MIXING
Sika MonoTop®-615 can be mixed with a low speed
(<500 rpm) hand drill mixer or for machine application,
using a force action mixer 2 to 3 bags or more at once
depending the type and size of mixer.
For small quantities, Sika MonoTop®-615 can also be manually mixed
Pour the minimum recommended water in a suitable
mixing container. While stirring slowly, add the
powder to the water and mix thoroughly at least for 3
minutes adding additional water if necessary to the
maximum specified amount and adjust to the required
consistency.
APPLICATION
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 productsand refer to the relevant Product Data Sheet for instructions.
A small amount of Sika MonoTop®-612 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-wet substrate and subsequent application of the scratch coat /repair mortar
shall be applied wet on wet onto the bonding primer.
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 appear 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 mortar has started to stiffen.
CURING TREATMENT
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.
CLEANING OF TOOLS
Clean all tools and application equipment with water
immediately after use. Hardened material can only be
mechanically removed.
