- Put them in the Water-based paint for 3 minutes
- Take out them until there is no paint drips and weight the paint brush
- Paint on the Gypsum board until not smooth
- Weight the paint brush again
- 70% bristle mixture 30% common filament
- 50% bristle mixture 50% common filament
- 30% bristle mixture 70% common filament

Step 2: Put them in the Water-based Paint for 3 minutes and take out until no paint drops

Step 3: Weight the brush separately

Step 4: Paint on the Gypsum board until not smooth

Step 5: Weight the brush head after painting

The following are the Painting holding and Release Chart Comparing

Summary (Painting)
From the test and date, we found 70% bristle mixture 30% filament and 50% bristle mixture 50% filament is almost same painting holding and release. 30% bristle mixture 70% filament of painting holding and release is a little less than 50% bristle mixture 50% filament.
