Store properly in original unopened, sealed and undamaged packaging, in dry conditions at temperatures between +5°C and +40°C. Protect from direct sunshine.

Part A+B+C Mixed :  2.1 ± 0.1 kg/L (at +27°C)

At curing temperature +30°C

Curing Temperature  at +30° C

At curing temperature +30°C, 100% Concrete failure

Part A : Part B : Part C = 2 : 1 : 18 (by weight)

60 mm max.
When using multiple units, one after the other. Do not mix the following unit until the previous one has been used in order to avoid a reduction in handling time.

Sag Flow : Non-sag upto 20mm thickness on vertical surface

+10°C min. / +40°C max.

+5°C min. / +40°C max

+5°C min. / +40°C max

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 parts A+B and C before mixing them (not below +5°C).

~2.1 kg/m² per mm of thickness.

Verify the substrate strength (concrete, masonry, natural stone).

The substrate surface (all types) must be clean and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc.

Steel substrates must be de-rusted similar to Sa 2.5.

The substrate must be sound and all loose particles must be removed.

Concrete / masonry / mortar / stone
Substrates must be sound, clean and free from laitance, grease, oils, old surface treatments or coatings and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface.

Steel
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by blast cleaning and vacuum. Avoid dew point conditions.

Other surfaces (polyester, epoxy, glass, ceramic)
On these substrates pre-apply Sikadur®-31 and then, “wet on wet” apply Sikadur®-53 UF Mortar.

Mix parts A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 600 rpm) until the material becomes smooth in consistency and a uniform colour. Then add part C and continue until mixture is homogeneous. Avoid aeration while
mixing. The, pour the whole mix into a clean container and stir again for 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its potlife.

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