Preparing and cleaning the surface

1. Carefully clean the surface, making sure to remove any dust or dirt present.

2. Never apply CONCRETE HARDENER to wet surfaces. The product can be used on slightly
damp surfaces; nonetheless, please ensure that the surface to be treated is as dry as possible.

3. Apply CONCRETE HARDENER to surfaces with a temperature of between +5 and +40°C

4. Any adjacent surfaces not being treated with the product must be protected.

Application to aid polishing

CONCRETE HARDENER must be used as part of the mechanical polishing process on surfaces
previously sanded with 200/400 grain. To speed up the whole process, it is advisable for the
preliminary sanding process to be carried out dry so as not to wait for the surface to dry before
applying CONCRETE HARDENER. In the event this preliminary sanding operation is carried out with water, it is necessary to wait at least 24-48 hours before applying CONCRETE HARDENER or to cut out this waiting time, it is possible to apply CONCRETE HARDENER before commencing with the first mechanical polishing grains; this will drastically limit the amount of water absorbed by the surface, allowing immediate drying for the following steps before the reapplication of CONCRETE HARDENER.

Once CONCRETE HARDENER has been applied to a dry surface, it is possible to continue with
the polishing process, starting with the next grain size from the one used before applying
CONCRETE HARDENER. This second part of the polishing process must be carried out with
water. Thanks to CONCRETE HARDENER, the surface can be treated with finishing chemical
polishes after the 800 grain size has been used, which may already correspond to mechanical
polishing carried out with particularly fine grain (1500-3000)

5. On dried, cleaned and sanded material, apply an abundant, even layer of product using a
lambswool applicator, roller, brush or airless applicator or any other tools for the purpose. Make sure to create an even layer to cover the whole surface being treated. In case of application to especially absorbent surfaces, proceed to apply a second coat of product, following the same
method, at around 1-2 hours from the first.

6. Considering that the resulting surface will need further mechanical polishing, it is not
necessary to concentrate on any residual products, which will be removed in successive stages.

7. Proceed with the next level of polishing grain no less than 4 hours after applying CONCRETE
HARDENER. We recommend in any case to proceed on the following day to allow the CONCRETE HARDENER to spread and cure completely.

The application of CONCRETE HARDENER to aid the mechanical sanding process is also possible before laying slabs or tiles.
