Vetotop EC498

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. Repair All necessary repairs 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).

Priming is not required to a good quality non-porous concrete. If the concrete surface is porous or if there is a doubt of the concrete surface quality , it is recommnend to use Vetoprime EP491 as a film forming or Vetoprime EP490 as a penetrating primer for a porous concrete.

Vetoprime EP491 should be mixed in the proportions supplied. Add the entire content of the hardener container to the base container. When thoroughly mixed, preferably using a slow speed mixer, apply the primer in a thin, continuous film using rollers or stiff brushes. Work the primer well into the concrete’s surface, taking care to avoid ponding or over application. Leave the primer to achieve a tack-free condition before applying the topcoat.

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

The application and cure temperature must be above 15°C. Lay the first coat of Vetotop EC498 using a short-haired lamb wool roller or gauged squeegee to achieve a continuous coating. Ensure to remove loose hairs on the roller before use. Apply a minimum film thickness of 200 microns per coat for the flooring system (this can be increased where specifications demand). Apply the topcoat in the same manner within 8 to 24 hours of applying the topcoat.

If the option of using antislip aggregates has been chosen, the base coat should be dressed with the chosen antislip aggregates as soon as possible after laying the base coat. The recommended procedure is to blind the base coat completely, i.e., apply excess dressing aggregate to obliterate the base coating.

Alternatively, the antislip silica particles can be broadcast in a light random dressing to provide a less dense finish, or the product can be used to obtain a smooth finish by omitting the antislip aggregates.

When the base coat has reached the initial cure (after 12 hours at 20°C or 5 hours at 35°C), the excess aggregate should be vacuum cleaned from the surface.

The top coat can now be applied by a short-haired roller or airless spray equipment. Ensure achieving a continuous film and to seal the rough surface caused by the aggregate. Apply this topcoat within 36 hours at 20°C (15 hours at 35°C) of applying the resin base coat.

Expansion joints in the existing substrate must be retained and continued through the Vetotop EC498 topping. Saveto has a range of joint sealants specifically designed for flooring (see Vetoflex PS781 and Vetoflex PS782 product data sheets).

Clean tools and equipment with Vetonit Solvent XX400 immediately after use.
