Installation Procedure

Suggested Installation Procedure

Order only the amount of material that can readily be installed.
Unload pallets using pallet forks either forklift or pallet fork mounted on a crane. For safety reasons it is not advisable to use crane strap or slings.
Storage should be easily accessible to truck or lift truck at all time.
If possible, drop-deliver the product right to material staging areas.
Storage area should always be away from other construction activities and on a flat-graded area that is not susceptible to standing water, erosion or settling to avoid damages to products.
Always keep the product covered and banded until ready for installation.

Levelling Mortar Bed

The first layer must be horizontal and it is laid on a bed of ordinary mortar. If the surface is uneven a general purpose masonry mortar is used. The grouting grooves in the butt ends of the blocks are filled with AAC Thin Joint Mortar. After the hardening of the first layer the work is continued with AAC Thin Joint Mortar using a mortar sledge or a notched trowel with notches e.g. 6 x 6 mm. The grouting grooves in the butt ends of the blocks are filled with AAC Thin Joint Mortar. The units are laid in overlapping bond pattern. The width of the joint is determined by the notches of the mortar sledge or the notched trowel and is normally 2 – 3 mm. If the blocks are very dry, and if the conditions are very hot, they are moistened prior to the masonry work. The grouting grooves are filled with AAC Thin Joint Mortar.

Wall ties and lintels are used according to the instructions by the designer for inclusion of reinforcement. Reinforcement grooves are moistened and filled with AAC Thin Joint Mortar so that they are completely covered with mortar. Use spirit level and mason´s line to ensure that the units are laid straight and plumb. The AAC Thin Joint Mortar has a certain open time during which the position of the unit can be adjusted e.g. with a rubber hammer.

Excess mortar, squeezed out from the joints, is immediately removed as the work proceeds and the wall surface is cleaned with a masonry brush after the mortar has dried but before it has initially set. Excess hardened mortar on the wall surface will disturb tiling or coating of the wall. For the filling of the grooves for plumbing and electrical wiring, general purpose masonry mortar is used.
The tools are cleaned with water directly after using. Parin thin bed mortar doesn’t require curing with water.
