Reactamine 5050 is designed to be used with light weight solid surface fillers such as thermoplastic resins. This polymer provides excellent weatherability, color retention (UV stability), flexibility, water & abrasion resistance, and excellent solvent resistance. It is recommended to use Carboguard 1340 WB as a primer on concrete. After the Carboguard 1340 WB is dry to the touch, Reactamine 5050 should be applied with the desired solid surface filler, or vinyl flakes. Once the Reactamine H 5000 has cured, it is recommended that it be top-coated with Reactamine H SLR or Sanitile 985 PA.
