EPOFLEX – Epoxy Acrylate resin Substrate & Surface Preparation

General                            Surfaces must be clean and dry. Employ adequate methods to remove
                                           dirt, dust, oil and all other contaminants that could interfere with
                                           adhesion of the coating.

Steel                                  Steel blast cleaned to ISO-Sa2½ and then primed with flexible epoxy
                                            primer or other suitable epoxy primer.

Galvanized Steel             Primed with suitable etching primer.
Concrete                           must be shoot blasted and repair cracks with a suitable sealant and then primed with a proper epoxy sealer.

This product simply requires the substrate temperature to be above the dew point. Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate. Special  application techniques may be required above or below normal application conditions

Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times. Excessive humidity or condensation on the surface during curing can interfere with the cure, can cause discoloration and may result in a surface haze. Any haze or blush must be removed by water washing before recoating. During high humidity conditions, it is recommended that the application be done while temperatures are increasing. Maximum recoat/topcoat times are 30 days for epoxies and 90 days for polyurethanes at 75°F (24°C). If the maximum recoat times have been exceeded, the surface must be abraded by sweep blasƟng or sanding prior to the application of additional coats. 890 LT applied below 50°F (10°C) may temporarily soŌen as temperatures rise to 60°F (16°C). This is a normal condition and will not affect performance.
