What Is Alkyd Enamel?

Alkyd enamel is a paint made for various interior or exterior surfaces, such as wallpaper, plaster, wrought iron, brick and aluminum, according to Behr. Painters can apply the product to cabinets, trim, doors and molding, but it is not intended to be used on surfaces on which people walk.

The traditional alkyd enamel is an oil-based paint that flows easily whether the painter applies it with a roller or brush. The paint produces a hard, smooth finish that makes surface imperfections less noticeable and is durable in high-use areas, according to Sherwin-Williams. Manufacturers offer alkyd enamel in finishes such as glossy for a wet look, semi-gloss, and for less luster, a satin finish, note Valspar and Behr.
