IMPORTANT!! prior to sanding any composite part that came from a mold you must remove all wax and release agent. Use a solvent to wash down the surface and then wash again with our EkoClean before sanding. If you don't follow these important steps you risk the chance of contaminating the surface by pushing the wax or release agent deep into the surface with the sand paper and you will have adhesion problems.
E620 Grey EkoFill may be used as a filler/primer for additional UV protection ** DO NOT USE E620W WHITE EKOFILL** Do not wet sand EkoFill
Normally we recommend EkoPrime. It can be applies directly out of the can for a high build and then diluted 10% with Distilled water for a smoother final coat application. EkoPrime may be wet sanded.
EkoFill is a water base latex material. This combination not only makes a high build primer that remains extremely flexible, but also provides an excellent ultraviolet barrier for your fabric or composite surface.
