4. Water-resistant putty is too dry and fast, and its moisturizing time is too short to reach the normal bonding strength.
預(yù)防：1、選用360#--600#砂紙砂磨.。
Prevention: 1. Choose 360 # - 600 # sandpaper grinding.
2、膩?zhàn)臃峙鋾r(shí)只需加水.。
2. When putty is distributed, only water is needed.
3、砂磨時(shí),膩?zhàn)討?yīng)干到八成以上。
3. When sanding, putty should be dried up to more than 80%.
4、施工時(shí)應(yīng)依據(jù)環(huán)境氣候適度控制膩?zhàn)拥目菰飼r(shí)間。
4. The dry time of putty should be moderately controlled according to the environment and climate during construction.
整改：用較細(xì)砂紙修磨或上過(guò)底漆后用底漆配滑石粉刮補(bǔ)。
Rectification: grinding with fine sandpaper or scraping with primer and talc powder.
顏色不一
Different colors
現(xiàn)象：膩?zhàn)邮┕ず螅獗碛猩罨蛏摺?/div>
Phenomenon: After putty construction, there are color differences or spots on the surface.
緣由：1、運(yùn)用了不同型號(hào)或批次的產(chǎn)品會(huì)有細(xì)微色差。
Reasons: 1. Products of different models or batches will have slight color difference.
2、基層未處置好，滲色。
2. The grass-roots units are not disposed of properly and seepage.
3、膩?zhàn)又谢烊肫渌镔|(zhì)，配比或攪拌不平均。
3. Putty mixed with other substances, the mixing ratio or stirring is uneven.
4、被污染，如噴漆，滲水，油煙等。
4. Contaminated, such as spray paint, water seepage, soot, etc.
預(yù)防：1、壓光膩?zhàn)颖韺討?yīng)選用同型號(hào)同批次產(chǎn)品。
Prevention: 1. Calendering putty surface should choose the same model and batch products.
2、對(duì)基層污漬必需肅清或封鎖處置，接縫王要待干透后刷耐黃變封鎖底漆。暴露金屬要做防銹處置。
2. The base stains must be cleaned up or blocked. The seam king should brush the yellowing resistant blocking primer after drying out. Exposure to metal should be treated with rust prevention.
3、施工時(shí)要留意現(xiàn)場(chǎng)防護(hù)。
3. Attention should be paid to site protection during construction.
整改：1. 膩?zhàn)淤Y料色差上過(guò)涂料后即可消弭。
Correction: 1. Putty material color difference can be eliminated after coating.
2. 污染性色差需肅清污染源并對(duì)受污染基層做封鎖處置。
2. Pollutant color difference needs to be cleaned up and blocked at the polluted grass-roots level.
