For an oil-based enamel on trim, which brush type is generally preferred?
a.A synthetic (nylon/polyester) brush only
b.A foam roller only
c.A natural-bristle (china bristle) brush
d.Any brush works equally, no difference
Explicación
Natural China-bristle brushes hold and release oil-based (alkyd) coatings well and give a smooth finish, so they are preferred for solvent-based enamels. Synthetic brushes are used for latex paints because natural bristles absorb water and go limp. Matching brush type to the coating improves the finish.
