Attention
Construction prohibited when humidity is greater than 90%RH;
Ensure that the concrete reaches the maintenance standard and the moisture content is lower than 8% before
construction carried out；
The concrete foundation must be polished and cleaned thoroughly before construction carried out；
The reaction is very fast, After stirring, all must be poured on the ground to prevent the heat from melting in the
bucket.
User's guidance
Mix the two ingredients strictly in proportion and stir well; short-stem roller or Trowel construction;
Coating amount controlled by 0.1-0.15kg/m2.
Storage/Shelf Life:Ideal storage condition is 10-35℃in cool and dry place, avoid direct sunlight. / One year
