One. Can putty powder be used to fill gaps?
No.
Putty is putty, and joint filler is joint filler.
Putty is a primary material used to repair and level walls, providing a solid foundation for subsequent decoration (painting and wallpapering). Putty is typically made from gypsum or cement, which creates a rough surface that allows for strong adhesion. However, it is still necessary to apply an interface treatment agent to the substrate before applying the putty to seal the substrate and improve the adhesion of the putty to the wall.
Putty powder lacks elasticity and extensibility, making it unsuitable for joint filling. When filling joints, it is necessary to use specialized jointing materials. It is also important to note that other materials, such as commercially available joint fillers, self-leveling joint fillers, and adhesive joint fillers, should not be added to the putty powder to adjust its consistency. These materials have different types and compositions, and it is essential to select materials that are compatible with the tiles.
Two. The difference between putty powder and joint sealant.
1、What are the properties and performance of putty powder?
Putty powder is a type of building decorative material, primarily composed of talc powder and adhesive. Putty is divided into interior and exterior types. Exterior putty must resist wind and sun, so it has high adhesion and strength, and a slightly lower environmental rating. Interior putty has a good overall performance, is healthy and environmentally friendly, so it is used only for interior walls, and exterior walls should not be used for interior purposes.
The advantages of putty powder include its unique whiteness and density, strong adhesion, and high bonding strength. It does not exhibit a powdery appearance after being exposed to moisture and possesses good water resistance. The surface finish achieved with putty powder is smooth and delicate, with a soft and pleasant texture. After applying a finishing coat, the surface feels smooth and provides a good tactile experience. It can be used as a finishing layer in construction projects.
The disadvantages of putty powder include: it is more difficult to apply and finish; and it is alkaline before it dries completely.
2、What are the properties and benefits of joint fillers?
Joint filler is used in the gaps between tiles to achieve a better tile laying effect, while also preventing dirt and debris from accumulating. It can be used to bond and fill gaps between various products such as ceramic tiles, stone, glass, mosaics, crystal stone, imitation bricks, cement, concrete, wood, and metal, as well as for waterproofing and sealing.
The advantages of the joint filler include high hardness, excellent brightness, no shrinkage, no mold growth, strong adhesion to walls, resistance to acids and alkalis, excellent stain resistance, and ease of use, with the ability to be cleaned directly with water.
One disadvantage of the joint sealant is that it can be difficult to achieve a smooth finish. Additionally, when tiles are not perfectly level and experience seasonal expansion and contraction, the joint sealant and the tile joint can be prone to cracking, manifesting as peeling and detachment of the sealant.
3. Distinguish between putty powder and joint sealant.
The primary difference between putty powder and joint filler is their intended use. Putty powder is used for repairing and leveling walls, while joint filler is used for bonding and filling gaps between tiles or stone on floors. The specifications and properties of these two products are significantly different.
