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 means such as grinding or blasting to provide a sound, well-profiled surface. All necessary repairs should be made beforehand using Vetotop US172. New concrete floors should be at least 5 days old and visibly dry without standing water on top. Cut the grooves according to the floor area to control shrinkage. Contact Saveto for any additional information.

Apply a 1 mm scratch layer of Vetotop UL171 before the actual application. 

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). 

Then, apply the primer immediately to the prepared substrate using a stiff brush and/or a roller. Scrub the primer well into the substrate to ensure full coverage. Do over-apply or allow ‘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 (when the first coat is directly absorbed into the substrate. In general, observing the minimum overcoating times is recommended).

Vetotop UL171 is supplied in three pre-weighed packs (base, hardener, and aggregate) which are ready to use on-site. Mixing partial quantities will impair both the performance and the finished floor’s appearance. Mix using a forced-action mixer or a heavy-duty mobile mixer fitted with a jiffy-type mixing paddle. The capacity and type of the equipment used should be approved by Saveto. 

Mix the components in a suitably sized mixing container. Stir the base and hardener individually, then empty them into the mixing vessel (remember to scrap the edges) and mix for 30 seconds. Then, slowly, add the content of the graded aggregate pack and mix for another 3 minutes until the mix is completely homogeneous.

To achieve the best flow and leveling qualities, apply the product at a temperature between 25 and 30ºC. However, it can be applied at temperatures between 20 and 32ºC. 

Make sure you have enough workers and ready materials to mix and apply in a continuous process for each floor area. 

Once mixed, use the material within its pot life. Pour the material onto the prepared and primed substrate as soon as mixing is complete. Spread the material evenly and slowly to the required thickness using a notched trowel or a gauged spreader. Do not overwork the resin.

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 (This should be done before the product sets).

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

Remove Vetoprime UP170 and Vetotop UL171 from tools and equipment with water immediately after use. Remove hardened material mechanically
