Water-like wood paint construction tips, hurry to collect it.

Water-based wood paint, water as a solvent without any harmful volatilization, is currently the safest and most environmentally friendly wood products with paint, its production process is a simple physical mixing process. However, due to the coating effect and coating process and other comprehensive factors, water-based wood paint in the domestic market share is not high, but its low-carbon environmental protection concept is definitely the future direction of furniture paint development, I believe that with the continuous progress of technology, water-based wood paint applications will be more and more extensive.
Although there are many water-based wood paint brands on the market, but according to its main components, can be divided into the following four categories:
1, acrylic as the main component of water-based wood paint
the main feature is good adhesion, will not deepen the color of the wood, but wear resistance and chemical resistance is poor, paint film hardness is softer, pencil test for HB, poor plumpness, comprehensive performance in general, construction prone to defectsBecause of its low cost and low technical content, it is the main product that most water-related paint enterprises bring to market. This is also the reason why most people think that water-like paint is not good. The advantage is that it is cheap.
2, acrylic and polyurethane synthesis as the main components of the water-based wood paint
its characteristics in addition to adhering to the characteristics of acrylic paint, but also added wear resistance and strong chemical resistance characteristics, some enterprises marked as water-based polyester paint. The hardness of the paint film is better, the pencil method test is 1H, the plumpness is better, and the comprehensive performance is close to the oily paint. At present, only a few enterprises in China can produce.
3, polyurethane water-based paint
its comprehensive performance is superior, high plumpness, paint film hardness can reach 1.5-2H, wear-resistant performance even more than oily paint, service life, color deployment have obvious advantages, for water-based paint in the advanced products.
4, pseudo-water-based paint
use should also add curing agents or chemicals, such as "hardener", "paint film enhancer", "special dilution water" and so on, some can also be diluted with water, but the solvent content is very high, more harmful to the human body, some even more toxic than oily paint, and some enterprises marked as water-based polyester paint. It's easy for consumers to tell.
for water-like wood paint construction is relatively easy to produce problems, put forward some solutions, so that wood products processing you more handy.
01, water-like paint peeling, layering
causes: the surface is too smooth, the object is not clean, wood decay, metal rust spots, water-like paint quality is poor.
wood or metal surface has a small area of paint film peeling, varnish can be polished with fine sandpaper after brushing, color paint can be partially polished or batch putty, and then repainted. Large areas of peeling must wash (scratch) all the paint, and then repaint.
02, water-like paint foaming
cause 1: the paint layer under or behind the moisture is too heavy, drying process (or sun), the moisture will evaporate outwards, the paint film top bubble. In this case, first use a hot air spray gun to remove the foaming paint film, and then let the wood under the natural drying, and then partially brush the primer, and finally repaint the entire board.
2: If the wood cracks and there is a small amount of air in the wood, the paint skin bubbles as soon as the sun shines and the air expands.
face this situation, scrape off the foaming paint, then fill the cracks with putty and repaint. You can also use putty, scrape off the paint, directly coated with micro-hole paint.
03, cracks (color paint, mixed water color)
this situation is most likely to use chemical decolorizer or hot air spray gun to remove the paint, and then repaint.
If the fracture range is not large, then you can use sand scrubs or dry and wet sandpaper water, grind off the broken water-like paint, after the surface is smooth, batch putty, paint primer, and then repaint.
04, water-like paint flow
water-like paint brush too thick at a time, that will cause flow. Can take advantage of the paint has not yet dried, brush the paint open, if the paint film becomes dry, then wait for it to dry through, with fine sandpaper to polish the paint smooth, clean the surface, and then repaint. Be careful not to brush too thick.
05, stains (for color paint) and
surface of water-like paint to produce stains for many reasons. For example: latex paint in the water melts the material on the wall and seeps out the paint surface, with wire velvet rubs the wall will produce rust spots, the wall of the dark pipe leakage appears stains and so on. In order to prevent stains, you can first brush a layer of rust-proof primer, if there have been stains, you can first remove stains (such as latex paint, etc.), and then brush a layer of rust-proof primer, and then repaint.
06, moldy color change
this kind of problem occurs in the wet water-based paint surface, such as water vapor condensation on the glass or metal surface of the water vapor and paint film combination, will produce brown-black stains. At this time can be used fungicides, against the instructions of the instructions to deal with moldy parts, after the mold killed, clean the surface, and then repaint.
07, loss of luster
one of the reasons is that it may not be on the primer, or the inner paint is not dry on the paint directly painted on the half-light or bright paint, the result of the paint is absorbed by the wood and lose luster. It may also be that the quality of glossy paint is poor.
treatment: use dry and wet sandpaper to grind off the old paint, the surface polished dust wipe clean, to dry through, and then repaint.
special tip: in the very low temperature environment paint, paint film dry, may also lose luster, this is the paint film into a bad film.
8, paint film wrinkled
is usually caused by the first paint is not dry or brush the second time - that is, not dry brush, also known as wet wet construction. At this time, the upper and lower layers interact with each other, making it wrinkled.
this condition can be removed by chemical depainting agent or heating method to remove the wrinkled paint film, repaint. Remember: be sure to wait for the paint film lying dry underneath before you can brush it a second time.
9, paint rough
1) new painted surface rough
usually the paint brush used is not clean or the construction environment is not clean. It may also be water-based paint mixed with paint skin or other impurities, before use without precipitation or filtration, or it may be water-based paint film is not dry when dust.
to prevent these problems, clean paint brushes and barrels must be used. Be sure to filter the old paint before using it. In addition, the painted surface should be covered with a cover or cardboard when the paint film is not dry to prevent dust.
if the paint is brown, after it has dried through, smooth and cleaned with dry and wet sandpaper, then repaint the finish. Special attention: Try to use a clean paint brush.
2) Dark spots appear on the surface of the painted wood
it may be caused by the wood section being unsealed before painting, by the sun, the wood section is hot, and the oil of the wood itself seeps out of the wood section. At this point, you can use a scraper to scrape off the water-based paint, and then with fine sandpaper polish to reveal the wood section, with a sealing paint to seal the wood section, to be dried through, and then repainted.
10, water-like paint is not dry
indoor ventilation is not good, the temperature is too low and indoor humidity is too heavy, resulting in water-like paint film dry. Water-like paint is already slow to dry. We can properly open doors and windows for ventilation, or put a heater indoors to increase room temperature.
11, paint stick to the bug
try to take advantage of the watery paint is not dry when the bug removed, and then use a brush with a little paint gently repair the surface. If the water-like paint has begun to dry, then wait until the paint film is completely dry, and then wipe off the bug, so as not to make a mess of the surface.
