How to Paint the Trim of a Room

There are many ways on how to paint the trim of a room. Painting it white is a good choice if you want your room to have an updated look. You can also paint it black for a more modern feel or any color that matches your décor. It’s important to consider the condition of the walls and what type of finish does not clash with them before making this decision. 

How to Paint the Trim of a Room

Painting the trim in colors other than white will require extra prep work and priming and painting twice so that all surfaces are covered evenly, and there are no visible brush strokes. In this blog post, we will give step-by-step guidelines and some tips and tricks to paint a room’s trim.

Type of Paint You Can Use on Trim:

1)Water-based latex:

This type of paint is very flexible, making it your best bet for the trim. It allows to be scraped and sanded, does not yellow or crack, and gives a durable finish. Additionally, it is easy to clean up later if you make any mistakes (or have kids around!). One drawback is that water-based latex can take longer to dry (3-5 days, with an open room and good ventilation).

2) Oil-Based Paint:

Oil-based paints are high maintenance because they need time to dry. It can take more than a week for water-based latex, while oil-based may take one or two weeks. This type of paint is good for high traffic areas and gives a shiny finish. However, oil-based paints are not water-soluble, so it’s difficult to clean mistakes and make touchups.

3) Enamel:  

Another good option is to use enamels, which are water-based and oil-based paint mixed. This paint dries faster than oil-based paints but slower than water-based latex. It also gives a glossy finish like oil-based paint. However, cleaning this type of paint is hard.

4) Latex:  

Latex paints are good for wood trim, but be aware that they get damaged when exposed to light and high temperatures. This type of paint can yellow in time and chips off easily too. It is also difficult to clean up mistakes with latex paints.

Important Things You Need for Painting Trim:

  • Paint Brushes
  • Trim brush
  • Paint bucket
  • Safety equipment
  • Tray to collect excess paint
  • Paint Roller or Foam Roller
  • Paper towels

Steps To Follow: How to Paint the Trim of a Room

Step 1: Prepare The Room

This may seem like an obvious step, but it’s important to clean your walls and have a fresh coat of primer on them before painting the trim. You do not want excess paint dripping onto your walls and causing stains.

Step 2: Remove The Moldings 

You will need to remove any molding from the room before you can start painting process. Use a hammer and chisel or paint chisel to pry off heavy moldings. You can use a sanding block for thinner ones.

Step 3: Clean The Paint Tray

Keep your work area clean by putting all the excess paint tray lined with a paper towel so that it will not spill onto the floor while you paint.

Step 4: Fill The Nail Holes

You will need to fill the nail holes so that they are less noticeable. You can do this by using wood putty knife and then sanding it down. Do not forget to wipe down your walls with a damp cloth before you paint the trim, to remove dirt and dust.

Step 5: Sanding The Trim

Use 120 grit sandpaper to ensure the area has smoothest finish before you paint it. This will help your paint to adhere better so that there are no visible brush stroke. Sand in the direction of the wood grain and not against it.

Step 6: Primer Your Walls

Apply a layer of primer to the walls and let it dry for an hour or two. Before applying primer to painted walls, make sure that they have been thoroughly cleaned and dried out. For best results, apply in thin layers rather than one thick coat to avoid drips. Depending on your painting trim, you may need to apply 2 coats of primer before painting.

Step 7: Caulk The Gaps

Using caulk, fill in the holes and cracks of the walls. Be sure to wipe your wall clean before you put on a fresh coat of caulk. Also, make sure that your caulking is dry before using it to paint, or else your brush marks will get messed up with excess caulking.

Step 8: Paint The Trim

Apply the latex paint on trim in thin layers. Roll or brush it on and then move onto the next wall. You can use a foam roller for flat surfaces and roll with a paintbrush for stippled walls. When using latex paint, you should wait about 15 minutes between each coat of paint so that it will dry well.

Step 9: Use A Paint Brush

Use a paint stick brush to paint the inside of your door frames, as this allows you more control than a roller. When painting door frames, be sure that you get all areas, including the edges and nooks, thoroughly with 3 coats of paint. To make it easier to reach hard-to-reach places, like the joints and corners of door frames, use a small paintbrush.

Step 10: Clean Up Paint Brush And Rags

Once you are done painting your trim, clean all your brushes with warm water. You may also soak them in soapy water to ensure that they are spotless before storing them away for future use.

Step 11: A Touch Of Glaze

Before you rehang your doors back on the hinges, put a little glaze on the edges where the frames meet. This will make your door look like it has been freshly oiled. It also helps to cover up any orange peel texture that may have formed during painting. 

Step 13: Frame The Window

You can frame your window by putting molding around the edges so that you have a finished look at your room. This also helps make it look like there is no gap between the wall and window frame, which is easily visible if not covered. Finally, recheck the walls for any smudges or drips of flat paint before re-hanging your doors. The last thing you want to do is leave a smear on your freshly painted walls!

How Long it Will Take Paint The Trim?

It is best to allow at least 2–3 hours to complete the painting of your room’s trimming. If you only have a few baseboards or window sills, it should take around an hour and a half for each coat, with drying time between them. For larger rooms with many windows, doors, and baseboards, you will need to allow at least 3–4 hours for the first coat and then an hour or more for each additional coat after that.

Do Trim Colors Make Difference Painting The Trim?

Trim colors can really make a difference in the way your room looks. Therefore, it is important to take painting prep and decide what color you want before you start painting. It’s best to pick a neutral shade instead of bright colors with bold hues so that they blend well with the other features of the room, such as furniture and accents.
