What is putty powder made of? What is putty powder and how to use putty powder

Putty powder is a kind of building decoration material, and the main ingredient is talcum powder.

and glue. Putty is generally composed of base material, filler, water and additives.

1) The base material, also known as the binder, is the most critical component of putty, which mainly plays various roles such as bonding. The most commonly used binders for putty are cement and organic polymers, which are divided into emulsions and latex powders. Cement is a binder with good cohesiveness, durability and reasonable cost performance, but tensile strength.

and poor crack resistance. Organic polymers can be modified and toughened to improve putty performance.

2) The filler mainly plays the role of filling, and calcium carbonate is commonly used.

talc and quartz sand.

Wait. Attention should be paid to the combination of packing fineness.

3) Additives include thickeners, water retention agents, etc. Thickeners and water-retaining agents play the role of water retention, improve storage and construction performance, and cellulose is generally used. Antifreeze is mainly used to improve the storage stability of putty at low temperature, and slip agents and water reducers are generally used in high-grade putty to improve the construction performance of putty.

How to use putty powder? Let's take a look at the specific steps.

Putty powder is a kind of building decoration material, and the main components are talcum powder and glue. A layer of white on the surface of the newly purchased rough house - putty, usually the whiteness of putty is above 90 and the fineness is above 330.

Putty is a substrate used for wall repair and leveling, which lays a good foundation for the next step of decoration (painting and wallpaper). Putty is divided into two types: interior wall and exterior wall, and the exterior wall putty should resist wind and sun, so it has high gelatinity, high strength, and slightly lower environmental protection index. The comprehensive index of interior wall putty is good, healthy and environmentally friendly, so the interior wall is not used externally, and the exterior wall is not used internally.

Usually putty is gypsum or cement-based, so that the surface is rough and it is easier to bond firmly. However, during construction, it is still necessary to apply a layer of interface agent on the base layer to seal the base layer and improve the adhesion of the wall, so that the putty can be better bonded to the base surface.

You can take a look at this article on what putty powder is.

It is formulated with a small amount of lacquer base, a large amount of filler and an appropriate amount of coloring pigment.

1. The pigments used are mainly iron red, carbon black, chrome yellow, etc., and the fillers are mainly bicarbonate key calcium, slippery stone powder, etc., which can fill the local sunken working surface, and can also be scraped off on all surfaces, usually after the primer layer is dry, applied to the surface of the primer layer, requiring good adhesion and no cracks during the baking process.

2. Water-resistant putty: one ton of calcium carbonate, ten kilograms of sodium carboxymethyl cellulose, eight kilograms of pregelatinized starch in Tongye, put it in a mixer and stir for 10 to 15 minutes.

3. Water-resistant putty for interior walls: heavy calcium or talcum powder, lime powder, and an appropriate amount of cellulose are mixed.

4. Water-resistant putty for exterior walls: stone powder, gray calcium, cement, cellulose, etc.

Shijiazhuang Yellow Cat Building Materials Science and Technology ****, heavy calcium powder (double fly powder or large white powder can be) 1 ton.
