What should I pay attention to when scraping the interior decoration?

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. The detection method is hand-touching, and there is no humidity. I can't see the watermark.

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 (summer, rainy season in the south and winter.

Extended data:

The walls are scratched white, and the doors and windows (door and window decoration renderings) are not easy to open. If the indoor air is too pungent, you can turn it on properly instead of turning it on frequently. When debugging Dabai material, the proportion of gypsum powder must be increased to enhance the adhesion of Dabai and prevent cracking.

The wall putty can't be scraped too thick, because the indoor air is dry and loses water quickly, which is easy to cause empty drum, crack and uneven wall. In addition, the wall putty can not be dried by temperature, but only by wind, so the putty must be scraped very thin and can be scraped several times. The putty on the wall will crack when it is dry, which reduces the trouble of repeated maintenance in the future.
