NIPPON SZ

50 kg cement*, 250 ml Nippon SZ, max. 20 litres water, 200 litres styrofoam filler. Mixing time: at least 90 sec.
CAUTION: 350 ml standard screed mixture must under no circumstances be exceeded!

After delivery to the site the levelling filler must be distributed and levelled evenly.
The filler must be compacted with a hand rammer.
At layer thicknesses over 10 cm, application and compaction must be performed layer by layer.
All relevant standards, especially DIN 18 353, DIN EN 13813 and DIN 18 560, customary industry practices and standards and the technical instructions of the manufacturer of the filler materials must be observed. Seal open containers airtight immediately after use and use the contents as quickly as possible.

Not suitable for levelling fillers with mineral, absorbent aggregates (levelling fillers with granulated pumice stone, perlite, expanded clay) as well as grit fillers. Levelling fillers modified by the manufacturer are not suitable either.
Layer thicknesses over 200 mm considerably prolong the stated drying times. It is difficult to specify the exact drying times. Practical experience has shown that the drying time is about 2 days longer per five cm additional layer thickness of the levelling filler. This information is not binding. Please see the information on moisture measurement in section 6.

For application, the same conditions largely apply as for screed application.
It is possible to use condensation dryers to accelerate the filler drying process, especially at layer thicknesses over 200 mm.

The moisture can be measured with a CM measuring device. To do so, the weight of 20 g sample material (taken over the total cross-section of the levelling filler) is sufficient. Workability for laying the insulation is obtained if the CM value is ≤ 9 %.

In case of uneven application thicknesses and thicknesses above 200 mm it is recommended to select a representative surface area and to cover about 2 x 2 m of the area with a thick transparent PE foil fixed airtight with masking tape. The foil should be left in place for at least 2 days. The degree of dryness is sufficient if no condensation has formed beneath the foil.

Do not allow RETANOLS® to enter the aquatic environment, sewage system or soil. Recycle completely empty containers (non-drip and open).
