Anonymous users2024-01-24Self-tapping screws are treated with anti-rust paint, and nail caps are used conventionally. If you spray anti-rust paint by hand, it will be better than the point.
It is best to do anti-rust treatment, otherwise rust will appear after the batch of putty is soaked in water, and the white will turn yellow to expose traces.
After a long time, there will be problems, because gypsum board is quite heavy, nails alone are far from enough, some gypsum board ceilings also have to be painted with white latex, and nails alone are the easiest to crack, but generally can't fall down, hehe.
Gypsum board ceiling with self-tapping screws is better than using wooden gun nails.
Re-replaced, gypsum board ceiling with drywall nails, so that the light steel keel can be used to clamp the light steel keel, which is also a special screw for gypsum board ceiling, you use self-tapping screws are not in line with the specification.
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
