Choose the right type of mortar for the brick The building materials market
offers a large variety of facing bricks, which include: facing brick, clinker,
silicate brick, hand-formed brick, etc. They are characterized by different
properties, of which the behavior deserves particular attention bricks in terms
of water absorption (absorbability). Due to this parameter, bricks can be
divided into: bricks with very high absorbability, with normal absorbability,
with low absorbability and very low absorbability. Therefore, the quick-mix
company went a step further in its research, developing four types of VOR
mortars taking into account the degree of water absorption of bricks. Thanks to
the expanded assortment of VOR mortars, we can brick without risk all kinds of
bricks, regardless of their type and type, purpose, weight or size.

Choose the right type of mortar for the brick
The
building materials market offers us a wide variety of facing bricks, which
include: facing brick, clinker, silicate brick, hand-shaped brick, etc. They
are characterized by different properties, of which the brick behavior in water
absorption (dehydration) deserves particular attention. Due to this parameter,
bricks can be divided into: bricks with very high absorbability, with normal
absorbability, with low absorbability and very low absorbability. Therefore,
the quick-mix company went a step further in its research, developing four
types of VOR mortars taking into account the degree of water absorption of
bricks. Thanks to the expanded assortment of VOR mortars, we can brick without
risk all kinds of bricks, regardless of their type and type, purpose, weight or
size.
2.
Protect the brick from which you will build up
Moistened
bricks - rainwater or groundwater - increase the risk of efflorescence. Also
the moisture contained in the bricks changes their absorption characteristics
which may result in improper binding of the mortar. The bricks should be stored
on pallets and should be protected against adverse weather conditions.
3.
When preparing the mortar, follow the manufacturer's instructions
The
amount of mixing water should be strictly adhered to. Subsequent adding of
water to hardening mortar is not permitted. Observance of the machining time as
well as the start of grouting determines the subsequent final effect of the
masonry.
4.
Do not add any additives or admixtures to the mortar unless this instruction is
mentioned in the instructions for use.
The
use of plasticizers, etc. additives may significantly degrade mortar binding
properties or affect its color. Using them can change the characteristics of
the mortar, which in subsequent actions may result, for example, discoloration,
lack of strength, unwanted shrinkage of the mortar and crumbling and falling
out.
5.
Remember to do the right horizontal insulation - it will protect the raised
element from rising moisture.
Regardless
of whether we are building a house wall or placing fence posts, it is
recommended to create a horizontal damp proofing that will protect the bricks
against rising moisture from the ground.
6.
Work in optimal weather conditions and temperature (from +5 o C to 25 o C). Stop
work immediately if adverse weather conditions occur. Plan your work so that
when setting the mortar, the temperature does not drop below +5 o C during the
setting time
7.
The ready joint should be flush with the brick surface.
The
last stage of bricklaying works is making a weld - an element that affects the
aesthetics and durability of the wall.
Bricklaying
on the so-called slats
- this method has many risks:
-
at least 20% of the brick surface does not carry the load,
-
the joint is not properly hardened,
-
rainwater has access to the inner part of the brick,
-
it is possible to damage the face of the bricks when removing the slats.
Correctly
made joint does not crumble, it allows rainwater to run down the face of the
wall, prevents snow and dirt - it guarantees long-term use of the wall without
dirt and efflorescence.
8.
Making a joint in one cycle with bricklaying
When
laying and grouting in one cycle, remember that grout profiling should take
place at the right moment - it will help you in this so-called "thumb
test" - the water contained in the mortar should not soil the thumb.
When
laying and grouting in separate cycles, remember to leave space for a joint
with a depth of approx. 1. 5 cm .
9.
Properly compact the mortar in the corners
Corners
as elements particularly exposed to the impact of adverse weather conditions
and mechanical damage should be covered with special attention during execution
works.
10
Protect your wall work properly
When
finishing or interrupting work, secure the brick element against adverse
weather conditions (precipitation or excessive sun exposure). Remember,
however, that the protective material allows free ventilation of the wall. A
common mistake is tight wrapping foil posts with foil - this disrupts the
binding process - it prevents evaporation of the water contained in the mortar.
Bricklaying
clinker brick is one of the most demanding building processes - the correct
selection of mortars and the contractor's company guarantees a correct final
result - high aesthetics of the constructed object. quick-mix - as the only one
on the market - offers mortar for clinker bricklaying (also with original Rhine tubag) in 16 colors, with four different parameters
of absorbability of bricks.
