Technical Characteristics

Product based on natural hydraulic lime, natural pozzolan, selected aggregates and other additives. Contains no cement.

Advantages and Uses

  • Mortar for repairing and filling joints in brick or natural stone walls.
  • Suitable for refurbishment due to its high compatibility with traditional systems.
  • For indoor and outdoor application in new-build construction where improved living conditions are required compared with cement-based mortars.
  • Manual or mechanical application.
  • Highly permeable to water vapour, allowing the substrate to breathe.
  • Impermeable to rainwater.
  • High adhesion to the substrate and excellent plasticity.
  • Mortar with a low environmental footprint, manufactured with mineral-origin raw materials. It has an Environmental Product Declaration (EPD).
     

Suitable Substrates

  • Porous, highly absorbent, dry or very hot surfaces must be dampened at the time of application.
  • For refurbishment work, substrates must be properly prepared before application.
     

Application Procedure

  • Add water and mix manually or mechanically until a homogeneous and workable consistency is obtained.
  • Clean the joints between units through their full depth, pre-dampen and apply the mortar with a pointing trowel or suitable tool.
  • For thicknesses greater than 1,5 cm or highly irregular surfaces, fill in layers.
  • For refurbishment work, substrates must be properly prepared before application by removing surface salts and residues from previous work, as well as any unsound or low-strength mortar.
  • If necessary, use Morcem® Cal Base to rebuild deteriorated masonry units or fill joints.
  • Always thoroughly wet the substrates before application.
     

Recommendations

  • Do not apply below 5ºC or above 30ºC.
  • Do not apply where there is a risk of frost, rain, strong winds or direct sunlight.
  • In extreme weather conditions (strong winds or high temperatures), gently spray the product with water on the day after application.
  • Adjust the mixing water, avoiding excess, and allow the required consistency to develop through mixing (3-5 min.). Do not add water to mortar that has already been mixed.
  • The natural origin of the raw materials used in Morcem® Cal mortars may cause slight colour variations between different production batches.
