LITOKOL LITOELASTIC EVO – 5kg and 10kg

 

GENERAL

Litokol Litoelastic EVO is a white two-component flexible reactive adhesive, water and solvent free, with high water resistance. Component A consists of synthetic resins, inert fillers with fine granulometry and specific organic additives. Part B consists of an innovative organic catalyst. Once mixed together, the two components form an easily workable, thixotropic and particularly fluid paste that facilitates the work of installers.

PRE-INSTALLATION

The substrates must be clean, solid, compact, crack-free, properly cured and without rising damp.

Use of primer:
• Excessively porous and absorbent or powdery substrates must be treated with the consolidating primer Primer C. The application of Primer C on absorbent surfaces improves the fluid application of the mix while also improving the level of adhesion
• Smooth and compact substrates such as smoothed concrete, existing ceramic or agglomerate coverings, must be treated with the adhesion promoter primer Prepara Fondo EVO after being suitably degreased with specific detergents such as Litoscrub EVO
• In the case of anhydrite screeds, check for the presence of a suitable vapour barrier in order to prevent rising damp. Use a carbide method hygrometer to check that the residual humidity is less than 0.5%. The surface must be sanded and treated with Primer C
• Any cracks must be repaired with Multifondo EVO, sprinkling the fresh surface with sand or dried quartz with granulometry 0.4-1 mm
In any case, the respective technical data sheets must be consulted for correct use of the indicated products.

Expansion joints
Check that the perimeter, expansion, divider and structural elastic joints have been correctly designed and prepared. Divider joints are normally required for sections equal to 50 m2 or 25/30 m2 in the case of underfloor heating.
In areas with surfaces less than 50 m2 expansion joints must nonetheless be inserted along each of the door thresholds.

 

MIX RATIO

Component A 92.6 parts by weight – Component B 7.4 parts by weight. The two components are pre-batched in their respective packaging.

 

PREPARING THE MIX

Pour part B (catalyst) onto part A (paste).
We recommend pouring all the catalyst contained in the bag.
Mix, preferably using an electric drill with mixing paddle at low speed (≈ 300/min.) until a consistent mix is obtained without lumps.
Hand mixing is not recommended.
The two components are pre-batched in their packaging, thus preventing mixing errors.

 

APPLICATION

Spread the Litokol Litoelastic EVO mixture onto the substrate using the smooth part of the trowel to create a layer approximately 1 mm thick.
Immediately afterwards, spread additional Litokol Litoelastic EVO using the notched part of the trowel.
The trowel notch size will depend on the size of the tiles.
A back coverage of 65-70% is nonetheless required for interior installations, and 100% for exterior installations, floors subject to heavy traffic or mechanical stress, and swimming pools.
The tiles must be laid on the adhesive when fresh, firmly pressed to ensure good contact.
The tiles must be installed with joint widths suitable for their size.
Take account of any expansion, perimeter, divider or structural joints.
Leave a space of at least 5 mm near walls or any surface elevations.
In the case of single-step waterproofing and installation of ceramic materials or mosaics in shower enclosures or indoor wet areas, at least 1 mm of product must first be applied to the relevant area using a smooth trowel.
After setting (about 24 hours), spread the product using a notched trowel to install the ceramic materials.

 

FOCUS

Marble, natural and recomposed stones
Materials subject to deformation or stains due to water absorption require a quick-setting (C2F) or reactive (R2) adhesive. Marble and natural stones, even if similar in nature, may have different characteristics. In case of doubt, contact the Litokol S.p.A. Technical Help Service for detailed information or to perform a laboratory test. Natural stone slabs with reinforced backing (resin, mesh, etc.) or specific treatments (for example anti-rising damp, etc.), unless otherwise prescribed by the manufacturer must be tested for compatibility with the adhesive. Before installation, check for any traces of dirt or material deposits on the back of the slabs. If so, these must be removed.

Façades
For exterior wall installations (H>3 m) where tiled surfaces are subject to high levels of tension in expansion joints due to the variations in air temperature and relative humidity and considering the safety risks posed by any eventual detachments, it is recommended to consult the Litokol S.p.A Technical Help Service in order to precisely define the safest type of installation. In accordance with standard UNI 11493 – point 7.13.7), follow these general instructions: the substrate must guarantee a cohesive tensile strength ≥ 1.0 N/mm2. For coverings with side > 30 cm the designer must evaluate the potential need to use suitable mechanical fasteners for safety purposes. Always spread the adhesive directly onto the back of the material also.

Underfloor heating
After at least 4 days from installation of the screed developed with Litocem or Litocem Pronto, the heating system can be used with a variable supply water temperature between +20°C and +25°C, kept constant for at least 3 days.
Then set the maximum design temperature and hold it for another 4 days. At the end of this cycle, bring the screed back to ambient temperature and install the covering (see standard EN 1264-4).

Swimming pools
Litokol Litoelastic EVO can be applied directly on the concrete substrate or Elastocem, Coverflex, Aquamaster and Litoproof Extreme elastic waterproofing membranes.
Following is a list of precautions that must be followed when installing the coverings:
Respect the concrete curing time (minimum 6 months)
For underground tanks, adopt preventive measures against possible capillary rising damp, which may cause the detachment of the waterproofing membrane applied inside the tank, for example on drains along the side walls of the excavations or waterproofing constituted by osmotic mortars such as Osmogrout
Rectify the surfaces using suitable cementitious mortars such as Litoplan Smart
Waterproof the internal surfaces of the tank with flexible waterproof membranes resistant to contact with chlorinated water such as Elastocem, Coverflex, Aquamaster and Litoproof Extreme
It is advisable to perform a hydraulic seal test before installing the covering

Bonding of insulation panels
It can be applied either with a notched trowel or in certain points, nonetheless in accordance with the product’s open time.
In any case, the quantity of adhesive applied should be sufficient to ensure the panels are securely bonded.
The slabs must then be installed by applying adequate pressure to obtain a suitable level of adhesion.

 

TILE INSTALLATION

Coverings can be installed after at least 24 hours have passed since the last coat.
Ceramics, natural stones or mosaics can be installed with cementitious adhesives in class C2 or reactive in class R2 according to UNI EN 12004.
The choice of adhesive depends on the size of the tiles and expected operating conditions.
In the case of large tiles (side > 60 cm), it is preferable to use deformable adhesives in class S1 or highly deformable adhesives in class S2.
The tiles must be installed with a solid bed using the back-buttering technique, with joint widths suited to their size. For the correct choice of adhesive, refer to the technical data sheets of the products.

 

GROUTING

After tiling using Litokol Litoelastic EVO, joints can be grouted after approximately 6-8 hours in the case of wall tiles and after 24 hours in the case of floor tiles.
For grouting, it is possible to use the cementitious grouts Stylegrout 0-8, Stylegrout 3-20, Stylegrout Tech or the ready-to-use polymer mortar FillGood EVO, or, for grouting with special mechanical and chemical resistance, the two-component epoxy grouts Starlike® EVO or EpoxyÉlite EVO.
