The application of the paint-free latex paint waterproof putty powder is divided into three passes. The worker's technique is not necessarily the same during the specific construction. After careful observation and careful analysis and summarization, the following construction methods and principles are summarized for reference during construction.
The first time <br>clean up the wall surface (clean the wall peeling and cracks, make up with cement mortar, shovel the residual ash clean, then sweep the wall)
Adhesion: Let the putty and the wall be well bonded to lay a solid foundation for the next step.
1. Leveling: Make the construction wall smoother.
2. Three parts of putty powder and seven parts of gypsum powder (optimum modified gypsum) can be used as special repair materials for the wall (instead of traditional plaster repair methods).
3. The base material should be prepared on cement wall surface (pile and inverted wool) walls, so that the project cost can be reduced and the construction quality can also be improved. Bottom material preparation method: use high black cement 100 kg plus 40 kg indoor putty powder mix more evenly, then add to the container and stir with water after stirring.
4. If you encounter a back-alkali wall, you can use alkaline water to seal it. After the alkali-free water is dry, use anti-alkaline putty powder as the first layer, and then follow the normal steps.
5. Segregation: After the first pass, the isolation layer can be formed, because the wall structure is very complex and there are many kinds of it now, such as returning alkali, returning yellow, local moisture, etc., which need to be made according to different situations. Corresponding treatment measures.
6, so that the next step water absorption: the construction of the wall material is not very uniform, especially the old wall, then the water absorption is different, to achieve the shiny after construction of putty, such as glass, it is required that the putty in the light when the humidity should be the same, so The light and hardness of the press will be uniform, otherwise it will appear bright, and it will not shine.
In short, the first pass has a great effect, we must pay special attention to: must be dry, the more dry the better, due to dry out to achieve the above effect. The dry time for the first pass is normally 24 hours, but the specific time varies depending on the condition of the wall and the weather conditions.

The second time <br> further leveling: After the first dry time, you can put on the second time putty to further level, the second time putty is not easy to thin, putty water content should not be too large, to ensure that the second time putty The water after the squeegeeing is absorbed by the first putty as soon as possible, and the calendering can be performed only after the water is reduced to a certain degree.
The third pass <br>The third and the second pass are very short (secondary and third), and the third pass is mainly calendered, making the last part of putty construction, the surface effect of putty construction is in the third All over again. After the second pass of the squeegee, the slurry was slightly squeezed, followed by a third stroke, and then the calendering was started to achieve a bright and sturdy effect. Both light and strength coexist.
In short, the construction experience of putty powder is somewhat thankful. The first time use putty powder construction requires you to find your own feelings. When you encounter complicated conditions, you will find ways to solve the problem, and you will gradually accumulate construction experience. It has been found that many large-scale workers have neglected putty powder construction and have not achieved the best results after construction. It should be the attitude of “defeating it strategically and valuing it tacticallyâ€.
