Approximately 12 months from date of production

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5°C and +30°C.

~1.79 kg/l (mixed, at 25°C)

~100 %

Min. 2 mm
Max. 4 mm

+10°C min. to +30°C max.

80 % r.h. max.

Beware of condensation!
The substrate and uncured floor must be at least 3°C above dew point to reduce the risk of condensation or blooming on the floor finish.
Note: Low temperatures and high humidity conditions increase the probability of blooming.

+10°C min. to +30°C max.

< 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM-measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).

As a general guide:

~1.8 kg/m²/mm applied as a self-smoothing wearing course.

For additional and more detailed information please refer to General Method Statement.
Always prime the surface before application of self-smoothing layer.
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Sikafloor®-1230 components are supplied in preweighed packs which should not be split or divided. Always mix a full kit.

The concrete substrate must be sound, with a minimum compressive strength of 25 N/mm² and a minimum pull-off strength of 1.5 N/mm². The substrate must be clean, dry, and free from all contaminants such as dirt, oil, grease, coatings, sealers, and surface treatments. Concrete surfaces must be prepared mechanically using suitable methods such as light grit blasting, captive blasting, or surface grinding to achieve a clean, open-textured surface. All weak or unsound concrete must be removed, and any surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, including the filling of blowholes, voids, and surface irregularities, must be completed using appropriate materials from the Sikafloor®, Sikadur®, or SikaEmaco® product ranges. Before applying the product, all dust, loose, and friable material must be completely removed from all surfaces, preferably by vacuum cleaning or brushing. The preferred method of surface preparation for concrete substrates is captive blasting, as it provides a laitance-free, well-prepared, and vacuum-cleaned surface.

Prior to mixing and application, Sikafloor®-1230 must be stored under cover in a dry, air-conditioned environment and protected from extreme temperatures. Exposure to heat or cold may affect the product’s workability, finish, and curing characteristics. Pour the entire contents of the Colour Pack into the Base (Part A) and mix thoroughly using a slow-speed electric drill (300–600 rpm) fitted with a suitable spiral or helical mixing paddle. Mix for at least one minute until a uniform consistency is achieved. Transfer the pre-mixed material into a clean, large mixing container. While continuing to mix, gradually add the Sikafloor®-1230 Filler (Part C) and mix until a homogeneous, streak-free colour is obtained, free from lumps of unmixed filler (minimum two minutes). After obtaining a uniform mixture, remix for approximately 30 seconds, then add the Reactor (Part B) and continue mixing until a consistent, even colour is achieved and no streaks or lumps remain. Always maintain the same mixing time and procedure for all batches to ensure uniform colour and finish throughout the application.

Prior to application, confirm substrate moisture content, relative air humidity and dew point. If > 4 % pbw moisture content, Sikagard® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.

Primer:
Make sure that a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Apply primer by brush, roller or squeegee. Preferred application is by using a squeegee and then backrolling crosswise.

Smooth wearing course:

Mixed Sikafloor®-1230 is poured and spreaded evenly by means of a serrated trowel or pin rake.
After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish.
Roll immediately (before material begins to gel) in two directions with a spiked roller to ensure even thickness.

Clean all tools and application equipment with suitable thinner, immediately after use. Hardened and/or cured material can only be removed mechanically.
