How To Fix Paint Blisters On The Outside?

Blistering is a common issue with paint that occurs when the paint fails to adhere to the surface it was applied to. It can be caused by various factors, such as exposure to direct sunlight, oil-based or alkyd paint over damp or wet surfaces, or moisture escaping through exterior walls. To fix this issue, follow a three-step process: remove damaged paint, prepare the surface for a new coat, and repaint the surface with a high-quality interior/exterior paint.

To remove blisters, use a scraper to remove the largest ones, soap the surface before using a brush and paint. Before filling the surface, make sure to start with a clean surface. For larger blisters, scrape off damaged paint and address moisture issues.

To repair small blisters, sand, clean, priming, and repaint the surface thoroughly. For widespread blistering, scrape off damaged paint and address moisture issues. For excessive heat and sun exposure, scrape off the bubbled paint, sand the surface, apply a primer suitable for the surface, and repaint using a high-quality exterior paint that offers UV protection and is designed to withstand harsh weather conditions.

To fix paint bubbles, remove areas of paint separation (blisters) with sanders, brushes, or scrapers, clean exposed surfaces, sand them, and prime them with high-adhesive paint. If the blisters do not go all the way down to the substrate, remove them by scraping and sanding.

In general, blistering is an indication that the adhesion of the paint film is failing, so simply repairing the blisters is unlikely to cure the problem. For bubbles, scrape them lightly with a large-ish putty knife and then try PPG Break-Through! (Home Depot usually sells it).

In case of improper roller cover use, eliminate the paint bubbles by scraping and patching them.

How to treat paint blistering on wood?

Blistering of paint on plaster can occur when solvent-based paints are overcoated with a conventional emulsion in areas with high levels of condensation. To resolve this issue, scrape back the blistered paint until a firm edge is achieved, feather lightly with abrasive paper, and dust off. Spot, prime, and bring forward any bare areas with Dulux Primer Sealer on friable surfaces, then repaint the surface with a thinned first coat of water-based Dulux Trade Quick Drying Eggshell followed by one or two full coats.

If a paint film over varnish or some wood stains is chipping, it is important to thoroughly clean the surfaces to remove dirt, grease, and surface contaminants. Carefully scrape back poorly adhering or defective paint to a firm edge and rub down to “feather” broken edges. If chipping is severe, the surface will need to be completely stripped back. Dust off before repainting.

Using linseed oil putty for glazing in conjunction with Sikkens woodstains is not recommended due to the loss of drying oils, which allow the glazing compound to dry and crack, causing a failure of the glazing seal. To resolve this issue, use approved elastomeric sealants such as polysulphide, silicone, or acrylic.

Should you pop paint bubbles?

To remove water bubbles in your wall, pop the bubble, peel back the paint, let it dry, and repair the damage.

Can you put primer over paint?

In the event that the wall is in satisfactory condition and the paint is of a similar chemical composition (latex), it is possible to utilise a primer in order to conceal the existing colour and subsequently apply one or two coats of the new paint. A more recent innovation is paint and primer in one, which may prove an optimal solution for your particular circumstances and potentially reduce the overall duration of the project.

Why is my old paint showing through my new paint?

The issue may be with the paint used, which could be defective, old, or low-quality. To address this, try priming an inconspicuous spot, letting it dry, and then painting over it. If that doesn’t work, prime all walls with a stain-blocking primer. If necessary, have the paint store tint the primer to match the finish paint.

How do you fix bubbling paint without repainting?

To remove bubbled paint from surface-level issues, start by scraping off the bubbled paint, sanding it down for primer, filling any holes and cracks with a patching compound, letting it dry overnight, and sanding again with a fine-grit sandpaper. Clean the area, apply a primer, and allow it to dry completely before repainting. Repainting the entire wall or a large section is recommended for a seamless finish, as old and new paint can be noticeable and matching issues may occur if the exact paint used was not used. Repainting the entire wall upfront saves time and headaches in the long run.

What is the best primer for blistering paint?

To prevent blistering, use a quality water-based primer like Auro 505 Grip Coat or Auro 301 Plaster Primer or emulsion paint diluted with 10-20 water. Ensure the priming coat is completely dry before painting to prevent moisture-induced bubbles. To fix paint bubbles, identify the root cause and address damp problems before repainting. If a blister breaks open and there is moisture behind it, a damp proof course can be installed to prevent further damage.

Can you paint over blistered paint?

To address paint bubbles, it is necessary to remove blisters through a process of scraping and sanding. Once this has been completed, the area should be coated with primer before the application of a quality acrylic latex interior paint. In the event that the blisters extend to the substrate, it is necessary to eliminate the moisture source, repair the loose caulking, and consider installing vents or exhaust fans to reduce the humidity within the dwelling.

What is the most common cause for paint blistering?

Blistering is a common issue in vehicle repair and painting due to the saturation of the film by high atmospheric humidity and the presence of water-soluble materials, such as primer. These materials can deform the paint film and weaken adhesion between coats or between the paint process and the metal. Micro-blistering often occurs when vehicles are repaired or painted under adverse conditions. To minimize the risk of blistering, ensure the paint area is clean and dry, use the correct thinner with each coat of paint, and avoid using cheap quality thinners with high moisture content.

Apply sufficient primer and topcoat in even coats, ensuring a sufficient primer film is left after sanding and a similar film weight of topcoat. Low film build can weaken the paint structure and lead to blistering, especially in spot or localized repairs.

During the painting process, ensure the surface is clean, free of grease, and dry. Adhere strictly to flash off and drying times set by paint manufacturers. Rushing jobs may seem like saving time, but in the long run, the vehicle may need further rectification.

How to fix exterior paint bubbling?

The removal of paint separation can be achieved through the use of sanders, brushes, or scrapers. Once this has been completed, the exposed surfaces should be cleaned and sanded before the application of a high-adhesive alkyd primer. Once the primers have undergone the requisite curing period, previously-bubbled surfaces should be repainted in accordance with the established guidelines for blistering prevention.

What causes paint to bubble on exterior wood?

An exterior paint’s breathability refers to its ability to allow moisture to escape from the surface. Low breathability can cause moisture to build up, lifting the paint film and causing it to bubble. Most exterior paints today are acrylic-based, which have low breathability, leading them to fail after 1-3 years. A combination of high breathability and water repellent properties prevents paint from failing. If an exterior paint lacks these properties, moisture will cause it to fail, leading to peeling, bubbling, or cracking.

Poor preparation is another factor that can lead to paint failure. Poor preparation can occur in various forms, but 9 times out of 10 means that the surface was not properly cleaned before applying the paint. Masonry surfaces, in particular, can gather large amounts of dirt and organic growth, which can cause bubbling paint. Therefore, proper preparation is crucial for preventing paint failure.

Why is my old paint bubbling under my new paint?

To prevent paint bubbles, it is essential to prepare the surface properly, make necessary repairs and clean well before painting, and ensure one coat is dry before adding additional coats. Use high-quality paint and a roller with a thick nap to ensure even application. Popular brands include Kelly-Moore, Sherwin-Williams, Benjamin Moore, PPG, Behr, Valspar, and Rust-Oleum.

Use multiple thin coats instead of one thick coat to trap air underneath the paint and prevent bubbling. Allow proper drying time for each coat, as not fully drying can cause air pockets to form and create a bubbled effect. Follow the instructions on the product label.
