Cracks in walls can be a real eyesore, especially when you’re planning on painting the room. Fortunately, fixing wall cracks before painting is a relatively simple process that can be accomplished with a few basic tools and materials. In this article, we’ll walk you through the steps of how to fix wall cracks before painting.

Step 1: Clean the Area

The first step in fixing wall cracks before painting is to clean the area around the crack. This will ensure that the repair material adheres properly and that there is no dust or debris that will interfere with the repair. Use a soft-bristled brush or a vacuum cleaner to remove any dust or debris from the crack and surrounding area.

Step 2: Assess the Severity of the Crack

Before you begin the repair process, it’s essential to assess the severity of the crack. If the crack is less than 1/8 inch wide, it’s considered a hairline crack and can be easily repaired with paintable caulk or spackling compound. If the crack is wider than 1/8 inch or if the wall is bulging or uneven, you will likely need to use a more robust repair material, such as joint compound or epoxy.

Step 3: Fill the Crack

Once you’ve determined the appropriate repair material, you can fill the crack. If you’re using caulk or spackling compound, use a putty knife to fill the crack with a thin material layer. If you’re using joint compound or epoxy, use a drywall knife or putty knife to apply a thick layer of the material to the crack.

Once you’ve filled the crack, you will need to allow it to dry completely. Depending on the material and humidity, this can take anywhere from an hour to several days. Read the instructions on the repair material you use for a more accurate drying time.

Step 4: Sand the Area

After completely drying the repair material, you’ll need to sand the area to smooth out any rough spots. Use fine-grit sandpaper to gently sand the area until it is smooth and flush with the surrounding wall. If you are using joint compound, you may need to apply another coat after the first coat is dry, to ensure that the area is filled and smooth.

Step 5: Prime the Area

Before you begin painting, it’s essential to prime the repair area. This will help to seal the repair and ensure that the paint adheres properly. Use a paintbrush to apply a coat of primer to the repair area, and make sure to feather the edges to blend the repair seamlessly with the surrounding wall.

Step 6: Paint the Area

After the primer is dry, you can finally paint the area. Use a paintbrush and roller to apply paint to the repair area and to the surrounding wall. It’s essential to paint the entire wall to ensure that the color is consistent and that the repair is not noticeable.

And you are done! It might seem like a lot of steps, but it’s easy to fix wall cracks before painting with patience and the right materials. Remember to take your time and carefully follow each step to ensure that the repair is seamless and that the wall is ready for painting.

Tips: -Always use paintable caulk. Regular caulk will not work for this. -If the crack is larger than 1/8 inch, it might be a sign of a bigger problem. In such case, it’s better to call a professional to check the cause and provide an appropriate solution.
