When using wood to build various structures, after completion, it is necessary to adopt certain protective measures for the wood to improve the life of the wood and extend the service life.
1. Start by choosing the right wood
The most effective way to deal with it is to choose the right material from the beginning and carry out a detailed design, taking into account the potentially harmful factors in the environment in which the wood is located, proper ventilation and reducing humidity in the environment. The physical properties of wood are affected by the tree species, and the selection of the appropriate tree species and the necessary maintenance can usually last for more than 50 years. When choosing, consider the hardness, density and other physical properties of wood, such as European ash, European ash has high availability, density in 680~750 kg / cubic meter, moderate hardness, poor resistance to fungi and insects erosion; Walnut has some resistance to fungi, but it changes color when exposed to alkaline glue and is not suitable for outdoor use.
2. Avoid the erosion of wood-eating insects
Chemical insecticides, such as Antiborer™ 10EC insecticides, can be applied to wood, taking into account the degree of possible damage to wood and environmental protection requirements.
3. Avoid the erosion of fungi
Once the moisture content in the wood exceeds 20%, its humidity is already too high, which can easily lead to the breeding of fungi, so that the hardness and resistance of the wood decrease. At the same time, some tree species are susceptible to fungi erosion and discoloration, so it is necessary to use fungicides in time or treat wood with preservatives first.
4. Excessive exposure to sunlight
Wood furniture, decoration and other structures will change the original color of wood after long-term sunlight, and metal pigments or breathable paints can be used to protect wood. When choosing protective products, pay attention to the choice of products that can penetrate deep into the wood, only stay on the surface of the protective products, more suitable for wood in a good environment, no high humidity, no termite erosion troubled environment.
Common products for whitewashing wood surfaces:
varnish
Refers to resin solutions containing water or organic solvents. It is a transparent coating, and water-based clearcoats are more environmentally friendly than oil-based clearcoats. In order for the wood to retain its brilliance and color for a long time, it is necessary to apply varnish to the surface, but this method is not suitable for outdoor wood. Outdoors, you can use ventilation holes to allow varnish to penetrate the wood, making it more protective.
paint
Paint forms a UV barrier on the surface of the wood and is more effective than varnish, but obscures the aesthetic characteristics of the wood itself.
wax
Wax is only used for indoor processing of wood, its protective properties are almost nothing, but it is a non-polluting material, waxing is simple.
