How To Tape Inside Drywall Corners

Properly taping inside drywall corners is a crucial step in creating a smooth and professional-looking finish. It prevents cracks and unsightly gaps and ensures a seamless transition between drywall panels. This article will guide you through the essential aspects of taping inside drywall corners, providing step-by-step instructions and tips for achieving the best results.

Essential Aspects:

Corner Tape Selection: Choosing the right corner tape is vital. Fiberglass mesh tape is the most common and suitable for interior corners, while metal corner bead is more durable and typically used for exterior corners.
Corner Preparation: Before applying corner tape, ensure the drywall corners are clean, dry, and free of any debris or dust.
Tape Application: Center the corner tape over the corner and firmly press it into place. Ensure the tape is fully adhered to the drywall surface.
Joint Compound: Apply a thin layer of joint compound over the corner tape. Smooth it out using a drywall knife, ensuring it covers the edges of the tape.
Second Coat: After the first coat has dried, apply a second coat of joint compound and smooth it out again. This coat should be slightly wider than the first and extend slightly beyond the tape.
Sanding: Once the joint compound is fully dry, sand the surface smooth. Use fine-grit sandpaper to avoid damaging the drywall.
Priming and Painting: Apply primer to the taped and sanded corners to seal the surface. Once the primer has dried, you can apply paint to match the rest of the wall.

Conclusion:

Following these essential aspects will help you achieve a professional-looking finish when taping inside drywall corners. By carefully preparing the corners, selecting the appropriate tape, and applying the joint compound correctly, you can prevent cracks and create a smooth and durable surface that will enhance the overall appearance of your drywall installation.
