Concrete Slab - Need Low Moisture for Floor Finish
Concrete Slab - Need Low Moisture for Floor Finish
(OP)
I need to specify a structural slab on metal deck. The slab will have an adhered finish that requires a very low moisture content. What can I do to achieve a low moisture content in a timely manner, without waiting months for a curing process? Will a vented deck help?

I alway feel they are generating extra revenue but without it they won't guarantee the finish.

Very interesting and shows how much variation there is between tests and testing kits.
One comment on EndEng comment regarding the "upcharge" requested by flooring contractors for application of surface applied vapor barriers. It seems to me to be a "pay me now or pay me later" issue, nothing comes free. If you want to the protection of a surface applied vapor barrier to maintain the flooring guarantee, then specify it up front and then it is included in the orginial bid price.
There have been plenty of law suits over this topic and once you suffer the loss from a floor failure due to water vapor pressure, you'll wish you had spent the dollars, it is cheap insurance!
