Upgrading modern construction with the power cementitious grouting

“Intriguingly, epoxy grouts, formulated with epoxy resin, offer exceptional performance in high-traffic environments, making them the preferred choice for wet areas in residential buildings and heavy foot-trafficked zones in commercial structures.”

Modern construction relies on tiling for aesthetics and structural strength; while tile installation is crucial, grouting equally fortifies and enhances the appearance of surfaces. In this article, we delve into the intricacies of cementitious grouting, shedding light on its types, applications, and advantages.

Understanding Grouting

At its essence, grouting involves filling the gaps between tiles to bolster their strength and durability. This process not only contributes to the longevity of the tiled structure but also elevates its visual appeal. The grouting completes the tiling endeavour, bridging gaps and providing a seamless finish.

Exploring the Types of Grouts

Amidst the array of options available, selecting the right grout can be a daunting task. Grouts are broadly categorised into cementitious, epoxy, and PU grout.

Cementitious Grouts

Infused with polymer modifications, cementitious grouts offer a dependable solution for tile joints. They effectively fill gaps, level surfaces, and create durable, dust-free tile joints. This type of grout is suitable for various tiles, including natural stones, ceramics, and porcelain. Cementitious grouts are further classified into two types: unsanded and sanded grouts.

Unsanded Grout: Designed for narrower joints, unsanded grout is optimal for gaps within 1mm to 6mm. It is particularly effective in dry areas and is available in a diverse range of shades.

Sanded Grout: Ideal for wider joints exceeding 6mm, sanded grout’s coarse composition necessitates sealing to prevent staining. It finds utility in the terrace and podium areas, offering enhanced durability.

Epoxy Grout

Crafted from epoxy resin, filler powders, pigments, and hardeners, epoxy grouts excel in high-performance areas. They shine in residential and commercial settings with heavy foot traffic and are especially suitable for wet environments.

PU Grout

PU grout, a single-component resin-based filler, stands out for its versatility. It boasts attributes like colour uniformity, water repellence, flexibility, and stain resistance, rendering it suitable for various internal and external conditions.

Choosing the Right Grout

Selecting the ideal grout hinges on several factors, each impacting the outcome of your tiling project.

Purpose of Grouting: Depending on whether you’re prioritising aesthetics, durability, or hygiene, different grout types will suit your needs.

Colour Choice: Grout colour can complement or contrast your tiles, influencing the overall aesthetic effect.

Areas of Application: External conditions demand grouts with specific attributes like temperature resistance and durability.

Service Life Expectancy: The anticipated longevity of the grout plays a pivotal role, particularly in areas subjected to high mechanical stress.

· Versatility in temperature extremes

· Minimised risk of shrinkage cracks.

· Easy application and cleaning.

· Additional properties can be enhanced with liquid additives.

· Slower strength development compared to epoxy grouts.

· Vulnerability to water during mixing.

· Inferior mechanical properties compared to epoxy grouts.

Notwithstanding these drawbacks, cementitious grouts remain popular due to their cost-effectiveness, widespread availability, and diverse colour range. Their usability window of up to 60 minutes adds to their practicality.
