What is the production method of gypsum and how to color it?

Gypsum will be used in many interior decoration, because gypsum has strong plasticity. Next, Bian Xiao will tell you how to make gypsum and how to color it.

1. What is the production method of gypsum?

1, bottom material. Animal hide glue or water glue 70-100g, water1l. Apply it two or three times. You must wait until the glue is completely dry before applying the next few layers.

2. Primer. Glue solution, zinc white and gypsum each 1 serving. One layer should be as Bo Tu as possible, such as a layer of yarn. Doing so will help each layer to obtain strong adhesion in the future. The coating direction of the second layer should cross the same layer. A layer of stuffy after half an hour, the same can't be painted too thick. And so on for the third and subsequent layers until the roots are smooth, bright and white, and no wood grain can be exposed anywhere. Generally, 5 ~ 6 floors are needed.

3. Gypsum root must be painted several times. It's normal to paint eight to ten layers. Although only one or two layers of roots can be used, they may fall off or crack after drilling. Because you don't have to wait for the first coat to be completely boring, you can apply the next coat, so it is very convenient to complete the production of gypsum root in one morning. Do not dry quickly in the sun or on the heater to avoid the color layer falling off in the future.

Second, how to color gypsum

1. Gypsum roots are made of hard supporting materials. Many painters are used to sticking a layer of gauze or other cloth on the bottom plate first, which can not only make the coating more firmly combined with the bottom plate, but also make the board feel useful because of a layer of gauze. Available fabrics are: linen, white cloth, packaging cloth, gauze and so on.

2. Coloring on gypsum roots may cause oil absorption, which is a good phenomenon in a sense, because it means that oil and roots really blend together. If oil-free root piles are needed, a thin layer of polishing oil or glue can be coated on the gypsum root piles.

The above is the production method and coloring method of gypsum. Everyone learned to design some plaster decorations by themselves, which is very novel! I hope the above content will be helpful to everyone.
