Coating Floors Over 10bs of MVE:
We recommend shotblasting or other mechanical profile be done on concrete surfaces that have an MVE Reading of between 10 and 20lbs. A coat of 4100 primer should also be used over slabs that have 15lbs or more of MVE. DO NOT USE ON FLOORS WITH HIGHER THAN 20LBS MVE!
Coating Over Tight Hard Troweled Concrete
Thin the 4100 with xylene (use acetone in strict AQMD districts) up to 40% and apply at the same coverage rates. When dry, apply a second coat at full strength.
Chip Window:
We have found that it is best to allow the 4150 lay on the floor for 30 minutes before throwing the chips (when it is applied directly over concrete). If chipped sooner then you run the risk of the 4150 wicking up into the flake as well as down into the concrete. This will leave a ghosting effect which makes the concrete substrate visible around the edges of the flake.
Accelerating:
Use 41 accelerator to increase the set time in cold environments. at 50 degrees 1 accelerator will cause the material to dry as if it were 70 degrees, use 2 accelerators at 40 degrees. Do not use accelerators to shorten the set time so the job can be done faster because this can decrease the adhesion and MVE protection.

Hi John-  Thank you so much for your advice and for patiently answering all my questions regarding my application of Roll on Rock 2 to my home garage floor.  As you know, I was an inexperienced DYI home applicator but your product was easy to apply and looks GREAT!  The customer service was exceptional and I love the new flooring.  This product is infinitely better than the home store brands.  Thank You Again!!
