Grout can have a significant influence on both the appearance and long-term performance of a tiled finish. It should therefore be considered an integral part of the specification from the outset, not an afterthought.
The right product needs to complement the tile aesthetically, while also providing the durability and resistance required for its environment.
Beyond the finish
Grout products have evolved over the years to incorporate qualities such as stain resistance.
For example, the PURE CLEAN anti-stain technology within Saint-Gobain Weber’s weberjoint premium provides improved resistance to staining and discolouration. This is particularly valuable in areas where spills and staining are inevitable, including kitchens and bathrooms.
Such technology also highlights an important point: grout has to work with the tile, not simply sit alongside it.
Given the increasingly varied tile finishes and delicate glazes, a little due diligence before installation can prevent problems later.
A simple test can help establish whether a grout is compatible with the tile and whether its application could affect the surface finish.
Before committing to the full installation, test the grout on a spare tile or inconspicuous area to check compatibility and identify any potential adverse effect on the surface finish. This is especially relevant when working with softer or more delicate glazed tiles.
A good match matters
Compatibility shouldn’t stop with the grout, and selection should form part of a system-based approach. The adhesive and sealant also need to be selected with the tile type, substrate and intended environment in mind.
Considering products such as Weber’s tile adhesives, weberjoint premium grout and complementary sealants as part of a complete system helps ensure each component is suited to the application.
Perfection to the edge
The same principle applies to the perimeter; once the tiles and grout are installed, perimeter joints are another potential weak point if the wrong sealant is selected.
A good perimeter sealant should provide a durable, flexible finish while helping to protect vulnerable areas from moisture and mould. Choosing a mould-resistant product can therefore be an important part of achieving a finish that continues to look good long after installation.
Ultimately, the grout and sealant may be among the last products applied, but they should be two of the first things considered.
After all, the finishing touches are what define the appearance of a tiled surface.
