Systems Specifications Internal Mild Steel

Surface Preparation: Ensure surfaces are degreased and free of contamination using A925- Metal degreaser

(follow instructions as per data sheet).

Ensure all Corroless data sheet preparation procedures are strictly followed such as spread rates, abrasive blasting, power tool

cleaning and water jet standards etc. Apply 1^st coat within 4 hours of abrasive blasting. Practical coverage is project dependent.

Ensure surfaces are free from preparation debris and are clean and dry.
