Little knowledge about roller brush

First of all, we should understand that the quality of roller brush is determined by the plush density of roller brush: high-quality roller brush has a large plush density of more than 950 grams per square meter, a large amount of paint dipping, a large brushing area, a firm plush, not easy to fall off, and does not open the thread. Long service life, smooth rough surface. However, the density of plush of low-grade roller brush is below 700g per square meter. Weaving is loose and easy to shed wool.

Secondly, according to the type of wool, 100% acrylic fiber is of good quality, good paint dipping and high price, while the wool containing a certain proportion of polyester fiber is cheap. The quality of the plush of the roller brush head determines the service life and effect of the roller brush. At the same time, 60% of the cost of a roller brush is determined by plush.

According to the length of brush hair, it can be divided into three types: long hair, medium hair and short hair. The construction effect of roller brush is different according to the length of brush hair, as follows:

The paint surface is relatively flat and smooth after the construction of short-hair roller brush.

Fine concave-convex shape will appear after the construction of long-hair roller brush.

The construction effect of medium hair roller brush is between short hair and long hair.

There are also many sizes of roller brush, including 2 inches, 4 inches, 6 inches, 8 inches, and 10 inches. One inch is about 2.54cm. In case of large area construction, roller brush above 6 inches is applicable.

The purpose of roller brush is to brush paint, floor paint, etc. It can also be applied with various emulsion paint, interior and exterior wall paint, anti-rust paint, wallpaper mounting adhesive and other mixed paint. The advantage of roller brush is that it is very convenient to use, and it can be applied directly and straight. If you want to apply evenly, the roller needs to be put into the paint bucket. After it is fully absorbed, roll it on the slope for several times, press out the excess paint and then start to paint the wall.
