Finished fire retardant coating is a new type of coating that integrates decoration and fire protection. Because its advantages are obvious compared to other coatings, many people choose this kind of fireproof coating for painting, but many units of surface-type fireproof coatings are coated. The cover is not very well understood, and the unreasonable construction has led to the failure of the construction of the facing fireproof coating.

Finished fire retardant coating is a new type of coating that integrates decoration and fire protection. Because its advantages are obvious compared to other coatings, many people choose this kind of fireproof coating for painting, but many units of surface-type fireproof coatings are coated. The cover is not very well understood, and the unreasonable construction has led to the failure of the construction of the facing fireproof coating.
Then we can classify the following types of fireproof coatings:
When the surface of the plywood is coated with a first-grade facing fire-retardant coating, it can be used as a B1 decoration material; when the plywood is used for ceiling and wall decoration and does not contain objects such as electrical appliances and wires, it should be coated only on the outer surface of the plywood. When the plywood is used for ceiling and wall decoration and contains electrical appliances, wires and other objects, the inner and outer surfaces of the plywood and the corresponding wooden keel should be coated with fireproof coating or flame retardant impregnation treatment to achieve B1 grade.
After coating the first-grade facing fire-retardant coating, the wooden decoration material can reach the B1 level; it must be coated on the side of the possible fire surface; the wood decoration can be treated to the B1 level by the flame-retardant immersion treatment method.
The coating of the facing fire-retardant coating is not simply applied a few times. To achieve the first-grade facing fire-retardant coating, several hard indexes must be met: the flame-resistant time ≥ 20 min and the flame propagation ratio ≤ 25 , mass loss ≤ 5g, carbonized body ≤ 25cm?.
Therefore, in the case that we need decoration and fire safety, choose the decorative fire-retardant coating to solve, then we also need to follow the specifications.
