Tile Grout Efflorescence – Removal and how to prevent reoccurrence

 

Waterstop Solutions recently tended to some tiled patios and balconies of an apartment building identified by the client as experiencing efflorescence along the tile grout lines.

Efflorescence is a common tile, stone, concrete, brick and grout problem. In this case, the efflorescence is caused by water soaking through the tile grout under the tiles and then evaporating to the surface.

Soluble salts and minerals that are present in the concrete are drawn up from the tile bed through the grout by capillary action. When the carrier moisture evaporates the salts and minerals crystallise and create a build-up of efflorescence (lime/calcium deposits) that appears as white coloured staining on the grout lines and tiles.

To remediate this, we recommend installing a penetrating waterproofing repellent (PWR).

After cleaning the tile grout efflorescence with a vinegar solution our technicians dried the substrate with heat and fans for best product performance. Once the substrate was dry, they installed a penetrating waterproofing repellent (PWR) to the tile grouts to reduce the water tracking under the tiles.

Waterstop Solutions’ PWR can be used on any porous substrate without changing its appearance, to maintain a dry look and offering minimal to no visual change to the substrate.

This PWR system penetrates into the substrate reducing the pore size so that liquid can no longer pass through the substrate, while still allowing it to breathe. This can create a water beading “off a duck’s back effect. The PWR system will also ease the cleaning of the treated area and reduce mould growth and dirt pick up. This treatment does need to be reapplied for best results, typically every 5-10 years, depending on application.

  2. Brickwork, masonry blocks
  3. Tiles
  4. Some natural stones
  5. Traditional and modern stucco and render
  6. Traffic bearing surfaces

 

 

5 Benefits you can expect with PWR Sealant

  1. Long-lasting BARRIER against SALT, MOISTURE and CHEMICAL attacks
  2. Great CURB APPEAL and SALE VALUE with New-Look preservation
  3. Invisible, dry and natural look finish
  4. Protection against damage caused by moisture intrusion (corrosion, concrete cancer, efflorescence, leaching, scaling and spalling)
  5. No more scrubbing or power washing! The PWR sealant decreases dirt adhesion and prevents moss and mould growth. (Rainfall or a light garden hose wash is enough)
