Paint roller covers vary in their composition, density, nap, and application.
Foam roller covers are best for applying gloss or semi-gloss paints, and leave no lint or stipple behind. Water-based and solvent-based adhesives and epoxies work better with synthetic rollers that have a short 1/8 inch nap and a smooth surface. Polyurethane foam roller covers work well with paint, varnish, and epoxy.
