Surface Prep: The Key to a Long-Lasting Paint Job
Proper surface prep is the foundation of any great paint job. At Big Dog Painting, we believe that taking the time to prepare surfaces thoroughly - whether interior or exterior - can make the difference between a short-term fix and a lasting transformation. We’ll walk through the most important steps of painting surface preparation, explain how pressure washing plays a role, and show you how to prepare a painted surface for repainting the right way.
Why Surface Prep Matters
If you want a smooth, durable finish, you need to start with the right foundation. Surface prep isn’t just a good idea - it’s essential. Failing to properly prepare surfaces can lead to poor paint adhesion, peeling, and a shorter lifespan for your paint job. Whether it’s an interior wall or your home’s exterior siding, investing in high-quality preparation pays off.
How to Prepare Surface for Painting
The first step in painting surface preparation is cleaning. Dirt, grease, mildew, and old paint all interfere with how well new paint sticks. That’s why we often recommend pressure washing before painting for exterior surfaces. This removes contaminants and gives us a clean slate to work with.
Next comes scraping, sanding, and patching. Any peeling or cracked paint must be removed, and holes or surface imperfections need to be filled and smoothed. On interiors, this may include sanding down glossy finishes or repairing drywall. On exteriors, it might involve replacing damaged wood or siding - services we often handle through our carpentry team.
Surface Preparation for Painting: Step by Step
Every project is unique, but here’s a simplified version of our general approach:
1. Clean the surface thoroughly (often with pressure washing)
2. Scrape away loose paint
3. Sand and smooth rough spots
4. Repair any damage
5. Prime the surface if needed (especially for bare wood or stains)
These steps ensure the new paint bonds properly and creates a smooth, even appearance that lasts. Skipping any of them can lead to bubbling, cracking, or early fading
How to Prepare a Painted Surface for Repainting
Repainting is more than just adding a fresh coat. If the existing paint is in good condition, sometimes light sanding and cleaning may be enough. But if the surface shows signs of wear, flaking, or water damage, more extensive prep is necessary. We assess each project individually to determine exactly what your home or business needs before any new paint goes on.

Frequently Asked Questions
What is surface prep in painting?
Surface prep is the process of cleaning, repairing, and priming a surface before applying paint. It ensures proper adhesion and a smooth, long-lasting finish.

Pressure washing removes dirt, mildew, and old paint, creating a clean surface for the new paint to bond to. It's especially important for exterior painting jobs.
How do you prepare a painted surface for repainting?
To prepare a painted surface for repainting, clean it thoroughly, scrape off any loose or peeling paint, sand glossy areas, repair imperfections, and apply primer if necessary.
