PART 1: GENERAL

Submittal

Submit color sample(s) of each color specified from manufacturer's series. Submit product literature, certification, test reports, full size sample(s) of each color specified or selected.

Quality Assurance

All high density prefinished concrete masonry units shall be ULTRA® BURNISHED masonry units manufactured by PREMIER BLOCK CORPORATION. All units shall conform to ASTM C90-00 moisture controlled and shall have a groundface finish as shown on the drawings. Field Constructed Mock-ups: Construct a sample panel, no less than 4x4, of units of each color and size to be used in the project. The cleaning agent and method should also be determined at the time sample panel is constructed. All units contain Premier Block-approved integral water-repellent CMU admixture at the time of manufacturing.

Delivery, Storage and Handling

ULTRA® BURNISHED units shall be delivered to the jobsite on banded wood pallets. Each exposed face shall be protected by a plastic protective layer. Each edge of a cube shall be protected by a pre-molded edge protector. Each cube shall be covered with a clear plastic wrap. Pallets shall be stored in singlestacks on level ground and covered with waterproof covering (e.g. tarpaulins) to protect the units from inclement weather. Units must be handled carefully to avoid breakage and damage to the finished surfaces.

PART 3: EXECUTION LAYING MASONRY WALLS

Lay units using the best concrete masonry practices. Install only quality units; reject all defective units. Align units level, plumb, and true with uniform, carefully-tooled 3/8" wide joints on the finished side of the wall. Draw blocks from two or more pallets at a time during installation.

Installation

Lighting: Provide adequate lighting for masonry work by placing all lighting a reasonable distance from the wall for even illumination. Do not use through lighting.

Cutting: Make all unit cuts, including those for bonding, holes, boxes, etc., with motor-driven masonry saws, using either an abrasive or diamond blade. Cut neatly for best appearance.

Inspection

The facing shall be free from chips, cracks, crazes or any other imperfections that would detract from the overall appearance of the finished wall when viewed from a distance of fifteen (15) feet at right angles to the wall with normal lighting.

Flashing of Masonry Work

Install flashing at locations shown in the plans and in strict accordance with the details and the best masonry flashing practices.

Weep Holes and Vents

Install weep holes and vents at proper intervals (32" O.C. and 2" long, above bed joints, typical) at courses above grade, above flashing, and at any water stops over windows, doors, and beams.

Cleaning

Keep walls clean daily during installation using brushes, rags, and burlap squares. Do not allow excess mortar lumps or smears to harden on the finished surfaces. Remove green mortar with burlap or a dry cloth. Harsh cleaning methods after walls have been erected might mar the surface of the units.

Final Cleandown

No ACID or ACID-base solutions shall be used in the cleaning of ULTRA® BURNISHED units. A detergent masonry cleaner shall be used following the manufacturer's instructions and the surface shall be thoroughly rinsed with clean water.

Field Coat Application

A field coat of proprietary acrylic sealer must be applied to all ULTRA® BURNISHED Block to maintain the limited warranty. For a finished wall, apply a jobsite application of proprietary acrylic (minimum 20% solids content) to all ULTRA® walls after cleandown and when the walls are dry. Apply the acrylic evenly to cover the entire surface without forming drops or runs. For maximum coverage and best appearance, apply acrylic with airless spray equipment. This clear, high-solids acrylic offers excellent graffiti resistance, provides moisture resistance and helps to cover any scuffs or scratches that may occur during handling and/or installation.

Maintenance

ULTRA® BURNISHED units, properly installed and cleaned, need virtually no maintenance other than routine cleaning with standard commercial grade cleaning agents. Graffiti, paint or dye stains might need special cleaning methods and products. Contact manufacturer for specific cleaning recommendations.
