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:

~ 300 µH₂O

For brush application: 210 ml per 1 kg of Sika MonoTop®-910 N
For spraying application: 200 ml per 1 kg of Sika MonoTop®-910 N

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

Apply concrete repair wet on wet with bonding primer

Apply concrete repair wet on dry reinforcement corrosion protection

As 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.
As Reinforcement Corrosion Protection - As a guide, ~2.0 kg of powder per m² per 1mm layer thickness

4 kg of powder yields approximately 2.25 litres

Sika MonoTop®-910 N can be mixed with a low speed (<500 rpm) hand drill mixer or by hand for a small quantity.
Pour the recommended water in a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly at least for 3 minutes.

As Bonding Primer
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. Using a suitably clean brush, roller or suitable spraying equipment cover the substrate in a thin layer filling all unevenness, pits and pores.
As Reinforcement Corrosion Protection
Using a suitably clean brush or spraying equipment apply a first layer to cover the reinforcement bars approximately 1 mm thick. When first coat is hard to the finger nail apply second layer approximately 1 mm thick. If using a spray method protect substrate from excessive over-spray wiping away any concentrated accumulation and wait until completely dry before to apply repair mortar.

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

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