MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 50-90⁰ F. Avoid low temperatures and large temperature fluctuations in storage as these conditions could cause possible product crystallization.

SURFACE PREPARATION: All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble free bond to the substrate.  We recommend that all loose concrete, previous joint compound or other foreign material be removed to leave a clean sound joint at least 2” deep.  For best results, edges should be sawcut and a one inch backer rod should be placed into the joint leaving approximately 1 to 1 1/2 inches from the top of the backer rod to the top of the joint.

PRIMER:  No primer is necessary.  This material is self-priming.  However, any suitable primer can be used.

PRODUCT MIXING:  It is important that the material be mixed  before using. Therefore, take a few extra minutes to make sure adequate time has been taken to mix the two components together thoroughly. Improper mixing will cause an incomplete cure and soft spots in the joint. Mix one part by volume part A to one part by volume part B in an oversized mixing container. Mix well with slow speed mixing equipment such as a jiffy mixer until material is thoroughly mixed and streak free.

PRODUCT APPLICATION:  Apply the mixed product by pouring the mixed material into the expansion joint to be repaired. Remove any excess material with a putty knife or similar tool prior to curing. Alternatively, it may also be suitable to let the product become tack free in the joint and then using a razor scraper to cut off or shave the excess above the floor plane. Maintain temperatures within the recommended ranges during the application and curing process. When temperatures are lower, allow more time for this material to cure.

RECOAT OR TOPCOATING:   No recoating or topcoating is necessary.  However, if you opt to topcoat the applied joint compound, allow it to cure before topcoating.  It is not necessary to prime over the joint compound prior to topcoating, but adhesion can be improved by roughening the joint compound prior to coating. Many epoxies and urethanes can be used.  In some instances, especially when excessive expansion joint movement is involved, topcoats may chip or crack.  However, most epoxy or topcoat products will adhere to the joint compound very well. It is recommended to apply a test area with the system to be applied before undertaking the entire project.

CLEANUP: Use xylol.

SURFACE CLEANING: Caution!  Some cleaners may affect the color of the floor installed Test each cleaner in a small area, utilizing your cleaning technique.  If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the area to light duty use and non-harsh chemicals until the coating is fully cured (see technical data under full cure).  It is best to let the repair area 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.
