Systems Specifications Steel pipes

 

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