Medium duty polyurethane hybrid flooring system
Vetotop UL171 is a single layer, seamless, solvent free, polyurethane flooring system with a smooth matt surface finish. It has high impact resistance and withstands abrasive wear and a wide spectrum of chemicals. The product is a 3 component system consisting of a base, hardener and powder filler.
Vetotop UL171 is supplied in 28kg Kits, with Theoretical coverage: 1.9 kg/m2 at 1mm thickness
Vetoprime UP170 is supplied in 3kg Kits, with Theoretical coverage: 10 m2 / 3 kg kit
Original sealed kit of Vetotop UL171 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded place below 25ºC.
All surfaces receiving Vetotop UL171 should be primed with Vetoprime UP170 which is designed for maximum absorption and adhesion to concrete substrates or applied over a 1mm "scratch coat" of UL171. Add the entire contents of the hardener tin to the base tin and mix the two primer components thoroughly for at least 2 minutes - only mix full packs. Once mixed, the primer should be applied immediately to the prepared substrate using stiff brushes and/or rollers. The primer should be well ‘scrubbed’ into the substrate to ensure full coverage, but care should be taken to avoid over application or ‘ponding’. Allow the primer to dry before proceeding to the next stage, do not proceed whilst the primer is ‘tacky’ as this will lead to unsightly marks in the finished surface. Porous substrates may require a second primer coat - when the first coat is directly absorbed into the substrate - but minimum over-coating times must still be observed.
Vetotop UL171 is supplied in three pre-weighed packs (base, hardener and aggregate) which are ready for immediate on-site use. Part mixing of these components is not acceptable and will affect both performance and appearance of the finished floor. Mixing should be carried out using either a forced action mixer; or a heavy duty mobile mixer fitted with a jiffy type mixing paddle. All such equipment should be of a type and capacity approved by Saveto. The components should be mixed in a suitably sized mixing vessel. Stir the base and hardener components individually then empty them into the mixing vessel scrapping the edges and mix for 30 seconds. The contents of the graded aggregate pack should be slowly added and mixing carried out for a further 3 minutes until a completely homogeneous material is obtained.
Optimum application temperature to achieve best flow and leveling qualities is done at 25-30oC; However; the UL171 can be applied at temperatures of 20-32oC. Ensure that there are sufficient labor and materials to make the mixing and subsequent application process a continuous one for any given, independent floor area. Once mixed, the material must be used within its specified pot life. The material should be poured onto the prepared and primed substrate as soon as mixing is complete. It should be spread to the required thickness using a notched trowel or a gauged spreader; with care taken not to overwork the resin, spreading evenly and slowly. Immediately after laying, the material should be rolled, using a spiked nylon roller, to remove slight trowel marks, and to assist air release. The rolling should be carried out using a ‘back and forth’ technique along the same path. An overlap of 50% with adjacent paths is recommended. Further light rolling may be required to remove surface imperfections, or for subsequent release of trapped air, but should be prior to the setting of the product.
All existing expansion or movement joints should be followed through the new floor surface.
Vetoprime UP170 and Vetotop UL171 should be removed from tools and equipment, water immediately after use. Hardened material can only be removed mechanically.
The surface should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.
Laitance and weak surface layer shall be removed using mechanical methods such as grinding or blasting in order to provide a sound well profiled surface. All necessary repairs should be made prior to application by using Vetotop US172. New concrete floors shall be at least at least 5 days old and visibly dry without standing water on top.
Grooves must be cut according to floor area to control shrinkage. Please contact Saveto for information.
Vetotop UL171 is irritant and harmful therefore avoid direct contact with eyes or skin. It is recommended to use protective gloves and goggles during application. In case of contact with eyes, clean immediately with plenty of clean cold water and seek medical advise.
Ensure adequate ventilation when using product. In case of contact with skin or eyes, rinse with plenty of clean water and seek medial advice. Keep away from sources of ignition. No Smoking. In the event of fire extinguish with CO2 or foam.
