Pebble-Flex Manufacturer’s Specifications

1.      General

1.1 Scope: These are the manufacturer’s specifications for the Pebble-Flex resurfacing system.

1.2 Description: Pebble-Flex is a porous thermoplastic aliphatic rubber designed to be used in the resurfacing of: concrete, wood, asphalt, stone, metal, and fiberglass. It will bond to most surfaces and will resist surface movements. It has been designed to be totally light stable and will not deteriorate under harsh weather conditions.

1.3 Work: Provide all necessary materials, labor, tools, and equipment to perform the work included in the section for the installation of the poured-in-place resurface.

1.4 The installation of the new surface shall be completed by Pebble-Flex Certified Contractors or by the Pebble-Flex Installation Division. Manufacturer’s detailed installation procedures shall be submitted to the Architect and made part of the Bid Specifications.

1.5    Temperature must remain above 50F throughout installation and curing processes.

1.6 Site must be secured against vandalism during installation and curing processes.

2. Submittals
   
   2.1 Manufacturer’s Product Literature and Specification Data.
   
   2.3 Submit manufacturer’s written instructions for recommended maintenance practices and a 6” by 6” sample for approval by the engineer or architect.
   
   2.4 Color samples for customer verification.
3. Products
   
   3.1 Product: Pebble-Flex poured-in-place resurfacing system.
   
   3.2 Materials: Pebble-Flex two-component, 2A to 1B, Polyurethane Primer, Pebble- Flex thermoplastic aliphatic rubber pebbles, Pebble-Flex aliphatic, 100% solids, moisture cure, Polyurethane Binder. Each one hundred pounds of Pebble-Flex pebbles is mixed with one gallon of Pebble-Flex Binder.
   
   3.3 Finish Texture: Pebble grain.
   
   3.4 Color: Selected from Manufacturer’s Color Chart by owner prior to bid.
4. Surface Preparation
   
   4.1 New or Existing Concrete: New concrete must be at least 28 days old, and can be prepared simply by acid etching. Add acid slowly to water in clean polyethylene buckets at a ratio of three parts acid to one part water. Care should be taken to prevent splashing on workers. Protective clothes such, as rubber gloves, boots, etc. should be used. If contact with skin occurs, flush the area with water for 15 minutes and consult with a physician if necessary. The acid solution should be used on the floor at a rate of 100 square feet per 5 gallons of acid. Using a stiff broom, scrub acid solution into the surface where the solution was poured and continue the process to other areas. Never let the floor dry with acid on it, after 5 minutes rinse the floor with large amounts of clean water to remove all the acid solutions, then allow the floor to dry. Old concrete that is contaminated with grease or oil can be cleaned with a power washer. If needed use a degreasing agent before power washing. For concrete where a power washer cannot be used, a diamond grinder can be used to lightly grind the surface to remove contamination. New concrete should be allowed to cure for 30 days before treatment.
   
   4.2 Metal Preparation: All metal surfaces must be rigid and structurally sound. Contamination such as grease, oil, dirt, etc. must be removed prior to coating. Rust or scale should be removed through mechanical means such as sanding or sand blasting. The surface should be abraded until bright metal is showing. If the surface is to be left for an extended period of time, it should be treated with a 10% phosphoric acid solution to prevent new rust formation.

      4.3 Wood Preparation: Pebble-Flex should not be applied over plank or strip    flooring. Sheets of one half inch or thicker plywood may be used to cover this type of floor. Exterior grade “C” plugged, with extended glue line should be used.          The plywood sheets should be staggered for strength. Lightly sand the wood      surface to clean off any contaminants or power wash. Allow 24 hours for wood to               dry thoroughly.

      4.4 Stone or Tile Preparation: Any unstable or loose tile must be removed.        Contamination should be removed with a power washer or mechanically abraded.        4.5 Fiberglass Preparation: Power wash any contaminants off the surface. Allow        24 hours for the surface to dry. Solvent wipe the fiberglass surface before coating          with primer.

5. Installation
   
   5.1 Forming: Following the shape of the area to be surfaced, form out the area with 1 x 4 inch wood strips or plywood cut into 4 inch strips. Stabilize the wood with spikes or stakes and thoroughly wax the wood surfaces with carnauba wax.
   
   5.2 Priming: Roll or brush Pebble-Flex two-component, one to one, Polyurethane Primer onto the surface being sure to liberally cover the entire area. Mix an amount of primer that will be used in less than 15 minutes. Normally this would be approximately one gallon at a temperature of 85 degrees F. If it is warmer, the primer will cure faster and less material should be mixed. Only prime 700 square feet at a time, and as the installers approach an unprimed area, prime 700 additional square feet.
   
   5.3 Pebble-Flex Mixing and Finishing: Mix two bags, 100 pounds, of Pebble-Flex pebbles with one gallon of Pebble-Flex aliphatic, moisture cure, Polyurethane Binder in a wheelbarrow or mixer. Mix thoroughly so that each pebble is covered evenly. Dump the mix onto the primed area and spread it with a rake then trowel to an average thickness of 0.375 inches, keeping the surface as level as possible. Hand or power trowel using a solution of soapy water to spray the surface of the trowel. This will allow easier manipulation of the trowel as well as aid in the curing of the Polyurethane. Let the surface set for 24 to 72 hours or until dry to the touch before using.
6. Cleaning and Demonstration
   
   6.1 The contractor should clean the jobsite of excess materials and if necessary backfill any excavation around the perimeter with earth or other appropriate material.
   
   6.2 The contractor shall instruct the owner’s personnel on proper maintenance and repair of the Pebble-Flex surface.
