Painting Trim: A Comprehensive Guide for Interior and Exterior Trim
What is trim? This is the frame around the door, the windowsill, any borders on the wall, rails on some stairs, or any part of the home that has edging. Keeping the trim neatly painted is an essential part of maintaining the appearance of your home. Inside or outside, well-painted trim can provide a crisp, finished look that boosts your home’s appearance.
Why Paint Trim?
Trim serves both functional and decorative purposes. It frames doors, windows, and other elements, creating a finished look and protecting edges from wear and tear. Over time, however, trim can become chipped, faded, or outdated. It comes into contact with human hands much more than more wall surfaces. Some fresh paint can rejuvenate your trim, protect the underlying material, and add to the overall beauty of your home.
Tools and Materials Needed
Before starting, gather the necessary tools and materials:
- Sandpaper or sanding blocks (120- to 220-grit)
- Painter’s tape or masking tape
- Drop cloths or plastic sheeting
- Putty knife and wood filler (for interior trim) or exterior wood filler (for exterior trim)
- Caulk and caulking gun
- Primer (stain-blocking primer for interior, exterior primer for outdoor trim)
- High-quality trim paint (choose an exterior-grade for outside and a durable enamel for inside)
- Paintbrushes (angled sash brushes work well for trim)
- Cleaning supplies (soap, water, tack cloth)
Preparation
As always, proper preparation is half the job. It is crucial for a long-lasting, professional finish.
Cleaning
Start by cleaning the trim to remove dust, dirt, and grease. For interior trim, use a mixture of water and mild detergent. For exterior trim, a power washer can be used for thorough cleaning, but ensure the wood is completely dry before painting.
Sanding
Next, sand the trim to smooth out any rough spots and help the paint adhere better. Use fine-grit sandpaper for this task. After sanding, wipe the trim with a tack cloth to remove any dust.
Repairs
Inspect the trim for any damage. Use a putty knife and wood filler to repair interior trim, and exterior wood filler for outdoor trim. Fill in any holes, cracks, or dents, then sand smooth once dry. If you encounter gaps between the trim and walls or other surfaces, use caulk to fill them. Smooth the caulk with a wet finger or a caulking tool and let it dry completely.
Taping
Apply painter’s tape around the edges of the trim to protect adjacent surfaces. Use drop-cloths or plastic sheeting to cover floors and furniture.
Priming
Priming is essential, especially if the trim is bare wood, stained, or has never been painted. Apply a stain-blocking primer for interior trim and an exterior-grade primer for outdoor trim. Priming helps seal the wood, providing a uniform surface for the topcoat and improving paint adhesion. Allow the primer to dry according to the manufacturer’s instructions and sand lightly for a smooth finish.
Painting Interior Trim
When painting interior trim, use high-quality, durable enamel paint. High-gloss finish paints are preferred here as they are easy to clean and quite durable. They also contrast nicely with the matt or eggshell finish paint used on most walls.
1 – Start with the Edges
Use an angled sash brush to paint the edges of the trim first. This helps create clean lines and prevents paint from pooling on the flat surfaces.
2 – Paint the Flat Surfaces
After the edges, paint the flat surfaces of the trim. Apply the paint in long, smooth strokes, following the grain of the wood. Be sure to catch any drips or runs immediately.
3 – Multiple Coats
Two coats of paint are usually recommended for the best coverage and durability. Allow the first coat to dry completely before lightly sanding and applying the second coat.
4 – Remove Tape
Carefully remove the painter’s tape before the final coat is fully dry to avoid peeling paint.
Painting Exterior Trim
Exterior trim is exposed to the elements, so it requires a different approach and materials.
1 – Choose the Right Paint
Use a high-quality exterior paint that can withstand weather conditions. Satin or semi-gloss finishes are typically used for exterior trim.
2 – Weather Conditions
Paint in moderate weather, avoiding extreme temperatures and high humidity. This ensures the paint cures properly and adheres well.
Application: Start with the edges and detailed areas, then move to the flat surfaces. Apply the paint in even, smooth strokes to avoid brush marks.
3 – Multiple Coats
Like interior trim, exterior trim usually requires two coats for optimal coverage and protection. Allow adequate drying time between coats.
Final Touches: After the final coat, inspect for any missed spots or uneven areas and touch up as necessary.
Maintenance
Regular maintenance helps keep the trim, and thereby the rest of the house, looking its best. Clean interior trim with a damp cloth to remove dust and grime. For exterior trim, inspect it periodically for signs of wear or damage and touch up as needed. This is important as water can get inside the home through damaged trim around doors or windows. Properly maintained trim will not only look great but also protect your home for years to come.
