Painting tips & tricks of the day

Wood preparation before painting
When we paint wood, we're decorating it, but we can also protect it for good if the surface is prepared properly. New wood must be sanded along the grain. Painted or stained wood as well, unless you strip it down to its bare surface. Pores, screw and nail holes can be filled with plastic wood or joint compound, according to the case. Remove all accessories to minimize trimming. Paint over knots with orange shellac to hide them forever. Finally, be sure that the wood is dry and clean.

Painting old moldings
Over the years and after many coats of paint, door frames, windows and wall molding joints are no longer well defined and easy to trim. Carefully trace over the joints with a plasterboard knife using a yardstick if necessary. The traced cut will act as a paint dam? as long as you don't use too much.
