All surfaces should be dry and free from contamination, such as oil, grease, loose particles, decayed matter, moss algal growth, laitance, and all traces of mold release oils and curing compounds. This is best achieved by lightly grit-blasting the surface. Where moss, algae, or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with a Saveto repair system.
 

All surfaces receiving Vetotop UL170 should be primed with Vetoprime EP491, 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 3 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. Still, 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 a minimum over-coating time.

Vetotop UL170 is supplied in two pre-weighed packs (base and hardener), 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. Mixing should be carried out 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 vessel. Stir the base and hardener components individually, then empty them into the mixing vessel scrapping the edges and mix for 3-4 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, use the material within its specified pot life. Pour the material should onto the prepared and primed substrate as soon as mixing is complete. Spread it to the required thickness using a notched trowel or a gauged spreader, taking care not to 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 for rolling. 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 but should be before the setting of the product.

Remove Vetotop UL170 product from tools, equipment, and mixers with Vetonit Solvent XX400 immediately after use.
