Wet Spray Painting is used to protect steelwork once it has been shot blasted. Application is via airless paint pumps. This method is extremely effective as large surface areas can be coated much more efficiently and evenly than using equipment such as brushes or rollers.
Wet application ensures good adhesion, penetrating into the shot blasting profile, any pits and crevices and producing a thick uniform coating, reducing the number of coats required.


Pro-Tect Coatings are able to give advice to customers, concerning the correct paint specification to cope with the toughest and most challenging situations / environmental conditions, e.g. salt, heat, humidity, UV, chemical etc.
Specifications range from shot blast and prime only, to full painting systems designed to suit your specific needs.
