LANKO® Especial Plus - C1 TE cementitious tile adhesive for ceramic tiles
LANKO® Especial Plus: C1 TE cementitious adhesive for ceramic tiles
LANKO® Especial Plus is a cementitious adhesive classified C1 TE according to EN 12004, formulated for medium-to-high porosity ceramic tiles and small-format pieces. It is the general-purpose tile cement for laying floors indoors and outdoors and wall coverings indoors.
The TE designation is its strong point: extended open time, around 30 minutes at +20 °C. This means you can comb more surface before laying without a skin forming, something anyone working alone or on hot days will appreciate. It achieves an adhesion of ≥ 0.5 N/mm² that it maintains after water immersion, heat ageing and freeze-thaw cycles.
✅ Main advantages
Extended open time (TE): ~30 minutes at +20 °C to comb more surface without rushing.
Stable adhesion: ≥ 0.5 N/mm² initially and also after immersion, heat and freeze-thaw.
Pot life ≥ 30 minutes: less mortar wasted in the bucket.
Two colours: white and grey, to suit the tile and the grout joint.
Thickness 3-10 mm: absorbs small irregularities in the substrate.
Low consumption: ±4 kg/m² with single-sided application and ±7 kg/m² with double-sided application.
New builds and renovations of homes and commercial premises.
Prepared, stable cementitious substrates.

🧰 Directions for use
Check that the substrate is clean, firm, stable and free of dust, grease and laitance.
Mix the 25 kg bag with 6-6.75 litres of water, using a low-speed mixer, until you obtain a homogeneous paste.
Let the mix rest for a few minutes and stir again before using it.
Spread with a notched trowel and comb the adhesive into regular ridges, at a thickness of 3 to 10 mm.
Lay the tiles within the open time (~30 minutes at +20 °C), tapping them with a rubber mallet until the ridges are flattened.
Use double-sided application outdoors, for large tiles and in areas with heavy traffic.
Work between +5 °C and +35 °C and wait for the adhesive to harden before grouting.

💡 Professional tip: C1 is not C2. LANKO® Especial Plus is designed for porous ceramic tiles and small formats: if you are going to lay low-absorption porcelain stoneware, large formats or tiles over underfloor heating, you need a C2 adhesive. And the trick to checking open time on site is your finger: touch the combed adhesive; if it doesn't stain your finger, it has already formed a skin and must be removed and combed again, no matter how many minutes the clock says.

Where can LANKO® Especial Plus be used?
It is used on floors indoors and outdoors and on wall coverings indoors, in both new builds and renovations, on prepared, stable cementitious substrates.
How much adhesive do I need per square metre?
The approximate consumption is about 4 kg/m² with single-sided application and about 7 kg/m² with double-sided application. The application thickness ranges from 3 to 10 mm.
How is the mix prepared and what colours does it come in?
Each 25 kg bag is mixed with 6-6.75 litres of water until a homogeneous paste is obtained. It is available in two colours, white and grey, in 25 kg bags.
Frequently asked questions about Sika products (mortars, adhesives and sealants)
How do I know which size and quantity to buy?
Each product page includes the approximate yield or consumption (for example kg/m² or metres of bead per cartridge) in the "Technical specifications" section. Calculate the surface area or thickness of your project and multiply by that consumption to find out how many units you need. If in doubt, contact us with the measurements of your job.
Where can I find the complete technical data sheet (Product Data Sheet)?
The description of each product already includes the main technical data (strengths, setting times, application temperature, applicable standards, etc.), taken from the official Sika Spain Product Data Sheet. If you need the complete PDF data sheet or the safety data sheet (SDS), write to us and we will send it to you.
Do these products comply with European regulations (CE marking)?
Most Sika products carry the CE marking in accordance with the relevant European standard (for example EN 1504 for structural repair, EN 12004 for tile adhesives, EN 13888 for grouts or EN 15651 for sealants). The exact standard for each reference is detailed in the "Standards and certificates" section of its product page.
What protective equipment do I need to apply them?
It depends on the product: cement-based mortars and adhesives are usually irritating to skin and eyes (gloves, goggles and a mask are recommended), while polyurethane sealants and adhesives require good ventilation. Always check the safety section of the product page and its safety data sheet (SDS) before use.
How should I store these products and how long do they last unopened?
Shelf life and storage conditions (temperature, humidity, protection from light) vary depending on the type of product (cementitious, polyurethane, epoxy, etc.) and are stated on the packaging and in the data sheet of each reference.
