Which is better latex or water based paint?
Water-based paints, such as latex and acrylics, are desirable because they are much safer and dry much faster than oil-based paints and do not require toxic solvents for cleanup. While water-based paints are durable, they last longer if properly protected with a finish, such as varnish. However, not all varnishes are suitable for a project.
