Excluding fake and shoddy, the putty is scraped thick (putty is the rough surface of its leveling concrete, which has little to do with thickness, not to say that the thicker the better, the key is to level off), and the putty is dry, which is also a very important factor and a construction problem! Paint is only a semi-finished product, and construction is also a very important link. If good paint is made by parallel workers, the products will be unbearable.

It is best to use a roller brush, so that the paint film is thicker and the wear resistance is better.

The addition of water should not exceed 20%,

Most domestic painters like to add water to the paint and brush it with wool. The effect is smooth and smooth, but! This construction method must add 40-60% water before construction, otherwise the brush will be uneven and the first brush mark will appear!

The finished paint film is very thin and can't be scrubbed!

As for the gypsum board with a little strength, the putty is not strong enough (it is not easy to polish if it is added too much)

What's more, I suggest that you don't save money on primer (professional sealing primer or alkali-resistant primer, not parallel topcoat), because primer is a very important link.
