The more we write about paints the angrier we get. The government does not require manufacturers to print the total contents of their product on the label of the can. He is only required to list chemical contents that may be hazardous to health.

Oil paint for example, is basically linseed oil (or some other vegetable oil) mixed with a metal byproduct called a metal soap. When exposed to oxygen in a thin layer the linseed oil and metal soap combine, dry and become basic varnish. A solvent such as turpentine is also used to reduce the viscosity of the linseed oil, making the varnish thinner and easier to apply. Finally, the addition of pigment and fillers give color and body. This is when the basic varnish becomes paint.

One of the more popular materials used to make good quality paint is titanium dioxide. But it is expensive and many manufactures dilute it with clay fillers that don't hold up as well as the titanium.

Bottom line: Until there is legislation that forces paint manufacturers to list the contents on the can (by volume) we're all in the dark. Unless you purchase the top-line product you might be disappointed.

For stucco, we advise a latex paint. The sheen selected should be subject to your taste. Semi-gloss is fine. The number of coats depends on the existing and new colors. Matching the existing color is the best way of keeping the number of coats required to a minimum. Covering a dark color with a light color could require as many as three coats.

When contracting with a painter who claims that one coat is all that is needed, be sure to insist that he guarantee his claim in writing by stating that the price of the contract includes complete coverage.

Acrylic latex paint over an oil primer is great for wood trim that was previously painted with oil-based paint. Latex paint oxidizes as readily as oil base paint, but in the darker colors doesn't chalk like oil-base. So, it is important to use latex if darker colors are being considered.
