  • Range of colours: enhances working environment.
  • Chemically resistant: protects the concrete floor surface.
  • Food grade: Solvent free and taint free formulation.
  • Hard wearing: good abrasion resistance.
  • Will withstand foot and light vehicular traffic.

Surface Preparation

Floors should normally have been placed for at least 28 days  and have a moisture content of less than 5 – 7%. Floors should be sound and free from contamination such as oil and grease, mortar and paint splashes or curing compound residues. Excessive laitance can be removed by the use of mechanical methods. Dust and other debris should then be removed by vacuum cleaning.


Priming is not normally required provided the substrate is sound, untreated and good quality nonporous concrete. If any doubts exist of the quality of the Estoprime LV.

The primer should be left to achieve a tack-free condition before applying the top coat. A second coat of primer may be required if the substrate is excessively porous.


The base and hardener components of Estogard CS50e should be thoroughly stirred before the two are mixed together. The entire contents of the hardener container should be poured into the base container and the two materials mixed thoroughly, then add the colour pot and mix for at least 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.

Expansion joints

Expansion joints in the existing substrate must be retained and continued through the Estogard CS50e topping. Estop have a range of joint sealants specifically designed for flooring, contact local Estop office for advice.


Tools and equipment should be cleaned immediately after use with Xylene. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.


  • Estogard CS50e should not be applied on to surfaces known to, or likely to suffer from, rising dampness, potential osmosis problems or have a relative humidity greater than 75% as measured in accordance with BS 8203 Appendix A, or by a Hammond concrete/mortar moisture tester type COCO.
  • ESTOP does not recommend acid etching as a method of floor preparation. If used, the method  should be approved by the project consultant.
  • In common with all epoxy materials, some slight shade changes may be experienced over the long term when placed in adverse exposure conditions. Any such change in shade is not regarded as being detrimental to performance. If movement or cracking of the substrate takes place after application then reflective cracking of the topping may occur.
  • In areas of significant thermal shock please consult Estop. Estogard CS50e should not be applied to the following substrates: – Asphalt Unmodified sand cement screeds P. V. C. tiles or sheet.
  • Estogard CS50e products should not be installed at temperatures below 10°C.
