During installation, make sure to secure the new drywall with drywall screws. Drywall clips can help anchor the new section to the existing wall, ensuring stability and alignment.

Refinishing and Texture Matching

After the new piece of drywall is installed, the repair process continues with the application of joint tape over the seams. This creates a smooth connection between the new and old sections.

Then, apply a layer of joint compound over the tape. Refinishing involves allowing the compound to dry completely before meticulously sanding it to achieve a texture that matches the surrounding area.

Finalizing With Painting and Trim Work

The final stage involves painting the repaired area to match the rest of the wall.

Materials like primer and paint should be carefully selected to complement the wall color and sheen, avoiding visible discrepancies.

Trim work is reinstalled or touched up as needed to create a seamless transition from the repaired section to the surrounding structure, ensuring the area shows no signs of previous swelling, sagging, or cracks.
