DIY Guide: Painting Window Frames Black – My Hands-On Renovation Experience

As a seasoned DIY enthusiast who's tackled numerous home renovation projects, I know the satisfaction of saving money by doing the work myself. While outsourcing is tempting, especially for time-intensive tasks like painting window frames, rolling up my sleeves allows me to prioritize my wishlist faster. Today, I'm sharing my real-world experience painting the frames on over 20 windows black.

Of course, hiring a professional saves time, but with the right preparation and materials, you can achieve professional results at home. Here's my step-by-step journey.

Painting Your Own Window Frames at Home

Most homeowners handle wall painting with ease, and I've found an excellent one-coat coverage paint that makes it effortless. But window frames? That's a bigger challenge many leave to pros. With proper prep and quality paint, I've successfully done it myself.

Paint the Brown Lacquered Frames Black

Our home's windows, shutters, stable doors, interior doors, sliding doors, and stairs feature outdated brown lacquer. To modernize, I'm painting the exterior and interior frames black. The stairs and doors might get a steel-look upgrade later, and that ceiling is next!

Black looks stunning but absorbs heat, potentially shortening paint life—something painters warned about. Still, we're proceeding inside and out. The paint I've selected resists yellowing effectively.

Painting the Interior Frames Yourself

A glazier recommended Allgrund primer for minimal sanding, but its overpowering odor lingered for weeks after a test. Not ideal for the whole house.

After researching and consulting a paint specialist, I chose Sigma S2U Nova Satin over Sigma S2U Nova Primer. This water-based, odorless, eco-friendly system is perfect.

Here's the proven treatment plan:

How to Paint Your Own Window Frames

  1. Degrease woodwork
  2. Rinse woodwork with clean water
  3. Sand woodwork (bare is not necessary), first with grit P180 and then with grit P240
  4. Make woodwork dust-free
  5. Apply 1 coat of Sigma S2U Nova Primer
  6. Matt the intermediate layer with Siavlies sponge
  7. Apply the first coat of Sigma S2U Nova Satin
  8. Matting intermediate layer
  9. Apply a second coat of Sigma S2U Nova Satin

Tape walls, hinges, and locks beforehand for crisp lines. Remove tape before full drying.

Allow two weeks for full curing—it's dust-dry in 1 hour, tack-free in 3, recoatable in 5, but handle gently.

This plan means steady progress on my home, including potential interior doors. I'll pace myself, tackling one frame at a time and storing brushes in thinned paint to avoid constant cleaning.

P.S. I degrease the window frames with Monastery Pride, a 98% biodegradable, eco-friendly alternative to ammonia. Ideal for all grime types!

Painting the Exterior Frames Yourself

Exterior work matches the interior effort, including hatches. I can't wait—the black frames will dramatically modernize our look.

Success hinges on prep, quality paint, and precision. Avoid rain or direct sun; work methodically, not rushed.

What Paint Do You Use for Exterior Painting

Sigma S2U Nova is interior-only, so for outside, Sigma S2U Allure (Gloss or Satin) is turpentine-based and durable. Gloss offers maximum strength, crucial for black. I'll start indoors, then exteriors when weather cooperates.
