Description
VURA Lastik
Multi-functional, two component reactive adhesive for the installation of tiles, natural stones & other special coverings - specially on difficult substrates such as glass, rubber, wood, metal etc. It is PU base high performance and high adhesion fixing with no vertical slip on deformable surfaces.
CHARACTERISTICS
- Able to absorb stresses
- For areas subject to light chemical attack
- Good workability
- High elasticity, extremely flexible - Resistant to ageing
- Highly Thixotropic
- For indoor and outdoor use

SUBSTRATE PREPARATION
VURA Lastik adheres to all sound, load-bearing, clean and dry substrates free of substances which may impair adhesion. Substrates must fulfill the requirements of the local standards, be properly cured, structurally sound, dimensionally stable, free of any loose or friable particles, clean, dry and free of any contaminants such as dust, dirt, oil, grease, release agent, cement laitance or efflorescence.
Coatings of insufficient load-bearing strength must be removed. VURA Lastik adheres without special pretreatment on metal, wood, concrete, plasters, cement screeds, Xylolite, fibre cement boards, chipboards, existing tile and artificial stone floors and on heated screeds.
Calcium sulphate screeds (gypsum/anhydrite, mechanically roughened and freed from dust, residual moisture ≤0.5 weight %, heated screed ≤0.3 weight %) and mastic asphalt (roughened with sand, no industrial use) as well as PVC coverings.
Plasters of mortar (at least 28 days old), cement screeds (at least 28 days old, residual moisture ≤ 2 weight %) and concrete (at least 2 months old) can be covered directly with tiles. Cement substrates should not be subject to shrinkage after the installation of the product, therefore they must be properly cured. Comply with local standards.
Depending on the substrate condition and contaminants to be removed from the surface, perform adequate preparation techniques, such as grinding or blast cleaning, in order to remove all traces of any materials that could reduce the product’s adhesion to the substrate. Cracks in substrates must be identified and sealed appropriately.
APPLICATION
Preparing the Mix
VURA Lastik are supplied in ready to mix buckets.
Part A : 96 parts by weight
Part B : 4 parts by weight
- VURA Lastik is a "reactive" adhesive. This means that it sets through chemical reaction between two components, A and B. It is very important to thoroughly mix these components together.
- The ratio of the Part A (Resin) and Part B (Hardener) is fixed and any modification could cause incorrect hardening of the product.
Applying the Mix
VURA Lastik is two component reactive adhesive and Mix Part A with Part B (in the ratio of 96:4 by weight) for use and can therefore be applied from the bucket. Pour Part B (Hardener) into Part A (Resin) and mix well until a uniform paste is obtained. It is advisable to use a low speed electric stirrer to ensure perfect mixing and avoid overheating the mix. Remember that if the components are stirred at high speed, the heat developed will considerably speed up the hardening process and, thus, shorten the time the product can be worked.
Apply the adhesive according to the generally recognized rules of the thin-bed method with a notched trowel or use the buttering-floating method instead. To ensure void-free bedding of the tiles and slabs, the adhesive layer must be of sufficient thickness.
Press the tile down to make sure that at least 60% of its surface is covered by adhesive. Tiling must be carried out on freshly applied adhesive, applying adequate pressure to ensure complete and uniform contact with the adhesive and thus optimum bond. Tiles / stones must be absolutely dry.
For exterior installations, the tile backs should be completely covered with the adhesive.
