Application:

building walls and partitions with ceramic and silicate bricks, for indoor and outdoor applications. Siltek M-1 (50,75,100) mix is efficient for laying quarry stone and for foundation and basement walling. 


Composition:

high quality cement PC I-500, graded aggregates, modifying additives.


Surface preparation (according to DSTU-N B А.3.1-23:2013, DSTU-N B V.2.6-212:2016):

brick surface should be strong, with no considerable damage, and free from dust, dirt, oil and any substances that reduce adhesion.


Preparation of mortar mix by machine:

prepare a mechanical unit according to Operating Instructions;

set the desired water flow according to the proportion;

supply mortar mix to the site using mixing pump or working vessel.


Preparation of mortar mix by hand:

pour water in a clean working container at the rate of:

– 3.9 – 4.2 l of water per 1 bag of Siltek M-1-50  (0.13 – 0.14 l per 1 kg of dry mix);

– 4.2 – 4.8 l of water per 1 bag of Siltek M-1-75 (0.14 – 0.16 l per 1 kg of dry mix);

– 4.8 – 5.1 l of water per 1 bag of Siltek M-1-100 (0.16 – 0.17 l per 1 kg of dry mix);

gradually add dry mix and stir with a low-speed mixer to obtain homogeneous, pasty mass without lumps;

leave the mixture for about 3 to 5 minutes, then stir again.


Application process:

using a trowel or metal putty knife apply mortar mix onto the work surface (the thickness of the layer applied depends on the type and quality of bricks) and float;

when laying bricks do not press them strongly to the surface taking into account mortar mix plasticity (they may be adjusted within 2 minutes, if necessary)

recommended layer thickness between the bricks is 8 to 15 mm;

period of mortar hardening depends on the type of bricks and weather conditions;

wash tools thoroughly upon completion or stoppage of work; 


Packaging:

paper bags with inner polyethylene layer, net weight 30 kg, or silo with a volume of 22 m³.


Storage:

in undamaged packaging, on pallets, in dry place at temperatures not above 40 °C and air humidity not above 75 %. Guaranteed shelf life is 12 months from manufacturing date indicated on the package.


Safety Rules:

keep out of the reach of children;

while working protect the respiratory system;

avoid contact with skin;

in case of contact with eyes rinse with clean water and, if necessary, seek medical advice.


Caution:

it is recommended to perform all work at the surface and air temperature of + 5 °C to +30 °C and relative humidity of 55-65 %;

do not use in laying products made of gypsum;

in the hot season it is recommended to moisten the brick surface before masonry;

the surface of the bricks before masonry should be free of ice deposits (additional heating possible). It is recommended to prepare mortar mix in plastic container using heated water (up to +35 °C).
