Water-based polyurethane cement hybrid

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

Part A (neutral)+B+C+D mixed: ~ 1.75 kg/l ± 0.03 (at +20 °C)  8.5 - 8.7 L volume

1200mg loss - Taber abrasion test

Refer to Sika Technical Department for direction

Excellent resistance to a range of chemicals   - Refer to Sikafloor PurCem chemical resistance chart

Mix full units only.

Scratch coat:                       0.5-1.0mm

Base: (As smooth system) 1.5-2.0mm

Textured system:                2.0-3.0 mm

+10 °C min. / +40 °C max.

85 % 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.

+10 °C min. / +40 ºC

Can be installed on substrates with higher moisture content. No ponding water. Check rising moisture. The substrate needs to be visibly dry and have adequate pull-off strength min 1.5 N/mm2.

Before overcoating Sikafloor®-24 PurCem® allow:

Times are approximate and will be affected be changing ambient and substrate conditions, particularly temperature and relative humidity.

If faster curing is required use Sikafloor PurCem Accelerator.

Addition rate for temps between 18-23 degrees C is 15mls per 15.2kg kit.

~1.75 kg/m²/mm

Premix part A with a low speed electric stirrer and then add part B and mix for 30 seconds. For the colourpack version, premix part A neutral with a low speed electric stirrer and add part D to it. Mix until a uniform colour is achieved. Ad part B and mix for 30 seconds.

Use a double paddle (axis) mixer and gradually add part C (aggregate) to the mixed resin. Allow part C to blend for further 2 minutes minimum, to ensure complete mixing and a uniform moist mix is obtained. During the operations, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once (parts A+B+C) to ensure complete mixing.

Mixing Tools
Use a low speed electric stirrer (300 - 400 rpm) for mixing parts A and B. For preparation of the mortar mix use a double paddle mixer.

Prior to application, confirm substrate moisture content, relative humidity and dew point. As a scratch coat Sikafloor®-24 PurCem® can be applied using a steel trowel. As a body coat Sikafloor®-24 PurCem® can be applied using a toothed trowel or pin screed, or a steel trowel. Remove air with a spike roller.

If creating a PurCem HB-24 textured floor, broadcast desired grade of Silica sand or Sikafloor Broadcast B1 Bauxite to excess.

Be aware of open time to keep up with the initial set time of the Sikafloor®-24 PurCem® base.

Once sufficiently hard to accept a persons weight, remove all brodcast excess by sweeping and vacuuming.

Apply finish coats of Sikafloor 31 or 33 PurCem as per instructions of those TDS.

The mixing and placement of the the Sikafloor®-24 PurCem® base and any finish coats must be carried out strictly in accordance with application guidelines.

Failure to do so will adversely affect set times and the appearance of the finished product related to eveness and colour.

If using Sikafloor®-24 PurCem® as an overlay system on existing resin floors, observe the correct methods for preparation.
