Tools & cleaning


Mixer, gauge rake, smoother, screen, protective gloves.


Clean tools in water after use.


Preparation of base surface


The base surface must be resistant, sound, solid, clean, dry and free of humidity. Use Harmony neutral cleaning agent for any cleaning required (to remove grease, oil or soiling).

On a porous surface, apply Harmony Primer.


On tiling, apply Harmony Epoxy Resin.


For more information on primers, see data sheet on Primer and/or Epoxy Primer.




Any existing expansion joints, bay joints and edge joints in screeds or slabs should be observed. Specifically, this is essential in the case of heated floors.


Avoid any exposure to wind and sunlight during application and drying.

Close shutters or black out windows, and eliminate any draughts.


Do not forget to fit PermaPro edging strip to separate walls from the flooring.


For each 25 kg bag of Harmony Levelling Compound, mix with 6 litres of water for a maximum of 3 minutes, then allow the mixture to rest for 1 minute until any bubbles have dispersed.


In order to eliminate any lumps, use the PermaPro screen to screen the mixture, then transfer to another bucket.


Apply Harmony Smooth Concrete [sic] in a 4 mm layer using the PermaPro gauge rake.


If the PermaPro screen has not been used, the PermaPro spiked roller should be applied to ensure effective load distribution and the elimination of any lumps. Smooth the surface using the PermaPro Flemish trowel.


Do not attempt to mix fresh Harmony Levelling Compound with water once the product has thickened.
