Powergrout GT2: The Ultimate Guide to a Flawless, Durable Tile Finish

For anyone who has ever invested in beautiful tiles—be it for a sleek kitchen backsplash, a sprawling commercial lobby, or a pristine industrial floor—the inevitable challenge has always been the same: protecting the investment. Traditional cement-based grouts, while functional, often become the weakest link. They stain, crack, harbour mould, and succumb to chemicals, turning a once-impeccable surface into a maintenance nightmare.

The construction industry demanded a revolution, a solution that was not just a filler but a permanent seal of protection. The answer arrived in the form of advanced epoxy grouts. And among these, one name has consistently set the benchmark for performance and reliability: Powergrout GT2.

This definitive guide will dive deep into Powergrout GT2, exploring what it is, why it’s a game-changer, and how you can use it to achieve a tile installation that doesn’t just look good on day one, but remains flawless for decades. We will cover its pros and cons, provide a detailed application guide, and clearly illustrate the Powergrout GT2 difference that sets it apart from every other product on the market.

What is Powergrout GT2? Redefining the Concept of Grout

what is the use of Powergrout GT2?

At its core, Powergrout GT2 is not a grout in the traditional sense. It is a high-performance, three-component (Resin, Hardener, and Filter Powder) epoxy grouting system. Unlike porous cement grouts, Powergrout GT2 forms a dense, non-porous, and homogenous solid mass upon curing.

Think of it this way: if conventional grout is like a sponge that absorbs everything it comes into contact with, Powergrout GT2 is like a sheet of glass—smooth, impermeable, and incredibly tough. This fundamental shift in material science is what unlocks a world of benefits, making Powergrout GT2 the preferred choice for architects, contractors, and discerning homeowners who refuse to compromise on quality.

The advanced formulation of Powergrout GT2 provides exceptional resistance to a wide range of chemicals, stains, and abrasions, ensuring that the grout lines remain as pristine as the tiles themselves.

Why to Use Powergrout GT2? The Compelling Advantages

Choosing your grout is as critical as choosing your tiles. The decision to use Powergrout GT2 is an investment in long-term performance and peace of mind. Here are the undeniable reasons why you should make the switch.

1. Unmatched Stain and Chemical Resistance

This is the flagship benefit of Powergrout GT2. Its non-porous nature means that common staining agents like coffee, wine, turmeric, oil, and grease simply cannot penetrate the surface. In industrial and commercial settings, it stands undeterred against acids, alkalis, and solvents, making cleanup a simple wipe-down affair.

2. Superior Strength and Durability

Powergrout GT2 exhibits exceptional compressive and flexural strength. It does not crumble or crack under heavy foot traffic or load, making it ideal for shopping malls, airports, factories, and driveways. It effectively locks tiles in place, contributing to the overall stability of the tiled surface.

3. Hygienic and Mould-Resistant

The absence of pores eliminates the damp, dark environment that mould and mildew need to thrive. This makes Powergrout GT2 the health-conscious choice for bathrooms, kitchens, hospitals, laboratories, and food processing plants, where hygiene is paramount.

4. Consistent Colour and Aesthetic Appeal

While cement grouts can fade, discolour, and develop patchy areas over time, the colour in Powergrout GT2 is consistent throughout the material. It retains its original shade indefinitely, ensuring your tiled surface looks brand new for years.

5. Low Maintenance and Easy Cleaning

The smooth, glass-like finish of Powergrout GT2 means dirt and grime have nothing to cling to. Regular sweeping and occasional mopping are all that’s required to maintain its like-new appearance, saving significant time and money on cleaning chemicals and labour.

When to Use Powergrout GT2: The Ideal Applications

Understanding when to use Powergrout GT2 is key to leveraging its full potential. It is the superior solution for virtually any demanding environment.

• Commercial Kitchens & Restaurants: Where grease, food acids, and heavy cleaning are daily realities.
• Food Processing & Pharmaceutical Plants: Where stringent hygiene standards and chemical resistance are non-negotiable.
• Swimming Pools & Wet Areas: Resistant to constant water immersion and pool chemicals without degrading.
• Industrial Flooring: For factories and warehouses exposed to oils, fuels, and industrial chemicals.
• High-Traffic Public Areas: Airports, shopping malls, and hospitals where durability and easy maintenance are critical.
• Residential Bathrooms & Kitchens: For homeowners who desire a premium, lifelong finish without the hassle of grout discolouration or mould.

How to Use Powergrout GT2: A Step-by-Step Application Guide

Proper application is crucial to achieving the legendary performance of Powergrout GT2. Unlike cement grout, it has a specific methodology. Here’s a detailed guide on how to use Powergrout GT2 correctly.

Pre-Application Checklist: Surface Preparation

1. Tile Fixing: Ensure tiles are firmly fixed using a high-quality adhesive like Gritolo’s Tile Adhesive. The adhesive must be fully cured before grouting.
2. Joint Cleaning: The tile joints must be clean, dry, and free from dust, loose material, grease, wax, or any other contaminants. A vacuum cleaner is highly recommended for this step.
3. Joint Depth: The joint depth should be at least 2/3rd of the tile thickness for optimal performance.
4. Temperature: Ambient and surface temperatures should be between 10°C and 35°C during application.

Mixing Procedure: Precision is Key

Powergrout GT2 comes in three components: Part A (Resin), Part B (Hardener), and Part C (Filter Powder).

1. Primary Mix: In a clean container, first mix the entire contents of Part A (Resin) and Part B (Hardener) together thoroughly for 2-3 minutes until you get a homogenous mixture.
2. Secondary Mix: Gradually add the entire contents of Part C (Filter Powder) to the mixed resin-hardener blend.
3. Final Mixing: Mix mechanically using a slow-speed drill (300-400 RPM) with a paddle mixer for 4-5 minutes. Scrape the sides and bottom of the bucket to ensure no dry powder remains. The final mixture should be smooth, lump-free, and of a uniform colour.
4. Slaking: Let the mixed grout stand (slake) for 5-7 minutes. This allows the chemicals to react and the powder to be fully wetted.
5. Final Stir: After slaking, give a final brief stir for about 1 minute. The Powergrout GT2 is now ready for application. Important: Do not add water or any other material to the mix.

Application Technique: Working Efficiently

1. Tool: Use a firm, non-absorbent rubber float or a dedicated epoxy grout float held at a 45-degree angle.
2. Applying Grout: Spread the mixed Powergrout GT2 forcefully across the tile surface, diagonally to the joints, ensuring all joints are completely packed and filled.
3. Initial Cleaning: After applying a manageable area (approx. 5-10 sq. m.), wait for about 15-20 minutes for the grout to initial set. Then, using a clean, damp (not wet) cellulose sponge, wipe the excess grout off the tile surface in a diagonal motion. Rinse the sponge frequently in a bucket of clean water.
4. Final Cleaning: After another 30-45 minutes, perform a second, finer cleaning with a clean, damp sponge and clean water to remove any remaining grout haze. For glossier tiles, a final polish with a soft, dry cloth once the surface is fully dry will enhance the shine.

Curing and Putting into Service

• Walk Time: Light foot traffic is typically possible after 12-16 hours.
• Full Cure: Powergrout GT2 achieves its full chemical and physical resistance properties in about 3-7 days, depending on temperature and humidity.
