Instructions
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 PUA-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 - 5.5 litre 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.
Contact Gresbond technical services for large format tile or stone installations on exterior surfaces.
Application
APPLICATION : TILE/STONE
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.
-
Use the proper sized notched trowel to ensure full bedding of the tile.
-
Spread as much adhesive as can be covered with tile in 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 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.
-
The joint width shall be as per the recommendation of the architect/engineer.
-
Remove the spacers when the adhesive is set firm.
-
If the adhesive is skinned 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 admixture.
-
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
Before installing tiles or stones on concrete ceilings and cement-based substrates, it is advised to:
-
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.
Ready to Use
-
Surfaces are ready for use 2 days after grouting is complete, depending on the type of grout used.
