The use of latex paint in home decoration is becoming more and more common, and in addition to the common roll coating and spraying, the use of a brush (paint brush) to paint is also a common construction method. When industrial paint brushes use paint brushes, pay attention to the following tips, which will make the entire construction process more efficient and effective.
1. When applying latex paint, try to use artificial polyester, nylon brush wire or high-quality wool brush for the brush roller to avoid problems from the source. A good brush, when held in your hand, should have a good feel: not slippery, rough, and comfortable. When choosing a paint brush, pay attention to the following points:
(1) The wool brushes selected from sheep’s tail hairs and made with a single production process have the best quality.
(2) The end of the wire brush can buckle to a certain extent and can easily rebound back to its original shape.
(3) The size, type and quantity of brushes purchased shall be commensurate with the project scale. In general, you should have both a large and a small brush. The bristles can be flat, pointed, or angled. It depends on whether some special shapes are encountered in the project.
2. Master the correct brush usage method to minimize the occurrence of stagnation brushes.
Many paint suppliers will specify the correct application procedure in the instructions: immerse and wet the new brush in clean tap water before use, usually soaking for 10 to 15 minutes. The ideal method is to soak the brush with 1% washing powder in tap water (preferably hot water).
When the brush is dipped into the paint, reach under the liquid into the tank up to half the length of the bristles, preferably 1/3. After dipping the paint, you should touch the tank wall several times with the tip of the brush to make the paint brush full of paint without dripping.
When painting, the angle of the line brush should be 45 relative to the surface of the paint. During wall and ceiling construction, the line brush should be vertical, the brush stroke should be long, and the wall should be light. When painting wood, brush it down.
When brushing oil-based paint, brushing back can improve the appearance of the paint film, but when brushing latex paint, especially semi-gloss or glossy paint, do not brush back. Applying latex paint requires a thick film and good hiding power, and brushes cleanly to achieve good results.
