Quality Carpentry House Painting
Choosing the Best Primer
Primer isn’t always necessary—if you’re recoating walls and trim that are in good condition and were previously covered in a similar shade and formulation, for instance. But with new drywall and fresh plaster, primer is essential to seal the surface. And if you’re applying a light color over a dark one, the previous paint job is damaged or deteriorated, or you’re coating a porous or slick surface, using an appropriate primer will ensure optimal coverage.
- Walls: A general-purpose water-based, 100-percent latex formula should do the trick here. If you’re making a big color change, ask your paint store to tint the primer to ensure even coverage.
- Bare wood trim: Manny relies on oil-based primer for this: “It fills and seals the pores so that whatever paint you use will adhere well.”
- Painted wood trim: For trim previously painted with latex, a water-based latex primer is fine. But if you’re unsure what type of paint was used, you may want to use one that’s oil-based.
- Clear-coated wood trim: If the trim has a coat of polyurethane or varnish, shellac primer will provide the best adhesion. Note: Since both oil-based and shellac primers give off volatile organic compounds (VOCs), which can damage your lungs, be sure to work in a well-ventilated space.
Painting or staining exterior house siding and trim is a great way to refresh your home’s appearance and protect it from the elements. Here’s a step-by-step guide:
Materials You’ll Need
- Exterior paint or stain (high-quality, weather-resistant)
- Primer (if painting bare wood or changing colors)
- Paint sprayer, brushes, and rollers
- Painter’s tape
- Drop cloths
- Ladder or scaffolding
- Pressure washer or hose with scrub brush
- Sandpaper or sanding block
- Caulk and putty (for gaps and cracks)
- Safety gear (gloves, mask, goggles)
Step 1: Prep the Surface
- Clean the siding and trim – Use a pressure washer or a hose with soapy water and a scrub brush to remove dirt, mildew, and grime. Let it dry completely.
- Scrape and sand – Remove loose or peeling paint with a scraper. Sand rough areas for a smooth surface.
- Repair any damage – Fill cracks, holes, and gaps with exterior caulk or wood filler. Allow it to dry.
- Protect surrounding areas – Use painter’s tape and drop cloths to cover windows, doors, and landscaping.
Step 2: Apply Primer (If Needed)
- If painting over bare wood, metal, or changing from a dark to light color, apply a high-quality exterior primer.
- Allow it to dry fully before proceeding.
Step 3: Apply Paint or Stain
For Painting:
- Use a paint sprayer for large areas or a roller for smooth coverage.
- Use a brush for trim and edges.
- Apply at least two coats, allowing drying time between them.
For Staining:
- Use a brush or sprayer to apply an even coat.
- Work in sections to avoid lap marks.
- Apply a second coat if needed for richer color and better protection. westchesterpainter.net
