You will need
  • – lightweight aggregate blocks;
  • – cement;
  • – sand;
  • – lime;
  • – wooden slats;
  • level;
  • tool bricklayer (trowel, kirochka, plumb, etc.).
Prepare the base for stacking blocks. If it is a strip footing, ensure the levelness of the surface, eliminate local irregularities and position the waterproofing. If laying waterproofing is not required, it is strongly advisable to ensure horizontality. Local irregularities of the solution align the first seam.
Install on the corners of walls Reiki porjadovki. Their role can execute smooth wooden slats installed vertically at a distance of 5-8 mm from the corners and lines of the exterior walls. Mark on the rails the zero point corresponding to the level of the base, and apply a marker for dividing corresponding to the rows of masonry. The distance between the marks should equal the sum of the height of the block and thickness of the weld (10-12 mm). Pull the cord between the divisions of the first row – so that the distance from the outer surface of the wall was 5-8 mm.
Prepare mortar. Can be used as lime-cement and cement-sand mixture. However, the first is more warm, pliable and longer retains its working qualities. The ratio of components in cement-sand mortar may be 1:4 or 1:3 (cement:sand), lime-cement – 1:0,2:3 or 1:0,3:4 (cement:lime:sand).
Moisten the blocks with water. This can be done by spraying them with tap water from a hose in the pile. The degree of humidity must be such that the surface of blocks did not remain dry places, and at the same time all the water was absorbed by the surface of the blocks.
Put the solution on the base of the bed, the width of which should be a few inches narrower than the width of block, height of about 20 mm. apply the Solution right under some blocks, if the length of the wall is small (not more than 3 m), on the wall.
Lay the first block, starting from the corner of the wall. Press it into the mortar, simultaneously exposing its vertical edge at the position of Reiki-porjadovki, horizontal – on the tense cord. The final thickness should be 10-12 mm. Pick a trowel mortar, extruded from the seam.
When laying the second stone is put on its end surface facing to the previous block, mortar and push the stone on the wall, while pressing it to the base, and the previous block. In the same way placed all subsequent stones the first row with the obligatory leveling them up on the cord.
Reinstall the cord to one notch above. Laying the second row start with where you ended the first row. Provide shear joints (bandaging of seams) of the second row relative to the first pablaka. If the wall thickness is placed in a block, it is necessary to ensure the ligation and also by the width of the wall. Ie you need to put a row of the stretcher (long side along the wall), the second – poke (short side along the wall). The overlap of the seams in adjacent rows (height) should be a quarter of the block. Pay special attention to the bandaging of seams on the corners.
