APPLICATION INFORMATION:

Mixing Ratio

The adhesive used to bond the Schonox AB sheet membrane system is a mixture of
SikaTile 440 Opti-Cure mixed neat with Lanko Latex 751 Additive.

Mixing Ratio of SikaTile 440 Opti-Cure : LankoLatex 751
Rollable Application: 5.5 – 6.25kgs to 5Ltrs – 10m2 coverage
Trowel Application: 7.0 – 8.0kgs to 5Ltrs – 9m2 coverage
Additional powder of up to 1kg of SikaTile 440 Opti-Cure may be added
to the 5Ltr Lanko Latex 751 to reach your desired consistency.
Do not dilute the Lanko latex 751 – use neat.

Trowel Application

Trowel size 2.6mm V notched trowel for board substrates
Trowel size 3.5mm V notched trowel for concrete and screed
susbstrates

Pot Life:

1.5 hours (approx)

Mixing Instructions:

1. Add the Lanko latex 751 additive to a clean mixing bucket.
2. Slowly add the SikaTile 440 Opti-Cure to the bucket while stirring
with an electric mixing drill.
3. Mix the adhesive to a smooth lump free mixture and allow the mixture
to stand or “slake” for 3 minutes.
4. Re-stir the adhesive for an additional 1 minute then the adhesive can
be used.

NOTE: The adhesive may need re-stirring during its pot life, do not add any
additional additive.

Ambient Air Temperature

Not below 5°C & not above 35°C

Substrate Temperature

Not below 5°C & not above 35°C
Avoid application in hot direct sunlight ie >30°C as vapour pockets may
occur.
For external application in expose sun cover with screed or tile as soon
as applicable or cover with a white corflute protection board or similar
immediately after installation.

Applied product will be ready for Covering:

Porous substrates – wall applications – allow 12+ hours
Porous substrates – floor applications – allow 2+ hours
Non porous substrates and compressed cement boards – allow 6+ hours

Drying times are measured at 23°C and 50% relative humidity – use above detail as a
guide only.
Hot climates will reduce drying times and cool or cold climates will extend drying
times.
