Sikafloor®-235 ESD may only be used by experienced professionals. Sikafloor 235 ESD is a decorative and protective dissipative self-smoothing system for concrete or cement screeds with normal up to medium heavy wear. Particularly suitable for areas with requirements for a low electrostatic charge (Body-voltage) and dissipative surface. Typical applications include industries that process, assemble, install, package, test or transport, such as clean room, pharmaceutical, automotive industries etc.
Concrete substrates must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2. The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. If in doubt, apply a test area first. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface levelling can be carried out using appropriate products from the Sikafloor®, SikaDur® and SikaGard® range of materials.
Wearing course smooth:
Sikafloor®-235 ESD is poured, spread evenly by means of a serrated trowel e.g. Large-Surface Scraper No. 656, Toothed blades No. 25. After spreading the material evenly, turn the serrated trowel and smooth the surface in order to achieve an aesthetically higher grade of finish. Roll immediately (within max. 10 minutes of application) in two directions with a steel spiked roller to ensure even thickness and to remove entrapped air. To obtain the highest level of aesthetic finish, spike roll in two directions at a 90 degree angle, passing only once in each direction.
Wearing course textured:
Sikafloor®-235 ESD (+ Thinner C & Extender T) is applied with a serrated trowel e.g. Trowel No. 999 or Adhesive Spreader No.777, Toothed blades No. 23 = A3’and then back-rolled (crosswise) with a textured roller.
Sika Sikafloor 235 ESD is used within the following Sika systems:

|Type:||Epoxy Electrostatic Resin|
|Stock Colours:||Only tints|
Almost unlimited choice of colour shades. Please note, bespoke tints are non refundable / exchangable.
Due to the nature of carbon fibres providing the conductivity, it is not possible to achieve exact colour matching. With very bright colours (such as yellow and orange), this effect is increased. Under direct sun light there may be some variations and colour variation, this has no influence on the function and performance of the coating.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
