Painting baseboards and trim is a great way to update your home. When it comes to priming and painting unprimed trim, there are a few important steps to follow. Firstly, ensure that the trim is clean and dry, with no loose paint, holes, dirt, or dust. If necessary, fill any holes with wood filler and sand the trim to create a smooth base for the primer. Then, apply a coat of primer to the trim, followed by one or two coats of paint, allowing each coat to dry thoroughly before applying the next. It is worth noting that most mouldings sold in retail stores come with a factory-applied primer, so it is only necessary to prime solid pine or unprimed finger-joint moulding.

Ensure the trim is clean and dry before priming
Before priming unprimed trim, it is essential to ensure that the surface is clean and dry. This step is crucial because it guarantees a smooth and uniform application of the primer, promoting better adhesion and a high-quality finish. Here are some detailed instructions to ensure your trim is adequately prepared for priming:
Start by thoroughly cleaning the trim surface. Use a mild detergent or a 50/50 mixture of vinegar and water. This step will remove any dirt, dust, grease, or grime that has accumulated on the trim. It is essential to ensure that the cleaning solution is suitable for the type of trim you are working with (wood, metal, or plastic). Always test the cleaner on a small, inconspicuous area first to check for any adverse reactions.
Once the cleaning is complete, rinse the trim surface with fresh water, ensuring no soap residue is left behind. Then, dry the trim thoroughly. Use clean, absorbent cloths or towels to wipe down the surface. Make sure to get into any grooves or crevices, ensuring no water is left behind, as this could cause issues with adhesion or promote the growth of mould or mildew. If the trim is in a well-ventilated area, allow it to air-dry for a few hours after wiping to ensure no moisture remains.
If you are working with a wooden trim, lightly sand the surface after cleaning and drying. Use fine-grit sandpaper (around 220-grit) and sand in the direction of the wood grain. This step will smooth out any raised grain and create a slightly rough surface, improving primer adhesion. Be sure to remove any sanding dust with a tack cloth or a damp cloth after you're finished.
For metal or plastic trim, you may need to use a deglosser or liquid sandpaper after cleaning and drying. This step will help scuff up the surface, creating better adhesion for the primer. Follow the manufacturer's instructions for application and safety when using these products.
Finally, ensure that the trim is free of any residue or contaminants before priming. Use a clean cloth lightly dampened with mineral spirits or denatured alcohol to give the trim a final wipe-down. This step will remove any remaining oils or residue that could interfere with the primer's adhesion. Allow the trim to dry completely after this step before proceeding with priming.
By following these steps, you will ensure that your unprimed trim is properly cleaned and prepared, providing an ideal surface for primer application and ensuring a durable and aesthetically pleasing finish.

Use a caulking gun to fill gaps with sealant
Caulking guns are used to fill gaps and cracks with caulk or sealant. They are especially useful for sealing gaps around windows and door frames, which can keep out insects, seal out moisture, and reduce the flow of heat. Caulking guns can also be used to fill gaps in high-moisture areas like the kitchen and bathroom, where caulk can be used to seal moisture and prevent it from seeping into walls, behind cabinets, or even behind tub or shower tiles.
To use a caulking gun, follow these steps:
- Prepare the area by cleaning and masking the surface. Scrape away any old residual caulk with a putty knife, utility knife, or caulk removal tool. Then, rinse the area with a rag, hot water, disinfectant, and rubbing alcohol to remove any dirt.
- Inspect the area and determine the thickness of the caulk bead needed to fill the gap. The tip of the caulk tube will determine the thickness of the bead. For a narrow bead, cut the nozzle at a 45-degree angle near the top of the tip. For a thicker bead, cut the nozzle at a 45-degree angle slightly lower down.
- Load the caulk tube into the caulking gun. Press the release trigger to pull the rod back, creating space for the caulk tube. Insert the tube with the nozzle facing outward and the flat side facing you, resting near the trigger end. Ensure the tube is secure and snug.
- Pierce the nozzle. Most caulk guns have a piercing rod, but if yours does not, use a sharp nail to puncture the tube.
- Before applying the caulk, do a practice run on a piece of paper to get a feel for the application.
- Hold the caulking gun at a 45-degree angle and apply pressure to the trigger to release the caulk. Move the gun slowly and steadily across the length of the crack in a single, smooth motion.
- If needed, go back and fill in any missed spots with a second pass.
- Smooth the caulk line with a gloved finger, a caulking finishing tool, or a caulking edger. Wet the tip of your finger with warm water and drag it along the line of caulk to create a clean finish.
- Clean up any excess uncured sealant with a damp sponge before it skins over. Cured sealant must be cut or scraped away.
- Allow the caulk to dry. Refer to the instructions on the caulk tube for the precise drying time.
By using a caulking gun to fill gaps with sealant, you can ensure a smooth and professional finish to your project.

Sand and prime the trim
Sanding and priming your trim before painting is an important step to ensure a smooth and flawless finish. Here's a step-by-step guide to help you through the process:
Sand the Trim
Start by lightly sanding the trim with a sanding sponge or sandpaper. Use a medium/fine-grit sanding sponge or 220-grit sandpaper, which will help you achieve a smooth finish. Sand the trim gently, ensuring you don't apply too much pressure, as you just want to create a smooth surface for the primer and paint to adhere to. A sanding sponge is ideal for getting into crevices and applying even pressure. If your trim has already been installed, be careful not to damage the surrounding surfaces.
Vacuum and Wipe the Trim
After sanding, use a vacuum to remove the debris and dust created by the sanding process. This step is crucial as it ensures that the dust and debris don't get stuck to your primer or paint, creating an uneven finish. Once vacuumed, take a clean, slightly damp rag and wipe down the trim to ensure it is free of any remaining dust and to remove any remaining debris.
Prime the Trim
Now it's time to prime the trim. Choose a primer that is suitable for the surface you are working with. If you are priming solid pine or unprimed finger-joint moulding, opt for a high-quality primer. Refer to the instructions on your chosen primer for specific directions. Typically, you will need to apply 1-2 coats of primer. Allow the first coat to dry completely before adding the second coat. The primer will ensure an even finish and enhance the colour of your chosen paint.
Sand Again (Optional)
If you want to achieve an extremely smooth finish, you can lightly sand the primed trim with a fine-grit sanding sponge. This step is optional but will help create an exceptionally smooth surface for your paint. Just be sure to vacuum and wipe the trim again after this sanding step to remove any dust.
Apply Paint
Finally, it's time to apply your chosen paint. Refer to the instructions on your paint can for specific directions and the number of coats required. Typically, two coats of paint are recommended, allowing the first coat to dry completely before applying the second.
Remember to always work in a well-ventilated area and wear the appropriate protective gear when sanding and painting.

Apply two coats of paint
Painting baseboards and trim is a great way to update your home. Whether you are going from one colour to another, or just applying a fresh new coat of paint, there are some tips and tricks to help you get great results!
Firstly, ensure your trim is clean and dry, with no loose paint, holes, dirt or dust. If there is any flaking paint, fill holes with wood filler and sand before priming to ensure a good base surface for your paint to adhere to.
Now, you are ready to apply your top coats of paint. Typically, you should apply two coats of paint and wait for the first coat to dry completely before applying the second coat. Remember to remove the painter's tape immediately after finishing to prevent the tape from damaging the wall or surrounding trim.
If you are painting solid pine moulding or unprimed finger-joint moulding, you should use a high-quality primer. In most cases, you will only need one coat of primer. However, you may need two coats of primer if you are using a lower-quality primer.
Finally, as many home remodelling blogs say, choose a gloss or semi-gloss paint sheen to ensure durability, and you'll have updated, beautiful trim that will last for years to come!

Choose a gloss or semi-gloss finish for durability
When it comes to choosing a paint finish for your project, there are several factors to consider, including the desired level of shine or gloss, durability, ease of cleaning, and the type of room being painted. Here are some reasons why you should choose a gloss or semi-gloss finish for durability:
Gloss and Semi-Gloss Paints Offer Superior Durability:
Gloss and semi-gloss paints have a higher sheen or shine compared to flat, matte, or eggshell finishes. This higher gloss level translates to increased durability. The glossy finish forms a tougher surface that can withstand scrubbing, stains, and moisture better than lower-gloss alternatives. As a result, these finishes are less likely to chip, fade, or become damaged over time.
Stain Resistance and Ease of Cleaning:
Gloss and semi-gloss paints are known for their excellent stain resistance. Their smooth and non-porous surface makes it difficult for stains to penetrate and adhere, making them ideal for areas prone to stains, such as kitchens and bathrooms. Additionally, the glossy finish makes cleaning a breeze. Any dirt, grime, or fingerprints can be easily wiped away, keeping your surfaces looking pristine.
Moisture Resistance:
Semi-gloss paints, in particular, offer high resistance to moisture. This makes them an excellent choice for areas with higher humidity, such as bathrooms, kitchens, and laundry rooms. They can withstand moisture exposure without peeling, blistering, or promoting the growth of mildew or mould.
Versatility in Application:
While gloss and semi-gloss paints are commonly used for trim, cabinets, and doors, they are also versatile enough to be used in various rooms throughout the home. For example, a semi-gloss finish can be applied to walls in high-traffic areas like hallways or playrooms, as it is more durable and easier to keep clean.
Longevity and Cost-Effectiveness:
The increased durability of gloss and semi-gloss finishes means that your paint job will last longer and require less frequent touch-ups or repainting. This can save you time and money in the long run, making it a cost-effective choice for those seeking a long-lasting paint finish.
In summary, choosing a gloss or semi-gloss finish will provide you with a durable, stain-resistant, and easy-to-clean surface that is well-suited to a variety of applications. While these finishes may require more prep work and sanding, the final result will be a sleek and durable finish that enhances the appearance and functionality of your space.
