Heavy-duty epoxy-based floor screed from 3 to 25 mm thickness
Vetotop ES459 is a trowel applied floor screed composed of a three-part solvent-free combination of epoxy resin; modified amine hardener filled with specially graded chemically inert aggregates. The product performs in heavy-duty demanding applications where abrasion and impact resistance are crucial factors in product choice.
BS EN476:2009 as class 1 in flame spread.
Vetotop ES459 is supplied in a 15 Liters Kit. Theoretical Yield: 5 m²/kit @ 3mm thickness.
Vetoprime EP491 is supplied in 4 Liters Kits. Theoretical Yield: 7-10 m2/ Liter.
Stated consumption data are for general guidance. Actual consumption depends on the nature of substrate, method of application, and wastage.
The original sealed kit of Vetotop ES459 has a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded place below 35ºC.
Vetotop ES459 is designed to be a hard-wearing trowel applied epoxy screed on cementitious or metal substrates at thicknesses between 3 to 25 mm. The applied product will be resistant to water as well as a wide range of chemicals.
All surfaces receiving Vetotop ES459 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, take care to avoid over-application or ‘ponding.’ Allow the primer to become tacky before proceeding to the next stage. Porous substrates may require a second primer coat - when the first coat is directly absorbed into the substrate - but observe minimum over-coating times.
Vetotop ES459 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. For mixing, use either a forced action mixer or a heavy-duty mobile mixer fitted with a suitable 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.
The application starts 30min after primer application (at 23C0) while the primer is still tacky. Spread Vetotop ES459 to a uniform thickness on the primed surface using either a screed box or the edge of a steel trowel. The material should be tamped with a wooden float to ensure complete compaction and finally finished to a closed even texture using a steel trowel. Screeding rods are useful to maintain a minimum compacted thickness of 3 mm. Apply the material within the pot life after mixing.
Vetotop ES459 can be used to form a perimeter edge coving up to a height of 50mm. Skilled applicators can also use it to repair stair treads and fix expansion joint edges.
Although Vetotop ES459 is impervious at 3 mm thick in constantly wet operations areas or where a high degree of cleanliness is required, the Vetotop ES459 may be sealed with Vetotop EC498.
Vetotop ES459 must be at least 3 days old, and high spots such as trowel marks rubbed down.
Clean all tools and equipment immediately after use with Vetonit Solvent XX300.
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. Repair all necessary 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 ES459 is non flammable. Refer to the product material safety data sheet for information.
