SigmaGuard 790 provides a coating that is easily cleaned so all chemical build up or residue can be removed efficiently, helping you maintain the surface.
PPG SigmaGuard 790 can be applied easily using brush, air or airless spray to produce a greenish, grey, glossy finish. After 3-4 hours you will have a high quality finish that is dry to touch and after 16 hours you will be able to recoat the surface.
