Hand Application

Sika® Kanal-Reprofilierungsmörtel can be mixed with a low speed (<500 rpm) hand drill mixer or for machine application, using a force action mixer 2 to 3 bags or more at once depending the type and size of mixer. For small quantities, product can be manually mixed.

Pour the minimum recommended water in a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly for at least for 3 minutes adding additional water if necessary to the maximum specified amount and adjust to the required consistency. The consistency must be checked after every mix.

A maturing time of 5 minutes must be observed.

Thoroughly pre-wet the prepared substrate (2 hours recommended) 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 cavities shall not contain water.

When manually applying by hand, apply bonding primer. Ensure the whole surface to be repaired is covered by the suitable primer. The repair mortar shall be applied onto the wet scratch coat between the minimum and maximum layer thicknesses without the formation of voids. Where layers are to be built up, to prevent sagging or slumping, each layer should be allowed to stiffen before applying subsequent layers “wet on wet”.

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. curing compound, moist geotextile membrane, polythene sheet, etc.

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