High impact and mechanical resistance
High glass transition point
Excellent chemical resistance
Non tainting / odourless
VOC free and environmental friendly
Can be applied to substrates with high moisture content (7 days old or mature damp concrete)

Sika Sikafloor 22 PurCem may only be used by experienced professionals.

Application

SUBSTRATE QUALITY / PRE-TREATMENT
The surface must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by vacuum. Pull of strength shall not be less than 1.5 N/mm2. If in doubt apply a test area first.

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

APPLICATION
Prior to application, confirm substrate moisture content, relative humidity and dew point. As a scratch coat Sikafloor®-22 PurCem® can be applied using a steel trowel. As a body coat Sikafloor®-22 PurCem® can be applied using a toothed trowel or pin screed, to the desired thickness, or a steel trowel. Remove air with a spike roller.
