Most wood species require a minumum of one coat of primer before painting to seal the pores, ensure even coverage and encourage wear. Stained knotty pine is much more difficult to paint than fine-grained oak, but you can attain professional-looking results with the proper products. Wood stain can seep through paint, so can dark-colored tannins in the attribute knots of walnut. This type of bleed-through leaves dark, yellow stains onto the painted surface which doesn’t wash off. Adding more paint usually won’t seal the stains out; fortunately, the ideal primer will.

Clean the stained knotty pine surface with oil soap for wooden surfaces or gentle dish soap and a sponge. Rinse the wood with a sponge dampened with plain water. Allow the walnut dry.

Sand the wood by hand, using fine-grit sandpaper. If the place is very big, use a fine-grit sanding sponge or sanding block.

Vacuum off the sanding dust with a utility vacuum cleaner. Remove remaining particles with a slightly damp rag.

Apply painter’s tape around the perimeter of the pine post to protect the surrounding area from primer and paint, if needed. By way of instance, if you’re getting ready cupboards, tape off the surrounding wall. If you’re painting a paneled wall, then tape off the baseboards or flooring.

Open a container of shellac-based paint primer and then stir it gently, using a paint stir stick.

Apply primer round the borders of the pine post, using a fine-bristle, trim-style paintbrush. Use the bristles of the paintbrush to apply primer inside the holes and cracks in and around the knots. In the event the walnut is paneled, use the trim brush to prime the seams between panels and anyplace else a paint roller won’t reach.

Decide on a paint roller pan liner at a paint pan. Fill the pan with shellac-based paint primer. Fit a medium-nap roller cover onto a paint roller and roll it through the primer to load it.

Roll primer onto the knotty pine post with even, overlapping strokes to ensure smooth coverage.

Scrub the paintbrush with denatured alcohol and then wipe it dry onto a rag.

Allow the primed pine post tender. Shellac may call for overnight drying period.

Open and stir a container of latex paint.

Paint around the perimeter of the Product. Ensure to paint inside the knots, crevices and seams with a paintbrush as you did with the primer.

Roll on at least two coats of paint with a new, medium-nap rollercoaster. Permit the paint to dry between coats.
