Are cracks in plaster walls serious?

• <div><p>All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes.

Q: Will Venetian plaster increase the value of your home?

• <div><p>Whether Venetian plaster increases your home's value often depends on the buyer's preference. As a purely aesthetic upgrade, it doesn't add structural value in the same way a kitchen or bathroom remodel might. However, its beautiful and attractive appearance can make a home more appealing to potential buyers, possibly leading to more interest, higher offers, and increased competition when you sell.</p></div>

Q: Can you plaster over broken plaster?

• <div><p>It&rsquo;s not a good idea to plaster over broken plaster (unless by broken you&rsquo;re referring to cracked, in which case that&rsquo;s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it&rsquo;s worth investigating before you simply plaster on top of the damage. </p></div>

Q: Can you apply new plaster over an existing plaster surface?

• <div><p>Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.</p></div>

Q: How much coverage is one gallon of Venetian plaster?

• <div><p>This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques&ndash;like Scagliola&ndash;that requires several coats, expect the project materials costs to add up quickly. </p></div>

Plaster Repair questions, answered by experts

Whether Venetian plaster increases your home's value often depends on the buyer's preference. As a purely aesthetic upgrade, it doesn't add structural value in the same way a kitchen or bathroom remodel might. However, its beautiful and attractive appearance can make a home more appealing to potential buyers, possibly leading to more interest, higher offers, and increased competition when you sell.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly.

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.
