Sealing wood surfaces is a great way to protect them. There are several methods for sealing the wood, but the two best are polyurethane and stains.
If you want your wooden furniture to look superb, knowing how to seal wood is necessary.
Wood is the top widely used building material in the world. It has been used for many purposes for centuries. In many countries, wood is also the key ingredient in producing furniture and all related products.
How to seal wood for outdoor use
An exterior stain is a popular coating for outdoor wood. This product can protect from water and sun exposure. You don’t want the furniture to decay due to a lack of protective sealing.
You can pick water or oil formulations. The resins are capable of penetrating the pores and adding color. They also prevent damage that comes from the weather. Moreover, the wood texture will look bright and shiny.
The second type of sealer is a film-forming sealer that adheres to the wood surface. The treatment gives furniture a high gloss appearance but allows the grain to highlight naturally.
They provide a durable, attractive, and satin finish.
How to seal outdoor woodcarving
You will need a brush to apply the sealant. In general, it must be big enough to cover sufficient areas. However, remember that the brush is not too large to avoid adding sealant into the crevice.
You only apply a coat on wood cleaned and sanded previously. After the coating is done, let the wooden carving dry in an open area.
After that, sand the wood surface with sandpaper. This step is because the pores absorb the sealer, thickening the grain. It becomes raised and protrudes from the surface.
When you have sanded the first layer to smooth the surface, you start applying it to the second section. It is unnecessary to sand the surface again after application, as anything more than one layer is.
However, it is often recommended to add sealant to the carving for extra protection and a beautiful appearance.
After three or four coats, the protection should be sufficient for one year, depending on how much the seal deteriorates over time.
Moisture does not harm your wood but the sun. Therefore, keep the furniture or wood out of sunlight directly.
How to seal painted wood
Check the last layer of the coat has dried completely. Lightly sand the surface with sandpaper, applying only enough pressure to soothe out all rough spots. Use a clean cloth to remove the dust.
Dip a paintbrush into the sealant container. If necessary, gently swirl the sealant, but avoid vigorously stirring and shaking the container, as this may create bubbles. Tap off any excess sealant around the rim of the can.
Spread the sealant evenly over the surface in a single direction. When the sealant has dried, this will give a smooth surface.
If bubbles or drops appear, smooth them carefully with the brush while the layer is still wet. Carefully sand the dry layer with grit sandpaper.
Add the second coat. Let it harden, sand it down and repeat the process up to three layers. You do not need sand after the last coat. Let the finished piece cure overnight or based on product instruction.
How to seal white painted furniture
There are various methods for sealing painted wood or furniture. The sealer you pick depends on the method you try.
Read the instruction to get a better understanding. Pay attention to the temperature of the sealer. Before applying the sealer to a surface, stir it properly.
If you apply the sealer with a brush, use long strokes. A paint sprayer is a good technique to achieve a flawless finish on your furniture.
Do not use oil-based paints if you choose a white coat for furniture. The reason for this is that they turn yellow after a few periods. Oil paint is resistant to dents. You pick this one if the downside is not the problem.
How to seal wood for indoor use
Concerning protecting wood, both varnish and polyurethane are reliable solutions. Polyurethane is known to create a glossy finish.
Choose the best polyurethane for your wood sealant from the various options. Oil-based product is the highest and is often used for outdoor furniture.
On the other hand, water polyurethane is usually used to protect indoor furniture.
After cleaning the surface, apply the first polyurethane coat to the wood with a dry towel. You can also use a paintbrush for this.
You should make long strokes to cover the surface evenly with the coating. Remember that you must paint continuously from one side to the other.
Repeat the process for more coats until you feel satisfied. Leave the wood to dry and sand it with sandpaper.
Using shellac to seal the wood
Shellac is another choice to seal the wood. It creates barriers as protection and adds a warm feeling.
While the properties are not much beneficial in terms of overall longevity, shellac can give a smooth finish when used with specific wood types.
Shellac is applicable in conjunction with sealants such as varnish or oil, which is a popular option. If you want a particularly smooth and warm finish, shellac is a fantastic alternative.
You must clean the wood, especially the blind spot and crevices. The next step is you prepare to paint or cloth. Stir the can of shellac until it blends completely. You just brush directly and repeat to get more layers.
Seal the wood with Tung oil
Tung oil is an alternative sealant for wood furniture. In the market, such oil is easy to find, and you may rub it directly by hand.
There is also another option from linseed oil. The product will create an attractive finish and has been around for centuries.
You start by wiping the dust off the surface to remove any defects. Use sandpaper to smooth the surface. Mix the oil sealant completely. Dab into the sealant with a bristle brush and apply it immediately to the wood.
Repeat the second coat after the first one is soaked and saturated. You implement more coats to get a durable and long-lasting finish.
Use a dry cloth to wipe off any residual. Wait until the paint is dried. You sand the wood to get a smooth finish.
