Consumption depends on the roughness and absorbency of the substrate.

This figure is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

25 kg of powder yields approximately 14,85 litres of mortar

Substrate preparation

• Mechanical hand held tools
• High / ultra-high pressure water blasting system

Steel reinforcement

• Abrasive blast cleaning system
• High pressure water blasting system

Mixing

• Small quantities - low speed electric single or double paddle mixer (<500 rpm). Mixing Container.
• Large quantities or machine application - suitable forced action mixer

Application

• Hand applied – Plasterers hawk, trowel
• Wet Spray - All in one mixing and spraying machine or separate spraying machine and all associated ancillary equipment to suit application volumes

Finishing

• Trowel ( Steel, PVC or wooden),sponge
• Also refer to  Site Handbook ‘Repair of Concrete Structures – Patch Repair and Spray Applications’

Hand applied or Wet Spray Application

Pour the minimum recommended clean water quantity in 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 the maximum specified amount and adjust to the required consistency to achieve a smooth consistent mix. The consistency must be checked after every mix.

Reinforcement Corrosion Protection Coating

Where a reinforcement coating is required, apply to the whole exposed circumference Sika MonoTop®-1010 or SikaTop® Armatec® 110 EpoCem® (Refer to Product Data Sheet(s)).

Bonding Primer

On a well prepared and roughened substrate or for a sprayed application, a bonding primer is generally not required. When a bonding primer is required to achieve the required adhesion values, use Sika MonoTop®-1010 or SikaTop® Armatec® 110 EpoCem® (Refer to respective Product Data Sheets). Apply repair mortar onto bonding primer “wet on wet”.

Levelling Mortar

Hand Application

Thoroughly pre-wet the prepared substrate (2 hours recommended) 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 must appear a dark matt appearance without shining and surface pores and cavities must not contain water.

When manually applying by hand, first make a scratch coat by firmly scraping the mortar over the substrate surface to form a thin layer and fill any pores or cavities in the surface. Ensure the whole surface to be repaired is covered by the scratch coat. The mortar must be applied onto the wet scratch coat between the minimum and maximum layer thicknesses without the formation of voids.

Sprayed Application - Wet Spray

The wet mixed Sika MonoTop®-3020 must be placed into the spraying equipment and applied onto the pre-wetted substrate (pre-wet procedure as hand application) between the minimum and maximum layer thicknesses without the formation of voids. Where layers are to be built up, to prevent sagging or slumping, each layer should be allowed to stiffen before applying subsequent layers “wet on wet”.

Surface finishing

Finishing for all types of application must be carried out to the required surface texture using suitable finishing tools as soon as the mortar has started to stiffen

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. curing compound, moist geotextile membrane, polythene sheet, etc.

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

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