Keeping water out prevents efflorescence - a guide to caulked movement joints
Read more →Efflock prevents efflorescence by repelling water as illustrated in this triangular diagram: Every detail in a system is important. Caulked movement joints may seem an insignificant detail, but if they are installed incorrectly excessive water can enter masonry to cause efflorescence. Below is an information sheet which explains how to install caulked movement joints correctly, with some information on selecting the best sealant for the job:

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....

DesignEx Sydney - Tile and Stone Seminar
Read more →Last week saw DesignEx at the Sydney Exhibition Centre - not the bulldozed one, but the temporary building at Glebe Island. Within DesignEx was the tile and stone seminar, where there were 3 days of many different speakers. Each were experts in different facets of the tile and stone industry. All of the topics were incredibly interesting, from the scientific structure of bluestone (basalt), to the evolution and latest trends in tiling and installation. Efflorescence was a hot topic touched on by almost every speaker, but there is also a new problem emerging known as latex leaching, introduced to us...

Grand Designs: Kevin McCloud revisits a house with efflorescence
Read more →Grand Designs often follows incredibly interesting building projects. A story following a house built in the Kent countryside in 2008 was no exception. The architect and owner constructed an experimental, unreinforced, terracotta arched building supporting an earth roof with tiles manufactured from clay onsite. The building was risky but has proved a great success and extremely energy efficient, even providing an income for the owners! Unfortunately two years later during Kevin's revisit, efflorescence has left it's mark: Kevins face says it.....should have used Efflock! ....Of course Efflock didn't even exist at the time this house was built, but perhaps...

200 litres of Efflock for New Development
Read more →One of our selected stockists, Euro Abrasives in St Peters, has supplied 200 litres of Efflock to Casumo Constructions for a new multi storey residential complex in Mascot, near Sydney Airport. 'The Tempo' is a new residential complex in Botany Road, due for completion later this year. Efflorescence and water problems have caused major headaches in apartment buildings, as the current design trends feature rendered walls, planter boxes, and tiled balconies. Project manager for Casumo Constructions, Joe Metlage, enquired about Efflock late last month. "Like many builders, we've experienced problems with efflorescence in the past, and we are excited that...

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...
