How To Prepare Outside Molding For Painting?

This DIY tutorial and video provides a step-by-step guide on how to prep for painting exterior trim without sanding. First, apply primer to the trim, covering any bare wood and spackled areas, and let it dry for 24 hours. If bare wood or spackle is present, apply another coat of primer. After the primer dries, lightly sand the trim using 120-grit sandpaper to eliminate brush strokes or paint drips.

To prepare the surface, sand down any rough edges and clean off dirt or grime. After washing the exterior trim, allow it to dry before painting to make it easier to scrape off remaining paint and prevent damage. The surface should be clean, dull, and dry.

To prepare the trim, pressure wash it, inspect it, scrape it showing failure, caulk all exposed trim outside, fill all holes, scrape or brush/rough sand any flaking areas, seal around borders, wash with TSP, prime, and paint with a sprayer.

After scraping off peeling paint, fill the holes with exterior wood filler like Elmer’s ProBond Max Wood Filler. Exterior wood trim should be washed with a mild solution of bleach and water to remove surface debris and mildew. Once the paint is scraped, sand, and prime the trim using a Purdy Nylox paint brush.

How do you prepare painted trim for repainting?

To clean a new or smooth trim, lightly sand it with 120-grit sandpaper until all shine disappears. If the trim is rough and worn, start with 80-grit sandpaper and then move to less-coarse sandpaper. Dust off walls and ceilings around the trim to ensure painter’s tape adheres well. Apply painter’s tape to walls and ceilings surrounding the trim, being careful not to stick to the trim itself. Use one long piece of tape instead of multiple shorter pieces.

Do you need to sand exterior paint before repainting?

Sanding old paint on exterior walls, trims, and siding is crucial for the durability of the job. To remove loose paint, use a scraper to scrape all surfaces, applying enough pressure to avoid gouges. Use a wide scraper for siding and a smaller one for trim, windows, and doors. Coarse sandpaper is recommended for smooth sanding, gradually removing paint differences between paint and adjacent wood. Orbital sandpaper can be used for larger areas, but a sanding block is recommended for trim and tight spaces. Sand off any paint that didn’t need scraping to coarsen the surface for better adhesion. It is essential to avoid applying too much pressure to avoid gouges.

What is the best cleaner for trim before painting?

In order to clean a trim, it is first necessary to wash the surface with a low-phosphate cleaner and then rinse it thoroughly. Loose paint should then be removed with a putty knife. It is recommended that a high-quality latex wood patch be applied to the damaged areas, with a slight excess of the material overfilled to accommodate shrinkage. The filler should then be permitted to dry. The repaired area should then be sanded with 150-grit sandpaper until a smooth finish is achieved. In the event of the filler shrinking, it is necessary to reapply another layer and sand it after it has dried.

How do you wash exterior trim before painting?

It is recommended that the trim be rinsed with a garden hose and allowed to dry for a minimum of two days prior to painting. In the event that aggressive washing causes the emergence of spots, it is recommended that these be removed by scraping. In the event that the trim has a solid coating, it is sufficient to prime only the bare spots. In the event of rusty nail heads, it is recommended that a rust-inhibiting primer be applied, that the heads be countersunk, and that filler be used over them. In the event that the surface is coated with a uniform layer of paint, it is only necessary to apply primer to the bare spots.

Do I need to prime trim before repainting?

A separate coat of primer is necessary for trims with a paint coat if they are being drastically changed in color. White primer is suitable for light colors and can be tinted to match darker shades. If latex paint is being applied over oil-based paint, a cotton ball soaked with rubbing alcohol should be tested to determine if it comes off. If the paint is in bad shape, scrape away loose paint and fill holes with wood filler and sand before priming.

The process for priming and painting is the same, starting with a clean and dry trim free of loose paint, holes, dirt, or dust. If a crisp, clean line is not possible with a brush, painters tape can be used along the edges.

Can you paint over painted trim without sanding?

Paint over wood trim without sanding it, as long as it’s clean and deglossed. If you’re satisfied with the current trim design, use the correct technique and paint it in any desired color. When selecting paint, consider type, sheen, color, and brand. Shinier paints are more durable and hold up better over time. Semigloss offers a classic look and is easily wipeable. Satin paint offers a contemporary look with a matte finish and is durable. Satin trim painting is a great option for those who prefer a more contemporary look.

Should I prime over old exterior paint?

Primer is a crucial component in painting masonry, as it acts as a sealant to prevent moisture from seeping into cracks and causing damage. It is especially important for bare wood, as it is difficult for paint to adhere to and provides additional protection against moisture. Primer also gives wood more vibrant colors when painted over, as natural oils in wood tend to dull when painted directly on top. In addition, primer is recommended for masonry, as it is essential for preventing water damage and ensuring the longevity of the paint job. Therefore, primer is a vital component in masonry painting.

Can I just paint over old exterior paint?

Painting over old exterior paint can give your home a fresh, updated look. If the existing paint is of the same type and the exterior is in good shape, you can paint without sanding. However, if the exterior is wood, you may need to sand it for proper paint application. Before painting, it’s essential to assess the state and type of the existing paint. A prime may not be necessary if the old paint is in good condition and adequately adhered to the surface.

Does exterior trim need primer?

To paint your home’s exterior professionally, start by priming the trim with a primer to seal and protect the wood. Use an angled paint brush to apply the primer, stirring it with a paint stick and pouring it into a paint tray or attaching the paint can to a ladder. Dip the brush about ½ to 1 inch deep into the liquid, wiping off excess to prevent drips. Apply a coat to the wood.

Allow the primer to dry for several hours before covering it with paint color. Latex primers typically dry in an hour, while oil-based primers take 24 hours. Follow the instructions on the container to ensure you’re giving primers enough time to dry. This will help ensure the new paint color looks its best and ensure a smooth and professional finish.

How to prep old exterior trim for painting?

To apply paint, ensure the surface is clean, dull, and dry. Remove loose paint, sand, and prime any bare spots. Use an oil-based primer like Hirshfield’s product number 88-6050 for superior penetration and adhesion. Coat with high-quality acrylic latex paint like Housecoat or Platinum Exterior, with a sheen for a smoother, more durable finish. Use Peel Bond, a combination primer, bonder, and wood stabilizer, for peeling problems on horizontal bottom surfaces. Apply two coats of paint over either primer or Peel Bond for a thicker, longer-lasting paint film.

What happens if you don’t sand before repainting?

Sanding is an essential stage in the preparation of surfaces for painting, as it guarantees the correct adhesion of paint to the surface in question. It is possible for the sanding process to be carried out incorrectly, and it is not necessary to possess professional skills in order to sand a surface.
