Larsen GPM Gun Applied Mortar is not recommended for flexible or unbound constructions. Ambient temperatures should be above 3 degrees when applying, remember hot temperatures will affect the set time and the product will go off more quickly in the joints and colder temperatures will mean it sets more slowly. Efflorescence and Limebloom are a natural phenomena, affecting all cement based materials, this can be minimised by not working in excessive cold or damp conditions, protecting fresh mortar from excessive additional water.
