Two-component, epoxy-polyurethane adhesive for …

1 19. x G. ile es Ad Two- component , epoxy - polyurethane adhesive for resilient and textile flooring WHERE TO USE semi-flexible quartz vinyl floor tiles (VTC);. Extremely strong, tough, elastic, adhesive for general purpose use, particularly suitable for non-absorbent textile floor coverings with all common backings substrates or moisture-sensitive substrates (wood, (latex-primed, PVC and polyurethane foam, natural metal, ceramic, stone, resin, PVC, rubber, etc.). jute and Action-Bac backed carpets etc.);. For use on floor in interior and exterior applications. Specifically developed for the installation of rubber needlepunch woven flooring also in latex;. athletic tracks. Also suitable as universal adhesive for rubber, PVC and flocked textile flooring.

2 All common resilient and textile floor covering types, linoleum with all kind of backings;. especially in the event of extreme temperatures due to solar radiation, intense mechanical stress by lift truck, polyolefin-based and chlorine-free floor coverings;. forklift, etc. or frequent washing (in particular when the floor coverings are not welded or sealed). PUR floor coverings. Some application examples TECHNICAL CHARACTERISTICS. Use Adesilex G19 for bonding: Adesilex G19 is a two- component adhesive made from an epoxy - polyurethane polymer, component A, and a rubber athletic tracks and multisport flooring on special hardener, component B. asphalt; When the two components are mixed together, they form an even coloured paste which is easy to apply with recycled rubber shock-absorbent flooring on asphalt a suitable notched trowel.

3 In playgrounds; After setting (around 24 hours), which takes place by means of a chemical reaction without any shrinking, resilient flooring for indoor sports flooring, also onto Adesilex G19 becomes though and resistant to waterproofing fiberglass underlays such as Mapelay; moisture, water, heat and atmospheric agents, and adheres extremely well to almost all materials normally homogeneous and heterogeneous PVC, sheets used in the building industry. and tiles;. RECOMMENDATIONS. CV floor coverings; Install in recommended temperatures, normally between +10 C and +30 C, in order to maintain LVT; workability and setting times.

4 G19 Do not install on substrates not protected component A: parts by weight;. ilex from rising damp. component B: parts by weight. es Ad Do not install flooring on not completely set Blend the two components together with or wet concrete (residual moisture content a mechanical mixer until an even paste is must be maximum ). obtained. Setting times and pot life depend on the ambient temperature (see table). Do not install flooring on fresh asphalt (wait Setting times are much longer if the at least 20 days). temperature is lower than +10 C. Do not install flooring on bituminous Note: the resin ( component A)/catalyser surfaces which might bleed oils. ( component B) ratio must be strictly adhered to.

5 Any variation in dosage will Do not use on curved surfaces or steps compromise the setting of the product. if it is not possible to hold the flooring in perfect adherence against the substrate Spreading the adhesive until the adhesive has set. The choice of trowel depends on the type of flooring to be installed and on the substrate: When installing thin flooring where the for smooth backings and smooth substrates ribs of adhesive may shadow through, use use MAPEI No. 1 or TKB A1, A2 trowels;. Adesilex G20 or Adesilex G20 Fast. for textured and impervious backings and substrates use MAPEI No. 2, 3, 4 or TKB B1, When a rapid adhesive with faster setting B2, C1 trowels. is needed, use Adesilex G19 Fast.

6 Only apply as much adhesive as can be covered within the open time (60 minutes). APPLICATION PROCEDURE and with good transfer to the backing of the Substrate preparation covering. Substrates must be dry, level, sound, mechanically strong, free of dust, loose Installing the flooring particles, cracks, paints, wax, oil, rust, Follow the manufacturer's instructions for traces of gypsum or other products that can laying technique. interfere with bonding.

Commonly, the moisture content must be Take care to avoid air pockets and carefully as follows: max.

Avoid anhydrite-based substrates. excessive stress at the seams. After installing It is essential to make sure there is no rising the floor covering, it is always necessary to damp present. Un-bonded screeds laid carefully roll it down again or to firmly rub it over light-weight concrete or over insulation down. and screeds laid directly onto earth must If the flooring is not perfectly flat, put weights be separated by a vapour barrier to prevent (such as bags of sand or similar) on the rising damp. uneven areas, and on the joints and roll To repair cracks in the substrate, consolidate ends until the Adesilex G19 has hardened and waterproof screeds, form new fast-drying (12-24 hours).

Adesilex G20 or Adesilex G20 Fast (eventually mixed with suitable quartz or The setting time of Adesilex G19 at different crumbled rubber) for repairing or smoothing temperatures is the following: asphalt surfaces.

Acclimatisation CONSUMPTION. Before starting the installation, make Consumption varies according to the flatness sure that the floor covering and substrate of the substrate and the type of backing on are acclimatised to the recommended the flooring material (and, therefore, the type temperatures and of trowel used): trowel No. 1 or TKB A1/A2: 350-450 g/m ;. Mixing the adhesive trowel No. 2 or TKB B1; B2: 450-550 g/m ;. The two components of Adesilex G19 are trowel No. 3 or TKB C1: 550-750 g/m.
