Installation:

Mixing

For best results, maintain all tiling materials, substrates, room, and adhesives at 50°-70°F (10-21°C) for 24 hours before and 48 hours after installation. In a clean mixing container, add 50 lbs. (22.68 kg) VISON POLY MUD to 3 to 3 ¹/₄ quarts of clean, cool water. Mix material to a thick consistency.

General Surface Prep

All surfaces must be dry, and structurally sound.  Remove all grease, oil, dirt, curing compounds, sealers, adhesives, or any other contaminant that would prevent a good bond.  Glossy or painted surfaces must be sanded, and stripped of all contaminants. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a coarse finish to enhance the bond. The ambient temperature should be maintained above 50º F (10º C) or below 100º F (38ºC) for 72 hours to achieve a proper bond.

Cementitious Substrates

Concrete or plaster must be fully cured and must accept water penetration. Contaminants should be mechanically removed before installation. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a coarse finish to enhance the bond. Smooth concrete slabs must be mechanically abraded to achieve a proper bond.

Expansion Joints

Install expansion joints around all perimeters or restraining surfaces where possible to allow for expansion movement. Expansion joints and cold joints, as described in ANSI A108.01, should never be bridged with setting material. They must be brought through the tile work and filled with an appropriate elastomeric sealant. Contact Vison Tech’s Technical Services for the proper treatment of control or saw-cut joints. Refer to Handbook EJ171.

Coverage

It will be approximately 50 square feet per 50 lb. bag at ¹/₈” thickness.

Cleaning

Clean tools, hands, and excess materials from the face of the tile, while the mortar is still fresh, with warm soapy water.

Curing and Grouting

Grouting may be accomplished when tiles are held firmly in place, typically 24 hours after installation is completed. No traffic is permitted over the tiles prior to grouting. Cold temperatures or high humidity may extend curing time. Unglazed tiles may require sealing prior to grouting so discolorations will not occur.
