Best Uses

Sika Sikafloor 29 PurCem is used as a coving mortar, detailing and vertical rendering with Sikafloor® PurCem® floor systems.

  • Good wear resistance
  • High mechanical and impact resistance
  • High softening point
  • Good chemical resistance
  • Non tainting /odourless
  • Fast curing
  • VOC free and environmental friendly
  • Can be applied to substrates with high moisture content (7 days old or mature damp concrete)

Sika Sikafloor®-29 PurCem® may only be used by experienced professionals.

Application

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.

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 colour pack version, premix 1 part A neutral with a low speed electric stirrer and add 1 part D to it. Mix until a uniform colour is achieved. Add 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 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. 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 Pur-Cem® while the primer is still tacky. If the primer becomes tack free, reapply the primer.
