Evaporation time is dependent on the substrate, the weather and the amount of primer applied. Let the material dry sufficiently until the surface is no longer tacky (touch-dry).
Consumption
~ 100–150 g/m2 per layer.
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.
SUBSTRATE QUALITY
The substrate must be sound, clean, homogeneous, free from all contaminants such as oils and grease, dust and loose or friable particles, cement laitance and other poorly adhering materials.
SUBSTRATE PREPARATION
IMPORTANT
Exposing blow holes and voids
When mechanically preparing the surface, make sure to fully expose blow holes and voids.
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.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning or grinding equipment to remove cement laitance
- All dust, loose friable material must be completely removed from all surfaces before application of the Product.
- Use products from the SikaTop®, Sika MonoTop® 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.
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.
Apply the Product onto the prepared substrate by brush or roller. Ensure a continuous, pore free coat covers the substrate.
