Surface Preparation for Painting
Attractive and long-wearing paint finishes are not possible without proper surface preparation. Paints and coatings are chemicals that must properly bond to the substrate to adhere smoothly and durably. Painting a dirty, corroded, or peeling substrate might be a short-term improvement, but the finish will be uneven and the paint adhesion will quickly fail.
At McCahill Painting, we’re meticulous about our prep work, a key reason our finishes are both beautiful and highly resilient. We’re experts at safely removing old paint and other contaminants to restore surfaces to their original composition before painting and encourage optimum paint adhesion.


Surface Preparation Techniques
With 40+ years of experience, we know which surface preparation techniques and priming products work best on each substrate type (metal, steel, concrete, wood, drywall, brick, stone, etc.). We customize our exact methods to each project to ensure the surface is prepped but never damaged, and we always consider the work environment to minimize dust, mess, and disruption.
Our surface preparation techniques:
- Sanding
- Grinding
- Hand scraping
- Abrasive blasting, including vapor blasting, Sponge-Jet® blasting, sandblasting, and soda blasting
- Power washing, including gentle yet highly effective hot water power washing
- Rust removal and control
- Caulk and joint repair
- Tuckpointing repair
- Sealing and waterproofing
- Priming, with professional-grade primers applied per manufacturer specifications
- Masking, to carefully protect areas not to be painted
