  Elastomeric paints are a wise choice for efflorescence prevention

  Without damp or water penetration, efflorescence cannot occur. Efflorescence is caused by a concentration of salts that have been dissolved by moisture and transported by capillary action to a point of discharge where the moisture evaporates, and leaves the salts behind.  Water is the most destructive compound that works against the health and longevity of any building, in so many different ways other than just efflorescence. Therefore, a quality building specification must always pay careful attention to preventing the ingress of water and damp in every situation.  For over a decade, a cement rendered and painted finish has been very popular in Australia. Render has often been applied...

  Pool + Spa Review

  Efflock has featured on Pool + Spa Review's website this week. Please check out the article here. Efflock is ideal for use in render above the water line behind pool tiles. Its also excellent for use in tile screeds and grout in pool surrounds to prevent efflorescence, crypto-florescence and prevent salt attack caused by pool chemicals.  When paving with porous materials such a sandstone, bluestone, concrete or brick pavers, Efflock is excellent as both a pre-sealer and impregnating sealer to again prevent salt attack that can occur from crystallisation of pool chemicals.

  Keep face brickwork looking sharp with Efflock

  DIRTY BRICKS!!'Bowral Blue' face bricks cost $2.50 each or around $225.00 per square metre installed. Unfortunately, because mortar is ordinarily porous, it holds moisture and dirt - perfect for algae and moss to flourish. Just observe 1-2 year old buildings next time you're out driving to see what we mean. For only $3/m2 Efflock repels water, keeping mortar sharp, clean and efflorescence free.    For further protection, remember Efflock can also be used as a surface applied sealer to bricks! See our Product Data Sheet on our FAQs page for details!

  When salt attack hurts! - Scarborough Beach, Western Australia.

  Check out the photo of these concrete pavers. They are adjacent to the beach shower at Scarborough Beach in Perth. Pavers in the splash zone have been eroded from salt attack, presumably from swimmers rinsing sand and salt from the beach.  I was in Perth to visit local stores and to compete in the Australian Surf Lifesaving Titles, and I made the mistake of walking across these pavers in bare feet! The bits of gravel were particularly uncomfortable.  Efflock is ideal for concrete block and paving manufacturers. Efflock prevents salt attack, as well as efflorescence and algae growth. Best of...

  Salinity in Australia - a big problem that builders need to consider.

  The Master Builders Association meeting held in Maitland last week had a very entertaining and informative guest speaker from the NSW Department of Primary Industries. The topic was urban salinity. Salt from the soil can have a very destructive and catastrophic effect on masonry in buildings. Salt is drawn up into masonry with rising damp, and over many years with wet and dry cycles, more and more salt is deposited into the point of evaporation, typically in brickwork or stonework below damp proof course [DPC] level. The pressure exerted by crystallising salt can exceed 200MPa, whilst the tensile resistant strength...

  Rising Damp and Salt Attack - free PDF

  We have recommended this publication on our blog previously: Salt Attack and Rising Damp - A Guide to Salt Damp in Historic and Older Buildings. Salt attack is as destructive to masonry as termites are to timber, and is prone to occur on any building site in Australia due to our soils and extreme weather patterns. As salt is dissolved by water and absorbed by masonry, the water evaporates, leaving behind more and more salt with each wet cycle. Salt crystallises to expand at extraordinary pressure   (> 200MPa) to easily turn stone, bricks and mortar to dust. As outlined...

  Brick Mart now stocking Efflock

  Brick Mart in Brookvale (Northern Beaches in Sydney) are the latest building supplies store to carry Efflock. Brick Mart is a most impressive one stop shop for all bricklaying tools and supplies. Brick Mart carry everything from a full range of bricks, to scaffolding, tools, sand and cement. Efflock was recommended to Brick Mart by the boys at TMT Building, who are currently working together on a multi-unit development in Manly, on the Northern Beaches of Sydney. TMT Building was one of the first building companies to use Efflock, and now include Efflock in all their building specification from bathrooms...

  Efflock to present to Master Builders Association - Manly Warringah Division.

  Efflock will be a guest speaker at tomorrow night's meeting of Manly Warringah Division of the Master Builders Association. Click on the link for details and to book. All are welcome to attend and building professionals can collect 2 CPD points for attending.  Efflock also presented to the Southern Highlands Division of the MBA in Goulburn last night.

  Efflock ideal for building in high saline areas

  I gave a talk about Efflock to local builders at a Master Builders Association meeting out at Campbelltown last week. An interesting problem was raised, which I have touched on briefly in a previous blog.  A builder at the meeting told me that the soil in the Camden area south west of Sydney is notorious for high salinity. The high salt content presents major problems for standard construction where rising damp can have very damaging effects on brickwork below the DPC or 'Damp Proof Course' level. The DPC is typically located around floor level, meaning that numerous courses of bricks...
