COMBINE WITH REAL MILK PAINT® FOR OUTDOOR PROJECTS
“Outdoor Additive” by The Real Milk Paint Company is an exterior paint additive made with 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 painting furniture project 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 paints. The paint would need to be removed first. Real 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 paints are supposed to work.
Now Real Milk Paint® can be used on your outdoor projects. Having an old house built in 1892 with original wood clapboard siding and windows, I wanted to use a period-appropriate paint for the restoration. 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.
