Application steps

MIXING

Pour the water in the correct proportion into a suitable mixing container. While stirring slowly, add Sika MonoTop®-610 MY to the water. Hand mix thoroughly with a spatula to a thick “slurry” consistency. Always ensure that there are no lumps in the mix. If a mix has thickened due to delayed application, do not dilute further with water. This mix should be discarded.

APPLICATION

Concrete

Use a brush to apply a coat of freshly mixed slurry of Sika MonoTop®-610 MY on to the substrate, covering it completely. This is followed immediately with a “wet-on-wet” application of the patch repair mortar (e.g. Sika MonoTop®-R, Sika MonoTop®-R 40, Sika MonoTop®-412 MY or Sika MonoTop®-615 SD).

Steel reinforcement

Use a brush to apply 2 coats of freshly mixed slurry of Sika MonoTop®-610 MY onto the prepared steel reinforcement prior to the application of the patch repair mortar. Precaution should be taken to ensure that the back of the reinforcement is also coated with Sika MonoTop®-610 MY.

CLEANING OF EQUIPMENT

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