Substrate requirements
Only concrete screeds and bonded screeds primed with Crete TF 60 or Crete FP are permitted substrates.
The substrate must be load-bearing, dimensionally stable, solid, free of loose parts, dust, oils, grease, rubber marks and any other substances that could interfere with adhesion. It must be primed so as to remove all surface pores.
The tensile strength of the surface of the substrate must be at least 1.5 N/mm² on average (smallest individual value of at least 1.0 N/mm²), and the compressive strength must be at least 25 N/mm².
Concrete max. 6 m% moisture Cement screed max. 6 m% moisture

Application
-
As a general principle, higher temperatures will reduce and lower temperatures will increase the times stated.
-
Working tools / cleaning
-
Layer thickness trowel, gauge rake, spiked roller, mixer, compulsory mixer if necessary
-
More detailed information can be found in the Remmers Tool Programme.
Clean tools, equipment and splashed material immediately while fresh with V 101.
Take suitable protective and waste disposal measures when cleaning.
-
Storage / shelf life
-
If stored in unopened original containers in a cool, dry place and protected from frost, at least 6 months for component A, at least 12 months for component B and C and at least 18 months for component D.

Application examples
-
Coating
Pour the material on the prepared surface and spread using a suitable tool, such as a layer thickness trowel / gauge rake.
Immediately roll a spiked roller slowly over the surface (no more than one crosswise operation).
12 - 18 kg/m²
-
Base layer for blinded coatings
Pour the material on the prepared surface and spread using a suitable tool, such as a layer thickness trowel / gauge rake.
Immediately roll a spiked roller slowly over the surface (no more than one crosswise operation).
Immediately scatter an excess of suitable blinding material onto the fresh base layer.
Remove any loose, excess material after hardening.

General information
-
Unless otherwise specified, all of the values and application rates given above have been determined under laboratory conditions (20 °C) using standard colours. Slight deviations from these values may arise if the product is worked with on site.
When coating continuous surfaces, only use materials with the same batch number as slight differences in colour, gloss and texture may occur.
The resulting surface texture is strongly influenced by the conditions on site and the application method. Therefore, surface texture is not covered by product liability.
To delimit the coated surface, sufficient anchoring cuts must be made (width and depth of the cuts is twice the thickness of the coating system).
PU concretes in general are functional floor coverings with low requirements with regard to appearance and are generally not colour-fast.
Even if the flooring is correctly installed, differences in colour, marks made during application, streaking and slight formation of pools cannot be excluded.
Due to the short reaction time, the coating operation must be well planned and prepared.
Low thickness and low temperature can affect the visual effect of the finished surface.
Abrasive mechanical loads leave traces of wear.
Exposure to vehicles with metal or polyamide tyres as well as dynamic concentrated loads can cause faster wearing of the coating.
Blinded coatings must be applied immediately to ensure the proper bonding of the blinding material.
In case of repairs on the surface or working up to existing surfaces, there will be a visible transition in appearance and texture.
The resistance to chemical substances must be assessed with regard to the temperature of the medium (see chemical resistance list).
Anti-slip floors naturally require more cleaning effort than smooth surfaces. Therefore, the use of cleaning machines with soft brushes is recommended.
