content briefly: construction, coating when coating mixture ratio, primary wall when handled properly, will encounter some common quality problems, you can read this article about the cause of these quality problems and treatment methods. Coating construction usually will encounter these problems, you can handle, Including the construction technology)

coating construction, when coating mixture ratio, primary wall when handled properly, will encounter some common quality problems, you can read through this article to understand the cause of these quality problems and treatment methods.

coating construction technology

, metope smooth, dry, There are more than days curing period) , no dust, grease and oil, such as asphalt base of PH & lt; , moisture content & lt; %, and inspect the whole metope, are free drum phenomenon, and repair of the porous, rough surface with grinding to ensure metope whole effect.

, be bored with child construction: after being wall surface processing of qualified, Shanghai, use special be bored with child number two, putty scraping request uniform smooth, dry grinding.

and elastic special primer construction: stay after completion of the above work, the TER - D - Elastic special primer for construction, roller coating, first part use row brush to brush again, prevent leakage brush, enhance the wall and surface coating bond strength and waterproof function, primer dosage about. Kg/m。

and elastic middle paint construction: after waiting for primer is dry, ℃ / hour) , the TER - C - Middle paint during the construction. With roller first roll equably on aggregate in metope, reoccupy special garland roller construction a uniform pattern, decorative pattern is not very uniform, if rolls out roll can be more than a few times until evenly, to ensure the fine flowers. But the construction time shoulds not be too long, otherwise pull out the pattern due to the dry degree of aggregate affect the uniformity of texture. The coated dosage about. Kg/ m。

and elastic latex paint construction: after waiting for paint dry in garland ( ℃ / hour) , the TER - C - Multi-function elastic latex paint for the construction, the construction is made of high quality wool roller roller coating, coating uniformity, prevent roller mark. Dosage of surface besmear two roller coating, surface coating. Kg/m。

and jointing finishing construction: at the end of the construction, on the metope of non-performing timely repair, to tick off seam line, jointing asked straight uniform, ensure metope whole is beautiful.

and cleaning up, avoid the pollution of metope.
　　
　　常见涂料施工质量通病及处理方法
　　
　　一、粉化现象
　　
　　原因：
　　
　　、基层有粉层、油污等
　　
　　、涂刷时温度低、成膜不好
　　
　　、涂刷渗水太多
　　
　　、涂刷耐侯性差
　　
　　、墙体表面未加以处理
　　
　　处理方法：
　　
　　、上漆前应将表面松脱的旧面漆、尘埃、油污清除
　　
　　、施工温度应保持在摄氏度以上
　　
　　、减少渗水量
　　
　　、涂上二层耐候性好的面漆
　　
　　二、流挂现象
　　
　　原因：
　　
　　、漆膜厚度一涂得过厚
　　
　　、涂刷时加水太多
　　
　　、环境湿度过大
　　
　　、下层漆没有打磨，附着差
　　
　　处理方法：
　　
　　、多涂几漆，不宜一涂完
　　
　　、减少渗水量
　　
　　、减少环境湿度，避免在环境湿度过大的天气施工
　　
　　、打磨被涂物表面
　　
　　三、变色发花或泛青现象
　　
　　原因：
　　
　　、基层含水率过大
　　
　　、基层碱性过大
　　
　　、施工环境有化学气体发生
　　
　　处理办法：
　　
　　、让基层完全风干
　　
　　、水泥基层干燥要养护一段时间
　　
　　、严禁与聚氨脂类涂料同时施工，若已使用可先用砂纸将墙面轻打磨，再上底漆与面漆。

4, chromatic aberration disease prevention measures

, engineering batch purchasing raw materials, to send to factory inspection materials enter the construction site for recheck, construction before inspection, to ensure that the colour and lustre is consistent, prevent color difference;

, in strict accordance with the construction requirements for raw material before construction of uniform mixing, the specialist is responsible for the uniform mixing of materials to the timely spraying;

, in sealing primer before construction, to level off the wall surface;

, strictly control the construction process, different color coating and spraying is prohibited.

5, the technical methods of sensory effects

and keep spraying and coating consistency degree of constant pressure, wind speed over & ndash; % s, stop spraying construction;

, finished product before construction strictly control the coating, the surface coating to continuous uninterrupted construction;

, maintain appropriate spraying distance, maintain appropriate coating consistency;

and the wind under construction, not every time don't too thick coating thickness.
