First, you have to cut the pieces to certain size with a metal straightedge and a sharp utility knife. Using a sharp utility knife, locked the straightedge in pace then score it through the outer paper coating. You can break the drywall out changing from its overall size once the drywall is scored.

2. Install drywall on walls

You can install water resistant drywall just like installing standard drywall. First, drive the screw into the drywall and the stud behind it. Make sure you drive it just below the surface and you have to avoid going through the drywall entirely. The gypsum core on drywall can’t hold fasteners well and it isn’t strong to rely when you install it. When you decided to go with multiple rows of drywall on your wall then sway the material away to keep layers from lining up. Staggered joints are more reliable and stronger than layers because you will find difficulties in cover it up when it comes time to mud and tape it.

3. Put the drywall on ceilings

Since it is heavier and also a bit weaker than standard drywall, you have to be careful in order to avoid sagging issues during installation. Instead of 16 inches, it’s very important to fasten the drywall every 12 inches to give the best solution in putting the drywall on ceilings.

You should strap your ceiling first to do this. Purchase a 1’x3’’ lumber is a must, and then use it to fasten perpendicular to the joists in the ceilings. When you do this, the installations will more secure and simpler and it’s also a good practice when you want to secure your drywall on ceilings.

4. Finishing the installation

After you the drywall all locked in place properly, then the time to finish the drywall installation comes. Tape and mud it entirely and don’t forget to apply a layer of protective paint. Paint every layers and all of the screw holes with mud (also called joint compound) with a putty knife. And use the knife again to press drywall tape into each of the layers between the panels. With another layer of the compound, go back over then to cover and makes sure that they are really stick in place properly. Leave it until the coating is dry and you can apply one or two more coatings.

You can begin painting the drywall when the mud covering the walls and ceilings properly. Just like painting a common wall, wipe away the dust from drywall with a damp cloth and then paint it using a durable paint which designed for damp area. The installation is completed.
