What Paint Preparation Means
Paint preparation is the work completed before coating, including cleaning, repairs, sanding, scraping, caulking, masking, and priming where needed.
Where It Is Commonly Used
Preparation is required on walls, ceilings, trim, cabinets, siding, and other surfaces whenever defects, contamination, gloss, damage, or failed coatings could affect the result.
Benefits
Good preparation improves adhesion, appearance, durability, and consistency. It reduces the chance that stains, peeling edges, cracks, or surface defects will show through the new finish.
Important Considerations
The correct preparation depends on the material and existing condition. Rushing this stage may produce a quick visual change but usually shortens the life of the finished work.
