You'd have to look at what they want to use, look at the potential issues and how it will interact with the finishes you expect to have, etc. Then make a decision. We don't know what finishes you have, what the product is, or any of that. Since you're asking here, I'm going to assume you didn't write the specs. Who did? What's his/her opinion?

The person who wrote the specs is no longer here . Unfortunately everything fell upon me .

Water based, with burlap, is great.

It's a matter of talking to the supplier and finding out the limitations of the product. Were the specs produced by your firm? or by an outside Architect? or someone. If external and the employee is no longer there; for liability reasons, they should be the ones providing the answer.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Well in that case I'd throw it back on the contractor. The spec says don't use it. They want to use it. Force them to prove to you that there won't be any issues. Or just say no and make them follow the specs.

I put it back on the contractor and told them to reach out to the supplier and ask them for potential issues. Thanks a lot

The main problem with water based curing compounds is that they don't work.

Water-based concrete curing compound if formulated from hydrocarbon resins,it takes 4-6 weeks to dissipate from the
surface. Once dried, it is necessary to wait or use suitable petroleum solvent before the surface receive finishing ,tiling..So, Water based acrylic curing compounds are more suitable for indoor application..

I will suggest you to call and ask to the manufacturer of the proposed compound for your specific case..

I'm generally in agreement with Hokie66. Water-based curing compounds may perform in localities where water-based is the only regulatory option but that is because they have good product turnover. Water-based emulsions are storage temperature sensitive and have shorter shelf-lifes than a solvent-based dispersion.

Anything that says Wax Emulsion would not be appropriate. You can water cure or look at a solvent-based Cure & Seal type compound, which usually is compatible with standard flooring adhesives. While cure & seal type compounds are usually compatible with standard flooring adhesives, they won't do as well with leveling compounds.

I think it is still correct to say that when most people refer to ‘water based curing compound’, they mean PVA based products, which just don’t aren’t very effective in curing the concrete.

hokie66 is right! They don't work. Moist cure as dik noted. Won't cause problems with floor coverings and provides better curing.

The only thing better is steam curing (I'm pretty sure, but not positive).+

Good to know. I've never come across a PVA compound because we require AS3799 conformance and thought they'd be uncommon. I found one that claims it falls just short so submitted a technical query for the actual number out of idle interest.

A quick search finds several Dayton products that quote ASTM conformance so presumably not PVA.

Dunking the whole concrete assembly in water once it hardens is even better than moist curing, you get can get crazy cylinder breaks that way.

Back to the burlap...
