11 Step-by-step Guidelines on How to Fill Gaps in Garage Wall

Step 1: Clean the Area

Remove any dirt, dust or debris from the gap using a paint scraper or vacuum. This will ensure a smooth and clean surface for the filler to adhere to. It’s important to note that the gap should also be free of any loose or flaking material before proceeding. But don’t worry, this process will only take a few minutes! It’s worth the effort for a professional-looking finish.

Step 2: Prepare the Filler

For smaller gaps, use putty or joint compound. For larger gaps, mix drywall compound according to package instructions. Be sure to only mix enough for one application at a time as it dries quickly. You can always mix more as needed. Otherwise, you’ll end up with a hardened lump of filler that’s not usable. It’s also recommended to use a plastic putty knife or trowel for easy application.

Step 3: Apply the Filler

Using your putty knife or trowel, apply the filler in a smooth and even manner over the gap. Be sure to press firmly to ensure the filler fills any gaps completely.

If using a drywall compound, you can also embed drywall tape into the compound for added reinforcement. It’s important to note that the filler should be applied slightly higher than the surrounding surface to allow for sanding. It’s always better to have too much filler than not enough.

Step 4: Let the Filler Dry

Follow the instructions on the package for drying time. This typically ranges from 30 minutes to an hour. It’s important not to touch or disturb the filler during this time as it can affect the final result. It’s also recommended to work in a well-ventilated area for safety. The filler will become hard and white when it’s ready for the next step. It’s always better to wait a little longer than to rush and potentially ruin your hard work.

Step 5: Sand Down the Filler

Using medium grit sandpaper, gently sand down the dried filler until it’s level with the surrounding surface. This may take a few minutes, so be patient and take your time. It’s important to use a light hand and not apply too much pressure as this can create uneven surfaces or even damage the wall further. Once you’re happy with the level of the filler, switch to fine-grit sandpaper for a smoother finish.

Step 6: Wipe Away Dust

Using a clean cloth or tack cloth, wipe away any dust from the sanding process. This will ensure a clean surface for painting or further coats of filler if needed. It’s important to remove any dust particles as they can affect the final appearance of your wall. But don’t worry, this process only takes a few seconds. It’s always better to be thorough and ensure the best results.

Step 7: Apply Primer

For larger gaps or if you’re painting over the filler, it’s recommended to apply a coat of primer before proceeding. This will help seal any remaining cracks or imperfections and create a smooth surface for the paint to adhere to. Use a paintbrush or roller for an even application and be sure to let it dry fully before continuing.

Step 8: Paint the Wall

If you’re painting over the filler or the entire wall, no need to worry about perfectly matching the color of the surrounding surface. Simply paint over it with your desired color, making sure to cover the filler completely.

If you’re not painting, skip this step and proceed to the next. You may need to apply a second coat of paint for full coverage. It’s always recommended to use a paintbrush for corners and edges, and a roller for larger surfaces.

Step 9: Smooth Out Any Imperfections

After the final coat of paint has dried, inspect the wall for any remaining imperfections. If you find any, simply repeat steps 3-8 until you achieve your desired result. It’s important to take the time to do this extra step as it will ensure a flawless finish. You’ll thank yourself later when your wall looks like it was professionally done. It’s all about the details!

Step 10: Caulk Around Frames

If your gap is near a door or window frame, using caulk can help create a seamless finish. Simply cut the tip of the caulk tube at an angle and apply a thin bead around the edges of the frame. Smooth it out with your finger or a caulking tool for a clean and professional look. This step is not necessary, but it will give your wall a polished appearance.
