Pot life depends on temperature

Note: Pot life will be shorter at higher temperatures. Pot life will be longer at lower temperatures.

1.9 kg powder per m² per mm

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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Select the most appropriate equipment required for the project.

SUBSTRATE PREPARATION EQUIPMENT

• Mechanical hand-held tools for spot repairs

• High- or ultra-high-pressure water blasting equipment

STEEL REINFORCEMENT EQUIPMENT

• Abrasive blast cleaning equipment

• High-pressure water blasting equipment

MIXING EQUIPMENT

• Clean mixing containers

• Small quantities: low-speed electric single or double-paddle mixer (< 500 rpm).

• Large quantities: forced action mixer

APPLICATION EQUIPMENT

• Hand-applied: plasterer's hawk, trowel

• Wet spray: All-in-one mixing and spraying machine, or separate spraying machine and all associated ancillary equipment to suit application volumes. Suitable machines include the PFT N2V, Putzmeister S 5, Wagner PC15, and Inotec inoBEAM F50.

FINISHING EQUIPMENT

• Trowel (PVC or wooden)

• Sponge

CONCRETE

1. Clean the substrate thoroughly so it is free from dust, loose material, surface contamination and material which reduces adhesion, prevents suction or wetting by the repair materials.
2. Remove delaminated, weak, damaged and deteriorated concrete and where necessary, sound concrete. Remove using mechanical hand-held tools, high or ultra-high-pressure water blasting equipment.
3. Remove sufficient concrete from around corroded reinforcement to allow cleaning, application of a corrosion protection coating (where required) and compaction of the concrete repair mortar.
4. Prepare repair surface areas in simple square or rectangular layouts to avoid shrinkage stress concentrations and cracking while the repair material cures. This can also avoid structural stress concentrations from thermal movement and loading during the service life.

STEEL REINFORCEMENT

1. Remove rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion.
2. Prepare surfaces to bright steel, Sa 2 (ISO 8501-1), using abrasive blast cleaning or high-pressure water blasting equipment.

PRE-WETTING

Sufficient saturation of the concrete substrate prior to application enables the mortar to gain its full mechanical properties.

1. Thoroughly pre-wet the prepared concrete substrate for a minimum of 2 hours before application.
2. Keep the surface wet and do not allow to dry.
3. The final pre-wetted surface must achieve a dark matt appearance (saturated surface dry).

HAND APPLIED AND WET SPRAY APPLICATION

1. Pour the minimum specified quantity of clean water into the mixing vessel.
2. Gradually add the powder to the water while stirring slowly.
3. Mix for at least for 3 minutes until a uniform, lump-free consistency is achieved.
4. If necessary, add small amounts of water, within the allowed range, to adjust consistency. Do not exceed the maximum water content.
5. Check the consistency after every mix.

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.

IMPORTANT

Risk of reduced strength gain and impaired physical properties in cold weather

Take the following measures in cold weather:

1. Store bags in a warm environment.
2. Use warm mixing water to assist with achieving strength gain and maintaining physical properties.

IMPORTANT

Risk of cracking and impaired physical properties in hot weather

Take the following measures in hot weather:

1. Store bags in a cool environment.
2. Use cold mixing water to assist with controlling the exothermic reaction to reduce cracking and to maintain physical properties.

IMPORTANT

Risk of cracking due to application in direct sun or strong winds

1. Do not apply the Product in direct sun, strong winds or both.

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 the individual Product Data Sheets.

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 the individual Product Data Sheets.

REPAIR MORTAR – MANUAL APPLICATION

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. If no bonding primer was applied, apply a thin layer of repair mortar Product over the complete substrate surface to fill surface pores or cavities.
3. Apply the repair mortar Product wet on wet, without forming voids, and observing the minimum and maximum layer thicknesses.
4. Allow each layer to slightly harden and remain wet before applying subsequent layers.

REPAIR MORTAR – WET SPRAY APPLICATION

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Place the wet mixed repair mortar into the spraying equipment.
3. Spray the repair mortar onto the pre-wetted substrate between the minimum and maximum layer thicknesses without the formation of voids.
4. Allow each layer to slightly harden and remain wet before applying subsequent layers.

SURFACE FINISHING BY HAND

IMPORTANT

Surface cracking due to rapid moisture loss

In draughty areas, open spaces, at temperatures less than +10 °C or in very dry climates, early plastic shrinkage cracks may occur.

1. Confirm substrate moisture content, product, substrate and air temperatures prior to application.

1. Allow the mortar to surface harden.
2. Surface finish to the required surface texture using a stainless steel, steel, PVC or wooden float. Do not add water.

• Cure immediately after finishing using an appropriate curing method, such as curing compound, moist geotextile membrane or polythene sheet.

• Do not use curing compounds if they could adversely affect subsequently applied products and systems.

• Protect from wind, rain, frost, and direct sunlight during curing.

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