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: ~1.25 kg/l ± 0.03 (at +20°C)

Part A : B : C = 1 : 1: 1.40 (packaging size = 1.50 : 1.50 : 2.10 ) by weight

Mix full units only.

+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°C max.

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 (>1.5 N/mm²).

Before overcoating Sikafloor®-31 PurCem® allow:

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

~0.4 – 1.0 kg/m² (depending on the system build-up)

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
A low speed electric stirrer (300-400 r.p.m.) and an Exomixer-type mixing paddle suited to the size of the mixing container to minimise the air entrapment.

On smooth screeds apply the mixed Sikafloor®-31 PurCem® using a short or medium nap roller directly from a paint tray. On broadcasted screeds pour the material and spread it using a squeegee and then back-roll the excess using a medium knap roller.

Clean all tools and application equipment with Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
