How to Lay Drywall on Top of Eco-Block

Install the subfloor for the room before laying drywall against the walls.

Measure the dimensions of the Eco-Block wall where you’re installing the drywall panels, using a tape measure. Subtract 1/2 an inch from the measurement to leave a 1/4-inch gap at the base and at of the wall for expansion. Measure the drywall panels as well. Use the two measurements to plot out the positioning of the panels on the walls, using as many full-sized panels as possible.

Place the drywall panel against the wall, flush with the surface of the blocks.

Attach the panels using #6 coarse thread screws. Drive the screws every 8 inches through the drywall and into the lines of plastic webbing located in the Eco-Blocks. The webs are located beneath the deeper grooves running vertically through the block surfaces. Use a drill with a screwdriver bit to drive the screws into place, creating a line of them along the webbing spaced 6 inches apart. Stagger the panels at the joints in adjacent rows, with a new row’s joint beginning 16 inches away from the previous row placed.

Cut the panels as needed with a utility knife, either to cover a smaller space or to create the staggered joints. Score the panels with the knife, using a straightedge held against the panels as your guide at the cutting position. Snap the scored panel towards the knife line to break it where needed. Screw the partial panel into place.
