  Efflock is now available in 5 litres

  We have now launched a 5 litre container of Efflock. 5 litres makes up to 505 litres of gauging water to prevent efflorescence and repel damp in all cement based materials. Ideal for larger jobs such as balconies, and for professional tilers requiring larger quantities. Please see our 'Where to Buy' page or click the 'Buy Online' if we don't yet have a stockist near you, and we can send it out.

  Efflorescence can be avoided

  Before Efflock, methods to control efflorescence required much complexity and have been flawed in one way or another. In fact, Chapter 9 of 2009 edition of the "Master Builders Association Guide to External Waterproofing" lists the the well adopted methods and highlights each of their disadvantages. In summation it concludes "there really is no way to completely prevent efflorescence"- which is incorrect. Efflorescence is something that is not widely thought about, until it begins to deface a building and starts costing money. It has until very recently been considered a maintenance issue, but that is no longer the case. Builders and tilers are being held liable,...

  Mould in shower grout

  Hate cleaning? Using Efflock in tile grout is an easy way to reduce mould.  Modern cement based tile grouts claim to have mould inhibitors in their formula, but still remain porous, failing to prevent ingrained mould for very long. Efflock however, can make a dramatic difference.  We made two test blobs of grout about 20mm thick. One was a control sample with plain water, and the other used 1 part Efflock to 100 parts water. Once the grout had cured and dried out, we submerged the grout samples into a 10 litre bucket of water. Both were broken in half using a...

  Trapping moisture with a secondary membrane

  The popular approach to controlling efflorescence on tiled balconies, is to provide a secondary membrane directly beneath the tiles. Another approach is to bond the tile bed directly to the substrate and install a single membrane on top. Both of these methods are popular and can be effective in controlling efflorescence from the tile bed, but there are pit-falls. Firstly, efflorescence is also known to release from tile adhesive and grout, which are both located above the membrane. Secondly, these methods trap all the moisture in the tile bed under an impervious membrane. Moisture in the tile bed concrete mix...
