Of course, the steps of painting can not be reduced in the decoration. In particular, many products are currently uneven. If you don’t buy well-known brand goods, it is easy to have various problems. The following small series for you to analyze the common problems of various paints, and teach you a few smart solutions, complete your home renovation!
1. Cracks appear:
In this case, it is mostly necessary to remove the paint with a chemical paint remover or a hot air spray gun before repainting. If the fracture range is not large, the sanding block or wet and dry sandpaper can be used to wet the water, and the broken paint is ground. After the surface is smoothed, putty is applied, the primer is applied, and the paint is repainted. 7 major problems in paint and coatings
2, paint film wrinkles:
Usually caused by brushing the paint a second time because the paint is not dry for the first time. At this time, the solvent in the undercoat affects the upper paint film and wrinkles it. In this case, the creped paint film can be removed by chemical mercury removal or heating to repaint. Remember, you must wait until the first time the paint is dry before you can go to the second time.
3, paint hooligans:
If the paint is too thick at a time, it will cause runny. The paint can be dried and brushed with a brush. If the paint has begun to dry, wait until it is dry. Smooth the surface with a fine gauze paper, brush the surface clean, then wipe it with a damp cloth, then re-coat the outer layer. Be careful not to brush too thick.
4, paint peeling:
It may be that the surface is too smooth. If the original paint is lacquered or powdery (plus untreated paint coating), the new paint will not stick to the surface. Or it may be wood decay or metal rust spots, but also peeling off due to poor paint quality. A small area of ​​paint peeling off, can be sanded with fine gauze, then put on putty, brush the primer, and then repaint. Large areas of peeling must be stripped of the paint and repainted.
5, moldy discoloration:
This problem occurs mostly on wet paint surfaces, such as water vapor condensation on glass and metal surfaces that often produce brown-black stains. At this point, the fungicide can be used to treat the moldy parts according to the instructions of the instructions. After the mold is killed, the surface is cleaned and then repainted.
6, stains:
There are many reasons for stains on the paint surface. For example, the water in the latex paint dissolves the material on the wall and rusts the paint surface, and the wall surface rubbed with steel wool produces rust spots. The dark pipe in the wall leaks stains and the like. To prevent stains, first apply a primer containing aluminum powder. If stains have appeared, remove the latex paint from the stains, brush the primer containing aluminum powder, and then repaint.
7, loss of luster:
The reason is that the primer is not applied, or the primer and the inner layer paint are not dried, and the varnish is directly applied. As a result, the varnish is absorbed by the wood and loses its luster. The bad paint is also a reason. Use old wet and dry sandpaper to rub off the old paint, brush off the dust, wipe the surface with a clean damp cloth, and then dry it again. It is important to note that painting in a very low temperature environment may also result in loss of gloss after the film has dried.
Why AHD?
As the industry moves from standard definition to high definition, how can we ensure the whole surveillance system not only satisfies the resolution requirement, but also the total cost?
Super Video Technology presents Analog High Definition(AHD) technology to the market. AHD is an over-coaxial-cable analog HD video transmission standard, allowing long-distance HD transmission at a lower cost to meet the requirements for a complex and large installation.
How AHD can be beneficial to us?
• Upgraded to analog HD seamlessly with Low-cost and simple installation value-added solution. Go after the conventional analog system topology and give a full consideration to users' operation habit.
• Megapixel & uncompressed image quality.
• Long range & non-latency reliable video transmission without additions of relay devices.
• Strong anti-interference capability & solid interface protection. Free of high-frequent electromagnetic radiation; constant signal transmission and display without problems as frame drop and lock loss occurred.
• An open analog HD transmission system established and evolved industry chain developed to sustainably improve the technical standard.
