Oak is valuable in the construction of interior wood accents and trim. With its hard, dense grain, oak is durable and withstands years of use. Unfortunately, it's also pricey. Pine is a softer wood, often stained and finished to match the colour of oak. If you have oak cabinets, you can finish new pine windows and doors to match the oak colour, but upon close inspection, you will still notice the difference in the wood grain patterns.
Sand the new pine windows and doors with a 220-grit foam sanding block. This won't take too long, because the doors and windows come pre-sanded from the factory.
Apply a sanding sealer, sometimes called pine sealer, with a brush as directed on the container. The sealer is clear, and it allows the pine to absorb the oak stain evenly.
Sand the pine doors and windows again after the sealer dries completely. The sealer will raise the wood grain, but you can quickly smooth it down with a 220-grit sanding pad.
Stain and finish
Apply the wood oak stain to the pine doors and windows with a stain applicator pad. Dip the pad into the liquid stain, and smooth it on the wood evenly.
Let the wood stain remain on the pine until the wood matches the colour of your oak cabinets, and then wipe it off with clean, soft rags. Repeat the staining and wiping procedure until you've completely stained the doors and the windows.
Apply a thin layer of finish coat. The type of finish coat you apply should match the finish on your oak cabinets. Polyurethane, varnish and shellac are commonly used on cabinetry, but if you're unsure what type of finish is on your cabinets, ask a finish carpenter or a furniture expert.
Sand the windows and doors one final time after the first application of a finish coat dries completely. Like the sanding sealer, the first finish coat may raise the wood grain slightly. Use a very fine, 400-grit sanding pad, and sand in the direction of the wood grain. Use a very light touch -- the sanding pad will barely be touching the wood surface.
Apply one or more additional finish coats, until the doors and windows match the finish of your cabinets. There is no need to sand again.
Take a pine board to your paint and stain centre, and ask the paint sales expert to test different shades of oak stain on the board. Compare the stain samples against your cabinets before choosing a stain.
Do not dispose of wet stain rags; they can spontaneously burst into flames. Instead, spread them out to dry, and then throw them away in an outdoor rubbish bin.
