Vetotop EL699 - AE

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 EL699 should be primed with Vetoprime EP691 (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 EL699 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 material is obtained.

Ensure sufficient labor and materials to make the mixing and subsequent application process a continuous one for any given, independent floor area. 

Once mixed, pour the material immediately on the floor and spread it before aggregate settlement occurs. Pour the material onto the prepared and primed substrate as soon as mixing is complete. 

Spread it to the required thickness evenly and slowly using a notched trowel or a gauged spreader. Do not overwork the resin. spreading evenly and slowly. 

After laying, roll the material immediately using a spiked nylon roller to remove slight trowel marks and assist air release. Use 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 (this should be done before the product sets).

Follow all existing expansion or movement joints along the new floor surface.

Remove Vetoprime EP691 and Vetotop EL699 from tools and equipment with Vetonit Solvent XX600 immediately after use. Remove hardened material mechanically.
