Latex paint is considered a non-hazardous material and can be disposed of similar to other household waste.

Latex based paints are offered in a variety of finishes, including gloss, semi-gloss, and satin finishes.

Latex based Paint Disadvantages

Latex based paints are ideal for non-high traffic areas, e.g. dining rooms, living rooms, or home exteriors.
