Yes, our cement tiles are suitable for underfloor heating systems. Make sure to turn off the heating at least 12 hours before installation and allow a minimum 3 mm grout gap. Once installed, let the tiles fully cure before reactivating the heating gradually.

Yes, Otto cement tiles are suitable for installation around fireplaces, such as fireplace surrounds and hearth-facing walls. However, they are not recommended for use inside fireboxes (the interior of the fireplace where direct flame and extreme heat occur), as this may cause damage over time.

No. Cement tiles are not suitable for submerged or continuously wet applications such as pools, fountains, or water features. Their porous nature makes them vulnerable to long-term water absorption, even when sealed.

Yes, Otto cement tiles are highly versatile. They can be used on walls, floors, and in high-traffic areas, both indoors and outdoors. They are also suitable for kitchen backsplashes, bathrooms, showers, and fireplace surrounds (excluding inside fireboxes). However, these tiles are not recommended for use in pools or fountains.

Cement tiles can stain if not properly sealed. This is why sealing before and after grouting is essential. During installation, only grout small sections (2–4 sqm) at a time and clean immediately with a damp sponge. If haze or residue is left on the surface, it can often be removed with non-acidic tile cleaners—but be sure to rinse thoroughly. Grout staining typically occurs only if proper sealing and installation practices aren’t followed.

Absolutely. Due to their porous nature, cement tiles must be sealed both before and after grouting. We strongly recommend using Lithofin MN Stain Stop, a transparent penetrating sealant that won’t alter the tile’s appearance. Apply the sealant to a clean, dry surface using a cloth, brush, or sponge. Always test on a small area first. If water does not bead on the surface, additional sealing may be required. For high-traffic areas or bathrooms, we advise resealing once a year.

For regular cleaning, sweep or vacuum gently and mop with clean water and a pH-neutral cleaner. Avoid harsh chemicals, bleach, vinegar, or acidic products. After shower use, squeegee the tile surfaces to prevent limescale or soap scum buildup. For deeper stains, a wet grinding machine with 400-grit sandpaper can be used to lightly polish the surface—just be sure to reseal afterward.

Otto cement tiles are handmade using a mix of natural pigments, cement, recycled marble granules, and marble powder. Unlike ceramic or porcelain tiles, they are not fired in a kiln—making them far more eco-friendly. What makes our cement tiles stand out is their thick 7–8mm colour layer, which allows for sanding and refinishing over time. The tiles are designed to look authentically handmade, with slight imperfections and variations that enhance their artisanal character.

Yes, they are. If installing over underfloor heating, the heating system must be turned off at least 12 hours prior to laying the tiles. A 3 mm grout gap should be left to accommodate expansion. Once installation and grouting are complete, allow for a full curing period before turning the heating back on gradually.

Yes, Slim Line cement tiles can be used around fireplaces, similar to our standard cement tiles. They provide a beautiful handcrafted look for hearth surrounds and fireplace wall features. However, like standard cement tiles, they are not suitable for installation inside fireboxes.

Yes, they are. Our Slim Line tiles are engineered for strength and versatility. They can be used on floors and walls in both residential and commercial settings, including kitchens, bathrooms, hallways, showers, and wet areas. As with all cement tiles, a proper substrate and professional installation are crucial to ensuring long-term durability.

No. Slim Line tiles are also not suitable for submerged areas such as pools or fountains. While durable and resistant to surface wear, they are porous and can absorb water over time, even with sealing. They can be used in surrounding areas, such as pool decks or waterline borders, when finished with a specialized pool-grade sealant

Yes, if not properly sealed or cleaned during installation. Always seal tiles before applying grout, especially if using dark grout. Grout haze or staining can occur if excess grout is not removed immediately. Avoid letting grout dry on the surface, and clean as you go in small areas (2–4 sqm). If grout hardens, use a non-acidic cleaner and rinse thoroughly with a damp sponge.

Yes, sealing is essential. Like all cement tiles, Slim Line tiles are porous and must be sealed both before and after grouting. We recommend Lithofin MN Stain Stop, which is a transparent penetrating sealer that won’t alter the tile’s natural look. Always apply to a clean, dry surface and test a small area first. A properly sealed tile will bead water on the surface; if not, another coat is needed. Re-sealing is recommended annually for high-use areas.

Clean regularly with water and a pH-neutral cleaner. Avoid acidic or abrasive products. In showers or wet areas, squeegee surfaces after each use to prevent soap and limescale buildup. Any stubborn stains can be addressed with a wet grinding machine (using 400-grit sandpaper), but tiles must be resealed afterward. Annual sealing is typically sufficient, though more frequent reapplication may be necessary in high-moisture zones like showers.
