Why Sealing Cracks is Important
Sealing cracks stops problems:

- Sealing cracks helps keep your home strong. This care stops high repair prices later.
Types of Cracks and How to Seal Them
1. Wall Cracks
For hairline cracks, try painting or using spackle:
- Clean the crack with a brush. Remove dust and debris.
- Fill the crack with spackle using a knife. Smooth the spackle.
- Let it dry. Then sand it and paint over it.
For cracks wider than a quarter-inch, use a stronger filler:
- Widen the crack by cutting it in a V-shape. This helps the filler hold.
- Pack the filler into the crack. Use a knife to press it in firmly.
- Let it dry well. Then sand and paint the wall.
2. Concrete Cracks
For shrinkage cracks, use a patching mix:
- Clean loose concrete from the area.
- Mix the patching compound as directed. Fill the crack and smooth it with a trowel.
- Give the repair time to dry as the instructions say.
For cracks from movement, use a polyurethane sealant:
- Clear and widen the crack if needed.
- Push the sealant into the crack. Smooth the surface after.
- Change the surface if you need to match the rest of the concrete.
3. Foundation Cracks
Cracks in the base of your house can be serious. If you see horizontal cracks, ask a professional. For vertical or diagonal cracks:
- Look at the crack closely.
- Pour epoxy into the crack to fill it.
- Watch the crack over time for any changes.
