Frequently Asked Questions
How long does drywall last?
What is the Standard Lifespan of Drywall? Overall, drywall typically lasts between 40 and 70 years, although it may only last between 20 and 30 years if it is exposed to water buildup as well as mold or mildew.
What goes on a wall after drywall?
Paper tape bonds drywall edges together to form a smooth surface once finishing is complete. Installing paper tape requires putting down a layer of compound over a seam, embedding the tape into the compound, and finishing by adding compound coats over the seam.
When should drywall be replaced?
There’s no universal rule, but it’s usually best to replace any section with a hole larger than five inches. You may also need to consider drywall replacement if your drywall is riddled with multiple smaller holes.
What happens when water hits drywall?
While drywall is made of some pretty sturdy stuff, it can sustain damage when exposed to water for too long. If moisture damage isn’t addressed swiftly, the structural integrity of the drywall becomes compromised, causing it to become soft, weak and susceptible to mold growth.
What happens if you paint directly on drywall?
Applying paint directly to unprimed drywall will result in an uneven finish and require a lot more coats to achieve adequate coverage. Save yourself the wasted time and paint by always applying a separate, high-quality primer to brand new drywall.
Is drywall better than plywood?
Aside from being less fire resistant, more expensive and harder to work with, plywood is the more durable of the two materials. Unfortunately, when plywood is damaged it is harder to fix than drywall. Drywall is more universally used, and it is much easier to find someone to handle your drywall needs.
Is drywall waterproof?
Drywall will never be as waterproof as cement board or polystyrene foam board. Even water-resistant drywall, which is typically green in color, is not waterproof. If you use drywall for your shower walls, you risk mold, rot, and crumbling walls.
Can you paint over drywall?

To prime your drywall, you need to clean it first by sanding it, vacuuming it, and rubbing it down with a black cloth to ensure that all dust is gone.
What is drywall vs sheetrock?
