First, the main construction equipment of the putty tool
1, the main equipment: putty mixer.
2, the main tools: putty scraper, 38 mm and 63 mm wide paint blade, putty plate, brown brush, hard plastic bucket, yin and yang angle.
3. The horn scraper is made of water ox horn, which is wide and thin, and has a certain slope to improve elasticity. Slowly narrow and thick upwards, the whole is smooth, and when the head is in a circular arc shape, the thumb and the other four fingers are divided into two sides of the scraper, so that the scraper is sandwiched between the thumb and the index finger. When filling holes, holes, cracks and putty, only 1 or 2 rounds are allowed to be scraped. First, scrape down and then scrape upwards. The putty in the hole and hole is completely covered.
When scraping the putty, use the thumb and the other four fingers to hold the scraper. Use a little force to put the putty on the whole batch. You can't go back and forth repeatedly. Don't use the scraper to scrape the excess putty around when you put the putty. Prevent from hitting hard objects and scratching the blade. The horn blade is easy to deform, wipe it clean after use, insert it into the slat or press it under the weight to prevent deformation.
4. The steel scraper is made of 0.5?1mm thick spring steel plate. Large and small width is 5-12cm, length is 8-10cm, and the upper side is ground into a circular arc shape on the grinding wheel. It should be ground to a narrow upper and lower width, with a certain inclination on the upper and lower sides, and the lower end of the lower edge is ground into a thin mouth, such as a kitchen knife. The mouth is like this, so it is good to putty.
5, the plastic scraper takes a multi-layer resin sheet, made of phenolic resin board, etc. The size, shape and mouth grinding are similar to the steel scraper. Steel scraper and plastic scraper are used for the coating of large area putty. It not only saves labor, but also puts out the putty.
Second, the skill of scraping putty
1. The wall surface is treated. The base layer has the same requirements as the white ash knives. The wall top, the slats, etc. will clean the floating ash, remove the residual debris and protruding parts, and use the mortar to level the holes, the door and window openings. The gap between the beams is tight and the corners are smoothed and smeared with 1:3 cement mortar. The verticality and flatness are in line with the requirements of the specification, and the yin and yang angles are square. The bottom ash surface is flattened with wooden rafters.
2, ç ¼, mortar wall surface up to 70% dry can be directly applied, a number of transparent should be watered and wet.严é‡When the wall is heavily stained, brush it with 10% alkaline water or washing powder, then wash it with water. Generally, the oil can be sanded with sandpaper.
3, for the wall with fast water absorption, it is best to spray with a 1:2 or 1:3 107 aqueous solution to prevent the gypsum powder from losing water too quickly and appear powdering phenomenon. The plasterboard wall should be wiped with a wet cloth and then covered.
4, white mortar, cement mortar, mixed mortar bottoming wall, until the bottom ash dry to six to seventy percent can be covered, if the bottom layer is too dry, it should be watered and wet. Generally, the cover can be carried out 2 to 3 days after the bottom ash is wiped off. The gypsum plaster should be smeared first and thinly, then leveled and calendered. The total thickness of the two passes should not exceed 2mm. The yin and yang angles are set with a square ruler and then calendered with a small pressure. The wall surface or the gypsum board wall surface is treated by a scraping method, and scraped twice with a steel plate scraper or a squeegee, and the thickness is 0.5 to 1 mm.
Third, what should pay attention to the putty tool
1. After the plaster putty is used up, the construction tools should be rinsed off with water in time.
2. The hardened gypsum putty can not be reused with water and stirring.
3. The bagged putty powder should be stored in a dry place, and there should be no moisture and agglomeration deterioration before use.
4, to adjust the putty powder to use clean water, water should not contain harmful substances such as sulfides.
