Whether the woodworking board ceiling needs to be brushed with fireproof coating on both sides

The function of the coating is to protect the wood, decorate, achieve a certain performance, and avoid the long-term high temperature of the wood, causing fire.

This is not necessarily, depending on your construction situation. If it is a home renovation, of course, it is better than nothing. And if it is a project or a public place, it must be treated with fire prevention.

Because the final fire protection is to be accepted, the general minimum requirement is B1 flame retardant level. Fireproof coatings have been gradually replaced by new fireproof boards, such as the current Tianhua sanding glass magnesium board, with A1 non-combustible level, generally using mm ceiling construction, no need to be in the back and forth construction, or more convenient and cost-saving.

On both sides, whether a combustible material needs to be coated with fireproof coating in construction is not bound by specific specification clauses. The fire-retardant coating of blockboard depends on the installation site of the board, the need for the fire-resistant grade of the room and the performance of the fire-retardant coating used.

For example, the base layer of ordinary wainscoting is not needed. If it is a ceiling for a first-class fireproof building, the fire resistance limit he needs is 30 minutes, and he needs to choose the paint and coating thickness according to this requirement.

Generally, according to the fire regulations, it is necessary to paint all of them.

Well, yes, now light steel keels are generally used, and it is also necessary to brush fireproof coatings, the cost is about the same, and it is more lightweight and insured.

Yes, as required.

According to the original text of GB50354-2005 "Code for Fire Prevention Construction and Acceptance of Building Interior Decoration".

When the surface of the wood material is treated with fireproof coating, all surfaces of the wood material should be evenly painted, and it should not be less than 2 times, and the second painting should be carried out after the first coating surface is dry; The amount of fire-retardant coating should not be less than 500g m2.

It's up to you to ask for it, and it's best to brush it all. With paint you speak.
