Rough paint surface – how to maintain it

The newly painted surface is rough, usually due to unclean paint brushes or pollution from the surrounding environment. It is also possible that there is a mixture of paint skin in the paint that has not been precipitated and filtered before use, or that the paint has become dusty when it is not dry.

To prevent the above problems, clean paint brushes and barrels must be used. Before using old paint, be sure to filter it with paint filter paper or clean nylon stockings.

In addition, the painted surface should be covered with a cover or cardboard before the paint is dry to prevent dust from getting on. If the paint surface is rough, wait for it to dry thoroughly, use dry and wet sandpaper to polish it smooth, wipe it clean, and then reapply the paint.

Special attention should be paid to the cleanliness of the paint brush.
