Drywall Insulation questions, answered by experts

Choose a drill bit that is the size of the screws of the anchors you will use. You aren’t drilling through metal or concrete—hopefully—so any standard twist, wooden or all-purpose drill bit will work fine. It’s also important to have a screwdriver capable of drilling through the drywall and into the stud. The good news is most available drills, even the older ones, can do this with no issue.

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.

Whether to repair or replace water-damaged plaster depends on the scale of the damage. For small, limited areas, you can often perform a repair yourself. If you choose to paint over small patches, ensure the surface is completely dry and apply a coat of antifungal primer first to prevent mold growth. However, simply painting or plastering over the damage is only a temporary solution that doesn't address the core problem. For more extensive or long-term damage, the plaster may be compromised, and there is a risk of mold. In these cases, it is recommended to remove the damaged section of plasterboard and replace it. You may consider hiring a professional for the repair, and it's worth noting that water damage is often covered by home insurance.

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

How you hang the drywall can affect the finishing process. It's often easier to finish horizontal drywall panels, as the seams run across the wall rather than up and down. Standard drywall panels are 48 inches wide, so the seam is easy to reach without bending down or stretching your arms.
