How should wood preservatives be applied or soaked correctly?

Why use wood preservatives?
As a natural material, wood is susceptible to mold, insects, moisture and ultraviolet rays, leading to rotting, deformation and even breakage. Wood preservatives effectively resist these destructive factors by forming a protective layer on the surface or inside of the wood, improving its stability and service life. In this context, more and more wood preservative manufacturers continue to develop safer and more environmentally friendly products suitable for a variety of environments and wood types.

Operation steps and precautions of the brushing method
The brushing method is the most common wood preservative treatment method, which is suitable for small-scale household operations or large components with complex structures that are inconvenient to soak. The specific steps are as follows:
1. Surface pretreatment
Before brushing, be sure to clean up obstacles such as dust, oil stains, old paint, etc. on the wood surface. If necessary, polish the wood surface until it is smooth to improve the absorption effect.
2. Drying treatment
The wood should be kept dry, and the moisture content should be controlled below 15%, which is more conducive to the penetration of preservatives. Wet wood will affect the adhesion and absorption of preservatives.
3. Apply evenly
Use a brush or roller to evenly apply the preservative on the wood surface, including key parts such as joints, sections and grooves, for at least two times. Wait for the wood to dry before the next application between each application.
4. Ventilation and drying
After applying, place the wood in a well-ventilated area without direct sunlight to dry naturally to prevent the preservative from volatilizing quickly or crusting on the surface.
Many wood preservative factories provide customized formulas for different wood species. Users can consult professional advice based on their own usage scenarios before purchasing.

Operation process and scope of application of the immersion method
Compared with brushing, the immersion method is more suitable for large-scale and simple-structure wood preservative treatment, especially in outdoor gardens, guardrails, dock materials and other fields.
1. Container preparation
Prepare a preservative tank with sufficient capacity, which can be made of stainless steel or plastic to ensure that there is no chemical reaction with the preservative.
2. Wood pretreatment
It also needs to be cleaned and dried, and special attention should be paid to the treatment of the sections and cracks to increase the absorption depth.
3. Soaking time control
The soaking time usually ranges from 30 minutes to several hours, depending on the density of the wood and the concentration of the preservative. The soaking time for softwood can be shorter, while that for hardwood can be appropriately extended.
4. Dehydration and drying
After soaking, take out the wood and place it vertically to allow the excess preservative to flow out naturally to avoid cross contamination caused by stacking, and then dry it in a cool place.
OEM manufacturers of wood preservatives usually provide soaking-specific concentrates or finished liquids according to customer needs, with instructions for use, so that customers can process them in batches.

Preservative selection and use recommendations
When selecting preservatives, the use of wood (indoor/outdoor), type (pine, eucalyptus, oak, etc.), construction method and environmental protection requirements should be considered comprehensively. For users who pursue economic benefits, choosing a wholesale channel for wood preservatives can effectively reduce procurement costs. Such channels usually provide multi-specification packaging, anti-mildew and anti-insect integrated products and technical support.
Special attention should be paid to the toxicity level of preservatives, and low-toxic, low-volatile and environmentally friendly products should be given priority. For wood that needs to be painted or glued later, it is recommended to use a preservative that is compatible with the subsequent process.

Whether it is a brushing or immersion method, standardized operation and reasonable material selection are the key to ensuring the wood preservative effect. During use, the technical parameters provided by the wood preservative manufacturer should be strictly followed to avoid overdose, incorrect dilution or improper use. For users with large construction batches and diverse scenarios, it is recommended to establish a cooperative relationship with a professional wood preservative factory or wood preservative OEM service provider to obtain a more stable supply chain and technical support.
