Drywall Insulation questions, answered by experts

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.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.

You can put drywall mud over paint to even out the surface or entirely resurface it. Sand the surface with 280-grit sandpaper, vacuum the debris and dust with a shop vac, and clean it with a slightly damp cloth. Allow the surface to dry. Apply drywall primer, especially if you’re skim-coating an entire wall. Apply the right type of drywall mud over the surface and smooth it with a trowel. Allow the layer to cure fully, then sand it before applying another layer or painting it.

A utility knife is sharp enough to score the drywall and it may work in a pinch for outlet box holes. However, one of the best tools for drywall when you need to make exact cuts for an outlet box quickly is a drywall saw. This handheld tool has a longer blade than a utility knife, so it penetrates the thickness of the drywall easily. The design of its handle and the teeth in its blade make it easier to control while cutting quicker than you can with a utility knife.
