SPECIFICATIONS

 

General Description

McIntyre CLASSIC PORCELAIN, CLASSIC STONEWARE, NORTH COAST STONEWARE AND STREAMLINE tile are formed from wet clay, hand finished and hand glazed and single fired to 2400 degrees F. Each tile has a flat back and cushioned edge. Custom tiles may be produced at other temperatures and with other processes. 
 

Standard Specifications

McIntyre Tile conforms to ANSI 137.1 as Special Purpose Tile. Our tile are produced, graded and packed to our stated specifications. When requested by the purchaser prior to production, a Master Grade Certificate may be issued certifying compliance with properties mutually agreed upon by purchaser and McIntyre Tile. Generally, a Master Grade Certificate should be requested when the tile is specified for a commercial floor or any exterior use. 
 

How to Specify

Glazed, high fired ___________________ (specify Classic Porcelain, Classic Stoneware, North Coast Stoneware or Streamline) tile in actual size ________________ (specify actual size) and color ___________________ (specify glaze name) as manufactured by McIntyre Tile Company, Healdsburg, California. Tile shall have a flat back, a cushioned edge, and shall be fully vitrified (absorption less than 3%). Tile shall conform to ANSI 137.1 as Special Purpose Tile. Allow 6-10 weeks production time at time of purchase order was received to production completion. 

Availability

This tile is made to order and are therefore subject to production limitations and order volume fluctuations. For purposes of specification please check with the factory or your local distributor for verification of delivery. 
 

Color Variation

Most McIntyre glaze colors vary from tile to tile, some more than others. These variations are intentional, resulting from our particular production methods and our choice of raw materials. When specifying a McIntyre glaze, always work from a sampling of 3 or more tiles which represent the range of color you can expect on the job. 
 

Murals

McIntyre murals should be laid out prior to installation to verify the spacing and fit. The tiles surrounding the mural should be carefully chosen to blend with those in the mural itself. Install murals at the same time as surrounding tiles to assure correct fit. 
 

Slip Resistance

If specified when ordered, McIntyre will add an abrasive grit to any glazed tile for use on floors. The grit is either white (pure silica) or black (nickel alloy). The abrasives are most commonly used on shower floors and commercial floor applications. 
 

Crazing

Crazing refers to the hair-line cracks which may occur in the glaze surface of tiles after firing and is common in hand crafted tile. All ceramic glazes are eventually subject to this effect. Certain glazes produced by McIntyre Tile are intentionally crazed for decorative effect. To minimize the possibility for staining, the factory recommends the use of natural gray grout. Penetrating sealers or grout releases may also be used per the manufacturer's instructions. To highlight the crazing, colored stains may be rubbed into the surface before sealing. 
 

Size Variation

Because of the substantial shrinkage from wet to fired in the manufacturing, McIntyre tiles are subject to size variation. Dimensions on 6x6 and smaller tiles may vary up to 1/16" from the actual size specified, on 8x8 tile to 3/32" and on 12x12 tile to 1/8". Tile thickness may vary 1/32" from the dimensions specified. Deflection on 12x12 tiles is limited to 1/8" from a straight edge. 
 

Custom Color Development

We specialize in custom color development. Generally, we can match the hue and sheen of a sample submitted. For a fixed development fee, we will conduct a series of glaze tests and make a prototype tile for submittal. Custom glazed tiles made for a job are surcharged 20%. Typically 2-4 weeks is needed for testing, however, please check with the factory for current development time in our glaze lab. 
 

Installation

Installation procedures should conform to the Tile Council of America "Handbook for Ceramic Tile Installation" (current edition). The layout should be evenly spaced on each surface and maximize the use of full tiles. Grout joints should align. Avoid grouping tiles of the same hue or value. Choose stacks of tiles from several different cartons to achieve the best overall blend of color. 
 

Grout Space

McIntyre is sized modular with a square foot space allowing a 3/16" grout throughout. A narrower grout spacing can be used including "tight", however, additional tiles will be required to cover a given area. Close grout spaces accentuate tile irregularities. 
 

Frost Proof

McIntyre Tile has a water absorption of less than 3% (vitreous) and is suitable for use in pools and spas for both interior and exterior applications. 
 

Colored Grouts vs. Natural Gray

The factory recommends natural gray grout for all of its glazes to minimize staining from colored grout pigments. Caution is especially recommended with matte glazes. Test a loose piece of tile before grouting your installation. To reduce staining, use a Grout Release before grouting (except with Copper Flash glaze). Always test before using. Do not apply any materials to your tile without first satisfying yourself by testing, that the result will be satisfactory. 
 

Maintenance

Minimal maintenance is required. Mild soaps should be sufficient for most cleaning. For persistent stains, stronger cleaners (even mild acids) may be used on the tile (except for Metallic glazes), but care must be taken to avoid contact with the grout, especially if a colored grout has been used. Test any cleaners before general use. 
 

Durability Considerations

Depending on specific site conditions, all glazed tile are subject to wear over time. To determine the suitability for specific applications, each McIntyre glaze has been tested and ranked on the MOHS scale and classified according to hardness and recommended use. Light colors and matte glazes are a better choice in heavy use areas rather than dark colors and gloss finished glazes because scratches on the tile surface are less apparent. A means must be provided for people to clean abrasive materials off their shoes before walking on a glazed tile floor. 
 

High-Fired Metallic Glazes

These tiles feature metal molecules embedded on the glaze surface for a sensational metal effect. The glazes are non-toxic in both manufacture and usage. The glaze surfaces are sensitive to oxidation and must be protected. It is pre-sealed at the factory. Periodically the sealer must be renewed to protect the metallic quality. These glazes are NOT suitable for areas where abrasion, water and/or strong chemicals are present. Pre-test any sealers or grout releases before general use. Some products will discolor the glaze/metal surface. McIntyre Tile will not be responsible for discoloration to this tile from chemicals or moisture.
