Surface PreparationPregunta 13 de 100
Loose, flaking paint on old siding should be handled how before recoating?
a.Painted over immediately to lock it down
b.Left in place because it improves adhesion
c.Covered with heavy caulk
d.Scraped and/or sanded to a sound, tightly adhered edge, then feathered smooth
Explicación
New paint is only as sound as the surface beneath it, so loose and flaking paint must be scraped off to firmly bonded material. Edges are then sanded (feathered) to blend the transition. On pre-1978 homes this work must follow lead-safe practices.
