0.4 mm

Sika MonoTop®-3020 is the optional smoothing coat of the Sika® repair system. It is applied on top of the concrete repair mortar.

4.6–4.7 L water for 25 kg powder

Pot life depends on temperature

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

As a guide, depending on weather conditions overcoat 3 days after application (2 days curing + 1 day drying) with the Sikagard® range of protective coatings. For other emulsion paints, refer to the relevant manufacturer’s product information.

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

• Industrial vacuuming equipment

STEEL REINFORCEMENT EQUIPMENT

• Abrasive blast cleaning equipment

• High-pressure water blasting equipment

MIXING EQUIPMENT

• Clean mixing containers

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

• For 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

CURING EQUIPMENT

• Polyethylene sheeting

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.

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 without standing water (saturated surface dry).

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.

ON-SITE CONDITIONS

• In draughty areas, open spaces, at temperatures less than +10 °C or in very dry climates, early plastic shrinkage cracks may occur due to rapid moisture loss. Confirm substrate moisture content, product, substrate and air temperatures prior to application.

• In hot weather, store bags in a cool environment and use cold mixing water to assist with controlling the exothermic reaction.

• In cold weather, store bags in a warm environment and use warm mixing water to assist with achieving strength gain.

SMOOTHING COAT - MANUAL APPLICATION

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Apply a thin layer of smoothing coat Product over the complete substrate surface to fill surface pores or cavities.
3. Apply more Product wet on wet, observing the minimum and maximum layer thicknesses.

FILLING BLOWHOLES

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Rub the smoothing coat Product directly into the pores using a trowel or jute cloth.
3. Remove all excess material as soon as possible.

SMOOTHING COAT - WET SPRAY APPLICATION

1. Remove excess water from within surface pores and cavities.
2. Spray-apply a thin contact layer of smoothing coat Product over the complete substrate surface to fill surface pores or cavities.
3. Spray-apply more Product wet on wet, observing the minimum and maximum layer thicknesses. Spray with enough pressure to ensure good adhesion.

SURFACE FINISHING BY HAND

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.
