Step-by-Step Guide to Drywall Repair

1. Repairing Small Holes and Cracks (Under ½ Inch)

For tiny nail holes and hairline cracks, follow these simple steps:

1️⃣ Apply Joint Compound (AKA: Spackling Paste) – Use a putty knife to spread a thin layer.
2️⃣ Smooth It Out – Scrape away the excess for a flush finish.
3️⃣ Let It Dry – Check the label for drying time (usually 30–60 minutes).
4️⃣ Sand Gently – Use fine-grit sandpaper to create a smooth surface.
5️⃣ Prime & Paint – Once smooth, apply primer and repaint the area to match.

💡 Pro Tip: For a seamless finish, lightly feather out the edges of the patch when applying spackling paste.


2. Fixing Medium-Sized Holes (1–4 Inches)

For holes too large for spackle alone, a drywall patch kit is your best friend.

1️⃣ Prepare the Hole – Trim rough edges using a utility knife.
2️⃣ Apply a Self-Adhesive Patch – Stick the patch over the hole.
3️⃣ Cover with Joint Compound – Spread a thin layer over the patch, feathering the edges outward.
4️⃣ Let It Dry & Repeat – Apply 2–3 thin coats, allowing each layer to dry before sanding.
5️⃣ Sand, Prime & Paint – Once smooth, prime and paint to blend with the wall.


3. Patching Large Holes (4+ Inches)

For bigger holes, you’ll need to cut and replace a piece of drywall.

1️⃣ Cut a Drywall Patch – Use a new drywall piece that fits the hole.
2️⃣ Secure It with Backing – Attach a wooden brace behind the hole to support the patch.
3️⃣ Tape & Mud the Seams – Apply joint tape around the edges, then cover with joint compound.
4️⃣ Sand & Finish – Once dry, sand it smooth and repaint the area.

💡 Pro Tip: Use lightweight joint compound for easier sanding and a smoother finish.
