Domenii de utilizare

SYNTECH POLIUREA SPRAY-SOFT is particularly used as waterproofing in general; directly on deteriorated and non-damaged bituminous sheaths, concrete or as a protective coating for water containment tanks even with leaks, primary containment, flooring, purification plants, EPS coating, coating and protection of metal sheets, roofs, balconies and wooden sheds and tanks .

Pregǎtirea suporturilor

All surfaces must be free of contaminants, with humidity lower than 3%; the substrate temperature must be at least 3°C above the dew point. The support must offer a mechanical grip on a solid and non-yielding substrate. For this reason, where necessary, a preparation carried out with shot peening, bush-hammering, smoothing or hydro-washing is recommended. If necessary, consult Azichem's technical staff for a correct evaluation. It is recommended to use primers from the SYNTECH POLIUREA PRIMER range, always contacting Azichem technical staff for clarification on the most suitable type to use.

Mod de utilizare

Pure polyurea SYNTECH POLIUREA SPRAY-SOFT requires a bimixer system capable of producing pressure over 180 bar and temperatures above 65° C. Contact the staff for clarification on the best gun to use and on the details relating to the air system . It is recommended to use primers from the SYNTECH POLIUREA PRIMER range and contact the Azichem technical staff for clarification on the most suitable type to use.
