Q: Can I just paint over hairline cracks in plaster?

• <div><p>You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.</p></div>

Q: Why hire a professional for wall repair?

• <div><p>Ensures structural integrity and aesthetic consistency with proper materials and techniques.</p></div>

Q: What is the lifespan of plaster walls?

• <div><p>Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.</p></div>

Q: What is the difference between spackle and joint compound, and which should be used for drywall repair?

• <div><p>Although they are used for similar tasks, spackle and joint compound are not the same. Joint compound, also known as drywall mud, consists of limestone and gypsum and is primarily used for large-scale projects like taping and finishing seams on new drywall. Spackle is composed of gypsum and binding agents, making it a thicker compound best suited for small wall repairs like filling nail holes or cracks, as it dries quickly and is easy to sand. For small repairs, either product can be suitable. However, you can use joint compound for small jobs in place of spackle, but you cannot use spackle for large-scale taping and mudding projects.</p></div>

Plaster Repair questions, answered by experts

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.
Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.
