What are the painting steps for room decoration?

First, the preparation work before construction

1, the wall should be kept dry, the surface moisture should be less than 6%, the PH value should be less than 9, and the new cement construction should generally be maintained for 20 to 40 days.

2. Before construction, protrusions should be removed, and oil, dust, alkali, mold and loose layers should be removed. In addition, it can be washed with dilute acid, washed with clear water, dried and then coated; When ripping, first remove the mold on the construction surface with a shovel, and then spray it twice with wall washing water. Paint can be applied after drying.

3. During construction, a small amount of water can be added or diluted according to the climatic conditions and specific painting conditions (see the instruction manual of each variety for specific addition amount). When the temperature is lower than 7℃ and the humidity is higher than 85%, it is not suitable for construction.

4. Don't use polyester paint when painting the wall paint, because the free TDI will make the paint yellow.

5. In order to make the paint film durable, color-preserving, and free of alkaline substances in the wall, a sealing primer should be used for priming.

Second, the interior wall coating construction process

1, remove dust and dirt on the surface of wood products and lines (wood base).

2. Trim the burr, splitting and other defects on the surface of wood base, and polish with sand skin to make the edges and corners neat.

3, with oily putty (or transparent putty) batch scraping, grinding, polishing after filling putty (with varnish, brown eye and nail eye first, and do a good job of local color modification).

4. Brush the paint for the first time, repair the putty, and remove the surface dust after polishing.

5. Brush the paint for the second time, remove the surface dust after polishing, and polish it with water sand skin.

Third, the order of painting the wall

1. Draw the ceiling first, starting from the nearest place to the natural light source and gradually moving away.

2. Secondly, paint the wall from top to bottom, with a width of about two feet each time, starting from the natural light source and then gradually moving away.

3. Then, paint the window, starting from the side of the window and ending with the edge of the window frame.

4. Next, draw details, such as the mosaic at the junction of the wall and ceiling.

5. Finally brush the skirting board.

Standard structure

Putty 1 coating+back cover 1 coating+topcoat 2 coating;

Excellent construction: 2 layers of putty+1 layer of sealing primer +3 layers of paint.

I will introduce you to the basic skills of how to paint the wall. See www.degeshi.com for detailed steps.

1, when the paint reaches the stressed edge of the wall, in order not to make the paint cross the boundary, you can use a ruler or cardboard as an auxiliary tool to press against the boundary and follow the brush to achieve a neat effect.

2. When drawing the arc area, frame the arc curve with torn tape, so that the curve can be drawn beautifully.

3. When the wall is painted vertically, it is about two feet wide at a time, but it is painted horizontally from time to time.

4. After all the paintings are finished, the yellow paint is slightly dipped with a brush to brush the wall to eliminate all the straight lines.
