Exterior Painting: Trim First?

should you paint the trim first with exterior painting

When it comes to exterior painting, there are differing opinions on whether to paint the trim or siding first. Some professional painters argue that painting the trim first is more efficient, as it's easier to tape off the trim than the walls, resulting in a cleaner line. Additionally, painting the trim first can help avoid paint splatter on the freshly painted siding. However, others suggest that painting the siding first minimizes the need for masking and reduces the likelihood of touching up the trim. Ultimately, the decision may depend on factors such as the surface texture, the use of a spray machine or brush, and the colour of the trim.

Taping the trim

Wipe Down the Trim

Use a damp cloth to wipe down the trim before taping. This step is crucial, as it ensures that the tape will adhere properly to the surface. A clean surface will help the tape stick better and create a stronger barrier against paint.

Choose the Right Tape

Select a high-quality painter's tape designed for delicate surfaces. The tape should be strong enough to withstand paint without peeling off but also easy to remove without leaving residue or damaging the trim. One recommended brand is "Kleen Edge," which professional painters prefer for its effectiveness in preventing paint bleed.

Apply the Tape

When applying the tape, it is essential to leave a small gap between the trim and the wall. Place the tape about a dime's width from the joint between the trim and the wall. This gap will be filled with paint to create a seamless joint.

Seal the Edges

After taping, use a sharp utility knife to cut along the seam between the trim and the adjoining surface. This step will help ensure that paint doesn't bleed underneath the tape.

Use a Light Touch

When painting, it is essential to use a light touch and a properly loaded brush or roller. Gently roll or brush over the tape, ensuring that the paint flows effortlessly off the brush. Avoid pressing too hard, as this can force paint under the tape and compromise your clean lines.

Remove Tape Promptly

Once you've finished painting, remove the tape as soon as possible. Delicate tape is designed to be removed quickly, so don't let it stay on for extended periods. Removing the tape while the paint is still wet will help you achieve clean lines and prevent any peeling or residue.

Painting the siding first

Painting the exterior of your home can be a stressful and daunting task. If you are painting vinyl siding, it is important to check whether painting the siding will void its warranty. If the warranty permits painting, be sure to comply with any stipulations from the manufacturer, such as the type and colour of paint to use. It is also important to consider the colour of paint you will be using. If you are using a paint that is vastly different from the existing colour, you will need to prime the vinyl first. You should also use paint that is the same shade or lighter than your current siding colour. This is because darker colours will attract more heat, which is not ideal during the summer.

Before painting, it is important to prepare the surface. The siding should be cleaned with a cleaning solution and then hand-scrubbed with a soft-bristled brush, sponge, or rag to remove all dirt, grease, and chalkiness. Work from the bottom up, and thoroughly rinse each section immediately after scrubbing. If you are using a pressure washer, check the manufacturer's instructions first and direct the stream of water downward to prevent getting water behind the siding.

When painting, use an even coat of exterior paint, and let the first coat dry as directed by the manufacturer. Then, apply a second coat and let it dry. If you are painting wood siding, carefully pressure wash the dirt off the siding, and then scrape off the peeling paint. Next, prime the bare wood with an oil-based primer, and finally, paint the siding with an all-in-one exterior paint and primer.

If you are using tape, it is generally recommended to tape off the trim first and then paint the siding. This is because it is easier to put the tape on the trim than on the wall. However, some people prefer to paint the siding first, especially when spraying, as it minimises the masking needed.

Using a spray machine

  • Choose a spray machine that is easy to use and suitable for exterior painting, such as the Graco or Wagner sprayers.
  • Gather your materials, including the sprayer, exterior paint and primer (enough for two coats), paper or plastic sheeting, painter's tape, canvas drop cloths, a dust mask, and safety glasses.
  • Prepare the area by moving all furniture and items away from the area to be sprayed. Tape off any trim and cover any surfaces you don't want to be sprayed, such as windows or shrubs, with paper or plastic.
  • If you are using a pressure washer, clean the entire exterior surface and allow it significant time to dry. Otherwise, thoroughly wipe clean all the trim and door surfaces and let them dry.
  • Lightly sand the surface with fine sandpaper to increase paint adhesion, then wipe again to remove dust.
  • Select the spray tip that is best suited for the paint you are using and the surface to be sprayed. Ensure the tip's hole size does not exceed the maximum capacity of your sprayer.
  • Practice spraying on a piece of cardboard to get a feel for the spray pattern and adjust your airflow, material flow and spray width until you are satisfied.
  • When spraying, keep the sprayer 6-8 inches away from the surface to ensure even coverage and minimum overspray. For doors, overlap each successive spray pass by approximately 50%.
  • Wipe off the tip with a damp rag every few minutes to prevent clogging.
  • Allow significant time for the paint to dry before removing tape from the trim for crisp, clean lines.
  • Clean your sprayer after each use following the directions in the user's manual.

Remember to always take proper safety precautions when operating a spray machine. Wear protective gear such as gloves, safety glasses, a spray sock, hat, proper footwear, and a dust mask or respirator. Ensure there is adequate ventilation and refer to the specific instructions and safety procedures for your spray equipment.

Painting walls first

One key reason to paint the walls first is when using high-gloss trim paint. High-gloss paint is challenging to work with, and painting the walls first can help avoid getting glossy paint on the walls, which is tougher to cover up. Painting the walls first in this case can save time and effort in achieving a neat finish.

Another consideration is the impact of wall colour on the overall aesthetic. If there is a possibility that the wall colour might be changed, it is advisable to paint the walls first. This way, if the wall colour changes, the trim colour can be adjusted accordingly, avoiding the need to repaint both surfaces.

Additionally, for large projects or those with time constraints, painting the walls first can provide a psychological boost. Seeing the inkling of the final product can motivate individuals to complete the project. Painting the walls first can also be advantageous when there is still work traffic in the room, as it reduces the chances of the new wall paint getting marked up.

Furthermore, painting walls can be faster and require less skill and precision than trim work. Painting the walls first can help make noticeable progress, especially with a larger crew. This approach can be beneficial when using a sprayer, as it covers a more extensive area, and doing the trim first may result in continual touch-ups.

Caulking the trim

Caulking is an important step in many painting projects, as it fills in gaps and cracks, ensuring the paint adheres properly to the surface. It also enhances the aesthetic appeal of your home by creating a clean and polished look.

When caulking the trim, it is essential to choose the right type of caulk. For caulking trim, a paintable latex caulk is a good option as it can be painted over once dry. If you are caulking exterior trim, you will need a caulk that can withstand exposure to the elements, such as rain and UV rays. Silicone-based or polyurethane-based caulks are typically best for outdoor use due to their ability to endure extreme temperatures and weather conditions while remaining waterproof.

Before caulking, it is recommended to use a primer on the surface to help the paint stick better. Once the primer is dry, you can apply the caulk. Use your finger or a caulk smoothing tool to smooth it into the gaps and remove any excess with a damp cloth or sponge. Allow the caulk to dry completely according to the manufacturer's instructions before painting over it.

Additionally, taping can be used in conjunction with caulking to achieve perfectly straight lines. Run tape along the trim, leaving a small gap between the tape and the joint, then fill the gap with caulk. After the caulk has dried, paint over it, allowing the paint to lap onto the tape. Once the paint is dry, remove the tape, and you will be left with a perfectly straight line.
