Lapping

Appearance of a denser color or increased gloss where wet and dry layers overlap during paint application.

Possible Causes

• Failure to maintain a "wet edge" during application
• The use of low-grade, low-solids paint
• Applying finish coat to an unprimed, porous surface

Recommendations

• ** See Lead Information for warnings.
• Always maintain a wet edge when painting by starting in an unpainted area and then paint from "wet to dry".
• If the substrate is very porous, apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer. This will help prevent the finish coat from drying too quickly and reducing wet edge time.
• Apply 1-2 coats of Accolade® Paint + Primer. The high solids content of this premium finish will make lap marks less likely.

**Lead Information

Removal of old paint by sanding, scraping, or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment, such as properly fitted respirator (NIOSH-approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in U.S.) or contact your local health authority.
