Sand the trim with a fine-grit sanding sponge. Sponges get into crevices where sandpaper can’t go and let you apply even pressure. Then apply the first coat of paint, let it dry at least 24 hours, lightly sand it again for a completely smooth surface, and apply the second coat. After each sanding, vacuum the trim, then wipe it down with a tack cloth to remove the dust.
Painters with bad reputations can avoid the problem of reference checks by giving their customers lists of relatives and friends.  The people will say great things, and the customer won’t be the wiser.  The best way to avoid this smoke and mirror trick is to ask specific questions about the project. If the reference seems hesitant, doesn’t know the details, or gives sketchy responses, be skeptical.  House Painting Westminster Colorado
