This depends on the substrate roughness and thickness of layer applied. As a guide, ~ 1.65 kg/m²/mm.

Sika MonoTop®-615 can be mixed with a low speed (<500 rpm) hand drill mixer, or for larger volumes (i.e. 2 to 3 bags, or more, at once) the use of a forced action mixer is recommended. The amount that can be mixed at a time is dependent on the type and size of mixer.

For small quantities, Sika MonoTop®-615 can also be manually mixed. Pour the minimum recommended water into a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly for at least for 3 minutes, adding additional water if necessary to adjust to the required consistency, up to the maximum specified amount.

Reinforcement Corrosion Protection Coating:
Where a reinforcement coating is required, the application of a repair mortar shall be applied wet-on-dry onto the reinforcement corrosion protection.
Refer to the System Information above for compatible Sika products and refer to the relevant Product Data Sheet for more detailed information about the reinforcement corrosion product.

Bonding Primer:
On a well prepared and roughened substrate, a bonding primer is generally not required for this product.  
When a bonding primer is required, refer to the System Information above for compatible Sika products and refer to the relevant Product Data Sheet for instructions.  
A small amount of Sika MonoTop®-615 can also be mixed slightly wetter than normal and used as a scratch coat to fill any deep cavities or pits in the base of the substrate.
Any bonding primer shall be applied on a pre-wetted substrate, and subsequent application of the scratch coat /repair mortar shall be applied wet-on-wet onto the bonding primer.

Repair Mortar Application:
Sika MonoTop®-615 can be applied either manually using traditional techniques or mechanically using wet spray equipment.
Thoroughly pre-wet the prepared substrate a recommended 2 hours before application. Keep the surface wet and do not allow to dry.
Before application remove excess water e.g. with a clean sponge. The surface shall have a dark matt appearance without glistening,
and surface pores and pits shall not contain water. When manually applying, first make a scratch coat by firmly scraping the repair mortar
over the base of the substrate surface to form a thin layer and fill any deep cavities. Ensure the whole surface to be repaired is covered by the scratch coat.
For vertical applications, build up layers from bottom to top by pressing mortar well into the repair area.
The surface can be finished according to the surface texture requirements using a float. Do not over-trowel as this may lead to surface cracking.

Finishing:
Finishing should be carried out to the required surface texture as soon as the mortar has started to stiffen.

Protect the fresh mortar immediately from premature drying for a minimum of 3 days using an appropriate curing method e.g. curing compound, moist geotextile membrane, polythene sheet, etc.

Curing compounds shall not be used when they could adversely affect subsequently applied products and systems.

Reference shall also be made to BS EN1504-10 for specific requirements.

Clean all tools and application equipment with water
immediately after use. Hardened material can only be
mechanically removed.
