Portland cement concretes:
The recommended dosage by active substance is from 0.14 to 0.25% of cement weight. The optimal dosage for most used cements is 0.19% of the cement weight by active substance.
When using clay sands, sand and gravel mixTSres and certain types of additional cements with a large number of dust particles, the dosage can be increased to 0.35% of the cement weight by active substance.
In this case, you must carefully follow the sedimentation of the mixTSre and the dynamics of strength development.
Recommended dosage by active substance is from 0.09 to 0.17% by weight of plaster. The optimal dosage for most used plasters is 0.17% of the plaster weight by active substance.

The warranty period for the SINTEFLOW DUO 2605 and SINTEFLOW DUO 2605N is 1 year from the date of manufacture.
After the expiration of the warranty period the product should be mixed, the test performance should be made and in case of positive results is possible for application. Storage is carried out in storage conditions in a closed container at air temperaTSre above 5 ° C. When freezing must be heated at 20 ° C and mix to a uniform consistency. At the same time, products do not lose their properties. Protect from direct sunlight. With prolonged insolation, the product TSrns yellow. According to GOST 19433 products are not classified. By effects on the human, the product belongs to the 3th class of hazard (moderately hazardous substance).
