Brush Coating

When interior pipe surfaces are rough, scaled, or pitted—but a full replacement isn’t practical—brush coating can be a smart, minimally invasive repair. John Shelton Plumbing applies professional brush-on epoxy or polymer coatings to rehabilitate short sewer segments, transitions, and fittings. It’s a precise, surface-renewal method that improves flow, seals small defects, and extends pipe life—all with limited access and minimal disruption to your property.

What Is Brush Coating?

Brush coating is a sectional rehabilitation technique where we clean the pipe interior and apply a specialized coating to rebuild a smooth, protective surface. Unlike full-length liners used in Trenchless Pipe Lining, brush coating targets shorter areas—elbows, wyes, transitions, or sections with heavy scale—making it ideal when a small zone needs attention.

When Brush Coating Makes Sense

• Scaled cast iron: Restore flow and reduce snag points that catch debris.
• Minor corrosion and pitting: Seal small defects to slow deterioration.
• Transitions & fittings: Treat complex shapes where liners are difficult.
• Pre-liner prep: Smooth rough sections to support a clean liner install.

Our Brush Coating Process

1) Inspection & Cleaning

We begin with a Sewer Camera Inspection to evaluate the pipe’s condition and determine if brush coating or a full liner is the right fix. Then we perform Hydro Jetting and descaling to create a clean, bondable surface.

2) Masking & Protection

We protect nearby fixtures and stages so coatings go exactly where they should—no drips, no overspread.

3) Controlled Application

Using specialized brush systems, we apply one or more coats to rebuild a smooth interior. We work carefully through bends and fittings, ensuring even coverage and proper thickness.

4) Cure & Verification

After curing, we re-inspect with the camera to verify coverage and flow improvements. Where necessary, we add a final pass to perfect the surface.

Benefits of Professional Brush Coating

• Minimal access required: Work is performed via cleanouts with limited opening of finished areas.
• Improved flow: A smoother interior reduces friction and clog potential.
• Targeted and efficient: Focus on the exact trouble spot without lining entire runs.
• Budget-friendly: Often less costly than excavation or full-length liners for spot issues.

Brush Coating vs. Trenchless Lining

Both methods are “no-dig” solutions but serve different needs. Brush coating is best for localized defects, fittings, or scale removal and resurfacing; trenchless lining rehabilitates longer runs and structurally reinforces deteriorated pipe. We’ll show camera footage and recommend the right option—sometimes a combination delivers the best result.

FAQs

How long does brush coating last?

Service life varies with pipe condition and usage. With proper cleaning and application, coatings provide durable protection and smoother flow for years.

Is brush coating safe for cast iron and PVC?

Yes. We select compatible coating systems for the pipe material and environment, and we verify adhesion with post-cure camera checks.

Will there be strong odors?

Any application odors are temporary. We ventilate as needed and schedule work to minimize disruption to your home or business.
