CALCIUM CARBONATE FOR PUTTY WALL APPLICATION 

Putty in the paint is used to fill the base surface, is the middle layer of the overall coating, no matter what putty needs to add a lot of filler. In the various types of latex paint, the external wall products and matching putty used in the main heavy calcium carbonate, a small amount of some zinc barium to increase the viscosity to prevent the paint layer lose, while appropriate to add light calcium carbonate to dry After grinding.

Putty wall’s main function

Putty wall’s main function is to flatten the wall surface before applying the finishing layer to have a flat and beautiful wall surface. The basic ingredients of wall putty include: Binder + Filler + Additives

* Binder: Includes 2 types of mineral binders (usually Cement or Gypsum) and polymers binders.

* Filler: Used to enhance some activity, increase firmness, workability, flow resistance, and increase volume. The commonly used filler is stone powder - Calcium Carbonate Powder (CaCO3) which accounts for about 60% of the content in the production of wall putty...

* Additives: A material that accounts for a very small part of the composition but plays a very important role: giving the product some necessary properties, keeping water for the setting time, making it easy to apply, increasing application time, improving curing properties, and curing time.

 

Calcium carbonate for wall putty application

Calcium carbonate filler composition in the practical operation of putty powder:

1. Cracking problem

Calcium carbonate filler size can not be too fine, high fineness of calcium carbonate filler requires more adhesive to bond, but also cause greater drying shrinkage. After a short period of time without coating paint, putty film will appear subtle cracks. The following are the same as the ones

2. Smooth problem

Calcium carbonate filler fineness is too thick, will lead to putty rough, the wall is not smooth. Calcium carbonate filler fineness to be appropriate, generally controlled at 250-300 head or so. The following are the same as the ones,

3. Sticky problem

The amount of light calcium carbonate over the General Assembly will cause the putty is too thick, this time should be reduced or not light calcium carbonate.

4. Coating gloss problem

The higher the amount of light calcium carbonate, the higher the gloss of the coating. Factors that adversely affect the gloss of the coating, such as the improper use of the constituent materials, should increase the amount of base or light calcium carbonate.
