A primer is not necessary with the 55-1 system. However, on surfaces which are too porous or difficult to wet, PrimKote 8006-1 can be used to insure best adhesion. A rod, paddle or power mixer are all adequate if properly used. Generally, it is measured in masses of 100-500 grams. Smaller masses, or thin layers need a much longer time to harden.
Higher temperatures shorten the pot life.
Application is easy. In most cases, any blade-like tool, such as a trowel or scraper, is used to spread, fill, resurface or finish. If a bead is needed, it can be dispensed from a caulking gun. It is virtually free of shrinkage and can be applied in any thickness. The hardening reaction generates heat and is accelerated by heat.
