If splashed in the eyes, flush repeatedly with warm water for at least fifteen (15) minutes and call a physician immediately.

PLEASE NOTE:

Recommended thickness for the river rock surface is : 1/2 inch thick for pools, decks, patios, and walkways. For driveways, the river rock should be 3/4 inch thick.

IMPORTANT:

If the temperature is below 60F, COLD WEATHER RESIN MUST BE USED

BASIC INSTALLATION:

I. Tools

A. Cement Mixer (3 cu.ft. capacity)

B. Wheelbarrow (s)

C. Iron-tooth rake to spread rock to approximate thickness

D. Trowel (for finishing of product)

E. Propane Torch (to remove any moisture)

F. Hammers

G. Chipping Gun (plane down concrete at thresholds)

H. Tapcon Drill and Tool

II. Forming Materials

A. Forming Stakes

B. 1” x ___ (wood forms) for over pours and steps.

C. Cantilever forms (pool edges).

D. Form Release (to keep product from sticking to forms)

E. Tapcon Screws.

III. PREPARATION FOR DECK

A. Must be clean and dry

B. Follow existing expansion joints accordingly

C. Remove spoiled or flaking concrete

D. Build up or channel low lying areas for necessary drainage

E. Asphalt or wood surfaces must have coat of epoxy applied prior to installation of

river rock

IV. FORMING

A. Wrap product around edges of deck that can be seen.

B. Apply light coat of epoxy to vertical edge of substrate.

FORMING PROCEDURES:

Place forming stakes against edge of vertical substrate; this will space out from existing edge allowing product to fill in void between existing edge and form. Place pre-waxed form against stakes and install forming stakes to hold form in place.

FOR STEPS:

Follow above procedure except fasten form with tapcon or concrete nails. While installing river rock, remove spacing stakes as the river rock fills voids. Trowel top to smooth finish and level edge.

FORMING OF CANTILEVER EDGE:

Place a row of duct tape on pool tile. Top edge of tape should follow top edge of pool tile. Apply double face tape to foam then extender to the opposite side of the tape. Apply form adhesive to foam backing and glue backing to extender. Install concrete nails in concrete approximately one foot from edge of pool and space nails about every two feet around pool. If pool has straight edges use strips of 1x2 wood. If pool has curved edges, use strips of 2” masonite. Drill holes through wood backing. Place above mentioned backing strips against foam backing, pull tight and tie wire to nail. After river rock is installed and hard, remove forms and cut tie wires even with rock edges. River rock dace needs to be ground slightly to smooth edge. After grinding anddust has been removed, apply light coat of epoxy to surface that has been ground.

V. MIXING OF MATERIAL

A. Epoxy has a set mix ratio (do not vary). Mix three (3) equal parts resin to one (1)

equal part of cure. Mix vigorously for at least two (2) minutes.

B. Place correct poundage of desired pebble in cement mixer and add mixed epoxy.

C. Let epoxy and stone mix until all stones have been covered with epoxy.

VI. FINISHING THE PRODUCT

A. Place river rock at place of installation

B. Spread evenly with rake

C. Trowel to a smooth finish. In order to obtain a smooth finish, trowel must be

occasionally cleaned with a proper solvent (Xylene, Trowel Slick, etc)

FINISHED PRODUCT SHOULD NOT BE WALKED ON UNTIL THE NEXT DAY!!!

CAUTION: Product should not be installed when temperature will not rise above 60°F. On such days, cold weather resin should be used.

What is Pebble Bond Epoxy?

Pebble Bond Epoxy is a high-performance epoxy binder used with River Rock Pebbles create a seamless, decorative flooring system. It combines epoxy resin with pebbles or marble to form a durable, slip-resistant surface for residential and commercial spaces.

What is River Rock epoxy flooring?

River rock epoxy flooring (also called epoxy stone) is a system made by mixing Pebble Bond Epoxy with decorative natural stones like our River Rock Pebbles. It is designed to cover and improve concrete surfaces while creating a uniform, attractive finish.
