Vetoprime EP490 is a universal primer for the Vetorep and Vetotop Coatings product range. It is applied on prepared concrete and cementitious substrates to seal the substrate enhance bonding with topcoats. The product can be used as a stand-alone product in internal applications as a seal coat to harden cementitious surfaces and prevent dusting. Vetoprime EP490 is a two-component solvent-based epoxy resin that has penetrating properties making it ideal for concrete substrates.
Vetoprime EP490 must be applied to a sound, clean and dry surface to achieve maximum bond strength between substrate and coating/repair products.
Concrete substrates should be at least 28 days old, and at a 75% or below relative to humidity of the concrete. Laitance deposits on new concrete are best removed by light grit blasting, mechanical scrabbling, or grinding. Where heavy contamination by oil and grease has occurred or existing coatings are present, remove all contaminants entirely.
Mix Vetoprime EP490 as supplied. Add the entire content of the hardener container to the base container and mix thoroughly for about 2 minutes. Once mixed, apply Vetoprime EP490 immediately in a thin continuous film using a stiff brush or a roller.
Avoid over-application and puddles. Allow Vetoprime EP490 to become tack-free before applying the epoxy coating (unless otherwise specified), but keep well within the open time specified for the given temperature. As a general rule, the hotter the substrate, the quicker the primer will become dry.
Clean all tools and equipment with Vetonit Solvent XX400 immediately after use.
