The surface should be sound, clean, free from loose material, grease, laitance, dirt-curing compounds, etc. 

Laitance and weak surface layers should be removed using mechanical methods such as grinding or blasting to provide a sound, well-profiled surface. Make all the necessary repairs before applying by using an epoxy mortar from the Vetorep ER range. New concrete floors should be at least 28 days old with a moisture content of less than 5% (for earlier applications, test the moisture conditions of the substrate).

All surfaces receiving Vetotop ES459 should be primed with Vetoprime EP491 (which is 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 (Do NOT mix partial quantities). 

Once mixed, apply the primer immediately to the prepared substrate using a stiff brush and/or a roller. The primer should be ‘scrubbed’ well into the substrate to ensure full coverage. Avoid over-application or ‘ponding.’ 

Allow the primer to dry before proceeding to the next stage, do not proceed while the primer is ‘tacky’ as this will lead to unsightly marks in the finished surface. Porous substrates may require a second primer coat (this can occur when the first coat is directly absorbed into the substrate. Observe minimum overcoating times before using this product).

Vetotop ES459 is supplied in three pre-weighed packs (base, hardener, and aggregate), ready for immediate on-site use. Avoid mixing partial quantities of these components as it will affect both the performance and appearance of the finished floor. 

Mixing should be done 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 container. 

Stir the base and hardener components individually, then empty them into the mixing container (make sure to scrape the edges), and mix for 2 minutes. Add the contents of the graded aggregate pack slowly and mix for another 3 minutes until a completely homogeneous mix is obtained.

Begin the application process 30 minutes after applying the primer (at 23°C & 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. 

Finally, the layer should be finished to a closed & even texture using a steel trowel. Screeding rods are useful to maintain a minimum compacted thickness of 3 mm. After mixing, apply the material within the pot life.

Vetotop ES459 can be used to form a perimeter edge coving up to a height of 50 mm. Skilled applicators can also use it to repair stair treads and fix expansion joint edges.

Although Vetotop ES459 is impervious at a thickness of 3 mm in constantly wet operations areas or where a high degree of cleanliness is required, you can seal Vetotop ES459 with Vetotop EC498 (Vetotop ES459 must be at least 3 days old. Rub down high spots such as trowel marks).

Clean all tools and equipment immediately after use with Vetonit Solvent XX300.
