High-performance solvent-free polyurethane screed for heavy-duty applications
Vetotop US364 is a multi-component high-performance solvent-free polyurethane screed. Once cured, the product has excellent abrasion and chemical resistance, suitable for heavy-duty applications and thermal shock resistance. Vetotop US364 provides an attractive, hard-wearing, and cleanable floor finish supplied in a 15 liters kit. Vetotop US364 is used for car park flooring systems, industrial warehouses, logistics centers, freezer rooms.
Vetotop US364 is applied in thicknesses between 6-15 mm.
Thermal shock resistance.
High abrasion and chemical resistance.
Low maintenance cost
Hygienic, impervious, and easily cleanable.
High bond, stronger than concrete cohesive strength.
BS EN476:2009 as class 1 in flame spread.
Vetotop US364 is supplied in a 15 Liters Kit. Consumption: 1.50 m²/kit @ 10 mm thickness.
Vetoprime EP491 is supplied in 4 Liters Kit. Consumption: 7 - 10 m²/Liter.
Stated consumption data are for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.
All products have a shelf life of 12 months if kept in a dry store in the original, unopened packs.
All surfaces receiving Vetotop US364 should be primed with Vetoprime EP491, designed for maximum absorption and adhesion to concrete substrates.
Add the entire content 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, apply the primer 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 take care 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 observe minimum over-coating times.
Many applicators developed a practice where the first prime coat is dressed in sharp silica sand (0.5 to 1 mm aggregate diameter) and then reprimed once the excess material has been removed. This practice is intended to increase bond strength and resist transverse shear through the development of mechanical keying. While Saveto does not object to such practices, it is important to reach the proper thickness of the polyurethane screed (Vetotop US364), excluding the thickness achieved by the priming and broadcast process.
Mixing Vetotop US364
Vetotop US364 is supplied in three pre-weighed packs (base, hardener, and aggregate), ready for immediate on-site use.
Part mixing of these components is not acceptable and will affect both the performance and appearance of the finished floor.
Mix by either a forced action mixer or a heavy-duty mobile mixer fitted with a screed Jiffy-type mixing paddle. All such equipment should be of a type and capacity approved by Saveto.
Mix the components 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 2 minutes.
Slowly, add the content of the graded aggregate pack and mix for a further 3 minutes until obtaining a completely homogeneous material.
Ensure sufficient labor and materials to make the mixing and subsequent application process a continuous one for any given, independent floor area.
Once mixed, use the material within its specified pot life.
Spread the material onto the prepared and primed substrate as soon as mixing is complete.
Spread the mixed material to the required thickness using a notched trowel or a gauged screed box, with care taken not to overwork the resin, spreading evenly.
Immediately after laying, compact the material to place either using a wood float or through the facilitation of an automatic resin trowel (helicopter). Screeding rods are useful to maintain a minimum compacted thickness of 5mm (5000 microns).
Vetotop US364 is impervious at 5mm thickness; however, in constantly wet operation areas or where a high degree of cleanliness is required, seal the surface by mixing the base and hardener of Vetotop US364 (excluding the aggregate) and applying a seal coat on the surface.
Follow all existing expansion or movement joints through the new floor surface. Choose a suitable sealant for the Vetoflex sealant range.
Remove Vetoprime EP491 and Vetotop US365 from tools and equipment with Vetonit Solvent XX400 immediately after use. Remove hardened material 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 to provide a sound, well-profiled surface. All necessary repairs should be made before application by using epoxy mortar from the Vetorep ER range. New concrete floors shall be at least 28 days old with a moisture content of less than 5% (shall earlier application be required testing of substrate for moisture conditions shall be made).
Vetotop US364 should not be applied to surfaces affected by rising dampness, potential osmosis problems, or relative humidity greater than 80%.
Vetotop US364 should not be applied to weak or friable concrete, unmodified sand/cement screeds, asphalt.
Vetotop US364 should not be installed at temperatures below 10°C or above 35°C.
The product is not designed to withstand UV exposure.
Vetotop US364 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 advice.
Ensure adequate ventilation when using the product or when using solvent for cleaning purposes and avoid inhalation of vapors.
The use of barrier creams provides additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately - Do not induce vomiting.
