Attention:  


Construction prohibited when humidity is greater than 85%RH;

The curing agent component meets the water vapor extremely easily to deteriorate, saves must seal dry.



User's guidance: 


After mixing, the material must be poured all over the floor and then scraped, so as to avoid the bottom of the aggregate and the poor surface effect;

Adopt the construction method of batch scraping firstly and then roller coating, and evenly collect the short wool or sponge roller;

Dosage strictly controlled in 0.08~0.1kg/m2, avoidaccumulation, otherwise foaming serious;

This material has very high requirements for construction. It must be trained by our company before use.



Storage: Ideal storage conditions is 5-35 ℃ in cool and dry place, avoid sun exposure.
