- \n
- Dryness:<\/strong> The residual moisture of the screed must not exceed 0.5% CM for calcium sulfate screeds and 2% CM for cement screeds.<\/li>\n\n\n\n
- Evenness: <\/strong>According to DIN 18202, deviations must not exceed 3 mm over a measuring length of 2 m.<\/li>\n\n\n\n
- Load-bearing capacity:<\/strong> No cracks, no hollow spots, no loose layers.<\/li>\n<\/ul>\n\n
For heated floors (underfloor heating), a documented heating and cooling protocol is required. Without proper preconditioning, thermal stresses can cause the adhesive bond to break. The protocol ensures that the screed dries evenly and without tension \u2013 a crucial prerequisite for the long-term adhesion of the tiles. <\/p>\n\n
A deep-penetrating mineral primer<\/strong> is recommended to balance absorbency and improve adhesion.<\/p>\n\n

Terracotta Fliesen werden frisch ins Kleberbett gesetzt \u2013 pr\u00e4zise ausgerichtet.<\/figcaption><\/figure>\n\n Handmade terracotta tiles naturally show variations in color, texture, and size. This is not a flaw but a true expression of their artisanal origin. To achieve a harmonious overall appearance, it is recommended to: <\/p>\n\n
- \n
- Mix tiles from at least three boxes in advance<\/strong><\/li>\n\n\n\n
- Dry-lay the tiles on the surface<\/strong> to check transitions and color flow<\/li>\n\n\n\n
- Define the laying pattern beforehand<\/strong> <\/li>\n<\/ul>\n\n
Joints in natural stone and terracotta flooring serve two purposes: they compensate for dimensional tolerances and significantly influence the overall appearance of the floor.<\/p>\n\n
Recommendations<\/h3>\n\n
- \n
- Joint width: at least 4\u20136 mm<\/strong>, depending on tile format and dimensional tolerance<\/li>\n\n\n\n
- Grout cement-based, flexible, and permeable to water vapor<\/strong><\/li>\n\n\n\n
- Grout color<\/strong> should be coordinated with the terracotta tone \u2013 either \u201ctone-on-tone\u201d or deliberately contrasting<\/li>\n<\/ul>\n\n
Mistakes to Avoid<\/strong><\/p>\n\n
- \n
- Joints that are too narrow increase tension and risk of cracking<\/li>\n\n\n\n
- Mortar edge staining can occur on unsealed tiles if no impregnation is applied before grouting<\/li>\n<\/ul>\n\n

Not every tile adhesive<\/a> is appropriate for terracotta. Due to its high capillary absorption, specially formulated adhesives are recommended: <\/p>\n\n
- \n
- Cement-based flexible adhesives (C2 TE S1)<\/strong> with extended open time<\/li>\n\n\n\n
- Avoid dispersion adhesives<\/strong>, as they block breathability<\/li>\n\n\n\n
- Use the buttering-floating method<\/strong>, meaning apply adhesive both on the subfloor and on the back of the tile<\/li>\n<\/ul>\n\n
Additional Tip<\/h3>\n\n
A too rapid withdrawal of water from the adhesive (e.g., due to highly absorbent tiles) can reduce bonding performance. In such cases, it is advisable to lightly moisten the back of the tiles. <\/p>\n\n
After laying terracotta tiles, impregnation<\/a> protects the surface. Terracotta tiles must be impregnated before<\/strong> grouting. The reason is that cement-based grout contains fine particles that can penetrate the open-pored structure and leave permanently visible stains or edge marks. <\/p>\n\n
Impregnation Process:<\/h3>\n\n
- \n
- First coat: before grouting \u2013 transparent, non-film-forming, and non-layer-forming<\/li>\n\n\n\n
- Second coat: after final cleaning<\/li>\n\n\n\n
- Optional: finish or wax to enhance the visual appearance<\/li>\n<\/ul>\n\n
Choice of Impregnation Products<\/h3>\n\n
- \n
- Oil-based impregnation:<\/strong> enhances color, creates a warm appearance, ideal for living areas<\/li>\n\n\n\n
- Silicate-based:<\/strong> matte finish, deep penetration, suitable for high-traffic zones<\/li>\n\n\n\n
- Silicone-resin-based: <\/strong>combines protection with slight color enhancement, potentially suitable for outdoor areas<\/li>\n<\/ul>\n\n

An impregnated terracotta floor is easy to maintain \u2013 as long as it is treated correctly.<\/p>\n\n
- \n
- pH-neutral cleaning solution<\/strong>: use regularly and sparingly<\/li>\n\n\n\n
- Avoid steam cleaners<\/strong> as well as chlorine- or acid-based products<\/li>\n\n\n\n
- Refresh impregnation every 1\u20133 years<\/strong>, depending on the level of use<\/li>\n<\/ul>\n\n
Over time, a natural patina develops that should never be mistaken for dirt: it reflects use, history, and warmth. If desired, this patina can be further enhanced with a care wax. <\/p>\n\n
Terracotta is a natural product with centuries of tradition. Anyone who chooses this flooring should not treat it like a mass-produced material. With proper planning, suitable materials, and skilled craftsmanship, laying terracotta tiles<\/strong> results in a floor that lasts for generations and becomes even more beautiful over time. <\/p>\n\n
