TL;DR
Surface preparation is the combined cleaning, scraping, sanding, patching, degreasing, and priming done to a substrate before paint or coatings go on. On exteriors it often starts with washing off chalk and mildew, then feathering failed edges and spot-priming bare wood or rusted metal.
What it means
Surface preparation is the combined cleaning, scraping, sanding, patching, degreasing, and priming done to a substrate before paint or coatings go on. On exteriors it often starts with washing off chalk and mildew, then feathering failed edges and spot-priming bare wood or rusted metal. Coating manufacturers void warranties over skipped prep, and the majority of peeling and blistering failures trace back to this stage rather than to the paint itself.
