How To Prepare Exterior Siding That Is Flaking For Painting?

To paint old peeling wood siding, follow these steps:

  1. Carefully pressure wash the dirt off the siding.
  2. Thoroughly scrape off the peeling paint.
  3. Prime the bare wood with an oil-based primer.
  4. Paint the siding with an all-in-one exterior paint and primer.
  5. Paint the trim and accents.

Preparing your home’s exterior for a paint job can lead to improved paint adhesion, a longer-lasting finish, and an opportunity to identify and repair damage. Power washing the siding is one of the most important steps in this process.

To prepare the siding, start by hosing down the siding and keeping the pressure low. Remove loose paint, such as peeling or blistering paint, and use exterior paint. Cover the work area with plastic or drop clothes to collect paint debris.

For the most basic cedar siding paint job, follow these four steps:

Before painting, ensure that you have cleaned the surfaces being painted, used caulk and putty to fill cracks and nail holes, and priming with a robust priming system. Apply crack filler to cracks or holes using a spackle knife, then lightly sand using a medium-grit sanding block.

Place a coat of “peel bond” on the entire house to smooth it out considerably. For example, prep all the trim on one side, then paint the trim. Prep the siding and paint it.

A water-based binding primer is three times thicker than regular primers and locks down and hides peeling, weathered surfaces to create a smooth, white finish.

Will primer keep paint from peeling?

It is recommended that the walls be primed in order to prevent peeling paint caused by moisture. It is essential to apply a primer to the surface in order to seal it and facilitate the adhesion of the subsequent coat of paint. The surface should then be permitted to dry in accordance with the instructions provided by the manufacturer. The initial coat should be applied in an even layer over the prepared surface. Should additional coverage be required, a second coat should be applied. Once the primer has dried, the tape and drop cloth can be removed, revealing a smooth surface.

What happens if you paint without primer on the exterior?

Before painting, it is essential to coat new, bare surfaces with primer to ensure even paint coverage and proper adhesion. This is because most bare surfaces have pores and imperfections that can cause uneven paint coverage. After removing old paint, it is crucial to apply a primer to prevent the paint from falling away. Additionally, primer can be used for aesthetic reasons, such as covering up previous colors and emphasizing new ones.

Tinted primer, which is the same color as the paint, can help cover up the previous tone and emphasize the new one, as the old paint won’t bleed through the primer and the new paint won’t soak through. In summary, priming new surfaces, removing old paint, and using tinted primer are essential steps in preparing for a successful paint job.

What happens if you don’t sand before repainting?

Sanding is a crucial step in preparing surfaces for painting, as it helps remove imperfections and roughen glossy surfaces for paint or filling compound to adhere easily. It can be done by hand or with electric tools, and it is essential for removing imperfections on walls, ceilings, furniture, and floors. Oversanding and undersanding can occur, but it is essential for a smooth and durable finish. Despite the potential risks, sanding is a simple process that requires patience, protective gear, and elbow grease.

Do you need to prime exterior siding before painting?

To create a cohesive paint job, it is essential to prime the entire house, especially if using latex paint over an oil-based surface. Surface prep is vital for health and safety reasons, as well as ensuring the new paint job looks good and lasts. To remove contaminants, it is essential to consult a certified contractor who can handle lead abatement before starting the process. Test the paint before proceeding with any further exterior painting prep.

Mold or mildew is a common contaminant, especially in humid areas. Look for black, green, or brown stains with a fuzzy appearance. If unsure if a stain is mold or mildew, apply common bleach. If it bleaches away, you have killed some mold or mildew. Use bleach or another EPA-registered microbiocide or fungicide to remove mold and mildew. Look for cleaners and degreasers that can remove grime, grease, and oil.

Do you have to sand siding before painting?

The preparation phase of exterior painting is crucial, involving scraping or sanding to remove loose or raised areas before sanding. Sanding can be done by hand or power, depending on the surface area and the minimal peeling paint or stain. Hand sanding is common for small surfaces with multiple angles or levels, such as gutters, fluted columns, dental moldings, crown moldings, and louvered vents.

Sandpaper selection is also important, with grits ranging from 36 to 50 grit. When using hand sand paper, it should be folded in half from top to bottom and separated in the middle, allowing for use on top, bottom, and interior portions.

EPA guidelines require hand scraping for painted surfaces older than 1978 due to lead paint laws. A feathered edge is achieved by sanding the painted edge to a tapered transition to the bare wood, leaving a smooth, jagged edge between the old paint and bare wood. Scraping only on older homes with lead will result in an un-feathered edge, leaving a defined jagged edge between the old paint and bare wood.

How to prepare peeling paint for repainting?

To guarantee a durable paint finish, it is essential to begin by removing any loose and flaking old paint from exterior surfaces using a paint scraper and wire brush. The flaking paint should then be removed by sanding with 80 to 100-grit sandpaper. It is of the utmost importance to ensure that painted walls are properly cleaned, as any debris or contaminants between the paint and the wall can accelerate the deterioration of the paint, leading to peeling or cracking.

Can I paint over peeling exterior paint?

The ability to paint over peeling paint depends on the underlying cause. If it’s due to poor adhesion or surface preparation issues, it’s possible to paint over it. However, if it’s caused by moisture, mold, or structural issues, addressing the root cause is crucial. To fix and paint over peeling paint, assess its extent, identify loose, flaking, or blistering areas, and gently remove the paint with a scraper or putty knife, avoiding damage to the underlying surface.

Should I remove peeling paint before repainting?

To ensure proper adhesion, remove peeling paint before applying a fresh coat. Use a scraper or 100-grit sandpaper to remove loose or cracked paint from damaged areas. Prep uncoated and previously coated concrete surfaces with the 9 in. x 1/4 in. Polyester Adhesive Roller Cover, available in-store at Home Depot. This hard texture is ideal for applying adhesives to smooth surfaces and can be used for stippling and applying sand paints.

How do I know if my siding is dry enough to paint?

How do I know if my siding is dry enough to paint?

Wood siding on old houses can be a significant issue due to the presence of paint-killing moisture inside buildings in cold climates. Old wood-frame homes are particularly susceptible to this issue, as they were built before vapor barriers on warm sides of exterior walls. As warm, moist indoor air cools to the dew point, moisture condenses out of the air, forming water droplets and frost within walls. As the weather warms, the frost melts and the moisture migrates outwards through wood siding.

Premature paint peeling in localized areas that don’t get extra moisture from outside sources is a sign of an internal moisture problem. A moisture meter is the fastest way to verify moisture issues on wood siding. Post-flood restoration work presents an unfair hazard for painters, as wall frames, floor frames, and concrete slabs will be very wet after a flood. The moisture of a too-wet wall frame or floor will eventually come through drywall to your painting, and paint failure will be seen as your fault. If possible, take moisture readings of the wall framing before fresh drywall goes up, or wait as long as possible before moisture testing drywall.

Moisture content vs. relative humidity is important when measuring the moisture content of wood. An electric meter determines the moisture content percentage by measuring the electrical resistance of the wood. A 1, 000-gram block of wood with a moisture content of 14% contains 140 grams of water. Conversely, “relative humidity” is often used to measure the moisture content of concrete slabs, which is different from “moisture content”. A slab with a relative humidity of 70% holds 70% of the maximum amount of moisture that the air in the hole can hold at that particular temperature.

Can peeling paint be painted over?

To ensure proper adhesion, remove peeling paint before applying a fresh coat. Use a scraper or 100-grit sandpaper to remove loose or cracked paint from damaged areas. Prep uncoated and previously coated concrete surfaces with the 9 in. x 1/4 in. Polyester Adhesive Roller Cover, available in-store at Home Depot. This hard texture is ideal for applying adhesives to smooth surfaces and can be used for stippling and applying sand paints.
