Installing insulation screed without mesh?

Standard insulation screed can be installed without a StaenisGrid, but on top of that there must always be a sand-cement screed or floor screed.

If you install the standard insulation screed with the StaenisGrid, you can place flatter insulation boards on top of it (+ screed floor) or screw OSB directly onto the grid.

Tiled insulation screed should always be installed with the StaenisGrid. This creates a flat surface suitable for tiling and is reinforced to protect your tiles.

If you install your tileable insulation screed without the StaenisGrid, the insulation screed will be more than 2 cm uneven, making tiling impossible and making it difficult to estimate the height in advance.

Also keep in mind that tileable insulation screed contains much more cement and you will therefore mix it with more water. As a result, the tileable insulation screed shrinks more and is more likely to bulge during drying. The squares of the StaenisGrid absorb this, so that the height remains the same and you can always tile the floor afterwards.
