Ardex Optima 2 Part Tile Adhesive Kit

 

DESCRIPTION

ARDEX Optima is a premium grade two component wall and floor tile adhesive with exceptional adhesion qualities.

The unique formula enables it to be used over many difficult substrates including sheet timber flooring. ARDEX Optima is suitable for all types of ceramic tiles and moisture insensitive natural stone on internal or external, wall and floor applications and is also suitable for continuous immersion applications such as swimming pools.

ARDEX Optima has a high initial grab which reduces the need for support in wall tiling applications, and is classified as a highly flexible adhesive, S2 in accordance with ISO 13007.

FEATURES

Exceptional bonding – suitable for use over a number of difficult to adhere to surfaces
Highly water resistant – will not deteriorate in constant water immersion applications such as swimming pools
Highly flexible – S2 classification
White – suitable for use with translucent tiles
High initial grab – reduces the need for support in wall tiling applications Suitable for wall and floor tiling
For internal and external use

FOR FIXING (TILE TYPES)

Ardex Optima is suitable for use with fully vitrified and ceramic tiles, porcelain, concrete stone tiles e.g. terrazzo, natural stones (excluding moisture sensitive), glass and porcelain mosaics.

ARDEX Optima can also be used as a primer when tiling over sheet plywood and particleboard with ARDEX X56.

TO (SUBSTRATES)

• Rendered brick and blockwork
• Tilt up and pre-cast concrete mechanically prepared concrete, aerated concrete and cement renders
• Powder coated cladding, galvanised, stainless steel(degreased) and brass
• ARDEX liquid applied undertile waterproofing membranes and Butynol
• Medium density fibre-cement sheet, compressed fibre-cement sheet, plasterboard
• Roughened fibreglass
• Existing ceramic tiles (thoroughly cleaned) • Sheet timber flooring

SUBSTRATE PREPARATION

The surface being adhered to must be clean, firm and free

of dust, dirt, oil, grease, curing compounds, release agents and other barrier materials, as well as being strong enough

to support the weight of the tiles being fixed. Ensure surfaces are dry before tiling, with no residue or permanent damp. Ensure that the substrate’s required cure/drying time, as given in the relevant part of AS 3958, is allowed to elapse prior to fixing the tiles. Prime porous substrates with

ARDEX Multiprime.

Concrete

This includes precast, in-situ and wood floated concrete. As concrete exhibits drying shrinkage, allow to cure for at least 4 weeks prior to tiling. Any surface laitance, concrete sealers, curing compounds, and other materials shall be removed from the surface prior to tiling. The surface shall be true and level and pitched to drains where required. The concrete should have adequate surface profile (e.g. broom finish) to provide

a mechanical key. Smooth surfaces and/or dense concrete greater than 35MPa must be mechanically prepared to CSP2 profile prior to tiling.

Cement Render/Screeds

New renders and screeds should be finished with a wood float to the required surface regularity. Allow render/screeds to cure for 7 days prior to tiling.

Plasterboard/Medium Density Fibre-Cement Sheet

Provided that these boards are firmly and rigidly fixed to adequately support the tile bed, tiles can be fixed directly. Please ensure the surface is completely clean. Priming with ARDEX Multiprime is recommended over fibre-cement sheets, followed by taping of sheet joints with PVC ducting tape. Priming is not usually necessary for plasterboard except when a jointing compound is used, the compound should then be primed with ARDEX Multiprime.

Compressed Fibre-Cement Sheet

Internal Applications

These sheets must be fixed strictly in accordance with manufacturer’s instructions and be deemed suitable for the application by the manufacturer.

Tiling over compressed fibre-cement sheets for external flooring applications should be carried out as per sheet manufacturer’s recommendations and Australian Standard AS 3958.

Existing Ceramic Tiles

These include sound, clean, glazed and unglazed tiles. If the area to be tiled is internal, tiles can be directly fixed using ARDEX Optima without mechanically grinding the glaze, following cleaning with sugar soap using an industrial grade scourer. Rinse and allow to dry. In permanently wet areas and externally, consult ARDEX Technical Services.

Autoclaved Aerated Concrete (AAC)

Remove loose particles from the surface.
Apply two coats of ARDEX Multiprime and allow to dry.

Existing Vinyl Tiles

Ensure tiles are well bonded to the substrate. Remove wax, polish and any loose tiles. Clean with sugar soap and a scourer then rinse with warm water.
Caution: Old vinyl tiles may contain asbestos and require special handling.

Metal Surfaces

Remove rust and mill scale mechanically and any oil or grease with a solvent cleaner. Galvanised metal should be cleaned using high pressure water and scrubbing with a stiff broom. Prime with an appropriate metal primer that does not contain free metallic zinc or aluminium powder.

Painted Surfaces

Thoroughly remove previously painted surfaces mechanically, do not use paint stripper or solvents. Allow surface to dry after cleaning.

Blockwork and Brickwork

Brickwork and blockwork must be sound, flush and level. Brickwork must be rendered, where other surfaces are not smooth and level the wall must be rendered. Ensure all voids and raked out mortar joints are filled and excess mortar pared back. Prime with ARDEX Multiprime. Do not use Optima as a render to smooth walls.

Butynol

Butynol must be cleaned to remove any dust or contaminants using ARDEX WPM 290. If more stubborn soils remain, contact ARDEX Technical Services for advice. Allow surface to dry before the commencement of tiling. Use a 12mm notched trowel to achieve a dry bed thickness of at least 4-5mm at 60oC and full coverage.

Fibreglass

Gel coat must be removed to expose at least 80% of raw fibre. Remove loose dust and allow to dry prior to a skim coat being applied, allow to dry then tile. Not suitable for preformed shower bases, spas or underwater applications.

ARDEX Liquid Applied Undertile Waterproofing Membranes

ARDEX undertile waterproofing must be applied according to instructions and thoroughly dry prior to tiling. For more information about swimming pools consult Technical Bulletin TB-198.

GROUTING

Grouting can proceed once the tile bed has hardened sufficiently so that tiles will not be dislodged. Light foot traffic and grouting may be allowed after approximately 8 hours
and full traffic after approximately 24 hours at 23oC and 50% relative humidity. Allow longer for dense tiles/substrates, humid climates and low temperatures.
The tile joints should be grouted with the appropriate ARDEX grout. Where movement is anticipated, mix ARDEX cement based grout with ARDEX Grout Booster.

COVERAGE

 

As a tile adhesive
Coverage for the Mini and Large kits of ARDEX Optima is approximated in the below table:

Mini Kit.    6mm trowel (3m2).           10mm trowel (2m2)
Large Kit  6mm trowel (16m2).         10mm trowel (10m2)

As a general guide, use a 6 x 6 x 6mm notched trowel for walls and 10 x 10 x 10mm notched trowel for floors. The coverage will vary depending on substrate condition, tile type and application technique.

 

As a primer over timber floor

1kg of mixed ARDEX Optima slurry is sufficient for approximately 1.2m2 when applied on the floor with a pre- wetted 15mm nap roller.

PACKAGING

ARDEX Optima mini kit powder is packed in poly bags – net weight 5kg and liquid is packed in plastic container – net weight 1.7kg. ARDEX Optima large kit powder is packed in poly bags – net weight 6 x 5kg and liquid is packed in a plastic pail – net weight 10kg.

SHELF LIFE

ARDEX Optima has a shelf life of 12 months when stored in the original unopened packaging, in a dry place at 23oC and 50% relative humidity.
Pay attention to the following:
Excepting external grade plywood, timber is considered an unsuitable substrate for tiling in external situations due to moisture instability.
Do not use ARDEX Optima over timber in external situations.
The integrity of bitumen membranes cannot be guaranteed once tiled over and “bleeding” may occur.
Bitumen is not considered a suitable surface to be tiled using ARDEX Optima.
For setting of moisture sensitive natural stones, please refer to products in the ARDEX Natural Stone System.
ARDEX Optima is not suitable for use over epoxies (except ARDEX WPM 300), polyurethanes and chlorinated rubber due to the ‘anti-adhesive’ nature of these products.
Before any substrate preparation, installation or finishing methods relating to ARDEX product are undertaken, please be aware of any potential risks and use appropriate PPE (personal protective equipment). This may involve contacting substrate manufacturers for Safety Data Sheets.
