The inevitable question: How to fix drywall cracks and holes?

Hey everyone, I've got a few hairline cracks that have appeared in my living room drywall, and a small hole from where I accidentally knocked something into it. I'm looking for the best methods and materials to make these repairs look seamless. I've heard about joint compound, spackle, and mesh tape, but I'm not sure which is best for different types of damage. Any tips on achieving a smooth finish that will blend in with the existing paint?

Specifically:

• What's the difference between all-purpose joint compound and lightweight spackle?
• When should I use paper tape versus mesh tape for cracks?
• What's the best technique for feathering out the compound to avoid visible patches?

Appreciate any advice you can share!

Re: Fixing Cracks and Holes in Drywall

Hi HandyAndy! Good question. Drywall repair is a common task. For hairline cracks, a good quality lightweight spackle is usually sufficient. It's easy to sand and dries relatively quickly. For larger cracks or small holes (up to an inch or two), I prefer using a fiberglass mesh tape and a few thin coats of all-purpose joint compound.

The key to a seamless finish is patience and thin coats. Apply the first coat of compound over the tape/hole, pressing it through the mesh. Let it dry completely. Then, apply a second, wider coat, feathering out the edges. You might need a third coat for a perfectly smooth surface.

Always sand lightly between coats with a fine-grit sandpaper (150-220 grit) to knock down any high spots and ensure smooth transitions. Prime the repaired area before painting to ensure the paint adheres evenly and doesn't show a sheen difference.

I had a similar issue with a hole about the size of a golf ball. I used a self-adhesive drywall patch kit, which is basically a metal plate with mesh. You just stick it over the hole, then apply joint compound over it in thin layers. Worked like a charm for me, and I'm not very experienced!
