Laying Large Format Tiles – Tools for Precision Installation by Karl Dahm
Large format tiles are a modern trend – but their installation requires the utmost precision and technical skill. For decades, Karl Dahm has been providing professional tools specifically tailored to the demands of large format tiling. From cutting and handling to laying and grouting – our solutions ensure smooth, clean, and ergonomic installation of large tiles.
Edge Processing & Adhesion
Cutting large-format tiles demands exceptional accuracy. Tile cutters such as the Dahm High-Line Plus with patented guide system allow for precise straight cuts on tiles up to over 3 m in length. For even larger formats, the MK2 Large Format Tile Cutter comes into play – featuring a ball-bearing-mounted cutting carriage and extendable guide rail.
For accurate snapping, even of narrow strips, specialised tools such as the Ideal Breaker Pliers or the Superknacker are recommended. Clean edge cuts are ensured by using vacuum lifters for secure positioning.
Drilling into large tiles is another challenge: diamond dry drill bits combined with an angle grinder or a stationary drill stand with vacuum base allow for safe and clean drilling without slippage. Especially for thin formats from 3 mm, a precise drilling angle is essential to avoid tile damage and ensure proper cooling of the diamond edge.
To ensure full-surface bonding, the buttering-floating method is recommended. In this technique, adhesive is applied not only to the substrate but also to the tile's back. It’s crucial that all corners and edges are covered evenly. Notched trowels with large teeth, like the flexible notched trowel, guarantee optimum contact and adhesion.
AKEMI Colour Bond / Everclear
Large and thin tiles require extra care in bonding – especially in visible areas. With transparent or colour-matched adhesive systems like AKEMI Colour Bond or Everclear, even light and translucent tile materials can be bonded invisibly.
These products are specifically formulated for porcelain and natural stone, providing reliable adhesion without discolouration, preserving the tile’s original look. Their ease of use and strong final bonding strength make them a trusted site solution.
Natural Stone Processing
Working with natural stone requires sensitivity and specialised equipment. For cutting, grinding and milling delicate surfaces, Karl Dahm offers a range of professional tools. Used together with AKEMI cleaners, polishers and protection systems, materials like marble and granite can be treated effectively and gently.
Karl Dahm also supplies plastic corner protectors for tile thicknesses from 3–10 mm to ensure safe transport and placement. These are indispensable for thin, large-format slabs to protect edges during handling.
Lifting Aids & Tile Hoists
Large tiles are bulky and heavy – proper lifting and handling aids are essential. Suction lifters with single or double lips, as well as versions with hand pumps, ensure reliable grip – even on textured surfaces. Pro tip: slightly moistening the rubber lip improves suction power.
For lifting and precise placement of large tiles, a lifting and placing frame such as the X-Lift Frame is ideal. Specially developed for large formats, it features adjustable crossbars, vacuum cups with pressure indicators, and an ergonomic handle for safe handling. The "Big Size" version offers maximum stability and flexibility for different tile dimensions.
Used in combination with an electric tile hoist like the X-Lift, overhead installation becomes much easier and significantly less physically demanding – allowing for accurate mounting even at height.
Substrate Preparation
A level and stable substrate is the foundation of any successful tile job. For this, self-levelling compounds, smoothing trowels, and levelling bars are used. Spike rollers help release air bubbles in the compound, ensuring a smooth surface. To walk on the fresh surface without damaging it, spiked shoes are essential.
Before levelling, use precision wedges to detect and eliminate height variations. Only then can a completely flat surface be guaranteed – which is vital for laying large tiles seamlessly.
Karl Dahm’s proven tile levelling system allows millimetre-accurate alignment of tile edges. Without the need for additional tools, the reusable cap is screwed onto the threaded base to create even transitions and eliminate lippage. The result: a perfect grout line and seamless tile level.
FAQ – Frequently Asked Questions about Large Format Tile Installation
Which tools are needed for cutting large tiles? Tile cutters with extended cutting lengths (e.g. High-Line or MK2) are recommended. Narrow strips can be snapped using Ideal Breaker Pliers or the Superknacker. For drilling, use diamond dry bits with an angle grinder or stationary vacuum drill stand.
How do I avoid lippage when tiling? A high-quality levelling system like the Karl Dahm system eliminates height differences. The screw-on cap and threaded spacer create a level surface without additional tools.
Which adhesive method is best for large tiles? Use the buttering-floating technique: apply adhesive to both the substrate and the back of the tile to ensure full-surface contact. Large notches on your trowel help achieve an even bed.
What should I consider when preparing the substrate? The surface must be dry, clean, crack-free and level. Use levelling compounds, spike rollers and spiked shoes for optimum preparation. Precision wedges help measure and correct uneven spots.
Which lifting aids are suitable for large tiles? Suction lifters with double lips or hand pumps provide secure hold. For very large tiles, use a lifting frame like the X-Lift – ideally combined with a powered hoist for overhead work.
How do I prevent damage during transport? Use plastic edge protectors for tile corners and sides. These safeguard fragile edges during movement and handling.
Do I need special adhesive for translucent or light tiles? Yes, AKEMI Colour Bond and Everclear are perfect for transparent bonding without discolouration – ideal for glass, porcelain and natural stone.
Are there training sessions on large format tile installation? Yes. Karl Dahm regularly offers seminars and workshops on large format tiling – including hands-on sessions with our tools. Contact us for more details.
