INSTALLATION

SURFACE PREPARATION

Surface should be level and rough to ensure better adhesion of EZ Rocks. For new construction, have the wall steel-trowelled or raked. Finished or painted masonry walls must be roughened either through chipping or cutting vertical and horizontal lines on it. Use a hand-held circular saw with masonry blade to do this. A metal or wire lath with scratch coat is needed for walls such as wood or fiber cement board.

MORTAR MIXTURE

Dry mix 1:2 portland cement and heavy-duty tile adhesive and add water slowly until a paste-like consistency is achieved. For high-rise installation, 1 part Portland cement and 3 parts heavy-duty tile adhesive may be used.

APPLYING EZ ROCK

Cover the entire back of EZ ROCKS with about ½ inch of mortar and press it firmly into the wall, making sure to squeeze out some mortar around it edges.

Corner stones should be installed first, starting from the top down. Alternate the long and short legs of the corner stones in opposite directions. Apply flat stones starting from the outside and working towards the center of the wall. Make sure to alternate small and long pieces only when necessary (use broken pieces for this purpose). Always put level or chalk lines on the wall surface to serve as guide in installing the stones.

GROUTING JOINTS

For some EZ Rocks profiles that are best installed with joints, prepare a colored grout mix that compliments your stone color. Using a grout bag, squeeze the grout mixture to fill the joints between stones. Dry the grout until firm but not solid then use a jointing tool or stick to compress and set the grout into place around the stones. Brush off excess grout or mortar with a whisk broom or soft-bristled brush and clean the stones.

SEALER APPLICATION

If desired, a matte-finish breathable penetrating masonry sealer may be used as topcoat for EZ Rocks. Make sure to test the sealer first on a single stone to see the result and follow manufacturer’s instructions. For the best results, we highly recommend EZ Rocks sealer for this purpose.
