The base surface must be resistant, sound, solid, clean, dry and free of humidity.

Use Harmony Neutral Agent or Harmony Degreaser for any cleaning required (to remove grease, oil etc).

Primer, or Primer Plus – which one to choose?

It is essential to establish whether the base surface is porous or non-porous.

To do this, apply a few drops of water to the surface concerned. If the water is absorbed, the base surface is porous. If not, it is classified as non-porous.

On a porous base surface, apply Harmony Primer, and on a non-porous base surface, apply Harmony Primer Plus.

On a wet base surface, such as a shower, sink, washbasin or, more generally, any porous base surface (plaster, timber, syporex, BA 13, etc.) which is in regular contact with water and has not been sealed beforehand, Harmony Epoxy Primer or Harmony waterproof under-sealer should be applied.

Apply glass-fibre reinforcing strips at corners.

Application of Harmony Primer

Application must be completed within a temperature range of 5° - 25°.

For anhydrite screeds, check that the humidity level is consistent with recommendations (max 2%).

Harmony Primer is supplied ready for use, and must not be diluted.

Apply uniformly to the base surface using a roller, with no excess thickness and leaving no gaps. For large surface areas, use the 250 or 500 mm PermaPro special floor nozzle.

Drying time: 30 minutes - 2 hours, depending upon the type of base surface and the ambient temperature.

Once touch dry, Harmony Primer is ready to be covered.

On a highly porous base surface, such as anhydrite screed, a second coat should be applied.
