HOW MUCH CURING CHEMICAL?
HOW MUCH CURING CHEMICAL?
(OP)
For preventing concrete from loosing its moist due to wind and hot weather, curing chemicals can be used especialy for concrete pavements. The chemical material is usualy sprayed on top of the pavement and it works forming a very thin sealent, thus cutting the relation between the pavement and the air.
Here is my question: The firms that produce those chemicals generally suggest an amount of 150-200 grams per metersquare. Does anybody have any information about the minimum amount of these curing chemicals? Is the amount that is given by the producers seemed to be realistic or some marketing strategy has weight?

AASHTO says minimum of 200 square feet per gallon
I would stick to this rate and you should have good results.

3.3—Execution
3.3.1 Apply liquid membrane-forming compounds uniformly
and at the rate recommended by the manufacturer,
but at a rate as tested using ASTM C 309.
The manufacturer recommends the rate of application for the material that was used to meet the standard.

The keys are to get complete coverage and to install the compound as soon as possible.
