SAMAISĪŠANA
Sika MonoTop®-2002 Universal 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. 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 adding additional water if necessary, within the mixing time to the maximum specified amount and adjust to the required consistency.
IESTRĀDE
Bonding Primer:
On a well prepared and roughened substrate a bonding primer is generally not required for this product. When a bonding primer is required, refer to the System Information above for compatible Sika products and refer to the relevant Product Data Sheet for instructions. All small amount of Sika MonoTop®-2002 Universal can also be mixed slightly wetter than normal and used as a scratch coat to promote adhesion of the repair mortar to the substrate. Any bonding primer shall be applied on a pre-wet substrate and subsequent application of the repair mortar shall be applied wet on wet with the bonding primer.
Reinforcement Corrosion Protection:
Where a reinforcement coating is required the application of a repair mortar shall be applied wet on dry with the reinforcement corrosion protection. Refer to the System Information above for compatible Sika products and refer to the relevant Product Data Sheet for more detailed information about the reinforcement corrosion product. Sika MonoTop®-2002 Universal can be applied either manually using traditional techniques or mechanically using wet spray equipment. 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. When manually applying first make a scratch coat by firmly scrapping the repair mortar over the substrate surface to form a thin layer and fill any pores or pits in the surface. Ensure the whole surface to be repaired is covered by the scratch coat. Build up layers from bottom to top by pressing mortar well into the repair area. The surface can be finished according to the requirements using a float while wet or with a relevant rough-cast tool as soon as the mortar has started to stiffen.
APSTRĀDE CIETĒŠANAS LAIKĀ
Protect the fresh mortar immediately from premature drying using an appropriate curing method e.g.curing compound, moist geotextile membrane, polyethylene sheet etc. Curing compounds must not be used when they could adversely affect subsequently applied products and systems
DARBARĪKU TĪRĪŠANA
Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
