Porcelain stoneware is considered one of the most durable finishing materials, but it also has its vulnerable points. Most damage occurs not because of poor tile quality, but due to improper use, maintenance, or installation. Let us look at what can damage porcelain stoneware and how to avoid common mistakes that shorten the lifespan of the surface.

Abrasive Cleaning Products and Harsh Cleaning Tools

One of the most common causes of scratches and surface dulling is the use of unsuitable cleaning products and tools. Polished and lappato collections are particularly sensitive, as their glossy surfaces can easily lose their shine due to fine abrasive particles.

Porcelain stoneware can be damaged by the following tools and products:

• hard metal brushes and abrasive dishwashing sponges;
• powdered cleaning products containing coarse particles;
• products with a high concentration of acid used without first testing them on an inconspicuous area;
• mops with worn-out pads that may contain grains of sand or small debris.

More information about which products are safe for different types of surfaces can be found in the article on porcelain stoneware care.

Sand and Small Debris Underfoot

Porcelain stoneware is highly resistant to abrasion, but constant friction against hard particles can gradually leave micro-scratches even on a durable surface. This most often happens in entrance areas, where sand and outdoor dirt are brought in on footwear; under furniture and household appliances if their legs do not have protective pads; and when heavy objects are dragged across the floor instead of being lifted or moved using protective supports.

Regular cleaning of entrance areas and the use of protective furniture pads are simple ways to prevent this type of damage over the long term.

Sharp Impacts on Edges and Corners

The flat surface of porcelain stoneware can withstand significant loads, but tile edges and corners are more vulnerable to concentrated impacts. The surface can be damaged by dropping a heavy object onto the corner of a tile or onto a joint between tiles; moving furniture with sharp metal legs carelessly; or striking the surface with a tool during renovation work near already installed tiles.

This is especially relevant for porcelain stoneware countertops — a thin edge is more sensitive to concentrated impacts than the solid surface of the slab. Guidelines for careful use of such products are described in the article on porcelain stoneware countertop care.

Unsuitable Chemicals for Removing Stains

Not all household cleaning products are equally safe for porcelain stoneware. The appearance of the surface can be damaged by using:

• concentrated hydrochloric acid or another strong acid without dilution — it may damage the glazed layer or alter the color of the grout;
• large amounts of solvents or acetone on textured and porous surfaces;
• chlorine-containing products on colored collections — localized discoloration or changes in tone may occur.

Before using a new cleaning product, it is advisable to test it on a small, inconspicuous area — this applies to both flooring and work surfaces.

Installation Mistakes That Become Apparent Over Time

Some porcelain stoneware damage is caused not by everyday use, but by violations of installation technology. Common mistakes include:

1. Installing tiles on an uneven substrate, which creates voids underneath the tiles — over time, this can lead to cracking under concentrated loads.
2. Using standard tile adhesive instead of a flexible adhesive designed for large-format slabs.
3. Completely jointless installation without technological gaps to compensate for thermal expansion and movement.
4. Allowing insufficient drying time for adhesive or waterproofing before proceeding with subsequent stages of work.

A detailed overview of such installation mistakes can be found in the article about errors when choosing and installing porcelain stoneware — most problems that may appear to be «tile defects» actually arise during the installation stage.

Sudden Temperature Changes Without Considering Operating Conditions

For outdoor porcelain stoneware and collections used on terraces or near fireplaces, it is important to consider the material’s frost resistance and heat resistance. The surface can be damaged if you:

• use a collection that is not designed for outdoor conditions on a terrace or building plinth;
• expose the tile to sudden temperature changes, for example by placing extremely hot cookware on the same area of a countertop immediately after it has been exposed to cold temperatures, without considering the thermal resistance of the specific product;
• install porcelain stoneware near a fireplace without following recommendations for choosing a suitable collection — this topic is covered in more detail in the article on selecting porcelain stoneware for fireplace cladding.

How to Avoid Damage: Brief Recommendations

To keep porcelain stoneware looking like new for many years, it is enough to follow a few simple rules: use soft cleaning tools and neutral cleaning products without abrasive particles; promptly remove sand and small debris, especially in entrance areas; install protective pads on furniture legs; test new cleaning products on an inconspicuous area before using them regularly; and entrust installation to professionals who use adhesives and installation techniques suitable for the size and type of tile.

How Low-Quality Grout and Adhesive Affect the Surface

Sometimes the deterioration in the appearance of porcelain stoneware is caused not by the tile itself, but by the materials used during installation. Unsuitable grout may darken over time, absorb dirt, or crack, visually spoiling the appearance of the entire surface even when the tiles themselves remain in perfect condition. Similarly, low-quality adhesive may lose its elasticity over time, increasing the risk of tiles becoming detached even with minor movement of the substrate. The selection of compatible materials is discussed in detail in the article on choosing grout for porcelain stoneware flooring — the right combination of materials can help prevent such problems for many years.

Porcelain stoneware is a strong and durable material, but it can be damaged by improper maintenance, mechanical impact, or violations of installation technology. Most of these problems can easily be avoided by following simple care and usage guidelines and by initially choosing a collection suitable for the specific conditions — on the Itum website, you can find a suitable option for your renovation project.
