Brush used for base treatment of high-grade wooden staircase handrails

Brushes are also used for the base treatment of high-end wooden staircase handrails. High grade wooden staircase handrails often require paint backing, nitrocellulose wood varnish or polyurethane varnish for polishing and decoration. Therefore, when dealing with their appearance, it is necessary to first use a 100 grit sandcloth to roll the flat wood board and repeatedly polish it along the wood grain until it is smooth and even. Then, use a 120 grit sandcloth to roll the wood board and vigorously polish it along the wood grain until the surface reaches a very smooth and even finish.
For the edges and curved areas, it is even more important to carefully press and polish the noisy cloth repeatedly until it feels unstoppable. When encountering exposed nail covers with hanging hands, a steel hammer can be used to nail them into the wood at a depth of 0.2-0.3mm. However, it is not allowed to directly hit the cover with an iron hammer to prevent leaving hammer marks that may affect the aesthetics of the coating. All operations are polished and qualified
Afterwards, first use a brush to clean the floating powder, and then repeatedly wipe it with a damp cloth.
