Store in undamaged, unopened, original sealed packaging in dry conditions at temperatures between 5 °C and 35 °C. Protect from direct sunlight, heat and moisture.

~2.00 kg/l (mixed comp.: A+B+C)

-40 °C min. / +60 °C max.

A : B : C = 2 : 1 : 14 (by weight)

Min.: 3 mm

Max.: 10 mm (locally up to 12 mm thickness possible, for leveling purpose)

+8 °C min. / +40 °C max.

Beware of condensation.
Substrate temperature during application must be at least 3 °C above dew point.

+8 °C min. / +40 °C max.

~75 min. (+25 °C)

The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill components A+B and C before mixing them (i.e. only when application temperatures are above +20 °C).

~90 min. (+25 °C)

The consumption depends on the surface profile and roughness of the substrate and on the size of the tiles and the placing technique (simple placing "floating" or back to back “buttering-floating”).
As a guide:
For 1 mm thickness over 1 m2 area approximately 2.0 kg of material.
One 34 kg unit will cover approximately 5.6 m² at 3 mm thickness.

• Substrates must be properly cured, structurally sound, free of any loose or friable particles, clean, dry and free of any contaminants such as dust, dirt, oil, grease, cement laitance or efflorescence.
• Metal surfaces (steel and iron) should be free from scale, rust, oil and grease.
• Depending on the substrate condition and contaminants to be removed from the surface, perform adequate preparation techniques, such as blastcleaning, in order to remove all traces of any materials that could reduce the product's adhesion to the substrate.
• Any small surface defects and variations in level, profile, or around exposed aggregates for example, can be prefilled and levelled with an additional layer of Sikadur®-43 TA, to a maximum thickness of 12 mm, applied at least 24 h before laying the ceramic tiling. For larger and thicker areas of surface reprofiling and making good, appropriate mortars from the SikaRep®, Sika MonoTop® or Sikafloor® Level range should be used. Cracks in substrates must be identified and sealed appropriately e.g. with Sikadur epoxy resins.
• When laying tiles on non-absorbent or substrates with limited absorbency, such as existing ceramic tiles, painted surfaces etc., check to confirm that these surfaces are all firmly and securely bonded and stable, then use suitable degreasing/descaling products to thoroughly and completely clean the surface.

Mix components A + B together for at least 2 minutes with a mixing paddle attached to a slow speed electric drill (max. 600 rpm) until the material becomes homogeneous. Slowly add component C and continue mixing until a homogeneous mortar is achieved. Avoid entrapping air.

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened/cured material can only be mechanically removed.
