Instructions for use

Design Criteria

Vetotop UC371 is designed to be a hard-wearing thin coat application on cementitious or metal substrates and a top coat over epoxy and aromatic urethane coatings thicknesses between 70 and 100 microns. The product is used for internal and external applications. The applied product will be resistant to water as well as a wide range of chemicals.

Mixing Vetotop UC371
In a separate mixing vessel, use a slow speed mixer to mix the base, hardener for 3 minutes. Mix these components in the quantities supplied, taking care to ensure all containers are scraped clean. Do not add solvent thinners at any time.

Apply Vetotop UC371 by roller. The application should be at a rate of 6.6 m2/liter per coat.
The application should not be carried out when humidity exceeds 75%, or when the surface temperature to be coated less than 3°C above the dew point.
Vetotop UC371 can be applied as a single coat or multi-coat sandwich system incorporating Vetograin products to give a slip-resistant finish.
For more information, please refer to Vetograin Technical Data Sheet.

Expansion Joints
Expansion joints in the existing substrate must be retained and continued through the Vetotop UC371 topping. Saveto has a range of joint sealants specifically designed for flooring (see Vetoflex PU781 and Vetoflex PS782 product data sheets).


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

Surface Preparation

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. All necessary repairs should be made 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).

It’s mandatory to apply a penetrating primer Vetoprime EP490 on the porous substrates before applying Vetotop UC371.
