.Friends, have you ever encountered this kind of trouble?Why did I feel that the "face" of the carefully selected, brightly colored acrylic topcoat was getting worse and worse not as full as before, not long after I applied it?Did I buy a fake, or was the construction not done well?

Don't worry, today we will talk to you from the bottom of our hearts as a "old master" who has been working in the paint industry for many years.The fading of acrylic topcoat is not necessarily due to poor product quality. In many cases, it is caused by several "invisible killers".Let's pick them out one by one.

Killer 1: The foundation is not laid well, and the "scrubbing" of the wall is not in placeWhen we paint, we are like building a house. If the foundation is unstable, the house will have problems sooner or later.Before construction, if the rust, oil, and dust on the surface of the wall and steel are not cleaned off, or the polishing is not smooth enough, the paint film will not "stick" firmly to the base material.This will cause the paint film to be uneven in thickness, causing random reflections when light shines on it, making it look like the color is darker and lighter, and it feels "faded".Therefore, when cleaning and polishing before construction, the "scrubbing" time cannot be spared.

Killer 2: Ultraviolet rays, the most ruthless “sunlight bleach”Ultraviolet rays from the sun are the number one enemy of almost all outdoor paint colors, and Acrylic Paint is no exception.It does not "sun-out" the color, but acts like a knife, continuously destroying the chemical structure of the resin and toner in the paint film.Over time, the paint film will lose its luster, the color molecules will "change", and it will look dull and white.This is like a bright piece of clothing, if it is exposed to the sun every day, no matter how good the material is, it will inevitably lose its color.

Killer Three: Humidity and water vapor, the silent "color porters"Although acrylic paint is water-resistant, it cannot withstand long-term exposure to high humidity or direct water seepage.Moisture will slowly penetrate into the paint film, interfering with the close "hand-in-hand" relationship between the resin and the pigment, and may also trigger some chemical reactions.Over time, the color is "moved" or "changed".Especially if the primer is not applied properly, or the substrate itself has moisture, the problem will be more serious.

Killer 4: If you are greedy for cheap, you may fall into the "inferior quality trap"There are some low-priced products on the market. In order to control costs, the resin and color paste used are of poor quality and the production process is rough.For such paint, the structure of the paint film itself is "loose", like a piece of tattered clothing with holes everywhere. It cannot block the attack of ultraviolet rays and water vapor at all, and it will naturally fade quickly.Counting the labor and material costs of repeated repainting, the money saved in the early stage may have been lost long ago.

Killer Five: The construction is not standardized and the craftsmanship becomes "out of order"The last point is also the point that is most easily overlooked by everyone - construction.The primer and topcoat do not match each other, topcoat before the primer is completely dry, paint too thin, or add more thinner at will... These operations will cause shortcomings in the "protective armor" of the paint film, greatly reducing the overall performance and causing premature aging and fading.

To summarize:If you want the acrylic topcoat to be long-lasting and bright, you need "a good horse with a good saddle" - high-quality paint is the foundation, standardized construction is the key, and proper maintenance is the guarantee.All three are indispensable.
