Spring is the peak season for decoration. When using putty powder for wall treatment, due to the particularity of spring climate, it is necessary to pay attention to some details to ensure the decoration effect and quality. Here are some practical tips for using putty powder in spring decoration:

1、 Storage precautions

1. Moisture proof storage: in spring, the air humidity is relatively high, so the putty powder should be stored in a dry and ventilated place to avoid being directly stacked on the ground, and it is best to pad it up with wooden boards to prevent the erosion of moisture on the ground. At the same time, the package shall be sealed to prevent moisture from entering and affecting the performance of putty powder.

2. Avoid exposure to the sun: the putty powder cannot be stored in a place with direct sunlight, otherwise it may cause the putty powder to agglomerate and deteriorate in advance. Choose a cool storage environment.

2、 Preparation before construction

1. Wall base treatment: thoroughly clean the wall, remove dust, oil, loose objects, etc., to ensure that the wall is solid and flat. For the newly built wall, it is necessary to wait for it to be fully dry. Generally, it needs a curing period of about 28 days to ensure the stability of the wall.

2. Detection of wall humidity: use a humidity detector to detect the moisture content of the wall, which should be less than 10%. If the humidity on the wall is high, dehumidification treatment is required, such as ventilation, use of dehumidifier, etc., otherwise the adhesion of putty powder will be affected, resulting in peeling, peeling and other problems in the future.

3. Accurate mixing proportion: the putty shall be mixed in strict accordance with the proportion in the putty powder product manual. The amount of water added shall be accurate and the mixing shall be sufficient and uniform to avoid the situation that the putty is too thin or too thick. The too thin putty is not strong enough after drying, and the too thick putty is difficult to scrape.

3、 Key points of construction process

1. Control the construction ambient temperature: the temperature changes greatly in spring, and the ambient temperature for putty powder construction should generally be above 5 ℃. Low temperature will affect the drying speed and curing effect of putty powder, resulting in insufficient strength of putty powder.

2. Thin and multi-layer: the puttying shall follow the principle of "thin and multi-layer", and the thickness of each puttying shall not exceed 2mm, so as to avoid cracking of the puttying layer caused by excessive thickness of one-time puttying. Generally, the putty is applied for 2-3 times, with an interval of 1-2 days. The specific time depends on the weather conditions and the degree of dryness of the putty.

3. Pay attention to ventilation time: proper ventilation shall be maintained during construction, but excessive ventilation is not recommended. It is windy in spring, and strong wind will make the water on the putty surface evaporate rapidly, resulting in dry cracks on the surface. You can choose to ventilate when the wind speed is low in the morning and evening, or adopt intermittent ventilation.

4、 Post construction maintenance

1. Wait for natural drying: after the putty is scraped, let it dry naturally. Avoid using heating equipment to accelerate drying, so as to avoid inconsistent drying speed inside and outside the putty layer and cracks.

2. Avoid premature polishing: the putty needs to be polished after drying. Generally, it is appropriate to polish it 3-5 days after the batch scraping is completed. The specific time depends on the actual drying situation. If the putty is polished too early, the strength of the putty is not enough, and it is easy to polish too much, which will affect the flatness of the wall; If the putty is polished too late, the hardness of the putty will increase and the grinding difficulty will increase.

3. Prevent the wall from moisture: in the subsequent decoration process, such as the installation of doors and windows, water and electricity transformation, attention should be paid to the protection of the wall to prevent water splashing on the wall, causing the putty layer to become damp and moldy.

Following the above tips on the use of putty powder for spring decoration can effectively improve the construction quality of putty powder and create a more beautiful and durable wall effect.
