DIY – How to Fix Cracks Around Window Frames
- Inspection and Preparation
- Assess the severity and type of crack.
- Clean debris or loose material using a scraper or utility knife.
- Apply Joint Compound or Spackle
- For hairline and minor vertical cracks, use lightweight spackle.
- Apply drywall joint compound or mud for larger cracks (horizontal, diagonal, stair-step).
- Reinforcement
- This is needed for larger or recurring cracks. Embed fiberglass drywall tape over the initial layer of joint compound. You get additional strength. It also provides flexibility to help prevent recurring cracks.
- Sanding and Finishing
- Sand the dried compound smoothly using medium-fine sandpaper (120 to 220 grit).
- Apply additional layers as needed, sanding each coat until flush with the surrounding surface.
- Priming and Painting
- Apply a primer coat. Primers help the next layer of paint stay put and not peel.
- Paint with matching interior paint and feathering edges for seamless blending.
