Porcelain Tiles: Types, Benefits, Uses and How to Choose

The floor plan is now set and the budget is locked. Enter the step that no one tells you about – deciding on tiles. Inside the showroom, three different salesmen will all describe three distinct tiles as porcelain, the price of each of two identical tiles varies dramatically, and all of them insist that theirs is better. All you want is for any one of them to make it through Hyderabad’s rain.

So, What then are porcelain tiles? Porcelain tiles are ceramic tiles which are more dense than regular tiles, made from fine clay, feldspar, and silica through high-pressure and high-temperature processes. They have a water absorption rate of 0.5%, hence they are used on floors and walls of residential and commercial buildings.

Low absorption alone is not the end. The finish, size, non-slip properties, and even installation of the tile become equally important. This guide takes care of all this in simple terms, which means that you enter the showroom already knowing what questions to ask.

What Are Porcelain Tiles?

Porcelain is one of the ceramic family, simply the more compressed part. It is made using fine raw materials which have been pressed into place very firmly, and heated to the extent that the body vitrifies; here the particles soften and fuse together, and vitrified material has almost no pores. According to ISO 13006, tiles with water absorption of 0.5% or lower are in Group BIa. That’s where porcelain is.

The other thing that buyers get wrong: low absorption doesn’t mean a floor is waterproof. Water can still get through the grout lines and adhesive, so a bathroom, balcony and any other waterproofing layer is required underneath.

What Are Porcelain Tiles Made Of?

Mainly kaolin and other fine clays, feldspar and silica, plus pigments and additives. Recipes differ from one manufacturer to another.

Material	What it does
Kaolin and clay	Forms the ceramic body
Feldspar	Melts during firing and helps the body vitrify
Silica	Adds to the mineral structure and stability
Pigments	Decide colour and appearance
Other additives	Help with pressing, drying and finishing

How Are Porcelain Tiles Manufactured?

1.      Raw materials are weighed, ground and mixed into a slip.

2.      The slip is spray-dried to a fine powder.

3.      The powder is consolidated under pressure into tiles.

4.      The tiles are dried.

5.      Apply glaze and digital decoration to necessary areas of the tile.

6.      The tiles are fired until the body of the tile vitrifies.

7.      They are polished or finished and then graded by size, color and quality.

What Are the Different Types of Porcelain Tiles?

• Glazed: A printed surface layer. Provides the widest variety of patterns, but first verify the abrasion rating before using it in a highly trafficked floor.
• Unglazed: No surface layer, only body becomes the surface. Full-body may or may not apply to unglazed tiles.
• Full-body: The pattern penetrates throughout the tile, thus chips and scuffs become less visible. Suitable for use in stores and offices.
• Polished: A highly reflective surface giving extra brightness to the room. Reflects footmarks and tends to get slippery if wet.
• GVT and PGVT: Glazed vitrified tiles printed with digital patterns; PGVT means polished variant. First find out the usage rating for each particular product. All PGVTs aren’t necessarily wall tiles only.
• Large format slabs: fewer joints, but also heavier and require an experienced installer.

What Are the Different Porcelain Tile Finishes?

Finish	Best for	Keep in mind
Glossy or polished	Living rooms, lobbies	Slippery when wet; shows marks
Matte	Bedrooms, kitchens, bathrooms	Check the rated slip resistance
Satin	General interiors	Looks different from brand to brand
Textured	Balconies, wet areas	Dirt settles in the grooves

Stone, marble and wood looks come from printing, so you can find them in almost any finish. And remember, a finish name is not a slip rating. Ask for the tested value.

What Are the Advantages of Porcelain Tiles?

• Low water absorption properties, suitable for wet conditions provided installation is proper.
• Good wear resistance qualities, suitable for use in homes and commercial premises.
• Easily cleaned using a broom and a wet mop.
• Designs in very large varieties, ranging from marble and stones to wooden or concrete designs.

None of these makes the floor unbreakable or scratch-proof.

What Are the Disadvantages of Porcelain Tiles?

• More expensive tiles such as premium quality or large tiles cost higher, as does labor.
• It is difficult to cut and drill due to its denseness.
• Inadequate bonding on the substrate will result in cracking.
• Some tiles after polishing become slippery when wet.
• Tiles from another lot may be mismatched with respect to size or shade.

Porcelain Tiles vs Ceramic Tiles vs Vitrified Tiles

Porcelain is a denser, lower-absorption kind of ceramic tile, while “vitrified” is a broader trade term that often overlaps with it. They are not three separate materials.

Factor	Ceramic	Porcelain	Vitrified (trade usage)
Water absorption	Usually above 0.5%	0.5% or less	Usually low; verify
Density	Lower	Higher	Medium to high
Durability	Walls, light-traffic floors	Floors, walls, wet areas	Depends on type
Cutting and fixing	Easier	Needs good tools	Similar to porcelain

What should I use for my flooring? 

Porcelain or vitrified tiles, whose low absorbency and proper wear rating have been verified, should be used for flooring. Ceramic can be used in the case of wall surfaces and areas where little traffic occurs. Take into consideration only the data sheet.

Where Can Porcelain Tiles Be Used?

Area	What to look at
Living room	Looks and traffic; large formats and marble looks work well
Bedroom	Comfort; wood-look and matte are popular
Kitchen	Floor rating, grease cleaning, grout colour
Bathroom	Slip resistance and waterproofing
Balcony and outdoors	Outdoor rating, texture and drainage
Commercial space	Wear resistance and expected footfall

3.      Request written information on water absorption and slip resistance.

4.      Find out the abrasion rating for flooring.

5.      Purchase all your supplies from one batch and color.

6.      Get some extra for wastage. Installers usually recommend at least 5 to 10%.

7.      Keep some extra boxes for future needs.

How to Identify Good-Quality Porcelain Tiles

The floor tiles should be checked for evenness, clean edges, no chipping or cracking, and uniform sizes among the boxes. Two tiles should be put face-to-face to check whether there is any warping. Afterwards, the specifications and testing results from the manufacturer should be asked for.

How to Install Porcelain Tiles Correctly

First start with a good and leveled base. The adhesive that is recommended to be used in installing porcelain tiles should be applied by using the appropriate size trowel and the adhesive must cover the entire backside of the tiles. Your joints must be kept leveled and movement joints should be considered when dealing with large surfaces. Professional services are required for large slabs and these are supposed to be installed on existing floors.

How to Clean and Maintain Porcelain Tiles

Clean up daily by sweeping and damp mopping using neutral cleaner. In kitchen area, use mild degreaser and in bathroom area, eliminate soap scum before it accumulates. Stay away from acids, bleach, and steel wool. Tiles do not require any sealer but grout that is cement based may need one.

Frequently Asked Questions – (FAQs)

What are porcelain tiles made of?

Porcelain tiles are made from kaolin and other fine clays, feldspar and silica, with pigments and additives. The mix is ground, pressed at high pressure and fired until it vitrifies.

Are porcelain tiles better than ceramic tiles?

Usually, porcelain is preferable on floors and in wet areas due to being denser, more resistant to water absorption, and durable. Ceramic tiles are cheaper and easier to cut and work well on walls.

Are porcelain tiles waterproof?

Water resistance is high on the tile, although the floor that is laid will not necessarily be waterproof. Water will penetrate through the grout and the glue. Waterproofing is necessary in wet areas with proper grout and drainage for the tiles.

Are porcelain tiles slippery when wet?

This will depend on the type of finish the tile has. Glossy and polished tiles may be slippery when wet, while matte and textured tiles are not slippery. The type of finish doesn’t tell the level of slipperiness; thus, the slip-resistance rating should be requested.

How long do porcelain tiles last?

If installed properly and well-cared for, they have the potential to last many years in one’s home. Traffic, wearability rating, base, and maintenance will all come into play, and incorrect installation accounts for more damage than the actual tile itself.
