3. Describe the difference between zero VOC and low VOC paints.
Zero VOC paints contain 5 gm/liter or less of VOCs, while low VOC
paints contain 50 gm/liter or less.
Zero VOC paints have no VOCs, and low VOC paints have a higher
limit of 100 gm/liter.
, Zero VOC paints are made from synthetic materials, while low VOC
paints are made from natural materials.
Zero VOC paints are more expensive than low VOC paints.
