Basic Uses
  • Installation of porcelain, ceramic, mosaic, quarry and paver tile.
  • Installation of natural stone, marble, granite, slate and precast terrazzo tile.
Recommended Surfaces
  • Vertical or horizontal surfaces of concrete, masonry, terrazzo, cement backer boards.
  • Installation over cement mortars and leveling compounds.
  • Existing surfaces of properly prepared tile, stone or cementitious terrazzo.
  • Exterior grade plywood or gypsum board, in interior dry areas only.
  • Flextile waterproofi ng, crack-isolation and sound reduction membranes.
Limitations
  • Installations over nonporous surfaces may require extended setting/curing times.
  • Do not use over particleboard, Masonite, chipboard, OSB or similar unstable materials.
  • Do not use over cushioned resilient fl ooring, rubber, plastic, paint, asphalt, or plywood surfaces in wet areas.
  • Do not use over single layer plywood fl oors. Use only on surfaces, which are maintained at a temperature above 10°C (50°F) and below 35°C (95°F) during application and for at least 72 hours after application.
  • Not recommended for water immersion.
  • Protect from excessive moisture until thoroughly dried and protect from freezing for at least 14 days after installation.
  • To  use directly over gypsum-based patching or leveling substrates, applysuitable primer before use.
  • Do not use for moisture-sensitive stone such as green marble, certain limestone and granite, agglomerate tiles, cultured marble or resin-backed tiles. Instead, use Flexepoxy 100 mortar.
  • For installations subject to severe freeze/thaw conditions use Flextile two component systems.
Installation

Preparatory Work: Surfaces must be sound, even, dry and free of grease, oil, dirt, paint, curing compounds or sealers, or other foreign matter. Surfaces must be true to a tolerance of 3 mm (1/8") in 2.4 meters (8 ft.) for walls and 6 mm (1/4") in 3 meters (10 ft.) for fl oors. Concrete surfaces should have a wood fl oat or steel trowel with broom fi nish. Roughen smooth concrete surfaces. Plywood fl oors should be designed for maximum defl ection of L/360. This normally requires overlay of 16 mm (5/8") exterior grade plywood over 25 mm (1") nominal boards or 16 mm (5/8") plywood when on joists 40 cm (16") O.C. Fasten overlay with screws or screw type nails and glue where possible. Leave a 3 mm - 6 mm (1/ 1/4") gap between sheets of overlay and next to all vertical surfaces to allow for expansion. Refer to current editions of TTMAC 09 30 00 Tile Installation Manual, or TCNA Handbook For Ceramic Tile Installation for information regarding placement of expansion or control joints, or for further substrate acceptability information.

Application: Mix with approximately 5 liters (1.3 US gallons) of water per 22.7 kg (50 lb) bag. Avoid using high-speed mixers. Allow mixed mortar to slake for at least 10 minutes, then re-mix without adding further water. Spread a thin layer of mixed mortar with fl at side of trowel to wet out the substrate; then reapply suffi cient material with a suitable notched trowel that will leave enough mortar to give at least 90% coverage to the backs of tile. Back buttering of tile is recommended for porcelain tile, large format or high lugged tile, ungauged slate, stone, etc. Comb that area which can be covered with tile before skinning occurs. Mortar should be troweled with notches running in straight lines so as to achieve maximum coverage. Press or beat in tile to achieve a fi nished thickness of mortar of at least 3mm (1/8"). Do not adjust tiles after they have been set for more than 25 minutes.

 

Curing and Grouting

Protect from all traffic and delay grouting until cured at least 24 hours, and preferably 48 hours. On exterior or cold weather applications, or when a larger format or impervious tile is installed over an impervious membrane, extended curing is recommended to ensure that mortar is sufficiently cured prior to grouting. Do not allow heavy traffic for at least 5 days following installation, and do not allow heavy construction equipment such as scissor lifts, etc. for a minimum of 14 days following installation. Protection of installation with 13 mm (1/2”) plywood sheets prior to allowing heavy construction equipment is recommended until installation is fully cured. Grout using Flextile Polymer Modifi ed Grout, Flextile 1600UPG Ultra Performance Grout or Flextile FlexEpoxy100 - 100% Solids Epoxy Grout.
