Foaming/Cratering

The formation of bubbles that may break and result in craters during the application and drying process.

Possible Causes

• Over application of product (rolling too rapidly)
• The use of a low-grade or old paint
• Over shaking the paint prior to painting
• Applicator did not use the recommended roller cover nap length.
• Finish coat was applied over an unprimed, porous surface.

Recommendations

• **See Lead Information for warnings.
• Problem areas should be sanded smooth prior to repainting.
• Apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer to seal any porous surfaces.
• Avoid excessive rolling or brushing during application.
• Follow recommended application procedures and use appropriate roller cover nap sizes.
• Apply 1-2 coats of Accolade® Interior Paint + Primer. Accolade® was specifcally formulated to provide superior flow/leveling, which lessens the potential of bubbling occurring.

**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.
