What putty powder is used for home decoration for environmental protection? When doing home decoration, putty powder is essential. It is the basic material used to scrape walls and decorate our walls. Here's what putty powder is used for home improvement and environmental protection.
What putty powder is used for home improvement? Environmental protection 1 1, gypsum-based putty.
The main function of wall putty is to fill the wall foundation, protect the wall, beautify the building and environment, and improve the physical properties of wall materials. It is also quite special. Gypsum putty can be used by mixing with water without glue, which is very environmentally friendly and will not crack and peel.
At present, the application of gypsum putty is not much, mainly because people do not fully realize the performance advantages of this material and do little research on it. Adding functional additives to gypsum-based putty can make the putty film functional, such as hygroscopicity and releasing negative ions, which has been paid attention to and studied a lot.
Because our country is rich in gypsum resources, and there are no natural materials harmful to the environment, and because the room can produce hygroscopicity and breathability well, it can produce good health care effect and excellent decorative effect compared with the widely used organic coatings at present, so the application research of decorative gypsum-based putty should be strengthened.
2, cement-based putty
Cement-based putty has good workability, good water resistance, high bonding strength, good hydrophobicity and air permeability, but the cost is high. It takes 7 months for cement-based putty to completely dry, while it only takes 3-5 days for gypsum-based putty. So gypsum-based is better than cement-based in terms of constructability and appearance after construction.
3. Cooked rubber powder
Cooked rubber powder is made from potato starch through special modification and drying. This is a kind of modified starch. Cooked rubber powder is its trademark name. Because it dissolves in cold water, it is named cooked rubber powder. At present, the common cooked rubber powder on the market is esterified etherified modified starch. This product is soluble in cold water, has strong adhesion, is non-toxic and tasteless, is a green adhesive, and is widely used in putty rubber powder for interior wall treatment in construction industry.
Usage of cooked rubber powder: After adding powder, it can be used to paint concrete walls, making them smooth, not cracking when dry and not moldy when wet. It is a very environmentally friendly decoration product.
Advantages of cooked rubber powder: the special bulkiness can be well mixed with powder, and it is not heavy and has good water retention, which can prolong the opening time, allow construction workers to easily smooth the unique smoothness of walls and starch, greatly reduce the construction intensity, increase the construction area and improve the construction environment.
Gypsum putty, cement putty, old rubber powder, etc. They are all common putty types in home decoration, and they are all good putty, each with its own characteristics and advantages. But now many decoration masters recommend gypsum-based putty, and everyone can choose according to the actual situation in their own homes.

What kind of putty powder is used for home improvement? 3 what effect will putty powder render on coatings?
Removal of putty powder
Phenomenon: After the construction is completed and thoroughly dried, the powder will fall off when touched by hand.
Reason:
1. If the polishing time of the putty powder on the inner wall is not well grasped, the powder will fall off after the surface is thoroughly polished;
2. Exterior wall putty powder, the coating is relatively thin when facing. Under the high temperature in summer, the water volatilizes quickly, the surface layer fails to fully solidify, and it is easy to remove powder.
3. When the product exceeds the shelf life, the bonding strength is greatly reduced.
4, improper storage of products, after moisture absorption, adhesion decreased significantly.
5. The high water absorption at the grass-roots level causes the putty to dry quickly and there is not enough water to solidify.
Solution:
1. When the putty surface of the interior wall is polished, it is necessary to master the appropriate polishing time. The best polishing time is to polish the putty surface immediately after the watermark disappears. Practice has proved that the veneer 1~2m2 should be leveled or polished.
2. After the exterior wall putty surface is dry, it should be moderately polished and fully maintained by sprinkling water. In general, maintenance is divided into two or more times. If necessary, please use transparent sealing primer and water (1: 5) as the second spraying liquid, and the effect will be better.
3. The product must be used within the warranty period. If it exceeds the shelf life, it must be scraped and tested before construction.
4, the product must pay attention to waterproof treatment, should exist in a cool and dry place, and ensure that the packaging is intact.
5. In summer or in high temperature and windy climate, it is best to wet the wall with clear water before blowing putty, and then blow putty after there is no clear water on the wall.
Putty foaming
Phenomenon: bubbles are generated during construction, and the surface of putty bubbles after a period of time.
Reason:
1, the foundation is too rough and the setting speed is too fast;
2, a building putty layer is too thick, more than 2.0 mm.
3, the moisture content at the grass-roots level is too high, the density is too large or too small. Because of its rich voids, the putty is high in water content and airtight, and the air is sealed in the void cavity, which is not easy to eliminate.
4. After a period of construction, the surface burst and blistering are mainly caused by uneven mixing. Mud contains powdery particles that cannot be dissolved in time. After construction, it absorbs a lot of water and expands to form a burst.
Solution:
1, foam the putty surface in a large area, directly crush the small bubble mouth with a shovel, and blow the foamed surface with a suitable putty again.
2. Generally, after the putty is stirred evenly, let it stand for about 10 minutes, then stir it again with an electric mixer, and then go to the wall.
3, the construction of the second or last layer of surface foaming phenomenon, should be before the watermark is eliminated with a scraper to break the bubbles, to ensure that there is no bubble on the surface of putty.
4, particularly rough metope, general bottom material as far as possible choose coarse putty.
5, in the wall is too dry or strong wind and strong light environment, first wet the wall with clear water as much as possible, and scrape the putty layer after there is no clear water on the wall.
Putty shedding
Phenomenon: Putty has poor bonding strength with the base and falls off directly from the base.
Reason:
1, the old wall is very smooth (such as toughened putty, polyurethane and other oily paints), and the adhesion fastness of putty powder to its surface is poor.
2. The new wall is cast by formwork, with smooth surface and a large amount of release agent (waste engine oil or silica gel).
3. Used for non-mortar substrates such as wood substrates and metal substrates (such as plywood, plywood, particleboard, solid wood, etc. ), due to the different surface expansion and contraction ratios of this kind of products, it has strong water absorption, and the rigid interior wall putty cannot be deformed, and it will generally fall off after 3 months.
4. When the putty exceeds the shelf life, the bonding strength decreases.
Solution:
1, remove the abscission layer, and handle it according to the following conditions;
2. Grind the old wall surface to increase the surface roughness, and then treat it with interfacial agent (10% environmental protection adhesive or interfacial agent);
3. Use degreasing cleaning agent to remove the release agent or other grease components on the surface, and then blow putty.
4, using two-component or special plywood putty for construction.
5, marble, mosaics, tiles and other external wall surfaces, please use external wall renovation putty as the base.
6, used in putty warranty period.
The putty powder turned yellow.
Phenomenon: Shortly after the completion of construction, the putty turns yellow partially or completely.
Reason:
Mainly occurred in the old indoor walls. A large amount of PVA glue was used in the putty of the old wall. The aging and decomposition of glue produces unsaturated acid, which reacts with calcium ions in putty to produce corresponding yellow calcium salt.
Solution:
1. Roll-coat it twice with environmentally friendly glue, and then scrape the putty on the inner wall after it is completely dried;
2. Roll-coat two coats with sealing primer, dry thoroughly, and then blow putty.
3, all use paste putty construction, or use flat putty construction.
Putty stratification
Phenomenon: Two layers of putty or putty and the substrate peel off each other.
Reason:
1, and the base material contains a lot of release agents (such as waste engine oil and wax emulsion);
2. The matrix is severely pulverized and the water absorption rate is too high.
