1.  Preparation
All walls must be clean and dust free from dirt, oil, vegetation, and crumbling or loose materials.

2.  Installation of Greenboard using Power’s Foam Adhesive System

i. When installing via the Foam adhesive system, apply a large “dob” of foam adhesive to the middle of each and every masonry block.
ii. Position the board and drill 8mm hole through the masonry at each corner offset in by approx 100mm.
iii. Hammer the Hilti IDP anchors in.
iv. Use a minimum of 8 IDP anchors for each 2500 x 1200 board with at least 2 x IDP anchors staggered in the mid section of the board.

3.  Final Checking of Greenboard installation on Concrete and Masonry Walls – Before rendering, any irregularities in the surface of the sheet or joints are sanded back using a coarse rasp.

4.  Expansion Joints within The Greenboard installation on Concrete and Masonry Walls – All expansion joints in the substrate must be carried through the complete cladding system.
