Efflorescence Removal & Prevention
Facades of buildings, cementitious surfaces, bricks and stones are highly susceptible to efflorescence.
The influence of humidity, temperature, moisture, or (even worse) seawater results in the salt formation on surfaces visibly degrading the aesthetic appearance and permanently damaging the structure.
So how can you not only remove efflorescence that is so commonly seen on buildings around Australia, but also prevent it from happening again?
The Solution | Enviro DeSalin C & Enviro SurfaPore C
Enviro DeSalin C is a special cleaner based on a concentrated, natural acid. It is an effective formulation for removing residues and salt deposits created due to efflorescence and hard water build-up while mould and mildew can also be successfully removed. It is ideal for cleaning cementitious surfaces, mortar, grout, stucco, natural and artificial stones. The ingredients found in Enviro DeSalin C have the ability of complexing some of the key cations that produce salts, changing their chemical composition and removing them from building surface.
Enviro SurfaPore C is a water-based formulation, specifically designed to harness the power of nanotechnology to provide water repellency and protection to a wide range of porous surfaces. As its viscosity is similar to that of water, it deeply penetrates into the pores and capillaries that typical elastomer or polymer formulations cannot reach. Enviro SurfaPore C protects surfaces against the typical problems related to water and moisture, such as mould growth and efflorescence, and acts completely differently when compared to any two-component (2K) or silicone/silane/siloxane based formulations, as they do not create a “plastic film” on the applied surface.
As nanoparticles do not form polymer chains, SurfaPore modified surfaces can last longer; even after ten years they exhibit 95% of their original activity or functionality. Enviro SurfaPore modified surfaces are more resistant to the “hard” part of solar light (UV radiation) which does not induce the “yellowing” effect. Additional to this, the most important advantage of the SurfaPore technology is the high breathability of the modified surfaces.
In the case of rising damp or water leakage behind an Enviro SurfaPore C modified surface – the water can be evaporated back into the environment, without accumulating inside the building surface. The internal pressure developed is relieved by evaporation resulting in no swelling or cracking due to the trapped moisture while at the same time water is also blocked from being transferred inside the material.
All in all, Enviro SurfaPore C modified surfaces remain dry and unchanged in both appearance and mechanical properties.
To Remove Efflorescence: Rinse the stained surface with DeSalin C without diluting or up to 1:5 dilution ratio for slightly stained surfaces. Wait for DeSalin C to act on the surface for 10 minutes. Remove residues by scrubbing with a hard sponge (do not use metallic sponges). After removal, wash with plenty of water.
To Prevent Efflorescence: Let the surface dry and apply Enviro SurfaPore C by using a brush, roller or spraying. No dilution is required. On very absorptive surfaces reapply within 3 hours.
