Surface Preparation第 24 / 100 题
A previously painted surface shows widespread peeling down to bare wood. What does this MOST likely indicate?
a.The previous paint was too expensive
b.The surface was overly clean
c.A prep or moisture problem such as painting over a dirty, wet, or unprimed surface
d.The paint color was too light
解析
Peeling to bare substrate points to an adhesion failure, usually from painting over a dirty, glossy, damp, or unprimed surface, or from underlying moisture. Correcting the cause and properly preparing and priming the wood is required before recoating. Simply repainting without addressing the cause repeats the failure.
