Using the handbrake

This tool is characterized by a round shape. A metal rim connects the bristles to the handle. It is the length of the handle that is an important factor for successful work with the tool. The pile length may be more or less short. When using a brush with too long bristles, rubber wrapping is practiced. This simple technique will help in reducing the area of ​​the bristles. Then the paint will be applied more precisely, not smudged.

Expert advice

Most people have to economically manage their resources using old tools. This cannot be called the correct method. Such savings are not rational, as it takes a lot of time and effort.
