How to Prepare for Commercial Exterior Painting in Boise

April 11, 2025

What Boise business owners need to know before starting an exterior painting project

A fresh coat of paint does more than improve your building’s appearance—it protects your property, reinforces your brand, and shows customers you take pride in your business. But before the first drop of paint goes up, there’s work to be done. Proper prep is what separates a paint job that lasts for years from one that fades or fails prematurely.

At Spray ’n Coat Painting, we help Boise-area businesses prepare for commercial exterior painting the right way. Whether you’re in Boise, Meridian, Eagle, or Nampa, here’s what to expect before painting begins.

Step 1: Schedule an On-Site Walkthrough

Every successful project starts with a detailed walkthrough. Our team meets with you onsite to:

Inspect for peeling paint, cracks, stains, or structural damage
Identify maintenance issues that could affect paint performance
Recommend repairs or refer trusted contractors if needed

This upfront assessment ensures nothing gets overlooked—and that your property is paint-ready before we even begin.

Step 2: Handle Repairs Before Painting

If our walkthrough uncovers any damage, now’s the time to address it. Common repairs include:

Replacing rotted trim or siding
Patching stucco or masonry
Treating rust on metal surfaces
Sealing cracks around windows or doors

These fixes protect your building and ensure the paint properly adheres to every surface.

Step 3: Power Wash All Exterior Surfaces

Clean surfaces are essential for paint to bond and last. That’s why we recommend a full pressure wash to:

Remove dirt, mildew, and peeling paint
Treat mold with commercial-grade cleaners
Ensure all surfaces are completely dry before prep

Skipping this step risks poor adhesion and a finish that won’t hold up.

Step 4: Protect Landscaping and Fixtures

Exterior painting isn’t just about the walls—it’s about protecting everything around them. Before painting, we take steps to safeguard:

Windows, trim, signs, and fixtures with sheeting or masking
Nearby landscaping or outdoor furniture
Vehicles or equipment that could be impacted by overspray

We also recommend trimming any trees or bushes that may block access or coverage.

Step 5: Choose the Right Paint and Colors

We help guide the process, but for final color choices, we refer our customers to color experts at Sherwin-Williams or similar suppliers.

Important considerations include:

Paint formulated for Boise’s freeze-thaw cycles, UV exposure, and rain
Low-VOC or fast-drying paints for businesses with high customer traffic
Colors that align with your branding and help your property stand out

Choosing high-performance, commercial-grade paint sets the stage for lasting results.

Step 6: Prime and Prep for Maximum Durability

Surface prep is one of the most important steps. Our team ensures:

Loose or flaking paint is scraped off
Rough areas are sanded smooth
Primer is applied where needed for proper bonding and protection

The result? A clean, stable surface ready to accept paint—and one that resists peeling, cracking, and fading.

Step 7: Schedule Painting to Minimize Disruptions

We understand that your business needs to stay open. That’s why we offer:

Flexible scheduling, including weekends or off-hours
Quick-drying products for minimal downtime
A clear project timeline so you can plan ahead

We work around your operations to keep things running smoothly from start to finish.

Step 8: Final Walkthrough and Quality Inspection

Before wrapping up, we conduct a detailed walkthrough to ensure:

Uniform, professional coverage with crisp lines
Clean finishes on all trim, doors, and accent areas
Surfaces are fully dry and ready to use

We don’t just meet expectations—we check our work to make sure we exceed them.
