Hi Guys
Trichloroethylene is gradually being phased out on H&S grounds, we used to use loads when I was in the lab

Curing is one of those terms that can mean varying things.
In this sense it would normally mean the formation of a strong, irreversible bond. This process takes time concrete is still hardening after 90 years, albeit very slowly !
I would think a solvent based protector will give a better bond but is difficult to use in an occupied house and is really for pretreatment prior to laying.
Any walking on a carpet with protector applied will cause it to wear off before it can be cured.
Cheers
Doug
