide and a foot across, where the acids and beer (due to their oxidizing powers) have eroded the bicarb of the concrete and the larger stones of the slab are beginning to show through. I have read previous threads regarding U-Crete, Sikafloor PurCem 22N, versaflex, Stonehard, J17 from Dayton Chemicals, VFIroduct number 1007.

so my scenario is two part

1) should I "trowel on" some mud to fill in the large gaps/pits that now exist "in between the stones". And if so quickcrete?

2) then wait a few days and apply one of the aforementioned chemicals....

chip in if you wanna. Either way I will repost what I decided upon and keep updating it as need be!

Cheers

We went with the Sika product, however I believe it can only be applied by licensed dealers. I'm not sure if all the products you listed are the same way, but you may want to contact vendors to find out for sure. Our floor also needed a certain amount of cure time before it could be applied. Again the vendor should be able to give you the details. Lastly, to apply it properly the floor will need to be bead blasted or scarified in some way to allow the urethane concrete to bind to the existing floor. The contractor we used did all of this as part of the job. Hope that helps and good luck.
