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...
Where to use Efflock
EFFLOCK is an revolutionary product to redefine the way we build.
Efflock is an advanced concrete additive to repel damp and lock efflorescence. It dilutes 100 times with water to mix with most types of cement-based building materials. Efflock's universal compatibility protects tile beds, tile adhesives, tile grout, brick mortar, render and concrete.
Efflock provides permanent hydrophobic, bulk impregnation of the entire concrete mass that is not compromised by cracking from building movement or traffic wear. Water is controlled to prevent the migration of calcium hydroxide and other salts to cause efflorescence. To date, no other approach is as reliable or effective.
The hydrophobic effect is a huge advantage when tiling wet areas such as bathrooms and balconies. Mould is dramatically reduced, and the Efflock impregnated materials form an additional barrier against waterproofing failure and capillary action. Waterproofing membranes become less vulnerable to failure.
In bricklaying, stone masonry and render, Efflock will prevent rising damp and salt attack. Efflock provides an effective damp proof course within the mortar, and keeps off-white mortar clean by repelling water that carries dirt and feeds algae.
Efflock can even be used as a sealer! View more details in our Technical Data Sheet (996KB pdf)
