Instructions

Base
  • The temperature of the masonry brick or structure is above > -15°C
  • Brick, natural stone, slate
  • Brick pallets are protected from rain. The bricks must not be wet or covered with snow or ice.
Priming
  • Masonry structures are not primed
Mixing and application of the product
  • Masonry work should not be carried out in direct sunlight, in the rain or during strong winds.
  • The working temperature should be between +5 °C and -15°C. The joint effect of wind and frost must be taken into account.
  • A bag (25 kg) of dry powder is mixed with 2.9 to 3.8 litres of clean water. 
  • Do not add all the water at first. The mixture contains the correct amount of water when the mortar holds its shape and no water rises to the surface.
  • The amount of water must be as instructed in the product card. Deviating from the recommended amount of water lowers the mortar’s strength properties, increases the risk of separation, affects the strength development and reduces workability. 
  • Product is mixed with a mortar stirrer, in a concrete mixer, or with a pan-mixer or a continuous mixer to a smooth consistency. 
  • If the working conditions are very dry or warm, it is possible to improve the adhesion by dampening the masonry joints or bricks. There should not be water drops on the substrate.  
  • Keep the amount of water the same during jointing, because any variations in the amount of water will show as colour differences in the joint.
  • The jointing technique affects the density of the mortar joint. Finish the jointing by sealing them with a brick jointer and removing any excess mortar from the brickwork by brushing diagonally over the joints with a masonry brush.
  • The expansion joints are provided as defined in the structural plans.
  • The working time of the compact mortar is about 3 hours. 
  • When finished working, wash the tools immediately with water.
  • Remove any dried mortar mechanically.
  • After casting you should keep the mortar joints moist by fog spraying for about 3 days depending on the conditions or the target.
  • After casting, you should keep the mortar joints moist at temperatures below 0°C by fog spraying for about 3 days, depending on the conditions or the site
Repointing to a previously masonry joint
  • Available in 20 standard colours. Special colours are subject to order.
  • When repointing, the old mortar must first be removed to a depth of at least 15 mm, but no more than 15% of the masonry depth or according to the designer’s instructions
  • In repointing, the existing mortar joint is removed to a depth of at least 15 mm.
  • The joint is cleaned of dust and dampened.
  • When repointing, add the dry powder to the instructed amount of water and let it stand for about 10 minutes. After that, remix the paste and add masonry mortar to make the paste semi-dry. This mixing method ensures the sufficient air content of the mortar.
  • When repointing, start first with vertical joints and after that work with the horizontal ones. Repoints that are over 20 mm are done in two phases.
  • The working time of a semi-dry mortar for repointing is 1 to 2 hours.
  • After casting you should keep the mortar joints moist by fog spraying for about 3 days depending on the conditions or the target.
  • Bases or masonry units with low water absorption are repointed with Repairing plaster KL 1.2 or Facade coating JSP 1.5.
Other points to note
  • Construction planner instructions and official regulations are to be followed in all masonry work.
  • Not suitable for masonry of the inner shells of fireplaces or wood-burning stoves nor masonry of chimney flues indoors.
  • Masonry mortars may have slight differences in shade between small and big bags, as well as between the mortars intended for winter and summer time masonry, so it is not advisable to change the type of mortar in the middle of the wall.
  • When the temperature drops below -15°C, the masonry area should be covered for seven days to prevent it from freezing.
  • Winter products will be available in the winter season, from 15 September to 1 March. At other times, the products must be ordered separately.
