Mortar (masonry cement and sand mix) should be the best quality available and is available in 40 and 80 lb bags at home improvement stores. For larger projects it is more economical to mix Mortar cement, type S, with masonry sand (1 part cement to 2-3 parts of sand depending on how fine the sand is.

Epoxy or construction adhesive like that used for concrete blocks can be used to set small rock pieces, eliminating mortar mess. RicoRock® Waterproofing also works as a thin set, eliminating the mortar joint.

Additional Materials: All RicoRock® waterfalls have internal plumbing supplied in 2 inch pvc; adaptors, fittings and flex pipe along with pvc glue are needed to complete the connection.

Blue flex hose makes a good sleeve for future lighting.

Tools usually needed: cement mixer or drill with mixing blade, 4 inch Grinder (to cut castings), 24 inch or torpedo level, wheelbarrow, buckets, rubber gloves, trowels, sponges and 2 inch paint brushes (the cheap ones are best), waterhose. A tree dolly works great for moving heavy cast pieces and a rubber mallet is good for pounding the pieces into the mortar without damaging the rock.

The Touch Up Kit that comes with most kits includes a small amount of patch cement (actually Waterproofing powder) that can be used to repair any damaged edges or scrapes. The 4 ounce stains in all 4 colors can be used to add accents or color mortar joints.
