How to Install Green Board In a Shower

Green board comes in other colors than just green. Yellow or blue are also available colors and offer the same benefits as green board does. Green boards serve as a water resistant surface and not recommended to encounter water, as this will result in damage to the green board. Installing green board is a relatively easy project. Green board is smaller than regular dry wall or gypsum sheets.

 

Things you will need

Drywall screws 1 1/4inch
Tape measure
Razor knife
Power drill
Joint compound
Putty knife
Vapor barrier (plastic)
Stapler
Staples
Water resistant tape
Straight edge
Drywall sanding block

 

Step 1
Apply the plastic vapor barrier to the studs surrounding the shower walls. Start at the bottom of the wall on one corner and staple the width of the plastic to the stud that corner of the wall. Roll the plastic out length wise (across the wall) and staple to every stud while pulling the plastic tight. Cut the plastic from the roll after you have reached the opposite end of the wall. Overlap each row of plastic one-inch on each other and tape the seams of the plastic. Repeat this step until all of the insulation and studs become protected with the vapor barrier plastic.

Step 2
Measure the wall to see where a three-foot wide piece of green board will line up onto the studs. The green board should align centered onto the wall stud, as this will allow the second piece of green board to joint tightly against each other. Measure the green board to the appropriate measurement needed for this application and use a straight edge as a guide for your razor knife. Score the green board using a razor knife; just enough to cut through the paper of the green board. Bend the green board on the cut line until it snaps, then cut the backside of the green boards paper backing to remove the cut piece. Always install the green board so that the factory edges make up every seam or joint on the wall, this gives the green board a better seal.

Step 3
Apply the sheet rock screws vertically every seven-inches apart from each other, and one inch from the edge of the green board to avoid blowouts of the board. Repeat these steps throughout the application process.

Step 4
Apply joint compound to every seam and screw used in the application of the green board. Using a putty knife, apply a thin layer to the seams and screws. Let the first layer of joint compound dry and sand smooth. Apply a second coat of joint compound to all of the seams and screws; let dry and sand smooth again.
