Surface Preparation

The substrate must be clean and free from dust, oil, and all traces of dirt.
It must not be overheated nor frozen.
In hot weather, the surface should be lightly moistened with water just before application.

Product Preparation

Mix 5 parts of the glue with 2 parts of clean water.
Mixing should be done using a mechanical mixer for consistent results.

Product Application

Apply the glue to the lightweight blocks using a notched trowel to achieve a thickness of approximately 3 to 5 mm.
Place the blocks onto the mortar, ensuring full contact.
Check alignment and continue with the next block.
Remove excess material with a wet sponge before it sets.
Important: Do not place blocks if a dry skin has formed on the freshly-applied mortar.
