Walnut is a very classy wood. Its unique dark chocolate color is always liked by the woodworkers, craftsmen, and cabinetmakers. However, in terms of hardness, it ranks only 5 on a scale of 10. The wood features open pores and these respond to any sort of finish readily. The finish of the timber can be done with or even without any stain. Whatever, you do, it’ll give a warm ambience just because of its complex grain pattern. This unique pattern ripples and wanders.
Things to take care of for best finish to the wood
To ensure the finest finish for your modern walnut cabinets, here are the factors that must be considered.
- Preparation– Surface preparation is one of the most vital things as it comes to walnut finishing. The surface must be thoroughly sanded first to make it smooth. This can be done with a handheld oscillating tool or hand block along with a sanding accessory. After the initial sanding is done, sand over the surface by hand with the help of 180-grit sandpaper. Make sure you sand it parallel to the grains during final sanding. This eliminates small swirls a well as cross-grain scratches that you can’t see easily. But they show up in the later phase if are not eliminated properly. Once the final sanding is done, apply any stain as per your choice.
- Lacquer – This is the best to finish walnut kitchen cabinets perfectly. Just apply two coats to seal and protect the timber. Lacquer dries quickly and it’s user-friendly. Use a pressurized spray or airless tool for the application. Pour lacquer in the spray gun container. Hold it 8 inches from the wood at a 300 angle. Spray wet coat evenly on the walnut. Let it sit for 30 minutes and then again sand the timber by hand with a folded sandpaper of 180-grit. Apply another coat just as you’ve done initially. Though two coats are enough, you can apply even four coats for a deeper finish. Sanding after each coat is not essential though it’s essential after the first one.
- Linseed oil – Now it comes to linseed oil that can penetrate the wood pores. It hardens into it. Though it takes longer for the walnut to finish with oil it can better work to waterproof the wood than lacquer. Once the sanding is done, moist the wood surface with the oil. Let the linseed oil sit for half an hour and then wipe it off. Wait for 24 hours and repeat. But this time, you need to wipe off the surface right after applying the oil. Now apply another light coat and wipe off immediately. Do this once a week for one month. Then do the same once every six months to keep the wood protected and the finish intact. If you look for extra gloss, rub the timber with the palm whenever possible between coats of linseed oil.
If you want to protect your walnut cabinet and retain its finish as a new one, use lacquer or linseed oil in the described way for polishing. You may also burnish the wood.
