2. If you want to brush a colored room, you can directly buy colored latex paint. If you change it, you must finish it once, otherwise there is a color difference.
3, roller brush quality must be better, the length of the wool is moderate, uniform density, which affects the effect of painting.
4, first brush the ceiling, then brush the walls.
5, must be the first time to dry the brush again.

First, roughcast room metope has been scraped putty, and commonly known as the four white ground, still need to brush metope paint.
Two, the steps of painting the wall of the roughcast room:
Step 1: Overhaul.
Thoroughly check whether the cement wall in the roughcast room that needs to be painted is solid and smooth.
If the plaster layer of the wall is not strong enough or there are big cracks and holes, it is recommended to complain to the developer or the property, and ask it to redo.
If individual holes are repaired by themselves, plaster can be used to fill them.
Powder coating powder manufacturer can supply related coating powder.
Step two: Finished product protection.
processing metope can have dust, and hard to be avoided can have be bored with child, powder coating or other glue drops, must do well in advance to already decorate the protective work of finished product inside the room so.
Step three: the preparation before scraping putty.
Ensure that the wall is solid and smooth. Clean the wall with a steel brush or other tools to make the cement wall as far as possible without floating soil, floating and sinking.
In METOPe roll a concrete interface agent, as far as possible uniform, after waiting for ITS dry (generally in more than 2 hours), can scrape putty.
Step four: scraping putty (please choose water resistant putty).
Before scraping putty, the flatness of the wall should be measured (with 2m or more inspection ruler) to determine the method of scraping putty.
general metope is scraped 2 be bored with child can, can make flat already, can cover the background color again.
The putty with poorer flatness needs to be scraped a few times more locally.
If the flatness is very poor, the wall tilt is serious, you can consider scraping the plaster for leveling, and then scraping the putty.
The interval time for each batch of putty scraping should be more than 2 hours (after the table is dry).
Step five: Polish putty.
After the water resistant putty is fully strengthened (5-7 days), it will become very solid, at which point it will become extremely difficult to sand.
Therefore, it is recommended to start polishing putty 1-2 days after scraping the putty.
Grinding can be optional at night, with 200 watts above the bulb close to metope lighting, polishing side to check the level.
Step 6: Apply primer.
After CLEANING AND polishing the putty surface of the floating dust, can besmear brush primer.
Primer can be painted once, be sure to be uniform, after it dry (2-4 hours) can be the next step.
Step seven: Brush the finish paint.
The top paint is usually brushed twice, and each time should be separated by more than 2-4 hours (depending on its dry time) to be basically dry.
after the second time face paint is brushed, need 1-2 days to be able to completely dry, before powder coating completely dry should pay attention to waterproof, drought prevention, sunscreen, prevent paint film problems.
Step eight: Acceptance.
The surviving wall should be solid, smooth, Yin and Yang vertical, no cracks, no holes, uniform color, full paint film, and pay attention to checking the protection of finished products.
