Jack's application skills in wet weather?

1, paint bubbles. First, the bubble will burst. If there is water coming out, it means that there is water oozing under or behind the paint layer. After exposure to the sun, the water will evaporate into steam, and the paint will be jacked up into bubbles. At this point, first use a hot air spray gun to remove the foaming paint, let the wood dry naturally, then brush the primer, and finally repaint the whole repair surface. If there is no water in the bubble, it may be that the wood grain is cracked and there is a small amount of air inside. After the sun shines, the air expands and the paint skin bulges. Faced with this situation, first scrape off the blistered paint skin, then fill the gap with resin filler and repaint it, or directly apply microporous paint without filler.

2. cracks appear. In this case, the paint should be removed by using a chemical stripper or a hot air spray gun, and then repainted. If the fracture range is not large, you can use a sand grinding block or dry and wet sandpaper to grind off the broken paint. After the surface is polished and smooth, apply putty, brush primer and repaint.

3. The paint surface is rough. The surface of the new brush is rough, usually because the paint brush used is unclean or polluted by the surrounding environment. It is also possible that the paint is mixed with patent leather and has not been precipitated and filtered before use, or the paint is wet and dusty. In order to prevent the above problems, clean paint brushes and paint buckets must be used. Old paint must be filtered with paint filter paper or clean nylon stockings before use. In addition, when the paint is wet, cover the paint surface with a cover or cardboard to prevent dust. If the paint surface is rough, after it is completely dried, polish it with dry and wet sandpaper, and then repaint it after wiping. In particular, the paint brush must be clean.

4, lose luster. The reason is that there is no primer directly varnished, or the primer and inner paint are not completely dried. As a result, the varnish was absorbed by the wood and lost its luster. The poor quality of varnish is also a reason. Use dry and wet sandpaper to grind off the old paint, brush off the dust after grinding, wipe the surface with a clean wet cloth, and brush the top coat again after drying. It is particularly important to note that the paint film may lose its luster when painted in a very low temperature environment.

5. Insects stick to the paint. Try to scrape off the bugs before the paint is dry, and then gently repair the surface with a brush with a little oil. If the paint has started to dry, wait until the paint film is completely hardened, and then wipe off the bugs to avoid making a mess of the surface.

American Jack Coatings Co., Ltd. tells us that the problems of paint and coatings usually occur in the process of spraying. As long as we pay a little attention to these small details, we can basically solve the problem. Most of us don't pay much attention to these details at ordinary times, and we realize the problems at that time only after the problems appear, which requires us to change our concepts in order to achieve first-class workmanship.
