Instructions for use

Surface preparation

For grouting works on existing facades prepare the substrates as follows:

  • Remove old grouting material if any
  • Wash the substrate with water to dampen it before starting application

Product preparation

Mix one bag of 50 kg of webercal stone with 6 to 8 liters (half quantity is required for 25 kg bag) of clean water using an electric mixer with low rotation speed (<300 rpm).

Continue mixing until a homogeneous paste of smooth creamy consistency is obtained. Let the mix rest for a few minutes before starting the application

Product application

webercal stone is applied using a stainless steel trowel in a maximum thickness of 3 cm. During application, the temperature should be between + 5°C and + 35°C. After application, protect the freshly applied mortar from direct sun shine and cure it twice a day for 3 consecutive days.
