Spackling is an easy method for patching holes in drywall. Usually, a thin layer of spackle is spread over the hole or crack using a flat-edged putty knife. Avoiding and removing bumps in drywall spackle after patching up the wall is a straightforward process that involves few steps.
Use an appropriate amount of spackle
The amount of spackle should be enough to cover the crack or hole. Spread the spackle over the crack or hole, and make sure that a small, 1-to-2-inch area of the surrounding wall is also covered. House-Painting-Info.com recommends using a fiberglass mesh tape to cover the affected area before applying the spackle. This ensures that the amount of spackle applied is sufficient with respect to the crack. Leave the wall overnight to dry.
Level the spackled surface
Once dry, sand the spackled wall using a fine granite sanding paper to smooth out the newly dried spackle, and even it out with the wall. After the sanding is complete, check the wall for unevenness by running a hand over it. If unevenness persists, another coat of spackle may be required.
Cover the spackled area with paint
After the speckle is completely dry, use a primer to even out the color of the repaired area with the surrounding area. As the primer dries off, apply the final paint that matches the rest of the wall.
