Surface Preparation第 25 / 100 题
What is the correct order of the basic surface-prep steps for a typical repaint?
a.Prime, clean, scrape, sand
b.Clean, scrape/remove loose paint, sand/patch, then prime
c.Sand, prime, clean, scrape
d.Prime, sand, clean, scrape
解析
A logical prep sequence is to clean the surface, remove loose and failing paint, sand and patch defects, and then prime bare areas. Cleaning first prevents grinding contaminants into the surface, and priming last seals the prepared substrate. Following this order produces a sound base for the finish coats.
