The quality control department is out! Water-resistant putty is required on public walls from October 1

China Paint Online News Information
Look at the stairwells, elevators or other public walls of your house, whether there is mold, powdering, shedding and other phenomena. In wet areas, such problems are more common on public walls. The quality supervision department is finally out! October 1st, in addition to the National Day, there is a signal you have to know.
Shandong Weihai City Quality Supervision Station requirements, from October 1, 2016, new residential construction stairwells, corridors and other public parts of the ground need to scrape putty walls, as well as new public buildings stairwells, elevators need to scrape putty walls, design units to Construction drawings clearly use
water-resistant putty
for new public buildings, residential construction projects underground garages, basements and other public parts of the wall that need to scrape putty, moisture-prone, the design unit should clearly use water-resistant putty or external wall putty in the construction drawings. (From Weihai Evening News)
the purpose is very clear: to prevent the building indoor public parts of the wall fall off damage, to ensure the durability of the wall and the quality of the perception.
this time the Quality Supervision Bureau asked this year's National Day to start the implementation of the "wall use water-resistant putty" policy, for you to analyze the reasons.
1, compared with ordinary putty, water-resistant putty mainly has the following characteristics
1, water-resistant, moisture-resistant, mold-proof
If the eastern and southeastern coasts and other environmental humidity is high, rain is wide, especially in typhoon-prone areas using ordinary putty, putty layer absorbs external tide, moisture, easy to loosen, powder, for mold to provide crazy long conditions, the wall is prone to mold, and even peeling phenomenon. And water-resistant putty water-repugnant strong, will tide, moisture blocked outside, strong putty layer, water-resistant, moisture-resistant, mold-proof, to protect the wall coating quality and service life.
the last "Nibert" typhoon, a resident of The East of Shaoqing destroyed his home after it was washed away and soaked in the 100-year-old house. The water washed away, the first floor was basically soaked in water, its small building on the outer street corner has collapsed, and the central lobby was less damaged, different periods of the wall has a different ending - the previous part of the room wall using ordinary putty, the wall Serious powdering, shedding, and the late coating of part of the room wall is the use of large artisan environmental putty, the wall is strong, flat, intact, even mold spot is not, just use a cloth can scrub away the flood to the wall brought traces. The resident even praised the big artisan's water-resistant putty water resistance as really good.
2, good durability, secondary decoration do not have to eradicate
ordinary putty due to poor water resistance, later re-decoration must be together with the original paint to eliminate clean up, and then scrape putty again. Not only increase the cost of decoration (material costs, labor costs), the waste removed also caused waste of resources, difficult to recycle, but also pollute the environment. Water-resistant putty once and for all, after several years of second, third or more decoration, no longer shovel down the putty layer, polishing the surface, local repair can be carried out the next process, etc. , saving time and effort and protect the wall.
3, save the amount of paint
traditional putty has a strong water absorption, when the first latex paint brush, the coating film is not yet fully leveled, the water in the paint is absorbed by the bottom putty, so in the traditional putty surface brush latex paint because of fast water absorption, poor leveling. Resulting in the coating of the finished product after the coating film is not smooth and delicate enough, but also more consumption of latex paint. The unique whiteness and density of water-resistant putty, so that its unit area coating adhesion, cover rate than the use of ordinary putty wall to save 25 to 30% of the amount of paint.
4, high bonding strength
JG/T298-2010 "Indoor putty" standard for putty strength has been clearly defined, the standard state bonding strength of ordinary putty is greater than 0.25MPa, there is no requirement for the strength after immersion, and water-resistant putty requires the standard state bonding strength of 0.50MPa, after immersion bonding strength is greater than 0.30MPa. Through the standard can be seen that the strength of water-resistant putty is higher than ordinary inner wall putty, so the use of water-resistant putty is not easy to produce empty drums, shedding.
5, low comprehensive cost
the use of large artisan water-resistant putty, construction without any ingredients, just add water, there is no need to spend additional money to buy white latex, glue and other ingredients. So that water-resistant putty after the wall decoration effect and service life is far from ordinary putty. And from the amount of paint and secondary decoration of putty costs and construction costs combined calculation, the cost of using water-resistant putty is lower than ordinary putty.
II, water-resistant putty and traditional putty environmental protection comparison
traditional putty not only water resistance is very poor (immediate melting in case of water), and the glue used to reconcile putty contains free "formaldehyde". Formaldehyde is a recognized carcinogenic chemical with a volatile cycle of several years. Home decoration wall area of about 70% of the entire house space, the wall to be full of 2-3 times the traditional putty need to use a lot of glue. A household uses less than ten barrels, more than dozens of barrels. After the completion of construction, the living air will be filled with a certain amount of free "formaldehyde", long-term life, inevitably bring harm to health.
Inner wall water-resistant putty such as large artisan environmental protection water-resistant putty selected world-class core raw materials - Germany imports can be dispersed latex powder, the use of international advanced German environmental protection non-toxic formula, in line with international environmental standards, does not contain any free formaldehyde, benzene, harmful heavy metals and harmful volatile organic matter. And water can be built, save time, the use of water-resistant putty coated wall environmental protection and health, to protect the home environmental protection 70% of the healthy space.such as Shandong, Jiangsu, Zhejiang, Shanghai, Guangdong and other eastern, southeast coastal areas, especially typhoon-prone areas full of rain, high overall humidity throughout the year, in the wet season, the wall is prone to mold. Moldy walls not only affect the aesthetics, cracking, shedding and other persistent diseases to deal with it is also very troublesome, to life and living environment also bring a lot of inconvenience. The use of water-resistant putty on the walls of public buildings has been implemented, which also illustrates the importance of water-resistant putty to ensure the quality of wall coating.
