Du Lastik

Ready to Use High Performance Adhesive

scroll down

Dubond’s DU Lastik is superior-technology, professional, ready-to-use adhesive with high elasticity and anti skid property. Ideal for high-resistance laying of homogeneous tiles, glass mosaic, ceramic tiles, large formats and stable natural stone, on absorbent and deformable substrates, gypsum, anhydrite, wood and water-stable derivatives, on both flooring and walls, in internal environments. External use on walls. The DU Lastik technology confers superior elasticity guaranteeing the highperformance laying of all types of ceramic and homogeneous tiles on highly flexible or deformable substrates. The use of specific modifies, electromeric co-polymers with permanent effect confers high levels of absorption of dimensional substrate movements without stressing the covering.

Features & Benefits


Ready-to-use organic mineral adhesive for high-adhesion

High-deformation laying with no vertical slip


Safeguards the health of both operators and the environment

It develops high elasticity and a long adjustability time making it possible to quickly and safely lay coverings on flexible or deformable substrates, even diagonally without creating any tension in the covering

Method of Application

Preparation of substrates

  • The substrate must be even, dry, free from dust, oil and grease, with no rising damp or loose, flaky or imperfectly anchored parts. Uneven areas must be corrected in advance with suitable finishing products
  • A primer is normally not necessary when laying on gypsum or anhydrite. Nevertheless check that the substrate is perfectly dry, laid in a single layer and without any thin finishing, that may be imperfectly anchored and therefore not suitable for the tile covering


Du Lastik should be applied directly to the substrate with a suitable toothed spreader; use a quantity of adhesive sufficient to ensure full tile wettability of the back. Lay tiles while the adhesive is fresh, pressing them lightly to ensure perfect adhesion. Ceramic tiles do not normally have to be wetted in advance, however check for any traces of dust or dirt.


Du Lastik is ready-to-use and does not need any preparation. In any case, before use it is advisable to remix the product well inside the container to ensure the mixture is of an even consistency. The high thixotropy of Du Lastik means it can also be used on walls. Any excess adhesive can be kept for later use by putting the lid back on the container.

Precautions & Limitations

  • Do not use the adhesive to correct substrate irregularities
  • lay and press tiles onto fresh adhesive making sure it has not formed a surface skin Use the double-spread technique for all external laying
  • The temperature, ventilation and absorption of the substrate and covering materials, may vary the adhesive workability and setting time
  • Do not use On external floors, on wet surfaces or substrates subjected to moisture rising; in environments where water is always present; with low absorption tiles on non-absorbent substrates


This shall depend on the nature and flatness of the surface and the method of application, but at 1mm thickness it is 2 approximately 2 – 4 Kg / M with a suitable serrated trowel ( serrations of not more than 7mm ) . For good coverage, it is vitally important that all surfaces should be clean, smooth, plumb, level and free from defects and undulations.
