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+B+C mixed: ~ 1.97 kg/l ± 0.03 (at +20°C)

Part A : B : C = 1 : 1 : 11.7 (packaging size = 1.5 : 1.5 : 19) by weight. Mix full units only.

3 – 9 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. / +40ºC

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®-29 PurCem® allow:

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

Premix part A with a low speed electric stirrer and then add part B and mix for 30 seconds. Make sure all pigment is uniformly distributed. Use a double paddle (axis) mixer and gradually add 1 part C (aggregate) to the mixed resin. DON’T DUMP!
For the colourpack version, premix 1 part Aneutral with a low speed electric stirrer and add 1 part D to it. Mix until a uniform colour is achieved. Ad 1 part B and mix for 30 seconds. Make sure all pigment is uniformly distributed. Use a double paddle (axis) mixer and gradually add 2 part C (aggregate) to the mixed resin. DON’T DUMP!
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. Mix full units only.

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 pan type revolving mixer.

Apply the mixed Sikafloor®-29 PurCem® onto the ready primed substrate and compact to the appropriate thickness, then finish the detailing profile with a coving trowel or steel float. Apply Sikafloor®-29 PurCem® while the primer is still tacky. If the primer becomes tack free, reapply the primer.

Clean all tools and application equipment with Thinner C immediately after use. Hardened/cured Sikafloor®-29 PurCem® can only be mechanically removed.
