Technical Information
Product Description

Vetotop US364 is a multi-component high performance solvent free polyurethane screed. Once cured, the product has excellent abrasion and chemical resistance that is suitable for heavy duty applications and thermal shock reisstance. Vetotop US364 provides an attractive hard wearing and cleanable floor finish it’s supplied in 15 liter kits. 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

Advantages

Thermal shock resistance.
High abrasion and chemical resistance.
Low maintenance cost
Hygienic, impervious and easily cleanable.
High bond, stronger than concrete cohesive strength.

Compiliance Standard

DIN 53457
BS EN476:2009 as class 1 in flame spread.

Application Information
Instructions for use

Priming
All surfaces receiving Vetotop US364 should be primed with Vetoprime EP491 which is designed for maximum absorption and adhesion to concrete substrates.
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.
Many applicators developed a practice where the first prime coat is dressed with a sharp silica sand (0.5 to 1 mm aggregate diameter) and then reprimed once th excess material has been removed. This practice is intended to increase bond strength and resist transverse shear through development of mechanical keying. While Saveto does not object to such practices, it is important to reach teh 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) 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 screed 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 2 minutes.
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.

Application
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 spread onto the prepared and primed substrate as soon as mixing is complete.
The mixed material should be spread to the required thickness using a notched trowel or a gauged sscreed box; with care taken not to overwork the resin, spreading evenly.
Immediately after laying, the material should be rcompacted to place either using a wood float or through the facilitation of an automatic resin trowell (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, the surface may be sealed with mixing the base and hardener of Vetotop US364 (excluding the aggregate) and applying a seal coat on the surface.

Floor Joints
All existing expansion or movement joints should be followed through the new floor surface. A suitable sealant can be choosen for the Vetoflex sealant range.

Cleaning
Vetoprime EP491 and Vetotop US365 should be removed from tools and equipment with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.

Surface Preparation

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 epoxy mortar from Vetorep ER range. New concrete floors shall be at least 28 days old with moisture content of less than 5% (shall earlier application be required testing of substrate for moisture conditions shall be made).

Limitation

Vetotop US364 should not be applied on to surfaces which are effected from, rising dampness, potential osmosis problems or have a 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 temperature below 10°C or above 35°C.
The product is not designed to withstand UV exposure.

Additional Information
Health & Sefety

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 advise.
Ensure adequate ventilation when using product or when using solvent for cleaning purposes and avoid inhalation of vapours.
The use of barrier creams provide 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 medial advice. If swallowed, seek medical attention immediately - Do not induce vomiting.
Refer to product(s) MSDS for further information.
