Sika MonoTop®-910 N (adhesive mortar) = 1,5 – 2,0 kg/m²

The cementitious, polymer-modified 1-component material Sika MonoTop®-910 N is used together with the Sika MonoTop® PCC-System as corrosion protection for exposed reinforcement during concrete repairs.
Sika MonoTop®-910 N is also used as a high-tensile adhesive agent in the Sika MonoTop® PCC-System (refer to product data sheet Sika MonoTop®-910 N).
When used as SPCC, Sika MonoTop®-910 N is used as corrosion protection.

Place 90 % of the correct amount of water into a suitable clean mixing container. Slowly add complete bag of Sika MonoTop®-412 DE into the water and continiously mix for 3 minutes by using a electric low speed mortar mixer or compulsory mixer to achieve a uniform and lump free consistency. The remaining residual amount of 10 % water may be required for consistency adjustment. Do not add more water than the maximum specified.

As an adhesive mortar, Sika MonoTop®-910 N is to be brushed under pressure into the matt damp blowout spot, whereby as much material as possible must remain. Place Sika MonoTop®-412 DE in the still fresh adhesive mortar (wet in wet) and compact well. Avoid cavities. The maximum layer thickness per working process must not be exceeded. If necessary, apply Sika MonoTop®-412 DE in several layers, always in combination with adhesive mortar.

Practically all wet spraying machines, such as PFT, Putzmeister, Mader, etc. are suitable. The specifications of the machine manufacturers regarding air, water and power supply must be observed. In order to achieve the best possible spraying results (high compaction, low rebound), the spraying angle should be 90 degrees. Our recommendation of processing equipment is based on tests with a device at the time of printing the product data sheet. Since such equipment is not manufactured and distributed by Sika and may be differently configured and/or equipped and/or modified, it is necessary to conduct your own research on machine configuration, usability and testing prior to final processing. Sika assumes no liability for success or failure in the use of the equipment.

Prevent the freshly applied material from drying out too quickly, e.g. due to direct sunlight or wind; follow standard rules for the curing of cement based mortars. Freshly applied and hardened surfaces must be kept damp by covering with suitable hessian matting / plastic sheeting and / or mist spraying with water.

ZTV-ING, Part 3, Section 4 applies to curing treatment.

 
Sika MonoTop®-723 DE and Icoment®-520 mortars are used as levelling mortars in the Sika MonoTop® PCC-System (refer to product data sheets). These can be coated with the following products: Sikagard®-680 S Betoncolor, Sikagard®-675 W ElastoColor, Sikagard®-550 W Elastic, Sikagard® Wallcoat T or Sikagard®-260 WPU. The product Sika MonoTop®-910 N is used as corrosion protection and high tensile strength bonding bridge in the Sika MonoTop® PCC-System.

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