Classification and difference of putty

1. What are the components of putty?

(1) Ordinary putty is mainly made of white powder, a little starch ether and CMC (hydroxymethyl cellulose). This kind of putty has no adhesion and is not water-resistant.

(2) Water-resistant putty paste is mainly composed of high-molecular organic matter, gray calcium powder, ultra-fine filler and water-retaining agent. This kind of putty has good whiteness, high bonding strength, water resistance, and is a rigid and alkaline product.

(3) Water-resistant putty powder is mainly composed of calcium carbonate, gray calcium powder, cement, Nok redispersible latex powder, water-retaining agent, etc. These products have high bonding strength and water resistance, and are rigid and alkaline products .

(4) Emulsion-type putty is mainly composed of polymer emulsion, ultra-fine filler and water-retaining agent. This type of putty has excellent water resistance and flexibility, and can be used on various substrates, but the price is high and it is neutral product.

2. How are the putties on the market classified?

(1) According to the state: paste putty, powder putty, glue with filler or cement.

(2) According to water resistance: water-resistant putty, non-water-resistant putty (such as 821 putty).

(3) According to the occasion of use: putty for interior walls and putty for exterior walls.

(4) According to the function: water-resistant putty, elastic putty, high-elastic waterproof putty.

3. What are the advantages of water-resistant putty?

Water-resistant putty is one of the best alternatives to ordinary putty.

(1) Strong adhesion, high bonding strength, certain toughness and good air permeability.

(2) There will be no pulverization after being exposed to moisture, and it has strong water resistance.

(3) When the water-resistant putty is used, the wall surface will not crack, peel, or fall off.

(4) The wall surface using water-resistant putty has a delicate hand feel, a soft look and feel, and a good texture.

(5) After the wall surface is polluted with water-resistant putty, it can be directly scrubbed or brushed with interior wall paint. And can improve the performance and service life of the coating.

(6) When repainting the interior wall, it is not necessary to remove the wall surface, but directly paint the interior wall paint.

(7) Water-resistant putty is an environmentally friendly material that does not cause any pollution to indoor air.

4. What are the disadvantages of ordinary putty?

(1) The adhesion is poor and the bonding strength is low. In order to overcome this defect, some high-quality home improvement companies apply an interface agent on the base. Increase costs and increase man-hours.

(2) No toughness.

(3) Pulverization will appear soon after encountering moisture.

(4) Cracking, peeling, peeling and other phenomena appear in a short period of time. Especially for the treatment on the moisturizing board of the inner wall, it is difficult to eliminate the above phenomenon even if it is fully sealed with cloth. After the construction is completed, it will bring multiple repairs, which will cause inconvenience to users.

(5) When repainting the wall, the original 821 putty needs to be eradicated, which is laborious and pollutes the environment.

(6) The surface is not delicate enough and the texture is poor.

5. In comparison, what are the advantages of putty powder?

Putty powder is a mixture of polymer powder and powdery glue. After mixing with water in a certain proportion, it can be used to level the wall. Since formaldehyde can only exist in gaseous or liquid form, comparatively speaking, the formaldehyde content in putty powder is the least or even non-existent, which is more environmentally friendly.
