Double Charged Tiles: How They Work and Where to Use Them

Most floor tiles keep their design in a layer thinner than a coin. That is fine in a bedroom. It is not fine under a car that turns its wheels on the same spot twice a day, or on a terrace that takes sand, grit and monsoon water for years. Double charged tiles exist for exactly those floors: the colour and pattern go a few millimetres into the tile, so when the surface wears, the design underneath is still the same design.

This guide explains what double charging actually is, how it compares with glazed vitrified (GVT), polished glazed vitrified (PGVT) and full body tiles, and where each is the right buy, based on what we stock at our BTM Layout showroom.

Our range is 41 double charged tile designs, all vitrified, all matt, and all for floors. All but one are sold for parking, balconies and terraces. If you want glossy double charged tiles for a living room, skip to what we don't carry.

What double charged tiles are

The name comes from the press. In a normal vitrified tile, the body is pressed from one fill of powder and the design is applied on top, usually as a digitally printed glaze. In a double charged tile, the press is fed twice. A first charge of plain body powder goes into the mould, then a second charge of pigmented powder is laid over it in the pattern, and the two are pressed together into one piece before firing.

After firing at high temperature the whole thing fuses into a dense, low-absorption body, which is what vitrification means. The pigmented top layer, a few millimetres thick, is part of the tile, not a coating on it. Scratch the surface and you find more of the same colour.

The trade-off is design. Because the pattern is laid as coloured powder rather than printed, double charged designs tend to be speckled, granular, geometric or softly mottled. You will not get photographic marble veining or a convincing wood grain the way you would from a digital glazed tile.

Double charged tiles vs GVT, PGVT and full body

Shops use these names loosely. What matters is where the design lives and what happens when the top wears.

Put simply: GVT and PGVT win on looks, full body wins on pure toughness, and double charged sits in between. It gives you more design than a full body tile and far more wear depth than a glazed one. The vitrified vs ceramic tiles guide covers the body underneath all four, and porcelain tile gives the background on dense bodies.

What our double charged tile range looks like

Prices are per sq ft. Where a group is only partly priced, the figure covers the priced designs only.

That adds up to 22 parking designs, 18 balcony and terrace designs and one bathroom design. Twenty of the 41 are on display at the showroom, and twenty carry a listed price between ₹67 and ₹95 per sq ft. The rest are quoted on request. Geometric patterns dominate, at 29 of the 41, because small repeating shapes hide tyre marks and dust better than a plain shade.

Sizes and finish

Two sizes cover almost everything. 21 designs come in 400x400 mm and 17 in 500x500 mm. Both are small on purpose: a parking floor slopes towards a drain and takes point loads from tyres and jacks, and small tiles follow the slope and spread the load where a large slab would rock or crack over a hollow.

All 41 are matt. We do not carry a glossy double charged tile, and for outdoor floors we would not sell you one if we did. Polished tile on a sloped driveway in Bengaluru's monsoon is a slip waiting to happen. Our matt vs glossy tiles guide goes through where each finish belongs.

Where double charged tiles make sense

Car parking and driveways

This is the job the tile is built for, and 22 of our designs are sold for it. A car's tyres twist on the tile every time you turn into the slot, and that twisting can grind the print off a glazed tile over the years. A double charged surface wears too, but it wears into more of the same colour. Our tiles design for parking guide has layout ideas, and the full parking floor tiles range includes the non double charged options too.

Terraces and open balconies

An open terrace takes strong sun, sand blown in from the road, chairs dragged across it and a full southwest monsoon every year. The 18 balcony and terrace designs include our wooden and Moroccan double charged patterns, which are the closest this category gets to a decorative look. Browse the geometric balcony and terrace tiles to see the bulk of them, and our balcony tiles design guide for how they work in a small space.

Where to look elsewhere

If you want a glossy double charged tile for a living room or a large-format 800x800 or 600x1200 mm double charged floor, we don't stock one. For dry indoor rooms, a good GVT or PGVT will look better and wear well enough under normal household use,. Our floor tiles price guide covers indoor options by room.

Bathrooms are the other place to be careful. We have exactly one double charged design sold for bathroom floors. A bathroom needs grip more than wear depth, so start with the anti-skid bathroom tiles guide instead.

What they cost and what pushes the bill up

On the designs we list prices for, double charged tiles run ₹67 to ₹95 per sq ft. Within that band the CA-series plain and geometric designs sit at the bottom at ₹67, most of the X-series 400x400 mm designs are at ₹81, and most of the 500x500 mm Moroccan, wooden and geometric designs sit at ₹95. In our range, the bigger size tends to cost more.

On an outdoor floor, also budget for:

• Wastage. Columns, drains and ramps mean more cutting waste than a rectangular room. Our guide to working out how many tiles you need shows the box maths.
• Slope and bed preparation. The base has to fall towards the drain before a single tile goes down.
• Adhesive over sand-cement. For vehicle areas, a proper tile adhesive gives a fuller bed under each tile, which is what stops tiles cracking under tyres.
• Grout. Outdoors, a cement grout in a mid grey or brown hides dirt. Light grout in a parking bay goes dark fast.

Laying and care for Bengaluru conditions

Beyond the tile itself, three things decide how long a double charged floor lasts.

1. Drainage. Standing water grows algae and stains the floor. Check the fall towards the drain with water before the tiles go down.
2. Movement joints. Large outdoor areas expand in strong sun and contract in the rain. Leave joints at the edges and across big spans, or tiles can lift.
3. Cleaning. Sweep often: grit under shoes and tyres does the wearing. Avoid regular acid cleaning for hard water marks: it attacks the grout long before the tile.

Twenty of our double charged designs are laid out at the BTM Layout showroom. Bring a photo of your parking or terrace and the rough area in sq ft, and we will pull the four or five that suit the slope, the light and your budget, and lay them side by side so you can see how the pattern repeats.

Frequently asked questions

What are double charged tiles?

Double charged tiles are vitrified tiles pressed from two fills of powder. A plain body layer goes in first, then a pigmented layer carrying the design is laid on top, and both are pressed and fired together. The result is a design that runs a few millimetres into the tile instead of sitting in a thin printed glaze, so it survives heavy wear.

Are double charged tiles better than GVT tiles?

They are better for wear, not for looks. A double charged tile keeps its design when the surface is abraded, which suits parking and terraces. A GVT tile has a digitally printed glaze, so it can show marble, wood or stone far more convincingly. For dry indoor rooms GVT is usually the better buy, and for vehicle areas double charged is.

What is the difference between double charged and full body tiles?

In a full body tile the colour runs through the entire thickness, so even a chip looks the same. In a double charged tile only the top few millimetres carry the colour and pattern, with a plain body below. Full body is tougher in theory, but double charged gives more design choice and is plenty for a home parking area.

Which double charged tiles are best for car parking?

Choose a matt, patterned design in a small format such as 400x400 mm. The small size follows the drainage slope and spreads tyre load across more joints, and a geometric pattern hides tyre marks and dust better than a plain shade. Lay it on a full adhesive bed over a properly sloped base so the tiles do not crack.

What is the price of double charged tiles in Bangalore?

At our BTM Layout showroom, the double charged designs with a listed price run from ₹67 to ₹95 per sq ft. Plain and simple geometric designs sit at the lower end, and most of the 500x500 mm Moroccan, wooden and geometric designs sit at the top. About half of our 41 designs are quoted on request, so ask for a figure on those.

Can double charged tiles be used in a living room?

They can, and polished double charged tiles are made for indoor floors, but we do not stock them. All 41 of our double charged designs are matt and sold for parking, balconies, terraces and one bathroom design. For a living room we would suggest a glazed vitrified tile instead, which offers far more design choice and wears well enough indoors.

Are double charged tiles slippery when wet?

A polished double charged tile can be slippery when wet, which is why it should stay indoors. Every double charged tile we carry is matt, which gives better grip on rain-soaked terraces and sloped driveways. Grip still depends on keeping the floor clean, since wet algae or mud on any tile surface is slippery, so good drainage matters as much as the finish.
