Using bristle brush technique — Construction Industry

Bristle brush, commonly known as bristle, refers to the bristle growing on the neck and back of the spine of the pig, usually more than 5cm; bristle is rigid and tough, elastic, not easy to deform, resistant to humidity, high temperature, not affected by cold and heat, so it has always been one of the main raw materials for manufacturing the brush. As animal hair, bristle also has the function of anti-static, which can be used to process anti-static brush.

Bristle brush type:

1. Paint brush

Bristles were first used to process paint brushes, which are suitable for painting in construction, decoration, furniture and other industries. Bristle brush is solid and durable, with the effect of heavy paint coating, easy to clean at the same time, and can be reused. Commonly used bristle paint brushes include straight board brush, ceiling brush, row brush, round handle brush, etc.

2. Barbecue brush

Bristles are tough and not easy to break. They are made into barbecue brush after being washed with disinfectant water, which can be used for oil brush in barbecue process.

3. Glue brush

4. Spring brush

5. Industrial brush roller

6. Other bristle brushes

Construction skills of bristle brush:

In interior decoration, the gesture of holding brush is also very exquisite. Proper holding method helps to delay fatigue and make the work process neat and orderly.

The handle of frame brush and window frame brush is pencil like, so the grip of these two brushes is very similar to that of pencil, that is to hold them with thumb, index finger and middle finger. When holding the beaver tail grip with larger brushes, you need to use more force to hold them because they are wider and heavier. Hold the handle with your whole hand and make full use of the width of your hand, just like holding a tennis racket.

This technique works best when you are painting large flat surfaces.

To dip the brush in the paint, we should have a good measure: we can brush as much paint as possible on the wall, and at the same time, we can avoid the paint dropping on the floor and you during the painting process. This technique can be learned in a few minutes, the key is to be able to accurately control the amount of paint the brush contains. In particular, wet the brush hair before painting (dilute the emulsion paint with water, dilute other types of paint with corresponding diluent), so that the brush can adapt to the paint and paint more efficiently. Gently knock the metal plate around the handle of the brush on the palm edge to let the excess water flow into the pool or bucket.

When dipping in the paint for the first time, turn the brush slightly in the paint to open the brush and fully absorb the paint. Push the brush gently into the paint every time the paint is dipped, so that the brush can be dipped into the paint more easily. For most latex coatings, just dip the brush into the paint first, then lift the brush and wait for a few seconds, let the excess paint drop, and then use it to brush the wall. But when using thinner paint, you may need to tap the inner wall of the paint tank with a brush, or drag the brush through the inner edge of the tank mouth to remove the excess paint.

If you want to brush a straight line where two edges or two colors meet (this is called “brush connection”), you can use a frame brush with tapered bristles (the end of the brush is similar to a chisel). Brush five to six times in the direction perpendicular to the edge of the ceiling or wall. Next, start from the corner of the wall and brush in the direction perpendicular to the several coats just brushed, with a long distance, so that you can smooth the several coats you started to brush.

At the intersection of the wall and the ceiling, first brush the wall from top to bottom, and then brush the previous paint along the horizontal direction. On the ceiling, brush toward the center of the room, away from the wall. Then brush the ceiling horizontally along the direction of the wall to smooth the paint. Even if you use the same paint color on adjacent surfaces, you should follow this method of brushing, leaving a 5 cm wide border, rather than using a brush dipped in paint directly to the corner. This can prevent the paint from dripping and falling.

Another brush bonding method is “ridging”, in which the paint areas can be protected from each other without masking the tape. Use a long slant to finish the brush. The way to hold the brush is that the thumb is on one side of the ferrule and the other four fingers are on the other side. Gently press the brush onto the wall, and then move the brush while applying enough pressure to keep the bristles bent in the brushing direction. Keep the brush about 0.16cm away from the colored wall on the other side. The curved bristles and pressure will release small paint beads, which will spread to the blank area.

When using these two methods, especially when dealing with two colors, brush can be dry. It’s a delicate job. If you want the painting work to be effective, slow down each time, and brush 10.16 to 12.7 cm of paint. This job may seem a little boring at first, but your speed and accuracy will improve with the increase of practice. Even a normal sized house can give you many opportunities to practice.
