Note: Advanced Spirito Libero recomends that our entire range of lime based natural materials is used only by highly skilled or licensed tradespeople with extensive experience in this field. It is the responsibility of the applicator to understand the application method and the procedure involved in order to obtain a satisfactory outcome. Advanced Spirito Libero recomends that architects, builders and clients appoint only experienced applicators in the relevant lime-based materials to ensure they'll be able to deliver the same finish as per the sample shown.

As with any lime-based material this product may change the appearance over time due to the ageing process caused by weather conditions"
To slow down this process the use of siloxane impregnating sealer is recomended over time.

For exteriors please protect treated surfaces from raining during application and for the time required to allow product to fully harden (48h), fail to do so, some trace of efflorescence might appear and no warranty will be applied.

Ensure that a sufficient quantity of the same batch is available to complete the entire job or at least to complete whole sections that will not reveal differences in shade.

Advanced Spirito Libero provides no warranty expressed or implied against damage due to movement of the substrate structure.


product mixing

TADELAKT is sold in a white powder form, and it has to be mixed with 30% of clean water (max 3L per bucket).  

In case of necessity or in case of high temperatures, it is recommended to wash the surface with water, before to apply TADELAKT.





To obtain a better job it is advisable to use a venetian plaster trowel, trying to use it in an uniform and homogeneous  way.





It is possible to apply the second coat only when the first one is totally dry and it is important to apply it in a homogenous way creating a smooth surface without any lump or imperfection. Be careful to not make it polished.



The last coat should be applied when the previous one is not totally dry, pressing the product with the polishing trowel, which has to be hold in a quite inclined way, and smoothing the surface without polishing it (as a normal marmorino), but keep it a bit rough.

In the original countries of this product, TADELAKT is applied using specific flat and very hard stones.









Allow the surface to dry for at least 48hours. Then apply the soap with a venetian plaster trowel or sponge. Apply the product more than once on wet until it is completely absorbed, trimming perfectly. After 24 hours, run a cloth on the surface to remove the superficial film of dust of soap, which was not absorbed.







After 48 hours apply 1 coats with a brush until saturation


The ambient temperature must be between +10°C and +30°C, while the relative humidity must be less than 85% for at least a day. It is better to avoid this phase on windy days or when the sun is shining or when it is raining.
