Understanding Porcelain Tiles & How to Clean Them Properly

Porcelain tile cleaning is a crucial part of maintaining both the appearance and longevity of floors—especially in busy environments like kitchens, bathrooms, offices, and retail spaces. But before we talk about the cleaning process, let’s understand what makes porcelain tiles unique and how to properly care for them.

---

What Is Porcelain Tile?

Porcelain tile is a type of ceramic tile made from fine clay and fired at much higher temperatures than standard ceramic. This process makes it extremely dense, durable, and water-resistant, making it a top choice for both domestic and commercial flooring.

There are different types of porcelain tiles, each with its own cleaning and maintenance needs:

• Glazed porcelain tiles – Feature a hard, glass-like surface layer that resists water and stains.

• Polished porcelain tiles – Mechanically buffed to a high sheen, but this opens up microscopic pores on the surface.

• Unglazed (through-body) porcelain – Colour and pattern run throughout the tile. Highly durable and ideal for high-traffic or outdoor areas.

• Textured porcelain – Designed with anti-slip surfaces for safety in wet environments.

---

Is Porcelain Really Low Maintenance?

Yes—porcelain is low maintenance, but not maintenance-free.

Because of its density, it’s resistant to water and scratches. However, grime and residues can still build up, especially in textured or unglazed varieties. Polished porcelain, despite looking smooth, has micropores that can trap stains if not sealed correctly.

In commercial settings, especially, it’s essential to implement regular professional cleaning to preserve appearance and safety standards.

How to Clean Porcelain Tiles Effectively

1. Daily/Weekly Maintenance

• Sweep or vacuum to remove grit and dry soil.

• Use a pH-neutral porcelain tile cleaner—avoid bleach, acidic, or oily products.

• Mop with clean water and microfibre pads.

2. Deep Cleaning

• Use rotary machines or oscillating scrubbers with soft brushes and tile-safe detergent.

• For grout lines, a dedicated tile and grout cleaning service can restore uniform colour and hygiene.

• In commercial environments, professional porcelain tile cleaning is often necessary to maintain slip resistance and visual appeal.

Should You Seal Porcelain Tiles?

This depends on the tile type:

• Glazed porcelain: No sealing required.

  • The glaze forms a non-porous surface layer that repels liquids and dirt.

  • Just clean regularly with a pH-neutral cleaner.

• Polished porcelain: Yes.

  • The mechanical polishing process opens up microscopic pores in the surface.

  • Option 1: Use a penetrating impregnator (solvent- or water-based) to protect without altering the look.
  • Option 2: Apply a PU sealer with SuperBond primer to create a protective surface film—ideal for commercial areas where enhanced durability and maintenance ease are priorities.

• Unglazed / Through-Body Porcelain

  • Sealing is often advised, especially in high-traffic areas or places prone to staining.

  • Although dense, unglazed porcelain can slowly absorb contaminants over time.

  • Option 1: Choose a breathable, non-film-forming impregnator to preserve the natural finish.

  • Option 2: For additional protection, particularly in commercial environments, apply PU sealer over SuperBond primer for a durable, easy-to-clean surface.

• Textured Porcelain

  • Sealing is recommended, especially in commercial environments.

  • Textured surfaces trap grime more easily, and regular cleaning may not remove it from the grooves.

  • A penetrating sealer can help prevent deep dirt absorption and make cleaning easier.

  • In commercial spaces where cleaning is frequent and hygiene is essential, a PU sealer can smooth out micro-texture slightly and provide a sealed, easy-care finish.

  • In hospitality or retail spaces, pairing sealing with a professional maintenance plan can reduce long-term labour and improve hygiene.

• Grout lines: Should always be sealed, no matter the tile type.

👉 For commercial projects, we often recommend a nanotechnology-based sealer or a water-based penetrating sealant like Fila MP90 ECO Plus or Lithofin Stainstop or topical coating like Dr Schutz PU sealer.

Dr. Schutz PU Sealer System: A Game-Changer for Porcelain Tile Maintenance

When it comes to long-term protection and easy cleaning for porcelain tiles—especially in high-traffic environments—the Dr. Schutz PU Sealer system, used with SuperBond primer, is a standout solution. It’s ideal not only for commercial spaces but also for busy homes that need extra durability without compromising on appearance.

---

Why Use Dr. Schutz PU Sealer on Porcelain Tiles?

• Enhanced Surface Protection

  PU forms a flexible, yet tough surface film that shields against stains, scratches, and chemical spills.

• Easier Cleaning & Hygiene

  Dirt, grime, and oils sit on top of the sealed surface, instead of embedding into pores or textured grooves. This makes mopping and everyday cleaning much faster and more effective.

• Aesthetic Finish Options

  Choose from matt or satin—great for both modern home interiors and stylish commercial floors.

• Slip Resistance

  Matte PU finishes add a layer of anti-slip safety, ideal for kitchens, bathrooms, entranceways, and areas where pets and children play.

• Long-Lasting Results

  The coating can last 2–5 years or much, much more, and it can be refreshed without stripping—perfect for high-traffic households and commercial areas alike.

Not Just for Businesses: Ideal for Heavy-Traffic Homes

Many families find their tiled floors are visibly worn within a few years, especially in open-plan kitchens, entrance halls, or conservatories. PU sealer can:

• Protect polished or textured porcelain from daily messes

• Make deep cleaning less frequent and more effective

• Prevent staining from food, drinks, muddy paws, or school shoes

• Provide a modern, satin finish that complements the interior design

• Improve slip resistance in areas prone to moisture or steam

Whether you have light-coloured grout that keeps looking dirty or polished porcelain that starts to dull, PU sealer offers an upgrade in both appearance and function.
