To prevent furniture coating problems, these three points are very important!

The arrival of spring is also often the time of coating ills, paint cracking, slow drying, sticky sandpaper, loss of light and other paint diseases, then, how to prevent and avoid the above problems?
, the construction environment should not ignore
before the construction to clean up the construction of environmental health, to avoid the environment unclean and dust and affect the effect and quality of paint film.
II, paint deployment is very important
1, do not arbitrarily multi-reinforcing agent or use non-matching fast-dry curing agents, thinners, etc., which will lead to paint film too brittle, cracking, yin and yang surface, loss of light and other ills; The drying speed is adjusted by using thin coating many times, or by improving the construction environment and heating facilities, 3. Select the appropriate thinner: use a universal diluent when the temperature is 15-25 degrees C, use summer diluent when the temperature exceeds 25 degrees C, and use winter diluent when the temperature is below 15 degrees C.
3, construction operation is the key
1, low temperature does not construction: the temperature is too low, the paint will not react fully, easy to appear paint film drying too slowly, poor hardness, poor adhesion, paint film wrinkle, gloss is not equal and other paint film ills .
2, appropriate heating: PU paint construction environment temperature needs to be higher than 5 degrees C, water-type wood paint construction environment needs to be above 8 degrees C, the temperature of the room to be dry to be kept above 15 degrees C, otherwise, it is recommended that the construction and drying room to carry out the necessary heating and warming measures.
PE paint at low temperature, the addition of excessive blue, white water will cause hair green, pinholes, cracking and other paint film ills.
3, strictly prohibited thick coating: it is recommended to use thin coating many times the construction process, strictly prohibited one-time thick coating, especially for door panels, desktops and other graphic construction sites.
Because the temperature is low, the construction of a spray too thick, paint film easy to appear in the table dry not dry, causing the paint film whitening, wrinkled, dry too slow, hardness is not good and other ills.
4, control interval time: it is recommended to use wet touch wet coating process, to control the interval time of the coating, pay attention to the interval time should not be too short, no table dry do not construct the lower layer.
coating at low temperature reaction drying is slow, if the first layer is not dry on the construction of the lower layer, prone to late whitening of the paint film, poor drying, bottoming, wrinkles and other ills.
5, the bottom good surface is good: low temperature PU solid color primer drying easy to be alternating due to hot and cold temperature difference, substrate telescopic deformation lead to cracking, especially the wire, groove, slug connection site;
6, plate closure: for the plate to use a special closed paint to do a full closure treatment, especially oily or high water content of the substrate (such as teak, pine, etc.);
, moisture and medium fiber plate absorbent expansion and other characteristics, easy to cause furniture variants, paint film de-layering, cracking and other ills.
7, dry through grinding clean: putty layer to be fully dried after polishing clean, so that only "fill the wood eye, do not leave a wooden path", can not be thick left a layer of putty to increase the thickness of the paint film.
8, water grinding dry through: the use of water milling process, to keep the plate completely dry, to prevent water not dry and cause paint film whitening and other paint diseases appear;
