Readings may vary, depending on ambient conditions (i.e. temperature, humidity) and measurement equipment.

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.

Refer to the individual primer Product Data Sheet

Before overcoating the Product, allow:

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

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.

MIXING

• Electric single paddle mixer (300 to 400 rpm)

APPLICATION

• Short-pile nylon roller

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.

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.

1. Fully expose blow holes and voids during surface preparation to identify the required repairs.

1. Remove weak cementitious substrates.
2. Prepare cementitious substrates mechanically using abrasive blast cleaning, abrasive planing or scarifying equipment to remove cement laitance.
3. Before applying thin layer resins, remove high spots by grinding.
4. Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
5. 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.

1. Mix Part A (resin) until the coloured pigment is dispersed and a uniform colour is achieved.
2. Add Part B (hardener) to Part A.
3. IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~2 minutes until a uniformly coloured mix is achieved.
4. To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
5. 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.

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.

1. 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.

1. Do not use self-adhesive copper tapes to form conductive grids across the floor.
2. Only use the earthing points contained in the Sikafloor® Conductive Set.
3. Earthing points must be marked and covered using a rubber mat with a resistance of > 1 MΩ.
4. 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.

1. Pour the mixed Product onto the surface. For consumption, refer to Application Information.
2. Apply the Product evenly over the surface with a short-piled roller.
3. Back-roll the surface in two directions at right angles. Note Ensure that a continuous, pore free-coat covers the substrate.
4. 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.
