Painting Wood Trim and Built-Ins in Older Riverside Homes

Run a fingertip along an old baseboard and feel the buildup of paint layers, the drips, and the cooking grease on kitchen built-ins. That surface is what the new finish has to grip, and the prep order on interior painting riverside crochetastic boutique reflects it. In Riverside, CA, older homes near the Mission Inn and the University of California Riverside neighbourhoods often keep original oak and fir trim, and a painting job there depends on how the wood is cleaned and sanded.
Cleaning before anything else

Degreasing comes ahead of sanding. A wipe of a household degreaser, then a clean rinse with a damp rag, lifts kitchen film, hand oils and decades of dust from the grooves of casings. Sanding over a greasy surface only grinds the dirt into the wood and the old paint.
Sanding and scuffing

Glossy old enamel needs a scuff sand with fine paper so new paint can bite. Raised chips get feathered flat. Where the original finish was oil based, the sheen is hard and needs more attention than a latex layer. A sanding sponge reaches the profiles of moulding that flat paper cannot, and tack cloth picks up the dust afterwards.
Patching and caulking
Nail holes and dents take spackle or wood filler, sanded flush after it dries. Gaps where trim meets plaster get a thin line of paintable caulk, smoothed with a wet finger, which hides the shadow line that otherwise makes trim look loose on an uneven wall.
Primer and enamel
Bare wood and stained spots take a bonding primer. Oak shows tannin that can bleed pink or brown through light paint, so a stain blocking primer is common on raw patches. The topcoat is trim enamel in a semi gloss or satin sheen, brushed in thin coats instead of one heavy one, with a light scuff sand between two coats. A thick coat sags on a vertical casing and takes much longer to harden.
Built-in cabinets and shelves
Built-ins have doors and shelves that stick if paint is applied too thick and closed too soon. Doors come off, hardware is bagged and labelled, and the pieces dry flat, with the cabinet box finished in place. Leaving the shelves open for a few days lets the enamel harden enough that books and dishes do not stick to it.
