How To Fix Bubbling Paint From Water Damage

Bubbles may appear when paint separates from the surface due to water damage. These bubbles have the potential to cause paint to chip and peel from the surface over time. Paint can become stained as a result of the different minerals in water discoloring it.

The structural integrity of the structure may also be damaged by prolonged moisture exposure, which could cause the materials to decay or rot.

Why There’s Bubble In My Paint?

Below are the causes why bubbles form in a structure.

Excessive Heat

Paint bubbles may appear as a result of overheating. Hot weather can occasionally cause fresh paint thinners to evaporate and expand, resulting in bubbling and peeling.

Trapped Moisture

The most frequent cause of paint bubbles is trapped moisture. Sometimes moisture seeps into the paint, particularly in high-humidity areas and when structural materials (such as drywall) are moist just before painting it. A bubble is formed when moisture is trapped beneath the paint.

Low-Quality Paint

Sometimes bubbles on a painted surface are caused more by the paint applied on top of the surface. Fillers are frequently included in low-quality paint, which hinders the paint’s ability to stick to surfaces. This may occasionally result in bubbles forming.

Applying the paint correctly can prevent air bubbles from forming when it dries, so be careful when using a roller or brush.

Roof Leaks Or Plumbing Leaks

On painted surfaces, plumbing or roof leaks—which are frequent during rain—can occasionally result in bubbles. As a result of the moisture from these leaks, your ceiling or walls may begin to sag or bubble widely on the drywall underneath the paint.

Not Compatible Paint

Not all surfaces can accommodate paint, and applying the incorrect paint to the incorrect surfaces may result in bubbling. Such instances include painting oil-painted door jambs without adequate cleaning or preparation, painting walls coated in a thin coating of grease or dirt accumulation, and attempting to apply water-based latex paint above oil paint without first priming the surface.

Improper Paint Thinning

Paint may bubble if an excessive amount of thinner or diluting chemical is added. This happens because the thinner weakens the binding agents in the paint, which leads to the formation of air bubbles.


Guide: How To Fix Bubbling Paint From Water Damage

For any situation when contaminated water creates a water bubble, you will need professional assistance to patch your wall and repair the bubble.

You can, however, empty the bubble and fix the damage if you don’t think the water is contaminated. Here’s how to fix bubbling paint from water damage:

Step 1: Find The Source

Look around to find out where the water damage is coming from. Find the leak by following the path taken by the water. While the roof is often the source of leaks, leaks can also originate from adjacent gutters, windows, and doors. Other significant causes of leaks are home appliances and plumbing.

Step #2: Dry The Area

Start the process of drying the area after finding the source. To speed up the drying process, utilize dehumidifiers, fans, open windows, and towels.

Step #3: Burst The Bubble

On the surface below the water bubble, lay a layer of fresh towels. Using a sharp knife, cut a split into the bubble at its lowest point. By doing this, the bubble is prevented from developing into a “cup,” which would collect water as it drains.

Squeeze the bubble with your hand from top to bottom to get rid of all the water and air pockets behind it.

Step #4: Peel The Paint

Assess the damage and peel any paint from the damaged area with a paint scraper. Look for any indications of mold growth on the surface, such as discoloration or a musty odor.

Make sure you touch the drywall that’s hiding the water bubble. You will have to take that piece of drywall off if it is mushy and soft.

Step #5: Dry The Area Again

To get rid of any residual moisture, pat the damaged area with dry towels. Then, utilize some fans to help dry out every last bit of moisture.

Keep in mind that it can take up to two days for the area to dry, particularly if there is a large bubble or a lot of water in it.

Step #6: Repair The Damage

Before you start repainting, replace any damaged drywall if necessary. Apply a thin layer of filler to the damaged area, even if you did not remove the drywall, so you have a dry surface on which the paint will stick.

Prime the area as usual when the filler has dried.

Step #7: Repaint The Surface

Use the appropriate brush or roller to repaint the surface once the primer coat has fully dried. To prevent bubbles from forming, stir the paint carefully and brush or roll at a moderate pace.

Remember that applying oil-based paint directly over water-based latex paint may cause the two coats to separate and perhaps produce bubbles.


Things Not to Do

Any of the following actions will result in further damage:

  • Popping a bubble especially if you’re not sure where the water came from. You shouldn’t try popping water bubbles on your own if you recently had water damage from a sewage backup. Given the high probability of coming across further contaminants in water, seek help from a professional restoration service.
  • Popping big bubbles. Do not try popping a big or sensitively positioned water bubble on your own, such as one that is near electrical fixtures or in the ceiling. Instead, for extra help, get in touch with a water damage professional.
  • Repairing rapidly. It is necessary to drain the area and let it dry fully after a water bubble appears. You risk having the same issue again if you hurry this procedure or paint on a surface that is still slightly damp.


How To Prevent Paint Bubbling

Use the following tips to prevent paint bubbling and expensive repairs:

  • Before painting, all surfaces should be cleaned and ready.
  • Before painting, always ensure that the surface is dry.
  • Water-damaged areas should be repaired by a professional before painting or refinishing.
  • Make use of premium paint that has been expertly thinned or diluted.

·        Primer should always be applied to surfaces that have previously been coated with oil-based paint.
