Exterior Painting and Staining
Professional painters spend more time preparing surfaces than applying paint. Homeowners who don't understand this often focus on colour selection while neglecting the preparation that determines job success.
Power washing is the starting point for most exterior paint preparation. Removing dirt, loose paint, algae, and chalk creates a clean surface that allows paint to bond. The surface must dry completely before proceeding.
Preparation Is Everything
Scraping removes all loose and peeling paint. Attempting to paint over loose paint creates a new coat that peels almost immediately. Every area of adhesion failure must be scraped to sound paint or bare substrate.
Sanding feathers the edges of paint removal areas, creating a smooth transition between bare areas and surrounding intact paint. Unpainted feathering creates ridges visible through new paint.
Long-Lasting Results
Priming exposed bare wood and metal is essential before topcoat application. Primer creates adhesion, seals porous surfaces, and provides a base that topcoats can bond to. Skipping primer is a false economy.
Caulking all joints, gaps, and transitions before painting seals water entry points. Paintable exterior caulk applied after priming and before topcoating adheres better than caulk applied after painting.
Masking and surface protection protect adjacent surfaces — windows, plants, walkways — from paint overspray and drips. Professional painters use painter's tape, plastic sheeting, and drop cloths to protect what shouldn't be painted.
