Depending on the dimensions of the masonry elements and joint thickness, e.g. approx. 35 kg / m2 for a wall with a thickness of 1/2 brick with a 10 mm joint.
efficiency: approx. 14.5L of mortar with 25 kg of dry mix
The ground and brick elements: bricks, hollow bricks, blocks, etc. must be clean (free of impurities weakening the bond, e.g. fats, bitumen, dust, glues, mortar remains) and dry.

It is unacceptable to "improve" the product by adding sand, cement, etc. Mortar immediately after mixing, apply with a trowel and lightly press masonry elements. Observe the traditional principles of bricklaying technology. Masonry on full joints 10 - 15 mm.
