INTRODUCTION

Environmental StoneWorks takes pride in being the leader in our industry. As a founding member of the

Masonry Veneer Manufacturers Association (MVMA), we have helped to develop the highest standards for

the installation of manufactured stone veneer, as seen here in our installation guide.

WORKMANSHIP

This installation guide assumes that construction personnel have knowledge of the materials described

and their proper methods of installation. Prior to commencing activity related to the scope of this guide,

review all adjacent products and other subcontractor’s work that precedes the installation of manufactured

stone veneer to ensure that proper workmanship is reected and that there are no recognizable errors or

deciencies.

BUILDING CODE REQUIREMENTS

This installation guide is intended for use with Environmental StoneWorks manufactured stone veneer

and accessories. Environmental StoneWorks installation instructions follow the requirements set forth

in ASTM C 1780. Building code requirements vary from area to area. Check with local authorities for

MATERIAL REQUIREMENTS MANUFACTURED STONE VENEER 1. Environmental StoneWorks stone veneer is engineered from Portland cement, light weight aggregates, mineral oxide and chemical additives. The product is engineered to achieve a specified strength, color, texture and resistance to effects of weathering. 2. Environmental StoneWorks manufactured stone veneer is engineered in various shapes and patterns to simulate natural stone and is installed in a non-load bearing veneer and trim capacity (e.g.

MATERIAL REQUIREMENTS WATER RESISTIVE BARRIER (WRB) Minimum two separate layers of any of the following: No. 15 felt complying with ASTM D 226 for Type 1 felt, or Grade D paper (ICC-ES AC38), or house wrap (ICC-ES AC 38), or any combination two separate layers of these materials. One layer paper-backed lath meeting requirements for Grade D paper may be substituted for the outer layer. Install WRB in a shingle fashion, starting from the bottom of the wall.
PAGE 5
MATERIAL REQUIREMENTS FASTENERS Corrosion resistant fasteners (staples, screws or nails) must be used to secure flashing and lath. For wood framing, corrosion resistant staples, nails or screws/washers may be used and must penetrate a minimum of ¾” into framing members. For metal framing or panels, corrosion resistant, self-tapping screws may be used and must penetrate ⅜” through metal stud or panel with heads or washers large enough to not prevent pulling through lath.

SURFACE PREPARATION WALLS AND WALL SYSTEMS Verify structural and surface integrity of existing wall prior to installation. Manufactured stone veneer units must only be applied to structurally sound walls. Masonry walls, poured-in-place concrete walls and concrete tilt up panels Must be free of dirt, waterproofing, paint, form oil or any other substance that could inhibit the mortar bond. These surfaces must have a rough texture to ensure a mortar bond.
PAGE 7
CLEARANCES • On exterior stud walls, weep screeds and other base flashings should be held a minimum of 4” above grade or a minimum of 2” above paved surfaces such as driveways, patios, etc. This minimum can be reduced to ½” if the paved surface is a walking surface supported by the same foundation supporting the wall.

INSTALLATION OF MANUFACTURED STONE VENEER Prior to commencing installation of manufactured stone veneer, ensure that the WRB and flashing are properly installed and integrated with each other. Before installing the manufactured stone veneer, it is recommended that a minimum of 25 sq. ft. is laid out at the jobsite so there are a variety of sizes, shapes and colors from which to choose.

INSTALLATION OF MANUFACTURED STONE VENEER PANEL PRODUCTS Environmental StoneWorks panel products are intended to replicate the characteristics of natural materials. It is not intended to have perfectly flush edges as do some alternative products. Uneven planes or deviation in the substrate and framing will likely impact the end product or aesthetic value.

INSTALLATION OF MANUFACTURED STONE VENEER JOINTLESS OR DRYSTACK The back of each manufactured stone veneer should be entirely buttered with mortar to a nominal thickness of ½”. Cover the entire back of the manufactured stone veneer, not just the perimeter. Buttered manufactured stone veneer should be firmly worked onto the scratch coat and slid slightly back and forth to set the manufactured stone veneer.

MAINTENANCE AND CARE SCUFFING Surface scuffing is a normal occurrence on all natural and manufactured stone and is caused by processing, transportation and handling. This is a natural attribute that can add to the aesthetic appeal of the stone. Light scuffing may be removed by following the cleaning procedures outlined in this document. CLEANING Dirt and other particles can be removed from manufactured stone veneer surfaces by using a non-metal bristle brush with water.
