UltraTech Tilefixo Grout CG
A polymer-modified, white cement-based grout for 6 mm tile and stone joints, formulated for nil shrinkage and low water absorption.
What is it?
A single-component, white cement-based joint-filling grout for tiles, marble, granite and natural stone, modified with polymer additives and fine fillers, supplied as a powder mixed on site with water.
Where is it used?
Tile, marble and granite floor and wall joints in homes, offices and retail spaces; natural-stone facade joints; and re-grouting of tiled surfaces during renovation, wherever the joint stays within 6 x 6 mm.
Why use it?
Site-mixed white cement and sand grout shrinks as it dries and cracks at the joint edge within months, letting water track behind the tiles. The polymer in Tilefixo Grout CG cuts that shrinkage, lowers water absorption, and gives a tighter, more even-coloured joint than a hand-batched mix usually manages.
How is it applied?
Mixed with 27-29% water by weight for 2-3 minutes until lump-free, then pressed into clean, dust-free joints with a rubber float within the one-hour pot life, and wiped with a damp sponge once the joint has firmed.
About UltraTech Tilefixo Grout CG
UltraTech Tilefixo Grout CG is the everyday product in UltraTech’s Tilefixo range — what a site reaches for once tiling is done and joints need filling, rather than anything load-bearing or chemically exposed. It’s a white cement base carrying polymer additives and selected fillers, sold as a single-component powder in 1 kg pouches that a mason mixes with water at the point of use. The polymer separates it from plain white cement and sand mixed on site: it lowers shrinkage, improves adhesion to the tile edge, and keeps the cured joint’s water absorption down — a porous joint is exactly where staining and mould start in wet areas. It suits joints up to 6 x 6 mm, covering most ceramic, vitrified, marble and granite work; where joints run wider or the area sees heavy chemical exposure, epoxy grout is the right call instead.
The technical insight
The data sheet numbers say a lot about what this grout is for. Compressive strength of 5-6 MPa and flexural strength of 2-3 MPa at 28 days are modest by structural standards, but a tile joint carries almost no load — it needs to resist abrasion, movement and water, not compression. The 0.2 mm water absorption figure (Karsten tube, 24 hours) matters more for a bathroom floor: it measures how much moisture the cured joint pulls in by capillary action, and a low figure is what keeps grout lines from darkening or growing mould. Bulk density of 1450-1550 kg/m³ and the 27-29% water-powder ratio exist mainly for batching consistency — get the water wrong and both pot life and cured strength shift. The one-hour pot life at 27°C is a real constraint on a hot site: mix only what one mason can place in that window, since re-tempering a stiffening batch is against the manufacturer’s instructions and shows up later as patchy colour.
Where it is used
- Floor and wall tile joints in residential bathrooms, kitchens and balconies
- Marble and granite joint filling in lobbies and commercial interiors
- Natural-stone cladding joints on facades
- Vitrified and ceramic tile flooring in apartments, offices and retail units
- Tiled corridors and common areas in group housing
- Re-grouting of existing tiled surfaces during renovation
Key advantages
- Nil shrinkage versus a site-mixed cement-sand grout, so joints stay intact instead of hairline-cracking within months
- Low water absorption (0.2 mm, Karsten tube) keeps joints from darkening or growing mould in wet areas
- No water curing required, which shortens the handover timeline
- Consistent colour and a smooth finish batch to batch
- Single-component mix — just add water, no hardener or resin to measure
Limitations & considerations
- Rated only up to 6 x 6 mm joints — wider joints need an epoxy or wide-joint grout instead
- One-hour pot life at 27°C leaves little room for slow application in hot weather
- More porous and stain-prone over time than epoxy grout, so not the first choice for commercial kitchens
- Not intended for continuously submerged conditions such as swimming pools
Selection & best practice
Keep joints clean, dust-free and of even depth before grouting — residue left behind shows through as a dull patch once cured. Mix only what one applicator can place inside the one-hour pot life; on a hot Delhi NCR afternoon that window shortens, so smaller batches beat one large batch that starts stiffening halfway through. Press the grout in diagonally to fully pack the joint, and hold off on the final sponge-and-polish until it has firmed enough that wiping doesn’t pull grout back out. Let the floor cure at least 24 hours before foot traffic and about 3 days before standing water, and store pouches off the floor in a dry space.

Industry use cases
Residential
Bathroom and kitchen tiling, balcony flooring, and full-flat re-tiling jobs across Delhi NCR, where tight budgets favour a straightforward cementitious grout over epoxy.
Commercial interiors
Lobby and corridor marble or granite joints in offices and retail stores, where a tight, non-shrinking joint line matters more than chemical resistance.
Institutional / group housing
Common-area and staircase tiling in apartment complexes, where consistent colour across a long joint run reduces callbacks.
Renovation and repair
Re-grouting cracked or discoloured joints in existing floors, small-batch work suited to the 1 kg pack.

How we position UltraTech Tilefixo Grout CG
Within Space Arc’s tile-fixing range, Tilefixo Grout CG is the standard, budget-conscious option for routine tile and stone joint work up to 6 mm — what most residential and light-commercial jobs in Delhi NCR actually call for. It sits below UltraTech’s own epoxy grout line, the right step-up for kitchens or any floor needing real chemical or stain resistance; treat the 6 mm joint limit as the practical line between the two.
