8 2 With a lesser role, but with an equally important mission, the paint rollers. For water or solvent-based enamel and varnishes, choose the specific paint roller for each application. They are available in a number of dimensions and they can be made of mohair, velour, or polyester sponge. All brand-named paint rollers have the ability to accept replacement cartridges. Wash all new rollers with lukewarm water before use. Do not leave the used rollers with paint or varnish for a long time during your breaks. You can wrap them in a plastic bag so that you do not wash them every time you stop your work, after you have removed the bulk of the paint/varnish material from them. The roller should apply a uniform coat of paint or varnish, without splashing or running on the surfaces. When your project is completed, wash them with plenty of water until all traces of paint or varnish are removed. The above information applies to rollers used with water-soluble products. Rollers used for applying varnishes and other solvent-based products are more difficult to clean. It is easier to replace the used painting cartridge with a new one (paint rollers are cheaper than the actual solvent) and thus save yourself from the painful cleaning procedure with the solvent. Any varnish or paint left on the container can be reused, even after a period if the container is hermetically sealed, turned upside down, and stored indoors, away from direct sun or frost exposure.
