Prime concrete substrates with Vetoprime UP360 or Vetoprime EP490.

Mixing Vetotop UC363

In a separate mixing vessel, use a slow speed mixer to mix the base, hardener for 3 minutes. Mix these components in the quantities supplied, ensuring that all containers are scraped clean. Do not add solvent thinners at any time.


Apply Vetotop UC363 by a pin leveler or airless spray to the dry surface. The application should be at a rate of 1.25 m2/liter per coat.

The application should not be carried out when relative humidity exceeds 75% or when the surface temperature to be coated less than 3°C above the dew point.

Vetotop UC363 can be applied as a single coat or dressed with Vetograin products to give a slip-resistant finish.

For more information, please refer to Vetograin Technical Data Sheet.

Expansion Joints

Repair all necessary surfaces before application by using epoxy mortar from the Vetorep ER range. New concrete floors shall be at least 28 days old with a moisture content of less than 5% (shall earlier application be required testing of substrate for moisture conditions shall be made).
