Our Lightweight Spackle is ultra low-VOC and virtually odorless to promote healthier indoor air quality. Our low-VOC paint meets the strictest standards in the industry, currently set by California's South Coast Air Quality Management District (AQMD). The EPA says that indoor air can be ten times more polluted than the air outside, so using low-VOC paint is one way of improving indoor air quality. Our VOC paint doesn't only promote healthier living, but also improves our environment by reducing emissions. Luckily with Soto, you never have to sacrifice performance, as all of our products, including our Lightweight Spackle, are exceptionally durable. It's an interior + exterior rated, ultra opaque paint and primer in one, so only two coats are required.
