Do gypsum screws need to be rust-proofed?

Whether the self-tapping screws of gypsum board ceiling need to be painted with anti-rust paint depends on the type of screws and construction habits.

● Self-tapping screws that have undergone the blackening process do not need to be painted with additional anti-rust paint, because this type of screw already has anti-rust function.

● For other types of self-tapping screws, although it is not necessary, it is customary to carry out anti-rust treatment to protect the metal surface from chemical or electrochemical corrosion of the atmosphere, seawater, etc.

● Anti-rust paint is a coating that can protect the metal surface from chemical or electrochemical corrosion of the atmosphere, seawater, etc., and can provide better protection by applying two coats of anti-rust paint.

● During the decoration process, it is very important to carry out anti-rust treatment on gypsum board screws, which can not only prevent the screws from rusting, but also ensure that the paint is full and leak-free, ensuring that the screws will not rust in the later stage, thereby avoiding the yellowing of white walls due to rust, affecting the living experience and the aesthetics of the overall space.
