Surface Preparation: Ensure surfaces are degreased and free of contamination using Protective Paints A925 - Metal degreaser
(follow instructions as per data sheet). Ensure all Corroless data sheet are strictly followed. Ensure surfaces are free from
preparation debris and are clean and dry. Apply 1st coat within 4 hours of abrasive blasting. Practical coverage is project dependent.
