Get matched with top plaster repair specialists in Columbus, TX

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

It is possible to repair plaster walls yourself, but it’s not always a good idea. Hiring a professional means you’ll have expert eyes on the damage looking to see if there is an underlying issue or if the cracks are just from normal expansion and contraction. Additionally, a professional’s plaster repair will very likely last longer than a DIY job, which means you could end up saving money over time by going with a pro from the start.

Small hairline cracks in plaster walls are not serious and are mostly cosmetic, but larger or widespread cracks indicate structural problems that need repair. 

• Cracks 0.5 cm (0.2 inches) or thinner: Cosmetic cracks you can repair if desired.

• Cracks wider than 0.5 centimeters or widespread cracks: Structural repair is needed, either DIY or by a pro.

• Cracks 2.5 centimeters (1 inch) or wider: Contact a plaster repair professional.

Watch for large, deep cracks, multiple cracks in the same area, and cracks along the walls where they meet the ceiling. Repair these cracks to prevent further damage.

You can apply plaster over plaster, but before you do, check the stability of the existing plaster. If it’s been there for a while, it may require a base coat of PVA emulsion. This will make the existing plaster less porous and ensure the new and old plaster adhere properly.
