How to use

Application Instructions

Substrate Preparation
The substrate must be dry, firm, well adhered, free of any impurity and must have a grip to ensure the adhesion of the product.

Product preparation
Pour off the water from Kalgraphin Premium pack and keep it to remix the content. Use the remaining contents of the Kalgraphin Premium. Mix the contents of Mortar Base with the remaining contents of the Kalgraphin Premium depending on the desired consistency. Re-add the water from the Kalgraphin Premium pack never more than 1 l. Mix with mechanical mixer until its total homogenization and adequate consistency. Leave 20-30 minutes. Re stir 1 minutes more before applying.

Application method
Apply manually or by projecting, evenly (work thickness: 5-15 mm per day). Level the material to regulate the thickness. Do not smooth the surface to ensure the grip of the finishing mortar. If the substrate has cavities, natural stones, etc., the mortar must be launched prior on the substrate to ensure adhesion and avoid future superficial cracks. If there are supports of different nature, meshes must be used.

Drying
In conditions of 25ºC and 60% relative humidity: 24-48 hours between layers of mortar. The carbonation process mainly occurs during the first 30 days.

Environmental conditions
The work temperature (environment and support) must be greater than +5ºC and less than +30ºC. Do not apply in direct sunlight, strong winds, rain, freezing or on supports heated by the sun.

Coverage
Approximate 20 kg/m2 for 12 mm It depends on the type and condition of the substrate. The exact consumption must be determined by the means of a sampling of the work.

Tools
Mechanical agitator, trowel, double-mix projecting machine, notched trowel or similar, sponge trowel.

Tool cleaning
Clean tools after use with warm water.

Additional Information

  • Do not drench the substrate before application, only lightly moisten if very dry.
  • Careful not to add too much water into the mix.
  • Do not water for hardening, it hardens by absorbing atmospheric CO2.
  • Do not apply to surfaces in constant contact with water.
  • It is recommended to protect the treated surface from rain for at least 4 days.


Caution

  • None in particular for normal use and people who do not have special pathologies.
  • Alkaline product, protect skin and eyes especially.
  • Apply with good ventilation, do not inhale product.
  • Keep out of reach of children.


Storage
Keep in original pack. It should be kept in a dry place and avoid direct sun exposure. Unopened, it may be conserved for at least 36 months from the date of manufacture. After mixing keep the remaining mortar by water casting 1 inches high and seal in a bucket to avoid hardening. (check it every 3 months)
