Usage Tips for Bodywork Professionals

1. Substrate preparation: carefully degrease the surface (using a 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 desired viscosity and temperature conditions.
3. Spray application: apply 1 to 3 cross coats respecting evaporation times between coats. Adjust spray gun pressure and nozzle 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. Topcoating: after drying and sanding, the 8-145 primer can be covered with the DeBeer base coat (waterborne or solvent) followed by the appropriate clears.
