Drywall questions, answered by experts

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

If your premixed drywall mud is dried out or has begun to set in the bucket, you may be able to revive it by adding warm water and stirring. However, the first and most important step is to scrape off any hard, dried bits of drywall that may have accumulated toward the top of the container and throw them away because they will not easily reconstitute back into the drywall mud mix.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

Plaster that sags or bulges, shows extensive deep cracks, or is crumbling from water damage or simply time may need replacement. Plaster walls can look a little “worn” for a long time before they need replacing. The only real way to know if it needs a replacement is to hire a professional to assess the condition of the plaster.

In many cases, installing new drywall will boost your home value. Replacing old, damaged, cracked, or wavy drywall is a great way to improve the look and feel of your home, as new drywall installed by a professional shouldn’t have any imperfections. Additionally, removing old drywall means you’ll have open walls, so you can install new insulation and address exposed issues with plumbing and electrical systems running behind the walls. All of these fixes will also add to your home’s value.
