First thing to know about acrylic paint… it dries pretty quickly! so you have limited "working" time when blending.
Ferrule: Metal part of the paintbrush that holds the bristles together – no paint here!
Water: Keep it clean! Avoid muddy colors [and use a paint cloth]
Colour mixing - its science and maths! its ratios/proportions and uses chemicals!
Value: Lightness or darkness of any hue [colour]
Acrylic paint dries very fast. To preserve the health of your paintbrushes it is extremely important to:
Keep the bristles moist at all times while painting.
Clean brushes promptly at the end of each painting session.
During your acrylic painting session, make sure to rinse any residual paint from your brushes before putting them down and keep them wet just in case there is any unseen residue of paint near the ferrule, you don't want it to dry, or your bristles will spread out and lose their shape.
When you change colour paint or you switch to another brush, remove any excess paint with a paper towel or paint cloth and rinse the brush thoroughly, then lay the wet brush flat until you need it again.
its not rocket science but its important!
Remove most of the paint from your brushes in your water jar and using a paint cloth.
At the sink rinse and rub the brush to remove paint [if there is a makeup brush mat in your clasroom sink - use that to scrub the bristles under running water.
Use soap if needed to remove paint, but its seldom needed!
squeeze bristles and repeat until water is clear.
Dry excess water with a rag, being gentle on the bristles.
Once dry, store your brushes flat or bristle-up, to avoid bending of the hairs.
Clean up your space... its easier to clean up wet paint then dry acrylic paint!
