Bad Drywall Job – How to Fix It: A Comprehensive Guide

Drywall is a popular choice for walls and ceilings due to its affordability, aesthetic appeal, and fire-resistant properties.

However, a poorly executed drywall installation can lead to several issues, including uneven surfaces, visible joints, nail and screw holes, and crumpled corner beads.

These imperfections not only compromise the appearance of your home but can also pose safety risks.

In this comprehensive guide, we will explore the causes of a bad drywall job and provide step-by-step solutions to fix each problem.

What is Drywall?

Drywall, also known as gypsum board, sheetrock, or wallboard, is a panel made of gypsum plaster sandwiched between thick paper.

It serves as a sheathing material for interior walls and ceilings, replacing the traditional lath and plaster.

The use of drywall offers a more efficient and cost-effective alternative to wet plaster installation, making it a popular choice in residential and commercial construction.

Benefits of Drywall

If you’re considering drywall for your home, here are some compelling reasons to choose it over other construction materials:

  1. Affordability: Drywall is more budget-friendly compared to plastic walls and panels, making it an economical choice for many homeowners.
  2. Aesthetically Pleasing: Drywall’s smooth and versatile surface allows for endless design possibilities. It can be painted multiple times, enabling you to achieve the desired aesthetic appeal.
  3. Insulation: Drywall provides excellent insulation, helping to maintain the desired temperature in your home and improve energy efficiency.
  4. Fire-Resistant: Safety is a top priority for homeowners, and drywall offers peace of mind with its fire-resistant properties. It contains additives that enable it to withstand fire or slow down its spread.
  5. Easy Installation and Repair: Drywall installation is relatively straightforward for professionals with experience and the right tools. Additionally, repairing a bad drywall job is relatively easy, even for inexperienced individuals.

Common Drywall Problems and Fixes

Common Drywall Taping Mistakes

1. Uneven Drywall

Uneven drywall can be a significant eyesore if not addressed promptly. Even the slightest differences between sheets can become more visible over time.

Fortunately, there are effective techniques to fix this problem, such as skim coating.

How to Fix Uneven Drywall:

  1. Start by sanding the specific uneven area of the drywall, rather than the entire wall. Use a sanding pole for hard-to-reach higher areas.
  2. Apply polyvinyl acetate (PVA), a primer-sealer, to the sanded area and allow it to dry. PVA helps create a more uniform surface.
  3. In a five-gallon bucket, mix water and all-purpose joint compound powder until it reaches a consistency similar to peanut butter.
  4. Spread the mixture in a mudding trough and apply it to the uneven areas of the drywall using a flat drywall knife. Use the knife to eliminate visible seams and ridges, applying multiple coats if necessary.
  5. Allow the compound to dry completely, then sand the area until the drywall is smooth and even.

2. Visible Joints

Proper drywall installation should result in seamless connections between panels.

However, visible joints can occur due to improper installation or shifting of panels over time. Fortunately, there are several ways to fix this issue.

How to Fix Visible Joints:

  1. Use all-purpose mud to coat the visible joints. Start with a four-inch drywall knife for the first coat, then switch to a six-inch knife for subsequent coats. Gradually widening the knives helps seal the joints and create a flatter appearance.
  2. Allow each coat to dry overnight before applying the next one. Once the final coat is dry, sand it with 120-grit sandpaper.
  3. Alternatively, drywall tape can be used to cover the joints. Apply the tape over the joint, pressing it firmly into the compound. Use a knife to flatten any bubbles and ensure a smooth finish.
  4. To further hide visible joints, consider using matte or dark paint. These finishes can help conceal any flaws that may be more apparent under bright lighting. Applying a thick coat of paint can also help hide the joint.
  5. Another option is to cover the drywall with wallpaper, preferably a thick textured variety. This can effectively camouflage visible joints and add visual interest to the wall.

3. Nail and Screw Holes

During the installation of drywall, nails or screws are used to secure the panels in place.

However, these fasteners can leave behind visible holes or even pop out over time.

Fortunately, filling these holes is a simple fix.

How to Fix Nail and Screw Holes:

  1. Begin by sanding the surface around the hole to smooth out any protruding material. Use a knife to cut away any excess material.
  2. Purchase a high-quality spackling paste specifically designed for filling nail or screw holes. Apply the paste to a putty knife and fill the hole, swiping downward or sideways to remove any excess paste. For larger holes, multiple layers may be required.
  3. Allow each layer to dry completely before applying the next one. Once the final layer is dry, sand the area until it is smooth and the hole is no longer visible.
  4. Finish by painting the surface to match the surrounding area or leave it bare, depending on your preference.

4. Crumpled Corner Bead

Corner beads are L-shaped metal strips that provide a smooth connection between two drywall panels at a corner.

However, poor construction or accidental damage can cause the corner bead to crumple, compromising the integrity of the surrounding area.

Repairing a crumpled corner bead requires replacing the damaged section.

How to Fix Crumpled Corner Bead:

  1. Mark the damaged section of the corner bead and carefully cut it using a fine-toothed hacksaw. Be cautious not to damage the surrounding area, as this can be fixed later.
  2. Remove the damaged section of the corner bead by prying it out.
  3. Measure the replacement section of the corner bead and cut a new metal bead based on the measurements.
  4. Smooth the edges of the new corner bead using a metal file. Position the new bead and secure it using screws or nails.
  5. Apply drywall compound along the bead, ensuring a smooth finish. Allow the compound to dry, then sand the area until it is smooth and visually appealing.

By following these steps, you can fix a bad drywall job and restore the beauty and functionality of your walls and ceilings.

Tips and Tricks for Proper Drywall Installation

How to fix bad drywall job

To prevent a bad drywall job and minimize the chances of encountering aesthetic problems, consider the following tips:

  1. Use a Drywall Lift: If you’re installing drywall on the ceiling, use a drywall lift to make the process easier. A DIY lift can be constructed using a riser pipe, or you can rent one. This eliminates the need for manual holding, allowing for more precise positioning of the drywall.
  2. Opt for Smaller Drywall Cuts: When installing drywall yourself, opt for smaller cuts to make handling easier. This reduces the need for frequent cutting and ensures a more efficient installation process.
  3. Seal Exposed Areas: Seal any exposed areas of the drywall to prevent future problems such as cracks and visible joints. Sand the surface to achieve a texture similar to the rest of the wall before applying the sealant.
  4. Nail on a Rigid Structure: Ensure the drywall is securely fastened to a rigid structure to provide the necessary support. Failing to do so may result in the drywall becoming dislodged when subjected to force.
  5. Choose the Right Nails and Screws: Use nails and screws that are suitable for drywall installation, considering factors such as size and quality. Using the wrong fasteners can compromise the structural integrity of the drywall.
  6. Work with a Professional: If you lack the knowledge and skills to install drywall correctly, it’s advisable to work with a professional. The expertise and experience they bring can save you time, effort, and potential mistakes.
