Electrostatic Behaviour

Resistance to ground

• R^G < 10⁹ Ω (IEC 61340-4-1)
• This product fulfils the requirements of ATEX 137

Typical average resistance to ground

• R^G ≤ 10⁵ Ω to 10⁶ Ω (EN 1081)

Body voltage generation

• < 100 V (IEC 61340-4-5)

System Resistance (Person/Floor/footwear)

• < 10⁹ Ω

Note: Measurement results can be affected by ESD clothing, ambient conditions, measurement equipment, cleanliness of the floor and the test personnel.

Surface Preparation

Treatment of joints and cracks

• Construction joints and existing static surface cracks in substrate require pre-treating before full layer application. Use Sikadur or Sikafloor resins

Substrate Moisture Content

• The following test methods can be used to determine the substrate moisture content
  • Sika Tramex Meter
  • CM-measurement
  • Oven-dry-method
• The Product can be applied on substrates with a moisture content of < 4 %
• The substrate must be visibly dry with no standing water

Substrate Condition

• Cementitious substrates (concrete / screed) must be structurally sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum tensile strength of 1,5 N/mm²
• Substrates must be free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material

Mixing

For self-smoothing wearing layer:

• Mix Part A (resin) for ~10 seconds with a single paddle mixer (300–400 rpm)
• Add Part B (hardener) to Part A
• Switch to an electric double paddle mixer (300–400 rpm, > 700 W)
• While mixing Parts A + B, gradually add the required filler or aggregates
• (Optional) If necessary, gradually add the required amount of Sika Extender T (refer to Consumption)
• Mix for a further 2 minutes until a uniform mix is achieved
• To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix
• During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing

Application Notes

Important - Temporary heating

• If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters
• These produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish
• For heating, use only electric powered warm air blower systems

Important - Performing pre-trials

• Pre-trials/mock-up applications must be performed and procedures agreed with all parties before full project application

Important - Temporary moisture barrier

• Before application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures
• If moisture content is > 4 % parts by weight, Sikafloor 81 EpoCem may be applied as a Temporary Moisture Barrier (T.M.B.) system

Smooth Wearing Layer:

Tools required - Large-Surface Scraper, Toothed Blades

Procedure

• Pour the mixed Product onto the substrate. Note: The consumption is specified in Application Information (see Product Data Sheet)
• Apply the Product evenly over the surface with a serrated trowel
• To achieve a smooth finish, smooth the surface with the flat side of a trowel
• Back roll the surface in two directions at right angles with a steel spike roller

Textured Wearing Layer:

Tools required - Trowel, adhesive spreader, Toothed blades

Procedure

• Pour the mixed Product onto the substrate. Note: The consumption is specified in Application Information (see Product Data Sheet)
• Apply the Product evenly over the surface with a serrated trowel
• Back roll the surface in two directions at right angles with a textured roller

Cleaning of tools

• Clean all tools and application equipment with Sika Thinner C immediately after use
• Hardened material can only be removed mechanically

Limitations

• IMPORTANT: Indentations - Under certain conditions, underfloor heating or high ambient temperatures combined with high point loading may lead to indentations in the resin
• IMPORTANT: No simultaneous mechanical and chemical strain - While the product is exposed to temperatures up to +60 °C, do not also subject it to chemical and/or mechanical strain, as it may cause damage to the product
