"USA Insulation came out and blew in the pink stuff up to R49. The crew arrived on time, was professional and very thorough with what they were going to do before starting, communicating during of their progress and then a 'show and tell' after the work was completed. Cleanup afterwards let my house cleaner than before they showed up and only took them around 1 1/2 - 2hrs from start to finish (for a 1425 sq ft attic). The entire process, from start to finish, exceeded my satisfaction and we will most certainly be recommending USA Insulation to our friends and family."

Drywall Insulation questions, answered by experts

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

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.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

Vinegar and bleach are effective options for removing mold from drywall. Vinegar is a better choice if you have a smaller mold issue while bleach is best if you have a larger mold problem. If the area you're cleaning has limited ventilation, using vinegar would be a better option. In that case, you could mix vinegar with baking soda to remove more stubborn mold growth.

Popular wall textures include orange peel, knockdown, spray sand, and smooth finishes. Orange peel and knockdown are particularly common choices for drywall as they are simple and cost-effective. Orange peel texture has a lightly bumpy surface resembling the skin of an orange, while knockdown (sometimes called knockout) looks like a stucco finish with flattened high spots. In contrast, popcorn texture has fallen out of fashion, partly due to its past association with asbestos and a shift toward more restrained interior design styles.
