Epoxy grout is the gold standard for stain resistance, chemical durability, and hygiene. Unlike cementitious grout, it does not absorb water, making it ideal for swimming pools, commercial kitchens, hospitals, and luxury bathrooms. However, its rapid curing time and thorough cleaning requirements demand precision.
This guide covers both VFixer Epoxy Grout 2-Part (gel-based, normal & sparkle) and 3-Part (resin-based) systems, with field-tested techniques to ensure flawless results.
2-Part vs 3-Part Epoxy Grout
2-Part Gel Based
- Part-A (Resin) + Part-B (Hardener)
- Pack sizes: 1 kg & 5 kg
- Stain-free, color-fast, water cleanable when fresh
- Best for: Walls, floors, wet areas, pools, sterile rooms
3-Part Resin Based
- Part-A + Part-B + Part-C (Filler)
- Pack sizes: 1 kg & 5 kg
- Anti-bacterial, anti-fungal, chemical resistant
- Best for: Kitchens, hospitals, operation theaters, high-traffic floors
Tools Required
Step-by-Step Application
Surface Preparation
Ensure joints are clean, dry, and free of debris. Joint depth must be greater than 3 mm. Remove any loose mortar or spacers. Mask adjacent surfaces with painter's tape to protect from staining.
Mixing
For 2-part gel-based grout: mix Part-A (resin) and Part-B (hardener) in the exact ratio. For 3-part resin-based grout: add Part-C (filler) gradually. Mix until a uniform, lump-free paste is achieved. Do not mix more than you can use within 45 minutes.
Application
Work in small sections (approx. 1 m²). Use a hard rubber grout float held at a 45° angle to force epoxy deeply into joints. Ensure complete filling without air pockets. Move diagonally across tiles to minimize pulling grout out.
Initial Cleaning
Wait until grout is moldable and does not lift out of joints (typically 30–60 minutes). Using a white scrubby pad and plenty of clean water, lightly scrub tiles in circular motions to loosen residue. Change water frequently.
Final Wash
Approximately 2 hours after installation, perform a final wash with a mixture of water and mild vinegar solution (or manufacturer-recommended cleaner). Polish with a dry microfiber cloth for a crystal-clear, stain-free finish.

Cleaning & Curing Timeline
| Phase | Time | Action |
|---|---|---|
| Application Window | 0 – 45 min | Spread and pack into joints before mix stiffens. |
| Initial Set | 30 – 60 min | Begin first wash with scrubby pad and water. |
| Final Wash | ~2 hours | Use vinegar-water solution; polish with microfiber. |
| Light Traffic | 24 hours | Floor can accept light foot traffic. |
| Full Cure | 7 days | Achieves full chemical & stain resistance. |
Common Mistakes to Avoid
Mixing too large a batch
Epoxy cures fast. Mix only what you can spread and clean within 30–45 minutes. On hot days, reduce batch size by half.
Waiting too long to clean
Once epoxy cures on the tile face, it is extremely difficult to remove without mechanical abrasion. Clean in two stages: initial and final.
Insufficient joint depth
Joints must be at least 3 mm deep. Shallow joints result in weak grout that cracks under load.
Ignoring temperature
Application below 10°C slows curing; above 35°C accelerates it dangerously. Always check ambient and surface temperature.
Frequently Asked Questions
- Is epoxy grout waterproof?
- Yes. VFixer Epoxy Grout is waterproof and does not absorb liquids, making it ideal for swimming pools, showers, and chemical resistance areas. Water absorption is classified as Nil (1).
- Can epoxy grout be used outdoors?
- Absolutely. It withstands UV exposure, freeze-thaw cycles, and thermal shock. It is rated for both dry and wet areas, including hydrotherapy pools.
- Why is my epoxy grout cloudy after cleaning?
- Cloudiness usually results from hard water residue or incomplete rinsing. Perform a final wash with clean water and a microfiber cloth. For stubborn haze, use a mild vinegar solution.
- Do I need special tools to remove cured epoxy haze?
- Prevention is better than cure. If haze has cured, use a non-abrasive white scrubby pad with warm water. Avoid steel wool or acidic chemicals on polished tiles.
