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.

< 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.

A 46 kg unit of Sikafloor®-1230 will yield ~25.7 L of mixed material.

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

• Vacuum recovery shot blasting machine
• Masking tape / polythene sheets
• Heaters for cold weather work
• Trowels
• Slow speed drill with suitable paddle
• Brushes or short nap hair rollers
• Industrial vacuum
• Scarifier (Errut / Von Arx)
• Grinder
• Overalls
• Lighting
• Spiked roller
• Spiked shoes
• Pin screed

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) witha minimum pull off strength of 1.5 N/mm².

The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc.

Concrete substrates must be prepared mechanically using light grit blasting, captive blasting or surface grinding to achieve an open textured surface.

Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed.

Repairs to the substrate, filling of blowholes/voids and surface irregularities must be carried out using appropriate products from the Sikafloor®, Sikadur® and SikaEmaco® range of materials.

All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

The preferred method for surface preparation of concrete is captive blasting, which gives a well prepared laitance free, vacuum cleaned surface.

Note: Prior to mixing and application, Sikafloor®-1230 should be stored under cover in an air-conditioned environment and protected from extremes of temperature which may cause inconsistent workability, finish and cure times for the mixed material.

Pour the contents of the colour pack into the base (Part A) and then mix the components together using a slow speed (300 – 600 rpm) hand held mixer fitted with a suitable mixing paddle; Collomix DLX mixing head or similar. Mix for no less than 1 minute, before pouring this into a clean large size mixing bucket (min. 30 L) and then adding the Sikafloor®-1230 filler (Part C) whilst continuing to mix until a uniform colour is obtained, free of streaks or lumps of unmixed filler (minimum 2 minutes). Remix the pre-mixed base (Part A) + colour pack + filler (Part C) for 30 seconds and then add the reactor (Part B) and continue to mix until a streak free even colour is reached and there are no visible lumps of filler (Part C), etc.

Always keep the mixing time the same for all batches, to ensure a uniform colour when the product is applied.

Prior to application, confirm substrate moisture content, relative air humidity and dew point. If > 4 % pbw moisture content, Sikafloor® 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 (Xylene / MEK / Acetone), immediately after use. Hardened and/or cured material can only be removed mechanically.
