Synthetic rubber,solvent-dispersed and resin based primer

18 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Protect from direct sunlight and frost. Always refer to the packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

-20 °C

(900 ± 100) mPa·s

Beware of condensation. The substrate and uncured applied product must be at least +3 °C above the 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.

No rising moisture (ASTM D4263, polyethylene sheet)

20 minutes at +20 °C

Note: Evaporation time is dependent on the substrate, the weather and the amount of primer applied.

1. Let the material dry sufficiently until the surface is no longer tacky (touch-dry).

100–300 g/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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum tensile adhesion strength of 1,5 N/mm2. Substrate must be even, level, clean, dry and free of all contaminants such as dirt, oil, grease and surface treatments.
Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed and repaired accordingly.

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.

Preconditions

The concrete substrate must be hardened, sound, even, level, clean, dry and free of all contaminants such as dirt, oil, grease and surface treatments.

1. Remove weak cementitious substrates.
2. Prepare cementitious substrates mechanically using abrasive blast cleaning or grinding equipment to remove cement laitance
3. Completely remove dust, loose and friable material from all surfaces before application of the Product.
4. Use products from the SikaTop®, Sika MonoTop® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.

For additional information on products for leveling and repairing defects, contact Sika® Technical Services.

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.

1. Apply the Product onto the prepared substrate by brush or roller. Note Ensure a continuous, pore free coat covers the substrate.

Clean all tools and application equipment with suitable cleaner immediately after use. Hardened or cured material can only be removed mechanically.
