Filling cracks in your ceilings and walls is important to keep your home looking great and prevent future issues. But what is the best filler for cracks in plaster? To pick the best option for you, you’ll need to do a little research.
1. Hairline Cracks
Hairline ceiling cracks are very thin cracks – typically 1/16 th of an inch or smaller. In most cases, they are cosmetic in nature and while they may look unnerving, they are almost always not dangerous. These cracks are most commonly caused by old paint or plaster over drywall.
2. Brown or Yellow Cracks
If you have discolored cracks on your ceiling, this is usually a sign of a water leak. A yellowish or brownish tinge at the edges of a ceiling crack is an indication of moisture damage. In this case, you’ll want to start looking for water where it should not be. Before you repair the drywall, you must locate and address the leak.
How to Remove Drywall
Use a knife to cut away at the point where the molding meets the drywall. Then, use either a sledgehammer or a small mallet to carefully create holes in the center of the drywall. The goal is to avoid hitting the joists, otherwise you risk causing further structural damage.
How to Replace Ceiling Drywall

3. Spiderweb Cracks
As the name suggests, spiderweb cracks appear like spiderwebs and are usually caused by foundational settling or cracking paint or plaster. They have a central point, with thin cracks extending outwards in all directions. If the drywall was applied too thickly, it can result in thin, spiderweb-like cracking as it shrinks during the drying process.
4. Straight Cracks
Cracks in the ceiling that are essentially a straight line are usually a result of improper taping or mudding during drywall installation. If not enough mud was applied, the tape cannot stick properly to the joints and will start to pull away, causing a crack in the plaster.
5. Cracks Between Wall and Ceiling
If you have a crack in the spot between your ceiling and an adjacent wall, this is usually caused by truss uplift. Your roof trusses are designed to move and shift as the wood expands and contracts with changes in heat and humidity. It’s possible for the trusses to shift so much that it lifts the ceiling away from the wall.
