This figure 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

Important: The consistency must be checked after every mix.

  1. Pour the minimum recommended clean water quantity in a suitable mixing container.
  2. While stirring slowly, add the full bag of powder continuously to the water until a uniform lump free consistency has been achieved.
  3. Continue mixing for 3 minutes.
APPLICATION

Important: Thoroughly saturate the prepared substrate before application with clean water to achieve a saturated surface dry (SSD) surface. Before application remove excess water, e.g. with a clean sponge.

Important: The first layer must be applied by stiff bristled brush.

Note: The product can be applied with a stiff bristled brush, spatula or smooth trowel in 2 or 3 layers.

  1. Apply mixed material onto the prepared pre-wet substrate by slurry brush by working the slurry well into the substrate and without the formation of voids.
  2. Apply the following layers at right angles to each other when the previous layer has sufficiently dried (~4–6 hours) and no later than 12 hours.
CURING TREATMENT
  • Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. water spray, moist geotextile membrane, polyethylene sheet, etc.
  • Cure for at least 7 days after application.
CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use.

Hardened material can only be mechanically removed.
