• Qld Roads (TMR) Section 5. Registered and Conforming Products. Part 5.34 Repair Mortars

Portland cement, silica fume, re-dispersible polymer powder, selected aggregates and additives

12 months

Store properly in undamaged original sealed packaging, in dry cool conditions between +5 °C and +35.

Fresh mortar density ~1.9 kg/l

Sika MonoTop®-910 N is part of the range of Sika mortars complying with the relevant part of European Standard EN 1504 and comprising of:

For large volume: 2.0 - 2.2 litres of water per 10 kg bag

                                 4.0 - 4.4 litres of water per 20 kg bag
For small volume: 4 part of powder to 1 part of water by volume

As bonding primer - sufficient to coat the concrete surface in a thin layer filling unevenness, pores and pits

As reinforcement corrosion protection - 2 mm minimum thickness

+5°C minimum; +30°C maximum

+5°C minimum; +30°C maximum

~90 to 120 minutes at +20°C

~ 5.5 hours

~ 7.5 hours

Apply concrete repair wet on wet with bonding primer

Apply concrete repair wet on dry reinforcement corrosion protection

Bonding Primer:

This depends on the substrate roughness and thickness of layer applied. As a guide, ~1.5 – 2.0 kg of powder per m² per mm thick.
Reinforcement Corrosion Protection:
As a guide, ~2.0 kg of powder per m2 for 1mm layer thickness (in total min 2 layers)

Sika MonoTop®-910 N can be mixed with a low speed (<500 rpm) electric drill mixer. In small quantity, Sika MonoTop®-910 N can also be mixed by volume in a mixing ratio of 4 part of powder by 1 part of water.
Pour the water in the correct proportion into a suitable mixing container. While stirring slowly, add the powder to the water. Mixed thoroughly to the required consistency (brushable non-dripping consistency).

As a bonding primer
Apply by brush, roller or suitable spraying equipment to the prepared (pre-wetted) substrate. To achieve good bond, Sika® MonoTop®-910 N must be applied well into the substrate, filling all unevenness.
Subsequent repair mortar must be applied while the bonding primer is still wet.
As reinforcement protection
Apply first layer approx. 1.0 mm thick, using medium hard brush or spray gun to cleaned reinforcement. When first coat is hard to the finger nail, for guidance~4 to 5 hours at 20°C, apply second layer approximately 1.0 mm thick.

As reinforcement corrosion protection - protect the fresh mortar immediately from premature drying and contamination using an appropriate curing method.

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