Identifying Bulging Drywall Seams

Drywall Seams Bulging

Drywall is a popular wall and ceiling material that is relatively economical, but it can suffer from bulging seams as the material ages. It occurs when the joint tape separating two parts of drywall becomes loose or damaged over time, causing the seams to bulge or crack. Bulging drywall seams are visually unappealing, and they can lead to unsightly surfaces and even structural damage if left untreated.

It is crucial to address bulging drywall seams before they become a significant problem. Identifying bulging drywall seams can be done quickly and easily with the following tips:

1. Check the Wall or Ceiling

Check the Wall or Ceiling

If you notice any bulges or protrusions on your wall or ceiling, it is essential to inspect these areas for damage or loose tape. It is also a good idea to examine the seams between the sheets of drywall to see if they are raised or visible.

Once you spot a bulging seam, run your hand over the area lightly. If it is indeed bulging, you will feel the tape or mud underneath the joint paper, creating a small ridge or bump.

If the bulging is severe, you may notice visible cracks or sagging in the seam, indicating a more severe issue, such as structural movement or water damage.

It is crucial to contact a professional if structural damage is suspected, as ignoring it may lead to further issues and more expensive repairs.

2. Look for Water Damage

Water Damage

Bulging drywall seams can also occur due to water damage or dampness. Excess moisture in a room can cause the drywall to swell and the seams to bulge.

If there are any signs of water damage, such as staining or cracking around the seam, you’ll need to address both the water issue and the bulging seam. Leak repairs or proper ventilation might be required to fix the underlying problem.

3. Inspect Seams around Windows and Doors

Windows and doors are common areas for bulging seams due to changing temperatures and movement in the building. The drywall may expand or contract, resulting in bulging seams around these areas.

If there is noticeable damage around your windows and doors, gently press the seam with your finger, and if it feels raised, the tape may need to be resecured or replaced to repair the bulging.

4. Check for Poor Installation Techniques

Poor Installation Techniques

Bulging seams can often be a result of poor installation techniques during the drywall installation process. If the joint compound or tape was not applied thoroughly, it may become loose over time, causing the seams to bulge.

If you suspect the seams are bulging due to installation issues, it is best to contact a professional to fix the issue and avoid the same issue in the future.

In conclusion, identifying bulging drywall seams can be done by visually inspecting the wall or ceiling, examining seams, checking for water damage, checking seams around windows and doors, and looking for poor installation techniques. If you detect these issues, it’s best to contact a professional to fix the issue before it becomes a significant problem.

Causes of Bulging Drywall Seams

Causes of Bulging Drywall Seams

It’s not uncommon to find bulging drywall seams in older homes or those with poor construction quality. While these seams may seem like a minor issue, they can quickly turn into a major problem if left unaddressed. That’s because while the seams are bulging, moisture can seep through, leading to further damage and even mold growth.

So, what causes bulging drywall seams? Here are a few probable causes:

1. Poor Installation: One of the most common causes of bulging drywall seams is shoddy installation. If drywall panels aren’t installed correctly, they can develop wrinkles or dips, which can cause the seam to bulge over time. Also, if the panels aren’t nailed securely, they can shift or sag, leading to bulging seams.

2. Moisture: Moisture is another significant cause of bulging drywall seams. If the drywall isn’t adequately protected from moisture, it can absorb water, leading to swelling and bulging seams. This issue is often seen in basements, bathrooms, and other areas where there’s excessive moisture in the air.

3. Temperature Changes: Temperature changes can also cause drywall seams to bulge. When temperatures fluctuate, the drywall can expand and contract, leading to bulging seams. This issue is particularly common in homes with poor insulation or those that experience extreme temperature changes.

4. Settlement: Over time, homes settle, and this can cause drywall seams to bulge. Settlement can be caused by various factors, including poor soil conditions, foundation issues, and natural disasters like earthquakes.

5. Structural Damage: In some cases, bulging drywall seams can be a sign of underlying structural damage. If the walls are damaged or compromised in any way, they may shift or move, leading to bulging seams. Structural damage can be caused by various factors, including water damage, fire damage, and human-made damage.

Now that you know what causes bulging drywall seams, it’s time to learn how to fix them properly. Read on for our expert tips on fixing bulging drywall seams.

Fixing Bulging Drywall Seams

Fixing bulging drywall seams is a simple task that can easily be done with the right tools and materials. Before you begin, make sure you have all the necessary tools and materials in order to ensure the job is done correctly, efficiently, and with as little mess as possible. Here are what you will need:

Drywall Tape

Drywall Tape

Drywall tape is a reinforced paper or fiberglass tape that is used to cover and seal the joints of the drywall. You can purchase drywall tape from any hardware store for under $10. Make sure to purchase the right tape for the job depending on the size of the seam. If the seam is larger than a quarter of an inch, purchase a wider drywall tape.

Drywall Compound

Drywall Compound

Drywall compound, also known as joint compound, is used to fill in the seam and hide the joint line. The compound is usually sold in a bucket for under $20. Make sure to purchase a pre-mixed one for ease of use. You will also need a putty knife to spread the compound over the tape and mask the seam. The size of the putty knife will depend on the size of the seam, with a larger one needed for bigger seams.

Sanding Block

Sanding Block

A sanding block is used to smooth out the surface of the drywall after the joint compound has dried. You can find sanding blocks in any hardware store for under $5. Sanding blocks come in different grades of roughness, choose a fine-grained sanding block for finishing work.

Primer and Paint

Bulging drywall seams are a common problem in older homes or those affected by humidity changes. The issue usually presents itself as a visible crack that has expanded as the joint compound shrinks or separates from the drywall tape.

The best way to fix bulging drywall seams is to remove the old tape and joint compound and apply new materials properly. Here is a step-by-step guide on how to fix bulging drywall seams:

Step 1: Remove Old Tape and Joint Compound

Removing Old Tape and Joint Compound from Drywall

The first step to fixing bulging drywall seams is to remove the old tape and joint compound. Use a putty knife to scrape the old joint compound from the seam until it is even with the drywall surface. Then, use a utility knife to cut along the center of the seam, cutting through the tape and removing it from the wall. Be careful not to cut too deep and damage the drywall paper underneath.

Step 2: Clean and Sand the Area

The final step is to apply a finishing coat of joint compound, using a wider putty knife to spread the compound smoothly over the seam and surrounding area. Once dried overnight, sand the surface with 220-grit sandpaper to remove rough edges and create a smooth surface. Finally, finish the seam with a drywall texture to help match the surrounding surface. There are many types of textures available, including spray-on, brush-on, or roll-on.

It’s important to note that fixing bulging drywall seams can be challenging, especially if you don’t have experience with drywall repairs. If you’re not comfortable tackling this project on your own, it’s best to hire a professional contractor to ensure the job is done properly and to avoid costly mistakes.

In conclusion, by following these simple steps you can easily repair bulging drywall seams in your home. Remember, it’s always best to take your time and be patient to achieve the perfect finish. Happy repairing!

Finishing Touches and Painting

Finishing Touches and Painting

After successfully repairing the bulging seams, the final step is to finish the job with proper painting techniques. Painting the affected area with the right tools and techniques can enhance the overall look of your walls and prevent bulging from reoccurring.

The first step is to choose the right primer. Priming is critical to creating a smooth paint surface and helps the paint adhere to the walls. A top-quality primer should be used to ensure the paint sticks to the walls properly. Professionals suggest using an oil-based primer over water-based primer. Oil-based primer is beneficial because it delivers a nicely evened finish and creates a better quality bond with the surface of the wall.

The next thing to consider is the quality of the paint being used. The paint quality determines the overall finish of your wall. So make sure to choose a paint brand and color combination that will complement your walls. The paint quality also plays an important part in elasticity, texture, and durability. Choose a paint that is suited for the room’s environment. For instance, if you are to paint the bathroom walls, consider using paint with a moisture-resistant formula suitable for high humidity conditions.

After deciding on the primer and paint, you are ready to start painting the repaired area. Use a high-quality brush to paint, starting from the center of the repair area and moving towards the edges. A small paint roller is also an excellent alternative for painting the entire wall. Consider selecting a roller cover with a ⅜-inch nap for drywall surfaces.

For the first coat, apply a thin layer of paint gently to the affected area. Do not paint over the joints and try not to overwork the paint. Wait for the paint to dry completely as per the manufacturer’s instructions. Generally, it takes 2 hours to dry oil-based paint and 1 hour for water-based paint. Once completely dry, lightly sand the surface, then wipe off dust and debris with a damp cloth. Make sure the surface is smooth to the touch before applying the finishing coat.

When applying the second coat of paint, concentrate on achieving rich color and even coverage on the walls. Allow it to dry again with patience before applying a possible third coat if required. Once the final coat is dry, step back and admire your newly repaired and painted walls.

It is worth noting that painting is a time-consuming task, so don’t rush the process. Take your time, allowing each coat of paint to dry correctly before applying the next one. This will help to produce a quality finish that will last for years, ensuring the bulging drywall seam problem will not come back.

Moreover, remember that paint fumes can be harmful to your health. It is best to work in a well-ventilated area to avoid inhaling fumes. Cover the floor with a drop cloth or paper tarp to protect it from paint splatters. Also, be sure to remove the painter’s tape before the paint dries completely to prevent the tape from peeling the paint off the wall.

In conclusion, repairing the bulging seams and painting your walls properly can significantly enhance the appearance of your home. With proper techniques, you will enjoy a smooth surface and beautiful walls without the worry of seams bulging again. So, follow the steps mentioned above, and your walls will be looking amazing in no time!
