11/19/2023 0 Comments Cleaning a paintbrushConversely, do not use bristle brushes with waterborne paints - they will water-log and perform badly.īristle brushes are readily available, in any quality from cheap Indonesian chip brushes to badger brushes like your great great grandfather used. However "normal" synthetic brushes will not perform well with alkyd paints - with alkyds, use natural-bristle brushes. "Normal" hardware-store rollers can be used with alkyd paints/primers like Kilz Original. If you have been using water to thin alkyd paint, that would only make it thicker still - and spoil it too! It really helps to use the right brush, though. I paint stuff I don't want til the brush goes dry, re-whet the brush in contaminated thinner, work that in, paint stuff again til the brush goes dry, re-whet, then use rags to soak the thinned paint out of the brush. I'm pretty good at cleaning brushes with just a couple of ounces of thinner. In the halcyon days of my youth before anyone knew better, we used to use 60 cent a gallon gasoline, of course disposal was an environmental nightmare even then. The Kilz label indicates using mineral spirits for cleanup that covers a wide variety of products including paint thinner, literal mineral spirits including odorless, etc. Los Angeles being the poster child for this their rules are far more draconian than everywhere else. VOCs are mineral solvents like gasoline that evaporate and cause regional smog. It says "Do Not Thin", because if you reduced it with paint thinner, the paint-in-pot would exceed the allowable VOC limits for some regional Air Quality Management District somewhere, and they don't know where you'll paint it. Now, Kilz Original is an alkyd (read: oil-based) paint. Some paints will recommend another chemical for cleanup if the reducer is too expensive. Whatever that "thinner" is, you can use that for cleanup solvent. The paint label will specify what to use for a reducer (aka "thinner" that makes the paint thinner). You just have to avoid higher-performance products like Kilz Original. That's wrong, but if you want that, it's perfectly possible to paint a house using entirely water-based products. These can be found at home centers, department stores, and grocery stores.You've made a leap of assumption that all architectural paint is water-based. Mauro used Scotch-Brite Heavy Duty Scouring Pads, manufactured by 3M. If that does not work, a scrub pad can be used to gently brush off residue. He recommends using warm water, a little bit of soap, and your fingers to try to clean the paintbrush off. Mauro suggests that the best way to clean a paintbrush is to be as gentle as possible. Most paintbrushes come in a cardboard cover that can be re-used. Once the brush is dry, put it back in its cover.To dry, dap the brush on a rag and spin the brush in your hands in the sink to spin any remaining water droplets off the brush. Be as gentle as possible to be sure the bristles aren’t damaged.
