          2, brush marks the main reason

          Water-based paint viscosity is too high, too fast evaporation of water.

          In the wood products brushing, there is no parallel grain direction parallel operation.

          The brushes used are too small or the bristles are too strong or the brushes are poorly kept to make the bristles uneven or dry.

          3, to solve the problem

          Adjust the viscosity of water-based paint.

          Brush construction, should be the first direction along the wood grain over the water paint paint brush.

          To use a softer oil brush, oil to light action. Brush with oil, the application of thinner wash and keep safe, brush the missing brush should not try.

          A one-time brush water paint area not too large;
