Exterior wall coating topcoat into pieces off putty and primer is the key

Three points paint seven points construction, on the exterior wall paint a variety of problems, the causes are more complex, not necessarily a symptom is a reason. This is just like seeing a doctor, such as "cough" is not necessarily a cold. Specific problems still need to be checked by experienced paint workers on site. If the wall paint film is torn off like paper, it does not mean that the paint is not good. On the contrary, the wall paint that can be formed into one piece is that the emulsion content is relatively high and the quality of the paint is relatively good. Sample of sand-in-water coating If there is no trauma to the wall and the paint topcoat falls off in pieces, there are several possible reasons: 1, the quality and viscosity of putty is not good; putty inside the glue. It is one of the important components of various putty. It is mainly to play the role of the connection between the various substances. Putty glue content is not enough, it will lead to putty itself off powder. If the putty structure itself is not strong. Even the best topcoat can be easily torn off the wall. Water-in-water coating works 2. The primer is useless or the quality of the primer is not good, and it does not work; The role of the primer: one is to seal the alkali, to prevent alkaline penetration into the surface, affecting the visual effect of the surface. The second is solid bottom, penetrate into the grass-roots level, solid putty layer, play the role of connecting putty and topcoat. If the primer can not secure the putty, it will lose the function of this code, and the latex paint will be torn off the wall after painting. Some coating agent dealers, the topcoat as a primer to sell, is not enough, because the function of the bottom and the function of the topcoat is completely different. 3, putty is not dry on the primer, once the paint is not dry on the second time; The length of time the putty is completely dry has a great relationship with the climatic conditions at that time. If the weather is good and the air humidity is not high, the time required for the putty layer to dry will be shorter, otherwise it will be longer. In good weather (when the temperature is about 25 degrees), the putty can be scraped once a day, and it usually takes three days for the putty to be twice. This process, can't worry, must wait until the putty layer dry, can be polished, brush paint. However, the time for the primer and topcoat to dry out needs to be determined according to the area of the room, and the actual weather conditions should also be considered. In rainy days and when the air humidity is large, the interval time should be appropriately extended. Under normal circumstances, the first topcoat can be brushed 3 to 4 hours after the primer is brushed, and the second topcoat can be brushed after 2 to 3 hours after the first topcoat surface is dry. True stone paint works 4. Too much ash on the wall; Too much ash will also affect the layering of latex paint and putty. If you want to avoid some common latex paint diseases on the wall surface, you should avoid some common mistakes during construction, such as: don't use putty too badly; Every time putty and latex paint have to wait until the previous one is completely dry and then the second time. Latex paint cannot be mixed with too much water (especially when the materials are wrapped out, the decoration company will save as much as possible); Primer should be used, not directly painted, etc.

Milling machine set off new power for road reconstruction

In late September, the management section of Gejiu Highway introduced asphalt pavement milling machine for the first time for pavement treatment. In a short period of two days, more than 10,000 square meters of pits and subsidence were treated, which not only greatly accelerated the progress of road repair, but also significantly reduced the impact on passing vehicles. "The asphalt pavement milling machine is too good. It was supposed to work for more than a month and it was finished in two days. The work efficiency is really high." A road worker said. Before the road repair need to use artificial or mechanical road after the eradication of broken, not only the construction speed is slow, but also produce noise and dust, after the use of milling machine greatly shorten the road surface repair time, compared with the previous traditional construction methods, not only greatly improve the speed, repair quality is also very high. The labor intensity, operation safety and working environment of the staff have been greatly improved. The asphalt pavement milling machine can lift 20 to 30 meters of damaged road surface in one minute, and can clean 500 square meters of road surface per hour, while the manual digging and mending pits is only 6 square meters per day. Not only that. It strips off the damaged road surface evenly, does not hurt the roadbed, and is easy to resurface. After milling, a neat and flat milling surface and a straight milling boundary are formed to create conditions for re-paving of asphalt mixtures. After repair, the new and old paving layers are well connected and the joints are flush. The cut asphalt mixture can be directly used for the pavement surface layer, mixed with new asphalt heating, and then re-paved with high-quality surface layer, to avoid the waste of resources.

Old epoxy floor transformation why must use heavy grinding machine

After a certain degree of use, the epoxy damage on the ground before construction is relatively severe. After the heavy object passes, the epoxy on the ground is pressed out immediately. Deep traces, epoxy surface damage. If the weight of the grinding machine is not enough to achieve the grinding effect, such a ground to do curing must first beat off the surface Epoxy. During the construction process, although the peeling phenomenon is serious, the epoxy in some places is still attached It is more dense, so if the machine does not have enough weight, it is difficult to completely remove the epoxy on the surface. Qing Qin Yu's environmentally friendly heavy grinder is just right for it. 1. Durable and low maintenance cost. Our construction personnel often ignore the quality of the machine to determine its durability. Degree of durability High, but also can reduce the use of maintenance costs. It's like having a good quality car and taking a long trip, During the trip, you don't have to worry about the trouble in the journey, you can enjoy the pleasant scenery all the way. 2. adapt to all kinds of complex ground, let you construction easily. Regardless of the old and new ground, whether uneven or not, regardless of the table Face hard and loose. It can cooperate with different working conditions, let you hand over a good floor, become a good helper in your classic floor.
