Product temperature
Maximum | +30 °C |
Minimum | +10 °C |
Ambient air temperature
Maximum | +30 °C |
Minimum | +10 °C |
Relative air humidity
Maximum | 75 % r.h. |
Dew point
Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.
Substrate temperature
Maximum | +30 °C |
Minimum | +10 °C |
Substrate moisture content
Refer to the individual primer Product Data Sheet
Pot life
+10 °C | ~120 minutes |
+20 °C | ~90 minutes |
+30 °C | ~30 minutes |
Waiting time / Overcoating
Before overcoating the Product, allow:
Substrate temperature | Minimum | Maximum |
+10 °C | ~26 hours | ~7 days |
+20 °C | ~17 hours | ~5 days |
+30 °C | ~12 hours | ~4 days |
Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
Roller coat | ~0.08–0.1 kg/m² |
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
EQUIPMENT
MIXING
Electric single paddle mixer (300 to 400 rpm)
APPLICATION
Short-pile nylon roller
SUBSTRATE QUALITY
Cementitious substrates 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 clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
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 PREPARATION
MECHANICAL SUBSTRATE PREPARATION
IMPORTANT
Surface defects due to voids in the substrate
Voids and blow holes in the substrate will weaken the surface and damage the covering Product if not repaired during the preparation process.
- Fully expose blow holes and voids during surface preparation to identify the required repairs.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment to remove cement laitance.
- Before applying thin layer resins, remove high spots by grinding.
- Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
- Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.
Contact Sika® Technical Services for additional information on products for levelling and repairing defects.
SUBSTRATE PREPARATION OF NON-CEMENTITIOUS SUBSTRATES
For information on substrate preparation of non-cementitious substrates, contact Sika® Technical Services.
MIXING
- Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is achieved.
- Add Part B (hardener) to Part A.
- IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~2 minutes until a uniformly coloured 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
IMPORTANT
Strictly follow installation procedures
Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
IMPORTANT
Damaged finish due to heating with fossil fuel heaters
Fossil fuel heaters powered by gas, oil or paraffin produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
- For temporary heating, use only electrically powered warm air blower systems. Do not use gas, oil, paraffin or other fossil fuel heaters.
IMPORTANT
Ventilation in confined spaces
Always ensure good ventilation when applying the Product in a confined space.
IMPORTANT
Protecting the material after application
After application, protect the System from damp, condensation and direct water contact for at least 24 hours.
IMPORTANT
Earthing connections
Self-adhesive copper tapes can lead to high conductivity of the floor and non-compliance with the requirements of VDE100-610. There is no protective effect at the earthing point and ~10 cm around the earthing point.
- Do not use self-adhesive copper tapes to form conductive grids across the floor.
- Only use the earthing points contained in the Sikafloor® Conductive Set.
- Earthing points must be marked and covered using a rubber mat with a resistance of > 1 MΩ.
- Do not apply the Product on substrates with rising moisture.
Preconditions
Apply only on primed or levelled concrete and screed surfaces. IMPORTANT Do not blind the primer and only start application of the Sikafloor® conductive primer after all the primer has dried tack-free.
- Pour the mixed Product onto the surface. For consumption, refer to Application Information.
- Apply the Product evenly over the surface with a short-piled roller.
- Back-roll the surface in two directions at right angles. Note Ensure that a continuous, pore free-coat covers the substrate.
- Confirm that waiting time or overcoating time has been achieved before applying subsequent products.
Conductivity testing
Note: After curing of the Sikafloor® conductive primer and before application of the subsequent conductive wearing layers, conductivity testing of the conductive primer must be carried out.
All readings must be below 104 Ohm.
