1, zero VOC is the best? NO!
Well, VOC is an important indicator of the environmental protection of coatings. Normally speaking, the lower the better, there is no shortage of products claiming zero VOCs. But! Yes! The VOC content is reduced, the viscosity of the coating will be relatively low, powder coating, foaming, and cracking will occur one after another. You are looking for someone to cry no place ~~ again, you want to reduce the VOC content, manufacturers As long as it is mixed with water, it can be done! In fact, coating VOC content has a national standard that is harmless to the human body and can only be listed when it reaches the standard, so there is no need to pursue VOC content excessively.
2. No odor is environmental protection? NO!
Everyone knows that paints with pungent odors must be defective, and that products with no special smells represent environmental protection? Of course it is not enough. In fact, by adding flavor or low-odor material can be achieved coating odorless, so the odorless coating is not entirely environmentally friendly and non-toxic, the key is to see the authority certificate test report and formaldehyde test data ah!
3, the pursuit of self-cleaning and scrub resistance? NO!
Many rookies believe that the selection of paint must be scrub-resistant or with self-cleaning function, in fact, the dirt resistance of the paint does not imagine the magic of it.

It is really used at home, and cleanliness has to rely on human beings to be useful. And wear resistance... In fact, we have daily The number of scrubbing the walls is not really much, do not rely too much on the toss scrub function.

No no, good quality paint to a certain extent, slow down the wall cracking speed, but in addition to paint crack resistance, construction and maintenance is also a wall The key factor of surface crack resistance.
Second, the misuse of materials processing: do not mess things
Construction process for the use of the coating, whether it is a housewife or a cook, probably inevitably want to make the best use of, can not be used to waste it, but the paint is different from other building materials, can not save material!
1, save money and labor do not want to use primer? NO!
Is it possible to use a primer without a good finish? Of course not. Primer has a closed wall base layer to improve the multiple effects of paint adhesion, fullness, etc. If you do not paint the primer, then the top paint may cause the wall to paint too quickly too soon, even soon after the brushing Discoloration, flaking and other issues.

The remaining paint is also very common, white paint, varnish or can see if the neighbors can use it, but like the colored paint is left to be able to do it, and some people do this: just go back It's a big mistake to use waste. For paints that have been used for caps, the shelf life is very short and cannot be stored for a long time. If they cannot be used, they can only be drained by the relevant professional recycling department (cannot be poured into the sewer), or they can be temporarily stored in sealed containers. Container.
