How-To Tips: Exterior Surface Preparation

Preparation is the essential key to good-looking, long-lasting results. A properly prepared surface is clean, solid and dry and without cracks and imperfections. Follow the general guidelines below and refer to the product label for specific instructions. If further direction is needed, contact your nearest Rodda Paint store.

Caution: Before removing or sanding any paint, check to determine whether paint contains lead. Lead may be harmful. Do not remove or sand paint without contacting local health officials for information on lead paint testing and safety precautions.

Treat Structural Problems: Fix or replace splitting or rotting wood, cracks in masonry, missing caulk, popped nails or rusty metal.
Remove Loose Coatings: Scrape, sand or brush off any paint that is cracked, blistered or peeling. Sand and feather rough edges.
Clean the Surface: Wash off dirt, grease and paint chalk with a strong detergent and water. Rinse thoroughly with fresh water and let dry.
Surface Profile: Smooth surfaces may have to be abraded or etched to create an irregular surface profile. A good profile is slightly rough, similar in appearance to fine sandpaper. An irregular surface provides more surface for coatings to adhere to, and breaks surface tension on polished, smooth surfaces. This is a critical step for good coating adhesion.
