You can preserve an outdoor wood carving by coating it with a good quality Spar varnish once a year, which makes your carving last longer. A clear coat does not require re-coating often, but it brings no damage if you maintain it once every 2 to 3 years.
Keep your carving on an elevated surface to avoid excess moisture intake. The process allows the wood to breathe through the base. Use stones or furniture pads under the carving. Continuous airflow comes as you seal the surface with a wood stain. It protects your carving from damaging elements, and it does not only make your carving shine but gives a protective layer. More coats give you more protective coatings.
Clean and dry your wood carving
Clean your carving using a lint-free cloth. Do not use all-purpose cleaning sprays used for tables unless your wood carving has a plastic coating. Avoid using water since it creates spots and absorbs water and the peeling of the top surface of the carving.
Sticky spots require soap and water but make sure you dry the surface as soon as possible. Dip a lint-free, clean cloth in water, and add mild soap or a detergent dissolved in water.
Do not use the dripping wet. Wring the cloth as it becomes almost dry and wipe the dirt off the area. Dry the surface using a dry, clean and soft cloth.
Multiple chemicals preserve wood, although some are toxic. Wood preservatives are also known as pesticides. The process of adding preservatives takes place through a pressurized or vacuum process.
Amongst the preservatives are water-borne, oil-borne preservatives. More maintenance is on wax, and re-applications are needed. And light organic solvent preservatives. Each has its pros and cons. List down your expectations and compare them with the features of each. Water-borne preservatives are more affordable than other options.
Advantages of wood preservatives
- They make wood water repellent
- They prevent rotting and decaying
- They give a protective layer to wood against freezing or thawing
- They prevent carvings from mold, fungi, and mildew
- They prevent contamination by sealing the pores of the wood fiber
Wrapping your wood carving
Cover the wood carving with a plastic tarp as if you are covering a tree stump. If you can lift it, cover the bottom of the carving. The tarp protects elements such as dust, moisture, water, and insects from affecting the wood. It also protects the surrounding vegetation from spilled chemicals you are using to coat.
Some wood carvings are mobile, stationary, and that determines the type of storage for your items. In some cases, a thatched gazebo for carvings in sunny areas.
For stormy areas, a shade is ideal for your carvings. Some users take out their carvings during the night and keep them in a garage or storeroom. Make sure they are covered with plastics to protect them from dust.
There are seasonal carvings that you store in your backyard when not in use. Cover them and take note of the natural elements that dominate in your area. Small carvings are in inboxes. Keep your carvings from fireplaces and do not allow them to rub against each other.
A rotary tool is ideal for sanding carvings. The carving should be of hardwood, and if the wood is soft, the rotary school becomes too aggressive to give positive results.
The chances of distorting the shape of the carving are high, and the overall quality of the carving is disturbed. However, that does not mean you should abandon softwood.
Use folded-up sandpaper as an alternative. A detail sander is less aggressive and has fast sanding. Rubber grips are for curved edges, and the converted oscillating toothbrush is less aggressive and for tight spaces.
Sealing wood carvings increases the life of your items. It is 8deal on outdoor furniture since it is more exposed to the natural elements. There will not be a need to replace the carving in a short period since that is avoidable.
There are water-based wood sealers and oil-based sealers, and they come with their disadvantages. Match your wood type with the ideal sealer.
Wax comes with advantages and disadvantages on outdoor wood furniture. It gives a beautiful finish to your wood carvings, and it is easy to apply and protects your carvings from scratches.
Wax makes your items look new. Depending on the type of wax, some are non-toxic. Research more on toxic-free waxes. Wax penetrator through multiple layers of wood, and that gives additional protection to your carvings.
More maintenance is on wax, and re-applications are needed. However, they make your carvings look dull as the layers increase. It is difficult to remove since it penetrates through layers of wood, is affected by heat, and stains wood.
Paint lasts longer on wood carvings, and that requires less maintenance. The wood paint soaks into the open wood pores and plugs them. That slows down the drying process and helps to reduce and prevent checking and splitting. However, it traps moisture.
Factors that affect outdoor wood carvings
The nature of wood leaves room for splits or cracks, although that does not happen with every carving. It depends on the type of wood used, and carvings react differently over time. What causes cracks is the change of weather, and that includes humidity levels.
As the humidity changes, the outer rings lose moisture, and that leads to cracks. However, add a coat of preservatives. The wood coat is either paint or stain, and it soaks into the pores and plugs them. That exercise slows down the drying process hence fewer chances of splitting.
A coat of spar urethane regulates excessive moisture that the carving takes in or loses. Bear in mind that the procedure does not stop your carving from breathing as it releases moisture. Keep your carving on top of stones or furniture pads to keep the airflow continuous.
Rain and sun
When your carving is outside, you have to deal with the rain and the sun. Rain does not cause rot if there are times the sun comes between the storms. Consistent sunny days affect the carving due to UV rays, and they are damaging to wood.
Damp wood is a host for fungi that causes rot. That is why outdoor wood items such as fence posts are treated with preservatives. Drill holes near the base of your carving, and insert rods made of borate. It contains a mineral that prevents rot, controls termites and ants. As borate moves, moisture disappears as well. Even if the carving has been rotting, no further rotting is allowed with borate.
If your carving has contact with the ground, the chances are high that it cracks, rots, or splits due to moisture absorption. That is why you have to look for flats, stones, water-borne preservatives that are more affordable than other options. or furniture pads to raise your wood item from the ground.
There is enough air that circulates, and it keeps the carving dry. The surface of your item has to be breathable. Grass and soil cause rot since they are carriers of moisture and mildew. It is ideal for keeping your carving under a shed during winter. Placing your carving near a fireplace protects your wood carving from natural elements but is not close to fire since it is damaging.
Maintenance and repairs
If you fail to maintain your carving and repair it whenever you notice damages will not keep your wood carving in good shape. Cracks are filled in using a small piece of wood. Using a piece of wood with a similar color brings out a perfect finish, making the patch less visible. A combination of a patch of the same color and spray paint results in a flawless finish.
