PRODUCT STORAGE: Product must be stored in an area that will bring the product to room temperature prior to using. Continuous storage should be between 60 and 90 degree F. Keep from freezing

SURFACE PREPARATION: Preparation methods may vary depending on the system being applied. When installing a one or two coat thin build system (3-10 mils dry) mechanical scarification until a suitable profile is achieved is recommended. Floor systems that are higher than 10 mils dry, a fine brush blast (shot blast), is recommended. To assure a trouble free bond, all dust, oil, dirt, foreign contaminants and laitance must be removed. It is recommended to perform a moisture test to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. Once 24 hours has passed, and the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause disbonding. This test does not guarantee, however, that there may not be future hydrostatic pressure issues in the future.

PRODUCT MIXING: Kits should be mixed in their entirety. Pre-mix both Part A and Part B before making any batches. If partial kits are to be used, the product mixing ratio is 2 parts A to 1 part B. After the two parts are combined, mix well with slow speed mixing equipment until the material is thoroughly mixed and streak free, avoid whipping air into the product when mixing. Improper mixing may result in product failure. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

Use of an improper drill mixer can result in curing problems if the hardener also called activator (Part B) is not thoroughly blended with the resin (Part A) which can cause some areas on your floor to remain soft and not harden properly.  DO NOT USE A PAINT MIXER.  Most mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can result in the same problems as using a paint mixer.

PRODUCT APPLICATION: Use a brush or 3/8” nap roller to apply the mixed material. Maintain temperatures within the recommended ranges during the application and curing process. Properly prime the substrate. It is best to maintain a wet edge to avoid roller marks. Roller marks cans also occur if the product is put down too thin, or if over rolled. The easiest way to install this product is, after mixing it, pour the product into a flower watering container, then pour the product onto the floor as evenly as possible. Do not pour it all out onto the floor, only pour out in small sections. Once you pour out the first section, begin rolling it out evenly, the spread rate is 300-350 sq.ft. per gallon. Do not over roll or cross hatch, it’s not necessary, and will cause roller marks. When you are near the end of the first section, then take the watering container and begin pouring out a new section, pouring directly into the ribbon that remained. Continue this process until the entire floor has been rolled out. Direct sunlight or high temperatures may cause visible roller making during application. Applying the product too thin and over rolling the product, may result in roller marks in the floor. Avoid applying uneven thicknesses, this may cause variations in gloss. The pot life may seem to be longer, however, it is not recommended to apply product beyond one hour of it being mixed. After the product is mixed, the air exposure may cause skimming on the top of the product if container is left uncovered. Simply remove the thin layer, and re-mix product and apply. After an extended period of time, any product not used, may foam up and expand.

RECOAT OR TOPCOATING:Installing multiple coats of this product is acceptable. If recoating this product, be sure that all of the volatile compounds have evaporated from the coating during the curing process. Refer to the cure schedule as a guideline to follow, however it is best to test the coating before recoating or topcoating. Pressing your thumb on the coating to ensure a fingerprint impression is not visible, is a good way to determine if ready to recoat. If there is no impression visible, then coating the floor can be done. Note, colder temperatures require longer cure times before product can be recoated. Prior to coating the floor, make sure there are no contaminants exist. If contaminants or a blush exists, remove with a standard detergent cleaner and ensure floor is clean and dry prior to coating. When recoating this product with subsequent coats of urethane, make sure to apply the recoat within the 24 hour time frame. It is recommended to degloss the previous floor prior to coating to ensure a trouble free bond.

CLEANUP/FLOOR CLEANING:Use PM solvents for cleanup. When cleaning the floor, CAUTION! Some cleaners may affect the color of the installed floor. Test each cleaner used in a small area, ensuring no damage occurs. Restrict the use of the floor to light traffic and non-harsh chemicals until the floor is fully cured, refer to the cure schedule. Allow the floor to remain completely dry during the curing process.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
