  How to remove efflorescence

  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

  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.

  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

  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.

  Efflock testing: Boral Material Technical Services

       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...

  Australian Master Tilers Association

   Efflock is proud to be a member of the newly established, Australian Master Tilers Association. The Association was created last year to benefit the tiling and waterproofing industries and their customers (see their 'About Us' page). The AMTA Forum is an excellent platform for exchanging problems, ideas and advice, and is open for participation both from trade professionals and the general public.

  Efflock is the preferred choice for protecting million dollar views

     Even the most exclusive suburbs of Sydney with some of the most impressive private homes do not escape the scourge of efflorescence. Efflock is fast becoming the product of choice for remedial builders and tilers to rectify and prevent unsightly efflorescence stains from occurring.  Check out our 'Stockists' page or speak to your local trade supplier about stocking Efflock for your next project. Efflock is also available online with prompt free delivery throughout Australia.

  Some basic facts about everyday building materials you may not know.

  It was pointed out to me yesterday, that to date, my blogs are written in a way that assumes some prior technical knowledge about building. Considerable interest about Efflock is coming from home owners, 'Do-It-Yourselfers', or from people who are interested in including Efflock in their building project, but aren't quite sure how to recommend its use or exactly what it does to the tradesmen they are engaging. So here goes.... Firstly, many people may assume that concrete is waterproof: It makes sense right? You see concrete on bridges, footpaths, driveways and balconies everywhere, so surely water doesn't affect it?? ...

  What does Efflock cost per square metre of tiling?

  Efflock prevents efflorescence and creates hydrophobic tile bed, adhesive and grout for around $3.87/m2 (for a 30mm thick tile bed). Compare that with the cost of a secondary membrane for at least $20/m2, and you're way in front Even with a tile bed 100mm thick you're saving cost and extra processes. Plus there are no hassles with inclement weather, no issues with trapping moisture between two membranes, and you even have the option to wet bed your tiles! Efflock allows the bed to permeate, meaning it will release moisture from the hydration process, whilst repelling water ingress.  Less cost, big time savings...
