Surface preparation
The support, where NEOFIL BLOCK will be applied, must be perfectly clean, solid, compact and free from grease substances.
Mixing
To prepare the mixture, pour in a container 10 to 10.5 Liters of clean water. Add a bag of 50 Kg of NEOFIL BLOCK, then mix to get a homogeneous lump free consistency mix.
Let the product rests for about 5 minutes and remix shortly before use.
Application
Saturate the block surface with water before applying the adhesive mortar any excess water should be removed.
Place the first line of blocks on concrete slab using a traditional cement mortar.
Apply NEOFIL BLOCK with special toothed trowel and then position the blocks verifying their alignment. Remove possible excess of mortar before it hardens.
Ensure that the adhesive spread on the blocks has not formed a superficial film. In this case apply fresh mix with the toothed trowel.
NEOFIL BLOCK should be applied in a thin layer to enable the continuity of thermo-insulation of the blocks.
Leave a space of about 2 cm between the top of block wall and the bottom of slab or beam in order to avoid formation of cracks along the wall. This cavity should be filled with compressible material (see relative technical data sheets).
After full curing of the block wall, plastering may start using an appropriate plastering product such as RASANTE P20.
Cleaning
Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.
