ACICO Block Laying

The first course should be laid in cement mortar bed of thickness about 1 to 3 cm. This course must be laid correctly for fast building progress in the following courses. In all next courses ACICO blocks are best laid with ACICO thin-bed mortor (glue).

For mixing the thin-bed mortar with water, it is best to use ACICO stirrer driven by a slow-speed drilling machine. After thorough mixing, the mortar is ready for use.

First dust and loose particles must be brushed from the horizontal joint surfaces. Then apply thin-bed mortar to the horizontal surfaces with a suitbale ACICO plane-block trowel of width equal to block width.

While adjusting the mortar consistency, make sure that during application the thin-bed mortar flows easily through the teeth of the plane-block trowel over the full surface. The consistency should be such that the mortar strands visible on the horizontal joints after applying mortar by trowel cannot mingle. That means the teeth should remain visible.

Bond dimensions must be adhered to. The vertical joint of the lower course must be staggered at least 10 cm relative to the vertical joint of the overlaying course. Now use the rubber hammer to align accurately edge to edge and tap firmly into place.

A few blocks should be removed randomly immediately after laying to check whether mortar is spread over the full surface or not. In summer season, it is recommended to wet the block before applying the glue.

Differences of heights in a course can be adjusted by using plane board. If these differences are not more than 2-3 mm adjusting by thin bed mortar is also possible. All follow-up work on walls of ACICO blocks is carried out in the usual way.
