Installation

Surface Preparation

  • Temperature and Surface Requirements:
  • Ensure surfaces are between 40°F (4°C) and 104°F (40°C).
  • Surfaces must be structurally sound, clean, and free of dirt, oil, grease, loose peeling paint, laitance, concrete sealers, or curing compounds.
  • Surfaces should be true to plumb, with slabs accurate to within ¼" (6mm) in 10 ft (3m).

Surface Smoothing:

  • Rough or uneven concrete surfaces should be smoothed with Screed/Plaster material to achieve a wood float (or better) finish.

Dampening Requirements:

  • Dry, dusty concrete slabs or masonry should be dampened, and excess water must be swept off.
  • Installation may proceed on a damp surface.

New Concrete Slabs:

  • New concrete slabs should be damp-cured and must be 28 days old before application.
  • No minimum cure time is required for concrete slabs when thin-set mortar is mixed with a latex additive.

Expansion Joints:

  • Expansion joints must be included in the tile work at all construction or expansion joints in the substrate.
  • Do not cover expansion joints with thin set mortar.
  • For tile or stone installations on plywood and wood substrates, Gresbond EA-100 is recommended.
  • Refer to the specific product Technical Data Sheet for detailed recommendations.

For all stones with a back-protection mesh:

  • It is essential to remove the mesh first.
  • Also, remove the epoxy layer by light grinding to ensure a perfect bond with the adhesive.

Mixing:

  • Place clean, potable water into a clean mixing bowl.
  • Add Gresbond EX-5 powder into the mixing bowl.
  • Use approximately 5 - 5.6 liters of water for 20 kg of powder.
  • Mix with a slow-speed mixer to a smooth, trowelable consistency.
  • Allow adhesive to slake for 5 minutes.
  • Adjust consistency if necessary.
  • Remix and apply with the proper sized notched trowel.

Application:

Tile/Stone Application

  • Apply adhesive to the substrate with the flat side of the trowel, pressing firmly to work into the surface.
  • Comb on additional adhesive with the notched side of the trowel.
  • Use the proper sized notched trowel to ensure full bedding of the tile.
  • Spread adhesive in an area that can be covered with tile within 10 minutes.
  • Back butter large format tiles (> 12" x 12") to provide full bedding and firm support.
  • Place tiles into the wet, sticky adhesive and beat in using a beating block and rubber mallet to embed the tile and adjust the level.
  • Periodically check adhesive for complete coverage by removing a tile and inspecting bedding adhesive transfer onto the back of the tile.
  • Use spacers to provide grout joints between tiles. Joint width shall be as per the recommendation of the architect/engineer.
  • Remove the spacers when the adhesive is firmly set.
  • If the adhesive skins over (not sticky), remove and replace with fresh adhesive.

Note to the Specifier and Installer:

  • Install tile/stone on external walls and floors with joints by creating spaces between tiles/stones.
  • Fill joints with Gresbond Unsanded grout mixed with Gresbond KGA-01 grout admix.
  • Absence of spacer joints can lead to surface movements pushing tiles/stones away from the substrate, causing de-bonding.
  • Ensure exterior tile/stone installations have joints (spaces) on the periphery.
  • Prevent tile/stone from being bound by the peripheral masonry work or plaster.

Tile & Stone installations on ceilings:

  • Check the pull-off strength of the substrate.
  • Be aware that cement-based substrates generally have weak cohesive strength.
  • Understand that unless these substrates are fortified by admixtures or polymer treatment, they may not be suitable for installation.
  • This check is essential for all overhead installations.

Grouting:

  • Grout installation should commence after a minimum of 24 hours of curing time at 70°F (21°C).
  • Use Gresbond Unsanded Grout mixed with Gresbond Grout Admix- KGA-01.
  • For maximum stain resistance of internal spacer joints applications, use Gresbond KE-100 Stainfree Grout.
