Sikafloor®-20 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.

Homogenise part A with a low speed electric stirrer and then add part B and premix part A and B separately for 30 seconds. Make sure all pigment is uniformly distributed. For the colour pack version, homogenise 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 A neutral, D and B separately for 30 seconds. Make sure all pigment is uniformly distributed.

Start the pan mixer and gradually add part C (aggregate) to the mixed resin parts over a period of 15 seconds. Allow part C to blend for further 2 minutes minimum, to ensure complete mixing and a uniform 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 or Aneutral+B+C+D) to ensure complete mixing. Mix full units only.

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. Sikafloor®-20 PurCem® can be applied using a flat, round edge steel trowel. A short pile roller can be used once or twice, and always in the same direction, to provide a more homogeneous finish to the surface.
