EFFLOCK 20L

Efflock is a high performance additive for cement based building materials to repel damp and lock efflorescence.

 

Efflorescence is caused by water entering masonry. Water travels through the pores and dissolves soluble salts. In cement paste within concrete and mortar, the most problematic salt is known as ‘free lime’ (calcium hydroxide). Calcium hydroxide deposits then absorb carbon (carbonation), and become extremely stubborn to remove.

Efflorescence can also occur from atmospheric deposits or inherent salts in clay and aggregate. Efflorescence from inherent salts is often observed on face brickwork.
