Add to milk paint to create a durable exterior, all-natural paint. Outdoor Additive boasts in its ability to reduce tannin’s leaching through milk paint from wood knots and discoloring the surface. It also provides improved resistance to mold and mildew growth.
▫ “Outdoor Additive” by The Real Milk Paint Company is a borate compound, similar to borax. Borax can be found at the grocery store as Twenty Mule Laundry Booster. It is mined from the ground mainly in California. Borax is safe and non-toxic and has multiple uses. “Outdoor Additive” is a slightly modified borax compound that is very finely milled, so that when added to the paint it remains smooth.
▫ Real Milk Paint® with “Outdoor Additive” is suitable for exterior porous surfaces such as wood, concrete, brick, and stucco. It should not be used over existing paint. Milk Paint with “Outdoor Additive” will not blister and peel like modern paint but will act as a sacrificial coating that will gently wear away with time. The way paint is supposed to work.
▫ While milk paint does work well outdoors as is, adding “Outdoor Additive” makes the paint even more superior and is one of the best wood finishing products that you can use.
▫ For enhanced exterior use and improved water resistance, topcoat Real Milk Paint® with Outdoor Defense Oil (for more information you can check out our Outdoor Defense Oil listing).
▫ Tannin Stain Blocker – blocks stains from coming through the paint on woods such as cedar and knotty pine.
▫ U.V. light protection – inhibits ultraviolet light from destabilizing the paint film.
