Surface Preparation (or Surface Prep for short) is the process of cleaning and readying surfaces for new coatings.Due to varying attributes and performance characteristics of the many coating types,surface preparation requirements can also be unique from project to project.Below is a general guide for Surface Preparation 1.Removal of Old Coatings
Removal of Old Coatings.For most surfaces being completely recoated,its important to removeRemoval of Surface Contaminants like Chlorides,Acids and Oils.Surfaces in industrial settingsRemoval of Loose parts of the Surface.Before applying new coatings,its important to removeAccurately Profile the Surface.Nearly all coatings last longer when the surface they are beingEnsure the Newly Prepared Surfaces are Dry.Coatings will have issues adhering to surfaces that5 Preparation of Surface - IN.gov5-1 CHAPTER FIVE PREPARATION OF SURFACE HMA pavements may be placed 1) Over existing pavements,either HMA or concrete 2) On newly constructed aggregate or HMA base courses 3) For widening contracts,on a combination of existing pavement and a base course The existing surface is required to be compacted,stable,and free from
