Usage Tips for Body Shops

1. Substrate Preparation: thoroughly degrease the surface (suitable silicone degreaser), sand the substrate according to recommendations (e.g., P180–P240 on old paints or fillers), then dust off and degrease again.
2. Mixing: follow the mixing ratio indicated by DeBeer with the recommended hardener (MS or HS hardener compatible with 8-145). Optionally add thinner according to the desired viscosity and temperature conditions.
3. Spray Gun Application: apply 1 to 3 cross coats respecting evaporation times between coats. Adjust the pressure and nozzle of the spray gun to your equipment and type of work (localized or full panel).
4. Drying and Sanding: allow to dry according to the technical data sheet (air or forced drying). Then sand with suitable abrasives (e.g., P320–P500) to achieve a perfectly smooth surface.
5. Overcoating: after drying and sanding, the 8-145 primer can be overcoated with the DeBeer base coat (waterborne or solvent) and then with the appropriate clear coat.
