How to remove efflorescence
Read more →Efflorescence is very simply caused by the action of water entering masonry. That water then dissolves inherent salts, the most abundant of those salts is usually what's known as 'free lime' which is left surplus from the matrix of the concrete. Removing efflorescence is difficult and labour intensive, and requires acid based remover. Many products attempt to mask the word 'acid' with "water based" and other jargon, and will often mask any unpleasant odour with a nice scent such as lemon. Regardless, an acid pH is essentially what's required to dissolve the efflorescence. Once efflorescence is cleaned, it is most likely going to return....

Efflorescence in the UK
Read more →Efflorescence is clearly a problem the world over. Google has images and stories about efflorescence from all four corners of the globe. During a visit to the UK, we have seen efflorescence leaching from the face brickwork of many new buildings and brick fences. Common perception from most local tradesmen is that efflorescence comes from modern clay bricks. In some walls we have seen, the bricks do appear to produce salts which are seldom seen in Australia. However, for the most part, it does appear that porous mortar is the main culprit, or sometimes there is a combination of leaching from both...

North Ryde train station stairs closed due to efflorescence.
Read more →The Epping to Chatswood railway line was opened in 2009 at a cost of $2.3 billion. It appears that only four years later, the stairs adjacent to the escalators are no-longer useable due to efflorescence, and are barricaded off. Estimated demolition/ replacement cost of stairs: $110,000.00 Estimated cost of Efflock for the entire twin flight of 75 steps: $320.00 As you can see, Efflock provides very economical protection. The water based formula is a green choice as it is a high concentrate, meaning less plastic waste. But best of all, Efflock ensures the intended service life of carbon hungry building...

All 3 bases are covered with Efflock
Read more →The genius of Efflock is that it is compatible with all cementitious mixes, including off the shelf tile adhesives and tile grouts. On a tiled floor, this means that all 3 layers that contribute to efflorescence can be protected - tile bed, tile adhesive and tile grout. And, it couldn't be easier. Simply add 1 part Efflock to 50 parts of water to use in all of your mixes for absolute confidence. No secondary membrane required! Above: Efflorescence appearing through porous grout joints.

Did you know? Efflorescence can be a liable defect.
Read more →Builders and tilers beware.In the past leaching or efflorescence was regarded as a 'maintenance issue' for building owners. However, since 2007 it has been listed as a defect in the national publication: 'Guide to Standards and Tolerances'. At the bottom of page 49 of the guide, is the following clause: "13.08 Calcification and efflorescence associated with decks and balconies Calcification or efflorescence caused by water coming from a deck or balcony that occurs on walls below or beside the deck or balcony; or that appears in the mortar joints of the deck or balcony tiling, is a defect. Activities of others,...

Efflorescence on ABC1's Gardening Australia:
Read more →Efflorescence is such a common building defect around Sydney and Australia. Did anyone else see Gardening Australia last night? Above: Check out the efflorescence coming up out of the grout joints from the tile bed on these balconies just next to Costa Georgiadis as he reported from an apartment complex in Redfern, Sydney. There was a fair bit of efflorescence seeping from render as well during the story. Using Efflock is the very best prevention for efflorescence. So simple and very economical.

Efflock testing: Boral Material Technical Services
Read more →Photo showing Efflock testing samples in the first week of testing (very slight efflorescence is visible on the control samples without Efflock on the left). Efflock is currently undergoing independent testing at the Boral Laboratory in Baulkham Hills, Sydney. This test facility is the largest of it's type in the Southern Hemisphere and is well recognised. Efflorescence testing can take a little while to manifest, but I've just had word from the Senior Development Engineer, Tony Song, that they are beginning to observe more conclusive results, and Efflock does perform. As part of the testing, we have created...
