One、Difference between putty powder and white powder
1、Different compositions
Fine white powder: Composition consists of calcium carbonate.
Putty powder: Formulated with a small amount of paint, additives, a large amount of fillers, and a small amount of coloring pigments.
2. Different functions
Large-particle cement: Used for covering walls and ceilings to prevent cracking and detachment. A layer of interface treatment agent should be applied to the substrate before application.
Putty powder: Can be used to fill localized depressions on the working surface, or applied to the entire surface after removing any existing coatings. Typically applied to the surface of the primer coat after the primer has fully dried. Requires good adhesion and should not crack during baking.
3. Different characteristics
Fine white powder: Poor water resistance, good solubility, and high gloss.
Putty powder: Requires more effort for application and sanding; some products may have alkaline properties before complete drying; certain putty powders exhibit water resistance.
4、Using different
Putty powder: Add water directly when using.
Fine powder: Requires the addition of adhesive when used.
Two, which is whiter: putty powder or white cement powder?
Putty is a base material used for repairing and leveling walls, providing a solid foundation for subsequent decoration (painting and wallpapering). Putty is available in two types: interior and exterior. Exterior putty is designed to withstand wind and sun exposure, so it has high adhesion and strength, but a slightly lower environmental rating. Interior putty has a good overall performance, is healthy and environmentally friendly, so it should only be used for interior walls, and not exterior walls.
"Daba Powder," also known as "Double-Flying Powder," is a calcium carbonate-based material commonly used for leveling walls in home renovations. Typically, Daba Powder is mixed with cellulose, PVA (polyvinyl acetate), and water to create a viscous paste, which is then applied to walls and ceilings. To prevent cracking and detachment, an interface treatment agent should be applied to the underlying substrate.
If we consider the color only, the white powder is slightly whiter.
Note: Putty powder and white cement can both be used as the base material for wall decoration, providing a foundation for subsequent decoration. Therefore, the primary focus of this comparison is between these two options.
