Fix Cracks in Walls, paints are more than just an eyesore — they can signal deeper issues like surface stress, moisture, or poor paint adhesion. Luckily, with the right repair products such as fiberglass drywall joint tape and wall putty, you can restore your walls to a smooth, durable finish.
Why Do Cracks Appear in Wall Paint?
- Moisture Damage – Damp walls weaken paint and plaster, leading to cracks.
- Poor Surface Prep – Painting over dust, grease, or old flaking paint reduces adhesion.
- Structural Movement – Natural settling of walls can cause hairline cracks.
- Low-Quality Paint – Cheap paints lack flexibility and crack more easily.
How to Fix Cracks in Walls
1. Clean & Prepare the Surface
Scrape away loose paint and dust. Ensure the wall is dry before repair.
2. Apply Fiberglass Drywall Joint Tape
- Place the fiberglass mesh tape directly over the crack.
- This reinforces the surface, preventing cracks from reappearing.
- Unlike paper tape, fiberglass is self-adhesive, strong, and flexible.
3. Cover with Wall Putty
- Apply a thin layer of wall putty over the tape using a putty knife.
- Smooth it out evenly and let it dry.
- For deeper cracks, apply a second coat.
4. Sand & Prime
Once dry, sand the surface for a smooth finish. Apply primer to seal the repair.
5. Repaint with Quality Paint
Choose a durable paint brand to ensure long-lasting results.
