Pewter Installation Instructions


We provide these pewter tile installation instructions as a general guideline only.

Notes for Specifiers and Installers:
A high percentage of our product is tin. Tin has been recognized since 7700 BC but wasn’t commonly as a material of choice for casting fine pewter details until the eighteenth Century. The process of metallurgy is one of the oldest sciences. Artists throughout the world have employed casting metal techniques to bring a rich heritage of intricate designs and style.
Upon receiving the Pewter Accents, we recommend that the customer open and inspect each carton, under adequate lighting.  Any irregularities between the intended purchase order and the material delivered must be communicated immediately to the point of purchase. No adjustments will be made after the tile has been installed.
We recommend the selection of a referenced and reputable tile contractor, experienced in the setting of pewter tiles. The tile installer must review and understand our installation recommendations before initiating the application.
We recommend that setting materials be selected from industry recognized leaders and that installation methods and material handling directions be followed.  Do not substitute with other brands of latex admixes or dilute with water; the results may vary considerably from those desired and acceptable.
Are essential for most tile installations. Expansion joints will vary, depending on the substrate, climate, and size of the installation. Expansion joint and construction of the joints should follow the TCA or TTMAC recommendations.
All mortar beds should be allowed to cure a minimum of seven days, prior to installing Pewter Accents Tiles.
B. When used on a floor application, allow your bond coat additional time to maximize curing (48 hours), before grouting. Pewter tiles are so completely vitrified, competent adhesion requires extra efforts and polymer-enhanced mortars and grouts, unlike ceramic tiles.
C. All submerged heavy mineralized water installations should have a full 28 day recommended cure, after grouting, before submersion.
D. The performance of a properly installed thin-set (thin-bed) application is dependent on the suitability of the substrate. (flat, clean, rigid, sound)
E. Cutting - For the best results, we recommend that installers use quality wet diamond blade saws with a continuous rim diamond blade for maximum performance.  A simple hack saw is also a practical method of cutting pewter tiles, followed by smoothing of edges with an emery-board or with a grinding or sharpening stone.
F. Drilling - A sharp carbide or diamond chipped drill bit can be used to drill pewter successfully.
G. Safety - When handling and cutting pewter, always wear protective goggles and gloves.  When mixing setting materials or handling power equipment, follow the manufacturer’s materials safety and handling recommendations.
H. Surface Resistance - When added into floors for decoration, pewter tiles may not be adequate under higher traffic conditions. We don't recommend using pewter with surface patinas, oxidized or plated tiles, in areas where they would need regular abrasive cleaning, such as inside a bath or shower area. It’s important to assess the area in which the pewter has been selected and determine if acceptable.
I. Use sanded grouts for all Pewter Accents.  Non sanded grout joints have a recommended maximum thickness is 1/8 and for sanded they begin at 1/8 thickness. We recommend polymer-modified sanded grout or even modified epoxy grout. Follow manufacturer’s recommendations for preparation and use. The sand within the grout should be carefully applied, not to scratch the surface. The cementitious sanded grout should not be mixed too dry, making it necessary to aggressively pack gritty grout into the joints. Also, it cannot be too wet so that it will run. Mix it to a consistency of butter so that it can be shaped and easily fill the joints without force. The acrylic or latex materials in polymer-modified grouts help to encapsulate the sand making it less gritty. We recommend adding a latex admix to standard sanded grout, use an already polymer-modified dry mix grout powder, or use a modified epoxy grout – for a full, flush grout joint.
J. Trowels for applying pewter tiles to wall surfaces, use a 3/16” x 1/4 V-notch trowel with a polymer-modified non-sagging wall thin-set.  The backs of tiles require back-buttering to fill in the locking void.  For applying floor pieces, standard polymer-modified thin-set is recommended with a trowel appropriate to the tile application, commonly º” square notch for 12”x12” (nominal 30x30cm) 13”x13” (nominal 33x33cm)  and 16”x16” (nominal 40x40cm) Ω” (  elliptical or half moon trowel.

Pewter Maintenance

All pewter will tarnish slightly over time, which will generally add to its beauty and allure. In general, a light dusting is all that is required to keep the material looking good.

Polishing Recommendations
If you feel that you need to restore more zest or brightness to your pewter, we recommend using a Scotch Brite pad. This pad is not as abrasive as a Brillo pad so is less likely to harm the soft metal pewter. The Scotch Brite pad should be used DRY.

Gently rub a small area in a circular motion until the desired result is achieved. The pad will make contact with the higher surface of the tile and leave the valleys (recessed areas) darker. Rub gently and examine as you go along; the more pressure, the brighter the pewter will appear. Do not over-rub to avoid damaging the surface. You do not have to use solvents, cleaners or other aftermarket products. Should you use a commercial cleaning product, please make sure it is specifically intended for use on pewter.

Cleaning Recommendations
If for some reason an acidic liquid, like soda, comes into contact with the pewter, immediately blot the surface of the tile with warm water and a cloth or sponge to in order to neutralize and remove any liquid. Dry with a cotton cloth.

If the pewter comes in contact with an alkaline liquid, such as a detergent, immediately apply a generous amount of water to the pewter tile to wash the liquid away. The negative effect of alkaline is that it will make recessed areas turn white in color as opposed to the traditional oxidized look. Dry with a cotton cloth.

Acidic or alkaline contact may not show adverse effects for a couple of days; therefore cleaning as soon as possible will eliminate possible damage.

Finally, several days after using the above cleaning methods, you may wish to give the surface a quick Scotch Brite rub to bring back any lost luster or brightness if needed.
