First, the wall is old and the skills to deal with wet walls?

1, wall aging and skills to deal with wet walls-old walls with retro paint. Pave the cement wall first, then dry it to form a natural wall with a roller brush, and do the old texture.

2, the wall is old and the skills to deal with wet walls-the wall with wallpaper. Such a wet wall will make the wallpaper become warped, deformed and discolored. It is recommended to change the wallpaper of the whole wall. The color difference between the old wallpaper and the new wallpaper is obvious. The wallpaper has been used for too long, and there may be no wallpaper with color. The same color may also have color difference, so the owner had better buy more wallpaper to avoid the wall from being damp.

3, the wall is old and the skill of dealing with the damp wall-latex paint wall. Latex paint walls are prone to empty drum, powder dropping and mildew spots. When we deal with it, we should first scrape out the wet place with a shovel, then scrape putty, brush primer and paint. When repainting latex paint, we should strictly follow the construction methods and requirements of latex paint. In order to avoid the color difference of the wall, you can only repaint the colored wall on the whole wall. If it is a white wall, you can handle the wet position.

4, the wall is old and the skills to deal with the damp wall-bathroom wall. Toilets leak most easily. Now the ceiling of the bathroom generally adopts aluminum gusset plate, so don't worry. The light steel keel of the ceiling is generally 0.8cm, and the light steel keel material purchased through formal channels is not easy to be corroded. The tiles on the bathroom wall change color, darken or even turn black after being wetted. The color of ceramic tiles will become darker after being wetted, but it will not change color. It should be a visual error that the ceramic tile turns black when it is wet, and it will return to its original color after drying.

Second, the wall painting solution?

1, paint peeling: It may be because the surface is too smooth. If the original paint is shiny or powdery (with untreated paste paint), the new paint will not stick to the surface firmly. It is also possible that the wood is rotten or the metal is rusted, and it is also possible that the poor quality of the paint causes peeling. Small areas of paint can be polished with spun paper, then putty, primer and repainting. If there is a large area peeling off, all the paint must be peeled off and repainted.

2, paint foaming: first puncture the bubble, if there is water, it means that there is water infiltration under or behind the paint layer. After sun exposure, the water evaporates into steam, which will jack up the paint skin into bubbles. At this point, first remove the initial paint with a hot air spray gun, let the wood dry naturally, then brush the primer, and finally repaint the whole repair surface. If there is no water in the bubble, it may be that the wood grain is cracked and there is a small amount of air inside. After the sun shines, the air expands and the paint skin bulges. Faced with this situation, first scrape off the blistered paint skin, then fill the gap with resin filler and repaint it, or directly apply microporous paint without filler.

3, paint flowing: paint is brushed too thick at a time, which will cause flowing. Brush off the paint before it is dry. If the paint surface has begun to dry, let it dry completely, smooth the paint surface with spun yarn paper, brush the surface clean, then wipe it clean with a wet cloth, and then reapply the outer paint. Be careful not to brush it too thick.
