These are the things that I have found to be the concerns of the GC's and the facility owners. If the floor coating system cannot be ready when it's needed, they typically look for some other system solution. Time, after all, is money, as the old adage goes. So fast set times become very critical in the real world.

Here are some pertinent points the contractor should establish with the owner before recommending a coating: a. durability expected of the floor. b. chemical resistance needed. c. abrasion resistance needed. d. slip resistance expected. e. budget. 2) Time: Time restraints will determine if you need to use an efflorescence blocker so you don’t have to wait 28 days. Time to completion will also be an influence. 3) Moisture: What are the moisture vapor emissions? Do you need to apply moisture-stopping epoxy primer? 4) Climate: for obvious reasons.

Then seek out specific applications of coating products where the conditions are like those to be coated. DMA sure covered the requirements! We must not forget to prepare the concrete and test for moisture vapor emissions.

Desired and required level of texture is important. Other factors might include planned cleaning methods (realistic), desired appearance, moisture vapor content at time of coating, size and layout of spaces, and turn-around requirements.
