What exactly is painting a trim?

Paint trim refers to the decorative finishing elements in a room, such as the baseboards, window casings, door frames, crown moldings, and chair rails. Trim is typically made from wood, MDF, or other composite materials, and it serves to cover gaps between surfaces and provide a clean, polished look. Painting trim is a popular way to update the look of a room and can be done in a variety of colors to match or complement the wall color. Trim is often painted a different color than the walls to create contrast and highlight architectural features. Painting your trim can be a simple yet effective way to give your living space a fresh and updated look without the expense of a full remodel.

Why should you paint the trim?

  1. Freshening up the look of a room: Painting trim can give a room a fresh, updated look without the expense and mess of a full renovation.
  2. Creating contrast: Painting trim in a contrasting color can highlight architectural features, such as crown molding, and make a room feel more visually interesting.
  3. Concealing imperfections: If your trim has scratches, dings, or other imperfections, painting it can help to hide these flaws and make your trim look new again.
  4. Protecting your trim: Painting your trim can help protect it from moisture and wear and tear, which can extend its lifespan and save you money in the long run.

Overall, painting your trim is an easy and cost-effective way to improve the look of your home and protect your investment. Whether you’re updating your style or simply giving your home a much-needed refresh, painting your trim is a great way to achieve your goals.

Trim Paint In Brief

Firstly, using epoxy resin to paint your trim gives a super smooth, durable and long-lasting finish that looks absolutely amazing. Unlike traditional paint, which can easily chip and peel, epoxy resin dries to a hard, glass-like finish that’s highly resistant to wear and tear. I’ve used it on my baseboards and door frames, and even in high-traffic areas, it still looks as good as new!

Another thing I love about using epoxy resin is that it’s so easy to apply. All you need is a brush and a roller, and you’re good to go. The resin is self-leveling, so it evens out on its own, leaving no brush marks or bubbles. Plus, it dries to a crystal-clear finish, which means it won’t yellow over time, giving your trim a lasting shine.

One tip I would offer is to prepare your surface well before painting. Make sure the trim is clean, dry, and free of any debris, dirt, or dust. This will ensure that the epoxy resin adheres properly and produces a smooth finish.

In terms of materials, I highly recommend using a high-quality epoxy resin that’s specifically formulated for painting. I personally use one that’s low VOC, which means it’s eco-friendly and safe to use indoors. You’ll also want to invest in a good brush and roller, as well as some painter’s tape to protect your walls and floors.

All in all, I can’t recommend using epoxy resin to paint your trim enough. It’s a game-changer in terms of durability, finish, and ease of use. Give it a try and let me know how it works for you!

How To Paint Trim Materials Comparison

  1. Paint: Traditional paint is the most commonly used ingredient for painting trim. It comes in a wide range of colors and finishes, from matte to glossy, and can be easily applied with a brush or roller. However, paint can be prone to chipping and peeling over time, especially in high-traffic areas.
  2. Epoxy resin: Epoxy resin is a two-part system that creates a hard, durable, and long-lasting finish. It’s self-leveling, which means it evens out on its own, and dries to a crystal-clear finish. Epoxy resin is highly resistant to wear and tear, making it ideal for high-traffic areas. However, it can be more difficult to apply than paint and requires careful mixing of the two components.
  3. Oil-based enamel: Oil-based enamel is a popular choice for trim because it dries to a hard, glossy finish that’s resistant to moisture and wear. It’s easy to apply with a brush or roller and comes in a range of colors. However, oil-based enamel can be more difficult to clean up and has a strong odor.
  4. Latex enamel: Latex enamel is similar to oil-based enamel but uses water as its base instead of oil. It’s low in VOCs, dries quickly, and has less of an odor than oil-based enamel. However, it’s not as durable as oil-based enamel and can be prone to chipping and peeling.

Overall, each ingredient has its pros and cons, and the best choice for you will depend on your personal preferences and the specific needs of your project. If you want a long-lasting, durable finish, epoxy resin or oil-based enamel may be the best choice. If you’re looking for something easy to apply with a low odor, latex enamel may be the way to go. Whatever you choose, make sure to follow the manufacturer’s instructions carefully and prepare your surface well to ensure a smooth, even finish.

Step by Step Instructions on How to Paint Trim

  1. Clean the surface: First, clean the surface of the trim to be painted. Use a damp cloth or sponge to wipe away dust and debris, and allow the surface to dry completely.
  2. Sand the surface: Sand the surface of the trim with fine-grit sandpaper or a sanding block to smooth out any rough spots or imperfections. Be sure to wipe away any sanding dust with a tack cloth or microfiber cloth.
  3. Apply painter’s tape: Apply painter’s tape to any areas adjacent to the trim that you want to protect from paint. Use a putty knife or scraper to ensure a tight seal between the tape and the surface.
  4. Apply primer (if necessary): If you’re painting over bare wood or a surface that has never been painted before, apply a coat of primer to ensure proper adhesion and a smooth finish. Allow the primer to dry completely before moving on to the next step.
  5. Apply paint or enamel: Apply a coat of paint or enamel to the trim using a paint brush or roller. Work in long, even strokes and try to avoid going over the same area too many times, as this can create streaks or uneven coverage. Allow the first coat to dry completely before applying a second coat, if necessary.
  6. Apply epoxy resin (if desired): If you want to add extra durability and a high-gloss finish to your trim, apply a coat of epoxy resin using a clean paint brush. Follow the manufacturer’s instructions carefully and be sure to work in a well-ventilated area.
  7. Remove painter’s tape: Once the paint or epoxy resin has dried completely, carefully remove the painter’s tape. Use a putty knife or scraper to prevent any peeling or chipping of the paint.
  8. Clean up: Finally, clean up any remaining materials using paint thinner or water, and dispose of them properly. Clean your brushes and rollers thoroughly to prevent them from hardening or becoming unusable.

By following these step-by-step instructions, you can achieve a professional-looking finish when painting your trim. Remember to take your time and prepare your surface well to ensure a smooth, even finish that will last for years to come.

How to Paint Trim


Can I paint trim without sanding it first?

While it’s possible to skip the sanding step, we strongly recommend sanding the surface of the trim to ensure a smooth and even finish. Sanding will help the paint adhere properly to the surface and prevent peeling or chipping.

Can I use regular paint for trim, or do I need a special type of paint?

While you can use regular paint for trim, we recommend using a paint that is specifically formulated for trim work. These types of paints are typically more durable and have a higher sheen, which can help your trim stand out and add visual interest to your space.

Do I need to use primer when painting trim?

It depends on the condition of your trim and the type of paint you’re using. If you’re painting over bare wood or a surface that has never been painted before, we recommend using a primer to ensure proper adhesion and a smooth finish. If you’re painting over an existing coat of paint, you may be able to skip the primer step.

What type of brush should I use to paint trim?

We recommend using a high-quality, synthetic bristle brush when painting trim. Look for a brush with a tapered or angled tip, which can help you achieve clean lines and precision when painting corners and edges.

How long should I wait between coats of paint or primer?

The drying time between coats will depend on the specific product you’re using, as well as the temperature and humidity in your space. Always consult the manufacturer’s instructions for specific drying times, and be sure to allow each coat to dry completely before applying the next.

Can I use epoxy resin on all types of trim?

While epoxy resin can be used on many types of trim, including wood, plastic, and metal, it’s important to ensure that the surface is clean and free of debris before applying the resin. Additionally, you should always consult the manufacturer’s instructions and use caution when working with any type of chemical product.
