What causes efflorescence?
Efflorescence is caused by water entering masonry. Water travels through the pores and dissolves inherent soluble salts. In concrete, the most abundant of those salts is what's known as 'free lime' which is surplus to the matrix of the concrete. Efflorescence from cement based materials is always the most abundant source, and the most stubborn to remove.
Efflorescence can also occur from inherent salts in clay materials such as bricks, again through water migration. This type of efflorescence is generally more limited, and can often be removed more easily. Surface applied sealers can help to control this type of efflorescence
How does Efflock prevent efflorescence?
Efflock creates a tiny molecular structure within the pores of concrete, which cures with the hydration of cement to form an ever-present water repellent function. Should any small amount of moisture be absorbed, Efflock allows the controlled release of moisture to permeate while preventing salts from migrating to the surface.
We want to use Efflock in our tiling job. How far does 1 litre go?
Using Efflock is at least 80% less than the cost of secondary membranes, and provides better protection. Efflock is designed for tile beds, cement-based tile adhesives and grouts, providing complete protection from all cement based sources of efflorescence.
Efflock is designed to dilute 100 times to use as gauging water in the tile bed*, adhesive and grout.
1 litre bottle = 101 litres of gauging water - (approx. 16m2, including 40mm tile bed, adhesive and grout)
5 litre bottle = 505 litres of gauging water - (approx. 80m2, including 40mm tile bed, adhesive and grout)
20 litre drum = 2020 litres of gauging water - (approx. 320m2, including 40mm tile bed, adhesive and grout)
How do I use Efflock?All you need is a 10 litre bucket and a 1 litre measuring jug. Add 100mls of Efflock to a bucket containing 10 litres of ordinary tap water. Efflock must be added to water first to ensure even distribution before it is combined with dry ingredients.
How long does Efflock take to cure?
Efflock cures with the hydration of the cement. Inclement weather should be avoided for 24 hours.
How long will Efflock's efflorescence and damp protection last?
When used as an additive, Efflock is considered permanent. Please ask about our product warranty.
Does Efflock affect the adhesion of other materials?
Applying Efflock does not change the appearance of any materials, and will not cause detrimental effect to the bond of subsequent adhesives or other coatings.
Does Efflock come in different sizes? 1 litre, 5 litre and 20 litre sizes are available. One litre of Efflock dilutes 100 times, so it is incredibly economical, convenient and safe to transport.
The maximum concentrate formula is deliberate, to minimise packaging which we encourage to be recycled.
Can Efflock remove efflorescence?
Efflock is designed specifically for prevention. We currently don't sell an efflorescence remover, but may introduce one in future. There is already a huge range of efflorescence cleaning products available on the market because of course, efflorescence has been a big problem for a long time.
Efflock products are now available at Nerang Tiles.
