Mortars – the use of special mortars and their advantages
| Special cements for tiles | Coloured mortar mixtures |
 Using special mortars
   When using mixtures for facing masonry, the same consistence must be used for pointing (to avoid the occurrence of colour shades!). The bricks in the masonry must be bonded, i.e. the vertical joints of every subsequent course must be shifted by 1/4 of the brick length, however 4.5 cm as a minimum.

The joint thickness is selected so that the joint and brick dimensions meet the standard. In general, vertical and horizontal joints 1 cm thick are used. The masonry must be constructed using mortar of 3.5-7 MPa pressure strength. Frost-resistant means are not allowed. When constructing face masonry with mortars, walls are built and pointed simultaneously. Mortar is applied in layers thicker than usual in building. When laying bricks, remove the mortar forced out of joints with trowel.

After mortar setting, finish the joints using a wooden peg, a piece of hose, a pointing trowel, etc. The joint colour depends on the mortar consistence and the joint finishing method. Joints should be finished on consistently set mortar.

 Advantages of special mortars
  • When erecting and pointing is carried out simultaneously, subsequent pointing is unnecessary; wages and cost of scaffolding are spared; the joints are homogeneous and prevent mortar crumbling away.
  • The ability of mortar to bind water makes the mortar more plastic, better and more quickly processed.
  • The filling of joints with mortar over the whole area prevents the occurrence of voids and empty spaces, improving the resistance of joints to rain.
  • The full connection of mortar and brick prevents the occurrence of failures and avoids subsequent repairs.
  • The time-intensive brick soaking process in unnecessary.
  • No additional cost of cleaning the fair-face brickwork
  • Almost no waste generated
  • Special mortars limit the occurrence of white laitance on facing bricks and tiles.
  • The ability of mortar to bind water depending on brick absorbability

   The application of these mixtures is similar to the one in coloured mortars. Detailed information is available in our special leaflets and technical sheets.
