Before operation, first clean up the attachments on the wood surface, and then choose to mix and dilute with water in proportion. Configure it as an aqueous solution, and perform the vacuum pressure method, soaking method and brush spray method:

1. Vacuum pressure treatment: It is recommended to use a concentration of 10% -15%. Vacuum pressure treatment is used to calculate the full penetration of the drug. The general drug loading is 20-30kg / m3 to achieve the national building materials and wood products combustion performance ( GB8624—2006), grade B2.B1

2. Soaking method treatment: It is recommended to use a concentration of 15-20%, with the water surface completely covering the wood as the standard soaking time of 15-30 minutes

3. Brushing and spraying treatment: It is recommended to use a concentration of 20% -25% to fully absorb the wood surface (that is, complete wetting as a standard). The brushing spraying area is 20-25 square meters / KG. It is recommended to use brushing and spraying twice. The interval between two brush spraying is 2-4 hours

Precautions:

1. The dust and dirt on the wood surface must be cleaned during operation to avoid affecting the permeability and reusability of the medicinal solution.

2. Careless contact with the skin during operation should be rinsed with water in time

3. The treated wood should not be used as a food packaging box

4.Keep away from children during handling and storage. Do not throw away used medicines and waste.
