Determining Severity
How deep is the crack? Can you fit a coin inside? If it’s shallow, it’s minor. If it’s deep, it’s serious. Are there many cracks? Do they form a pattern? A single, small crack is easy. Multiple, large cracks are different. Watch for crumbling plaster. This means a bigger problem.

Matching Paint Color
Finding the right paint color matters. You want a perfect match. Look at your existing wall paint. Take a small chip to the store. Paint stores can match your color. They use a special machine.
