Dry heat permanent exposure up to +60°C.

Resistant to many chemicals, when fully cured. Please contact Sika's Technical Department for chemical resistance table.

Sikafloor®-1205 provides impermeable protection against common oils, greases, lubricants, aviation fuels and hydraulic oils such as Skydrol. As in all corrosive situations, a full analysis of operating and exposure conditions is required, followed by reference to chemical resistance data, to ensure product suitability.

+10°C min. / +35°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.

< 5 % pbw moisture content.

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

~35 min (+25°C)

Note: Curing times are approximate and will be affected by changing ambient conditions.

Times are approximate and will be affected by changes in ambient conditions, particularly temperature and relative humidity.

* Sikadur® Aggregate series, approx. 0.6-1.0 kg/m².

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage, etc.

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a 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®, Sikagard® 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.

Prior to mixing, stir Part A mechanically. When all of Part B has been added to Part A, mix continuously for 2 minutes until a uniform mix has been achieved. When parts A and B have been mixed, add Part C - Sikafloor® colour pack and mix for a further 2 minutes, until a uniform mix has been achieved. To ensure thorough mixing, pour materials into another container and mix again. Overmixing must be avoided.

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

Rough or unlevelled surfaces need to be levelled first. Use Sikafloor® epoxy based range of products (Thin section epoxy build-up repairs for concrete substrates Method Statement). Sikafloor® BC range can be used as epoxy based underlayments. Contact Sika Technical Department for recommendation.
Coating:
Sikafloor®-1205 as coating, can be applied by shortpiled roller (crosswise). Re-apply second coat by squeegee and then back-roll (crosswise).

For slip resistant finishes:

Apply the base coat first. This coat can then be scattered with Sikafloor® SR 2 or Sikafloor® SR 3 aggregate, by completely blinding at approximately 0.6-1.0 kg/m². Apply aggregate to wet base coat. After initial cure (12 hours at 40°C) the excess aggregate should be removed by brushing or vacuuming. Alternative textures can be obtained by varying the amount of aggregate.
Seal coat:
Sealer coats can be applied by squeegee and then back-rolled (crosswise) with a short-piled roller. Depending on the surface profile, type and density when applied over aggregate, the top coat may consume more material than the base coat to achieve a fully sealed surface.

Remove uncured Sikafloor®-1205 from tools and equipment using a suitable thinner (Xylene / MEK / Acetone). If Sikafloor®-1205 has cured, then it can only be removed by mechanical means.
