Best Interior Paint Brush for Walls and Perfect Cut-Ins

The Idaho Painter’s Go-To Brushes for Professional Results

If you’ve ever struggled to get clean cut-ins or smooth brush strokes on interior walls, you already know this truth: your brush matters just as much as your skill.

 

What’s up — Chris, The Idaho Painter, here. I get asked all the time across social media:
“What’s the best interior paint brush for walls and cut-ins?”

 

After decades of painting interiors and testing just about every brush out there, I’m breaking down the exact brushes I trust and why they work — especially with today’s thicker paints.

 

All of these brushes are handcrafted in New York, USA by Premier Paint Roller Company, a family-owned company with over 57 years of experience, and you can buy them exclusively from Paint Life Supply Co., the family-owned tool store by The Idaho Painter.

Why Brush Quality Matters More Than Ever

Modern interior paints are thicker, heavier, and loaded with fast-drying additives. That means:

• Cheap brushes lose stiffness fast

• Soft filaments struggle to cut straight lines

• Poor-quality handles cause hand fatigue

• Low-end filaments absorb water and get floppy

 

That’s why I only use Premier’s professional line. These brushes are handcrafted, consistently built, and use the best filaments in the world — including DuPont filaments, which outperform standard nylon and polyester in every way.

Premier Paint Brushes — Handcrafted in the USA

Premier Paint Roller & Brush Company is based in New York, and their professional brushes are:

• Handcrafted by skilled craftspeople

• Built with premium wood handles

• Fitted with stainless steel ferrules (no rust)

• Made using top-tier filaments, including DuPont

 

I’ve toured the factory, met the owners, and watched how these brushes are made. The quality is real — and consistent.

The Best Interior Paint Brush for Cut-Ins: The Premier Brooke

If I could only choose one interior paint brush, this would be it.

🏆 The Premier Brooke Paint Brush

Designed by The Idaho Painter — Exclusive to Paint Life Supply Co.

 

I worked directly with Premier and Kevin Leichter (the owner) to design this brush exactly how I wanted it. It’s named after my older daughter, Brooke, and it’s the brush I reach for when I need perfect cut-ins.

 

Why the Brooke is my favorite for walls and cut-ins:

• Firm DuPont filament blend (Tynex + Orel)

• Holds stiffness longer while painting

• Cuts razor-straight lines at ceilings, doors, and trim

• Works with all interior paints and stains

• Stainless steel ferrule won’t rust

• Comfortable, balanced handle for all-day use

• If consistency matters on interior and exteriors this is the one

 

Today’s thicker wall paints demand a firm brush, and the Brooke delivers. Whether you’re cutting ceiling lines, door jambs, or window trim, this brush gives you maximum control.

 

Pro Tip:
I recommend a 3-inch angled sash. It holds more paint and lets you cut farther without reloading — once I switched from a 2½-inch brush, I never went back.

Best Brush for Interior Trim: The Premier Hampton

🎯 Premier Hampton Paint Brush

The Hampton is handcrafted with 100% DuPont Tynex filaments, but it’s noticeably softer than the Brook.

 

That softness makes it ideal for interior trim, especially when using thinner trim paints.

 

Why I use the Hampton for trim:

• Softer filament reduces paint roping

• Perfect for door jambs, window sills, and casing

• Excellent with low-viscosity trim paints

• Smooth finish with fewer brush marks

• Consistently perform like a professional brush should

 

If you’re brushing trim all day, a softer brush like the Hampton helps paint lay down cleaner — especially with thinner enamels.

Best Budget Interior Brush That Still Performs: The Premier Malibu

💰 Premier Malibu Paint Brush

If you want Premier quality but need to save some money, the Malibu is an outstanding option.

 

It uses Premier’s nylon/polyester blend (not DuPont), but don’t let that fool you — it still performs extremely well.

 

Why the Malibu is worth it:

• Great stiffness for walls and trim

• Excellent with modern latex paints

• Same premium handle and ferrule as higher-end brushes

• If brushes get abused on job sites this is a great option

 

I tested the Malibu while brushing and rolling an entire 1950s remodel using Benjamin Moore Advance, and it performed amazingly well — especially since Advance is a thicker paint.

For painters who brush Advance or Emerald Urethane this is the perfect option.
