Grout cracking is a common issue caused by movement between two surfaces. Homes naturally shift over time due to humidity, temperature changes, foundation settling, and other factors. If the grout used is rigid (like cement grout), it can crack when surfaces such as a bathtub and tiled walls move in different directions.

PPA Epoxy Grout is a high-performance grout made from epoxy resins, silica fillers, pigments, and a hardener. Unlike cement-based grout, it does not use Portland cement or water in its mixture. It is non-porous, waterproof, stain-resistant, and highly durable, making it ideal for high-moisture and high-traffic areas.

Cement grout is a traditional grout made from Portland cement, filler particles, and water-retention additives. While it is a cost-effective option, it is porous, which means it can absorb water and stains over time, leading to discolouration.

What is the main difference between PPA Epoxy Grout and cement grout?

PPA Epoxy Grout: Made from epoxy resins and fillers, it is highly durable, waterproof, and stain-resistant. It is non-porous, making it ideal for kitchens, bathrooms, and patios.

Cement Grout: Made from cementitious powder, it is cheaper but porous, prone to water absorption, and susceptible to staining and discolouration over time.

PPA Epoxy Grout offers many benefits:

• Waterproof and stain-resistant
• Highly durable and resistant to chemicals, abrasions, and cracking
• Non-porous, preventing mould, mildew, and bacteria growth
• Provides consistent colour and a strong bond
• It is perfect for areas exposed to water, grease, and harsh chemicals, such as bathrooms, kitchens, patios, schools, and commercial kitchens.

However, it can have a plastic-like finish that some homeowners may not prefer, and it requires more time and precision to apply compared to cement grout.

PPA Epoxy Grout: Use in areas exposed to moisture, heavy use, and chemicals, such as tiled floors, splashbacks, bathrooms, showers, patios, kitchens, and commercial spaces. It provides an additional layer of protection alongside waterproofing membranes.

Cement Grout: Use in low-moisture, low-traffic areas where budget is a concern.

Yes, PPA Epoxy Grout is completely waterproof due to its non-porous nature. It resists moisture and staining, making it the top choice for wet areas like bathrooms, kitchens, and patios.

Yes, you can apply epoxy grout over cement-based grout, but you must first remove the existing cement grout to at least halfway down the tile depth. Use tools like a scraper or grout saw to achieve this. For overhead applications, allow the epoxy grout mixture to stiffen slightly before applying to improve adhesion.
