PREPARING THE WALL 
OVER MASONRY SUB-SURFACE 
Step 1 
A smooth, flat, stable surface is required for proper installation of NextStone. Concrete 
walls may need some filling to unless they are in a smooth, flat condition. Uneven walls 
may require furring strips to provide a flat surface. 
Step 2 
When applying NextStone directly to concrete walls the use of concrete screws is 
recommended. Please refer to page 8 for fastener information. NextStone recommends 
testing these products or consulting with the manufacturer before using this or similar 
products.
