Ceramic Tile: Installation, Maintenance, and Grouting
Vetonek Complete Guide for a Perfect Finish
Installing ceramic tiles may seem straightforward, but those seeking an impeccable finish know that the details make all the difference. Poor installation can ruin even the most beautiful tile; whereas a correct installation enhances the design, maintains uniformity, and ensures exceptional durability.
At Vetonek we work every day with clients, masons, and remodelers who are looking for a perfect final result, so we have compiled this practical guide with the essential keys to correctly lay, grout, and maintain any ceramic tile.
In addition, we include special recommendations for shaded series, large formats, and choosing the type of joint, three points where the most mistakes are made.
Installation in Shaded Series
Shaded tiles are characterized by variations in tone and design between pieces. This variation is what gives them visual richness and a more natural result.
To truly appreciate all their beauty:
Essential recommendation:
Before installing, mix tiles from as many different boxes as possible.
Why?
Because this distributes the tones and patterns evenly, avoiding repetitive areas or unwanted contrasts. It is a simple step, but essential for the flooring to have a balanced and attractive finish.
Installing Large-Format Tiles
Large formats (pieces whose side exceeds 40 cm) are trending because of their modern aesthetic and sense of spaciousness. However, they require a specific technique.
1. Use leveling systems
Spacers, wedges, or self-leveling systems help prevent lippage, unevenness, and differences between pieces.
They also provide:
-
Greater installation speed
-
A completely flat surface
-
Better alignment in all joints
Their use is not optional: it is the professional and recommended way to install large formats.
2. Staggered installation
Never carry out a 50% staggered layout with rectangular pieces or large formats.
The reason is that it can accentuate small natural curvature in the tile, creating noticeable unevenness.
Correct recommendation:
The overlap should not exceed 20% of the long side.
Flooring and tiling joints
Joints are a key technical element. They are not there for aesthetics alone: they allow small dimensional variations to be absorbed, prevent stress in the flooring, and promote the durability of the covering.
Installation joints
The minimum spacing between tiles depends on the type of edge:
-
Rectified tiles: never less than 1.5 mm
-
Irregular edge: minimum 3 mm
-
Modular models (several combined formats): 5 mm to ensure correct modular coordination
Trying to install tiles “without a joint” is bad practice: it can cause lifting, cracking, or breakage due to the material's natural movement.
Movement joints
They allow the covering to expand, contract, or adapt to the building's conditions. They should not be ignored.
1. Structural joints
The building's joints must always be respected, extending them through the flooring and tiling.
2. Perimeter joints
They are placed around the entire perimeter of the floor: walls, columns, stairs…
The recommended size is greater than 5 mm, filled with an elastic material.
They are hidden behind the baseboard.
3. Expansion joints
They divide large surfaces to prevent stress.
The maximum surface without joints is:
-
Up to 60 m² indoors
-
Half that outdoors (30 m²)
They must also be at least 5 mm.
Grouting: key to a professional finish
Grouting should always be done when the adhesive has fully hardened , otherwise the pieces can shift or lose adhesion.
The correct process:
-
Apply the material with a rubber spatula or grouting trowel.
-
Completely fill the joints with firm back-and-forth movements.
-
Remove the excess and clean at the appropriate time, according to the manufacturer's instructions.
Types of grouting materials
Grout does not just close joints: it defines the aesthetic and affects the durability, hygiene, and resistance of the surface.
1. Cementitious joints (CG1 and CG2)
The most common. Made up of cement, mineral fillers, and additives.
-
Compatible with practically all tiles
-
For indoor and outdoor use
-
Available in multiple colors
-
Not recommended for commercial kitchens, sanitary areas, or places subject to aggressive cleaning
CG1: standard
CG2: improved (greater resistance, less absorption, higher durability)
2. Reactive resin joints (RG)
Based on epoxy or synthetic resins. The most resistant type.
Advantages:
-
Maximum chemical resistance
-
Very high durability
-
Bacteriological resistance
-
Total impermeability
-
Perfect for industrial kitchens, pools, spas, hospitals, or areas subject to intensive cleaning
Their installation requires more experience.
Important recommendation
Avoid joints that contain carbon black or pigments that are difficult to clean, since they can mark the surface or leave veils that are difficult to remove.
Basic maintenance of ceramic tile
Ceramic is a very durable material and easy to maintain, but following these guidelines significantly extends its lifespan:
-
Clean with neutral, non-abrasive products
-
Avoid waxes or polishes that create layers
-
Outdoors, keep movement joints clean
-
Regrout if wear appears over the years
-
Avoid products with acids not recommended by the manufacturer
Good maintenance ensures that the design, color, and texture stay as they were on the first day.
Conclusion
Installing a ceramic tile is not complicated, but it does require following certain technical criteria to achieve a perfect, long-lasting finish. Respecting the joints, leveling correctly, mixing boxes from shade-varied batches, and choosing the right grout are key steps that make all the difference.
