Ready-to-use product to be applied manually. Spread the mortar in the center of the hemp block for at least 2/3 of the surface with a thickness of about 1 cm, necessary to regularise the surface for the next course of masonry. Before proceeding with the laying of the bedding mortar, the hemp block must be wet by nebulising with clean water. Once the wall is finished, the mortar joints between the bricks can be filled and tooled. Tooling the joints allows to completely eliminate the thermal bridges generated by the bedding mortar and offers a perfect uniformity of material on which the plaster will be applied. It is possible to lay the blocks up to about 3m high, without any problem. For greater heights using blocks of smaller thicknesses, it is advisable to proceed with the laying of about 1.5-2m in height, wait for the bedding mortar to “set” and then continue.
