Sealed containers are guaranteed to be more than 18 months if stored at between 5℃ to 40℃.
Preparations:
Store resins at room temperature >21°C for 24 hours before using. All surfaces must be sound, clean, free of oil, waxes, frost, curing agents, form release agents or other bond inhibiting contaminants. All substrates must be clean and dry when application of 211 Stone Adhesive is made. Expansion joints shall be provided through the tile work from all construction or expansion joints in the substrate. Do not cover expansion joints with mortar. Finish veneers equipped with any type of resin, mesh,
epoxy or fiberglass backing must be ground down to bare stone in those areas to receive 211 Stone Adhesive. Clean and grind back of stone at areas to receive the 211 Stone Adhesive spots using mechanical wheel grinder with diamond wheel/blade. Remove dust with stiff brush and wipe entire surface. Using damp sponge (not wet), wipe the tile or stone to remove any particles or remaining dust to ensure a clean direct bond and that all ground material is removed. Wipe dry with a clean cloth, then apply 211 Stone Adhesive.
Mixing:
Combine equal volumes of 211 Stone Adhesive Part A and Part B (1:1 mix ratio by volume). Mix until uniform in colour; no swirls. Small quantities can be mixed with a putty knife or margin trowel. Larger quantities can be mixed with an electric drill mixer (low speed).
Application:
Apply dabs evenly distributed on back of the stone or tile; 5 dabs minimum, 1 each corner and 1 in centre. Cover at least 10% of the area of each piece. Finished dab thickness must be a minimum of 3 mm, maximum 25 mm.
Approx. dab diameter required to achieve 10% coverage with 5 dabs
Stone or Tile size Dab Diameter
300mm x 300mm 50 mm
600mm x 600mm 100 mm
900mm x 900mm 150 mm
Joint Treatment
Exterior Application:
YY-315H2 water borne epoxy grout or YY-312 cement based grout are recommended
Interior Application:
YY-315H1/315H2 epoxy grout or YY-315 cement based grout are recommended.
Test area to ensure proper filling as narrow veneers and wide gaps behind the veneer may not allow for joint filling with an epoxy or cement grout.
Note: Control, expansion or other movement of joints must be treated with a flexible sealant.
Cleaning
Clean tools and work while epoxy is fresh, using warm water. Detergent or soap can
be added to the water for easier cleaning.
