What is the best acrylic powder to do intricate roses with (a powder that does not get hard quickly)? Also, what’s the best type of acrylic brush to do these intricate designs?
Choose a powder with high-quality pigments. You can tell it has high-quality pigments if, when you place a bead of acrylic, it is smooth and creamy and sets up like the texture of marshmallow. The pigment should not separate from the polymer when it is wet. The working time depends on the technician. More experienced technicians like to work faster, so they add some acetone into the monomer to speed up the working time. To get a fine finish and clarity on 3-D work, it has a lot to do with your application, product control, and brush angles.
The best brush to use for flowers would be a flat oval size 6 Kolinsky brush that snaps to a point.
