There are some nail holes and gaps in it, so the first thing to do is to do the gypsum board base treatment. The surface of the aluminum gusset has been treated by oxidation and oil resistance, and the material does not belong to the same kind at all, so there is no need to apply latex paint.
The nail sinks into the gypsum board millimeters, and the nail hole should be treated with large gypsum when the base layer is treated.
Repair method: If the gypsum board ceiling nail hole bulging area is relatively small, first use a Phillips screwdriver to screw the exposed self-tapping screws into one by one, and then put all the exposed self-tapping screws on the anti-rust paint, and then paste kraft paper, and then make putty powder to paint. >>>More
It may be because of the yellowing caused by the dampness of the gypsum board, pay attention to the construction of the ceiling must be in a dry condition, and the plasterboard itself will be yellowed after the sticker is damp, so the bottom layer isolation must be handled well before painting.
Nowadays, many painters use black cement to repair, and the effect is better than anti-rust paint!
Why do you want to prevent rust, first of all, the nail is to play a fixed role, if you don't do anti-rust nails for a long time, there will be rust, and there will be loosening after a long time, so that there will be keel, the ceiling will fall off, so it is not safe, even if it does not fall off the rust, there will be rust stains, it will also affect the appearance, for a long time, you have to waste money in the decoration, do a good job of rust prevention and use for a long time, and the post-maintenance treatment is also convenient. >>>More
