Baupur 500 Top M colourless matt varnishColourless polyurethane varnish for finishing layers – matt



BAUPUR® 500 TOP M is a two‐component, colourless, matt resin based on water polyurethane dispersion.


As a matting finishing layer in industrial and decorative flooring sys‐tems on the basis of dyed quartz aggregate, mineral‐synthetic aggre‐gate and coloured acrylic chips.

For professional use only.



The surfaces to be protected with a layer of BAUPUR® 500 TOP M must be clean and free from substances decreasing adhesion. BAUPUR® 500 TOP M should be applied on the floor within 48 hours from making the last system layer. If the required period is not be observed, the surface must be thoroughly ground and all dust must be removed from it.


  • Temperature of the foundation – no less than +10°C
  • Relative humidity of the air – max. 75%

NOTE: Special attention should be paid that the temperature of the foundation be at least 3°C over the dew point temperature. Rooms in which the works are performed must be ventilated.

How to mix

BAUPOX® 500 TOP M is provided in original boxes where the amount of component A (resin) corresponds chemically to the amount of component B (hardener). Depending on the final use, the material should be prepared in proper amounts, unconditionally observing the indicated weight proportion.

After adding component B to component A mix it all thoroughly with a slow‐speed mixer (max. 400 revolutions per minute) until a ho‐mogenous mixture is achieved (about 3‐5 minutes).


At the temperature of 20°C and at the relative air humidity of 60‐70%, the material remains suitable for use for 25‐30 minutes after mixing.

  • Increasing the temperature shortens the setting time of the resin and lowers its viscosity.
  • Lowering the temperature prolongs the setting time of the resin and increases its viscosity.


At the temperature of 20°C and relative air humidity of 60‐70%:

  • pedestrian traffic – after 24 hours
  • mechanical loads – after 72 hours
  • complete resistance – after 7 days

Finish layer ‐ matt

Apply BAUPOX® 500 TOP M in an even manner on the foundation with a varnish roller. Roll the material out in two perpendicular directions to achieve a uniform surface. In case of larger works change the roller every 30 minutes.

Consumption: 0,10 - 0,15 kg/m2


Contact of newly made surfaces with moisture (rain, dew, high humidity of the air) will disturb the setting process. The surface may remain sticky for a longer period of time and have a tendency to develop milk‐like pigmentation.


2,5 kg, 5kg, 10 kg,


6 months from the date of production specified on the packaging, when stored on pallets in originally closed packaging and at the tem‐perature from +10 to 25°C.


Tools as well as possible stains should be cleaned when still fresh with water.


BAUPUR® 500 TOP M is classified as a dangerous material. Guidelines as to the safety of work are included in the specification sheet of dangerous chemical preparations.
