Putty powder construction three steps
For the general family's wall decoration, brushing powder opportunity is a necessary procedure. PuTTY powder can be painted white walls, and the wall surface is more evenly decorated. The wall surface of brushed putty powder is far smoother than the cement wall surface, and it can also cover wall cracks below 0.5 mm. Brushed putty powder wall, but also more convenient for further decoration, whether it is latex paint or wallpaper, are more solid! However, do you know how to putty powder construction? Xiaobian now takes you to see the construction steps!
First pass
Clean the wall surface (clean the wall peeling and cracks, and make up with cement mortar, shovel 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 primer should be prepared on the wall surface of cement plastering (pile, inverted) 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 the back-alkali wall is encountered, it can be sealed with caustic soda. After the caustic soda is dry, use anti-alkaline putty powder as the first layer, and then follow the normal steps.
5. Segregation: After the first pass, it will form an isolation layer, because the wall structure is very complex and there are many kinds of it now, such as returning alkali, returning yellow, local moisture and so on, 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 as a result of putty after construction, it is required to 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.
Second pass
Further leveling: After the first dry period, you can put on the second putty to further level off, the second time putty is not too thin, the putty paste water content should not be too large, to ensure that the second time putty water after shave As soon as the first pass is absorbed (slurry), the water can be calendered only after the water is reduced to a certain extent.
The third pass
The third and second pass were very short (2, 3, and 3), and the third pass was mainly calendered. The last part of putty construction, the surface effect of putty construction, was shown on the third pass. 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.
Putty powder construction precautions
1. When saving, pay attention to waterproof, moisture, storage period of six months.
2, the construction temperature above 0 °C, putty powder into a paste should be used within 4-5 hours to avoid prolonged deterioration.
3, putty powder and other putties can not be used in the same construction surface, so as not to cause chemical reactions and color, if the sound is different from hand to hand, with the outside temperature changes, slowly cracks, cracks along the empty drum direction Cracking. If you open the cracks, you will see that the putty and the bottom of the wall are two layers with a layer of dust in the middle. To solve this type of wall, first look at the wall base, such as severe powder removal, must be removed clean, rinse with water before you can putty putty, if not too serious, as long as the surface can be used after the glue roll brush can be full of putty.
4, the formula is irrational, generally in the design of the formula depends on the requirements of the project, the requirements are internal or external walls, rigid or flexible. No matter whether it is putty or thermal insulation mortar, there is a law: strength and flexibility are inversely proportional, the greater the strength, the worse the flexibility, the easier to crack, different strength and flexibility require different powder.
5, it is also a kind of adhesive, inevitably overflows when modulating with talcum powder, so the construction site will become paralyzed. If you decorate in the summer, the scene will be obvious. In addition, it is difficult for sodium cellulose to soak in the winter, so that the adhesion effect is greatly reduced. The raw materials of the putty powder are easily soluble in water, and can be used only by adding water and stirring.
In short, some experience in the construction of putty powder can only be expected and cannot be conveyed. The use of putty powder for the first time requires you to find your own feelings. When you encounter complex situations, you will find solutions to the unusual situation and gradually gain experience in construction. 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€. The above is related to the three steps of putty powder construction.
