Painting is an essential part of the renovation process because the quality of wall paint directly affects the quality of the entire home renovation, so how can you paint the walls perfectly? What tools are used when painting walls? What are the primary uses of these paint tools? This article will give a detailed introduction and tell us what we need to pay attention to when painting.
How to Paint the Wall?
Sandpaper to sand the wall
The sandpaper used to sand the wall during the renovation will generally choose dry-grit sandpaper. Dry sandpaper with synthetic resin as a binder silicon carbide abrasive bonded on top of latex and coated with an anti-static coating made of high-grade products, with the advantages of anti-clogging, anti-static, good softness, high abrasion resistance. Various finenesses are available, suitable for grinding metal surfaces, putty and coatings. This product is suitable for dry grinding because of its high grinding efficiency and low stickiness to chips.
Why do walls need to be sanded?
This is because there are some minor defects in putting scraping, such as stubble at the junction of the putty, traces of thin or thick scraping, pinholes caused by water absorption on the wall, etc. The overall polished putty surface structure is more uniform and consistent, which can enhance the performance of the emulsion paint and avoid some problems that the difference in surface structure may cause.
Brush the wall with a roller brush
The roller brush, also known as a roller, is a roller brush that needs to be used with a paint tray. Because of the wide range of rolling surfaces, it is the most labour-saving and time-saving brush tool, especially when connected to an extension pole and can easily paint high walls or ceilings. Still, the disadvantage is that it is easy to produce paint splashes.
The roller brush is divided into long, medium and short hairs, which is the length of the roller fabric, not the thickness and length of the roller itself. The long-haired roller will paint some fine texture, with a sense of bump, similar to the texture effect. The short-haired roller is more even and smooth, with no bumpiness, and the medium-haired one is in between.
The brush hair is usually divided into wool and chemical fibre type two. Roller brush is mainly made of wool, and foam can be divided into paint roller brush, brushed roller brush, floor paint roller brush, flat roller brush, etc., mainly used for building decoration projects of a large area paint roller. And can be used to roll various blending paint, such as latex paint, rust-proof paint, interior and exterior wall coatings, wallpaper laminating glue, etc.
Use a bristles paint brush to brush the wall
Paintbrush is generally divided into pig bristles paint brush and wool brush. Pig bristle paint brush, also called pig bristle brush, refers to the brush made of bristles grown on the neck and back of the pig, usually more than 5cm; pig bristles are stiff, flexible, not easy to deform, moisture resistant, high temperature resistant, not affected by heat and cold, especially for the relatively high concentration of paint and glue.
The wool brush is fine soft, and smooth, levelling, paint content, levelling, can even spit out the paint so that the surface of the paint is smooth and consistent in thickness, not easy to leave brush lines and bristles on the painted surface, smooth construction hand, durable and other characteristics. The disadvantage is that it is easy to lose hair. So use your hand to move on the paintbrush head before using it to clean the losing bristles.

If you need to dilute, you must also follow the proportion of product instructions to dilute.
