How to Repair Uneven Drywall

Seams, ridges, valleys, and residues on a wall disrupt continuity and are not an attractive sight. Uneven drywall or plasterboard is a result of either a wet or buckled wall, removing wallpaper, or improper installation. Thankfully, DIYers can fix uneven drywall with a few materials and simple steps. With a texturing technique that professionals call 'skim coating', DIYers achieve smooth and seamless walls when done correctly. Although it employs basic materials and simple steps, skim coating requires a certain level of expertise to do efficiently. Beginners should expect to spend more time repairing uneven drywall. However, at relatively slow and careful pacing, DIYers can still find fulfillment in being able to repair their own uneven drywall.

1. Preparing the Materials

DIYers need to attend to the task with complete tools and materials, beginning by assembling a number of items. These items include 120-grit sandpaper; a sanding pole; PVA primer; drywall compound and compound pan; a 10- to 12-inch drywall knife; and a drywall sounding sponge (optional).

2. Sanding

Using 120-grit sandpaper, sand the wall to eliminate residue and bumps due to removing the wallpaper. DIYers can reach high areas on the wall and the ceiling by using a tool or, more effectively, using a sanding pole. When sanding, remember to veer away from seams where the paper tape is visible.

3. Applying PVA Primer

After sanding the all the areas, apply a coat of PVA primer on the wall and allow it to dry completely. It is advisable to use polyvinyl acetate, which is a prime sealer that aids in making the wall surface uniform, thus making for a more even working surface.

4. Drywall Compound Options

DIYers have the option of buying a ready-mixed compound or mixing their own. When mixing a drywall compound, mix a batch of all-purpose drywall compound or joint finish with water in a 5-gallon (19-litre) bucket. The mixture should have the consistency of jam-not pourable and staying on the mixing tool without falling off.

5. Applying the Drywall Compound

With a 10- to 12-inch taping knife, scoop a mound of the compound. Keep the mound of compound near the centre and edge of the taping knife's blade. Apply the compound into depressions in the drywall and scrape it flat with the knife. Spread the compound on either side of ridges and visible seams on the wall.

First, fill the largest portion of the seam's gap with the compound and press the knife with mound of compound onto the seam, drawing the knife across the seam's length. Then, fill the deepest part of the gap with the first coat. Remember to not apply a broad layer of compound on the first coat and to not attempt to make the gaps disappear on the first coat. It may take several coats to completely cover gaps, especially the larger ones.

6. Applying the Second Coating of the Compound

When the first coating is already dry, it is time to apply the second coating. For the second coat, place the mound of compound across the breadth of the knife's edge. This time, spread a broad layer across the length of the seam, especially on the side that dips. Take the excess compound from the wall and put it back into the pan. Completely remove the compound from the knife by scraping the blade on the side of the pan. Then, run the knife across the seam to even out the wet compound. Smooth all sides of the second layer before tapering the edges for a smooth transition between the new compound and the existing wall. Let the second layer of compound dry completely.

7. Finishing Touches

With a damp drywall sanding sponge, gently press along the edge of the repair area while rotating the sponge in a circular motion. Smoothen the edges of the repair area and blend its transition with the existing wall. The new compound may form a peak over the seam, and the sanding sponge can flatten the peak and blend it with the compound around it. DIYers can also opt for a 120-grit sandpaper when sanding the wall lightly after the final coat dries. As a reminder, prime the wall with PVA primer before applying paint.

8. Additional Tips

When repairing an uneven drywall, DIYers may encounter some problems. There are a number of simple steps with which DIYers can avoid or correct these problems.

Issue

Tips

Uneven Wall Due to Drywall Getting Wet

Make sure that the wall is completely dry and firmly attached to the studs before skim coating

Non-matching Texture

To match a texture, apply aerosol drywall texture after applying the final coat of the compound

Following the tips helps make repairing uneven drywall a success for many DIYers. However, badly damaged drywall is more likely to require replacement than repair.

How to Buy Repair Items for Uneven Drywall on eBay

eBay lists a broad range of repair items for uneven drywall, and buyers can begin the search by typing keywords into the search field of the site. Buyers should actively search for listings with free postage to save money, and these offers may come from top-rated sellers of the site. Buyers can also visit eBay Deals to find more discounted items.

Beginners do well to buy a pre-mixed drywall compound to make the process easier. The first coating of the compound does not cover the depressions, and DIYers may need to apply several coatings, especially in larger depressions. However, despite the many steps of repairing an uneven drywall, DIYers who know how to do it can save money and have a sense of fulfillment upon completing the job.
