Facade coating JSP 0.5

Product description

The Fescon Facade Coating JSP is a polymer-modified cement-based coloured thin-layer plaster that contains additives improving its weather resistance and reducing capillary water absorption. Suitable for spray and manual application. The maximum grain size is 0.5 mm.


  • easy to use
  • good grip on the base
  • good workability characteristics
  • separate adhesives not required
  • spray-applied
  • chloride-free
  • excellent weather resistance
  • breathable


  • concrete and brick facades
  • surfaces treated with cement-based levelling or finishing plasters

N.B. Not suitable over organic paint or an elastic joint.

The product is suitable for use on sites with a Nordic Swan Ecolabel.

Check the water requirement of the coating from the bag. Add the dry material to the water and mix with a concrete mixer for around ten minutes. With a power mixer or a drill paddle, around one to two minutes of mixing is sufficient. Allow the coating to stand for around ten minutes and mix it again for a short while. Find the correct consistency at this stage by gradually adding the rest of the water. We do not recommend adding all of the water right at the start. The finished coating remains workable for around two hours.

Remove old coatings and paint, for example by water sand blasting. Also roughen any new concrete surfaces by water sand blasting. Clean the surfaces of dust with a pressure washer. Repair any damaged concrete. The patch surfaces must be left as coarse as possible. Allow the patches to harden for at least one or two days before coating. If the base has dried up, wet it until it is darker in colour. The best time to wet the surface is the previous night. Before starting work, apply a test coating to ensure the structure and tint. The tint is affected by, for example, the absorption characteristics of the base, the consistency of the mass, the coarseness of the surface, and naturally the sprayer itself (nozzle size and air volume), and the spraying method used.

The Fescon Facade Coating is sprayed using a levelling spray or a funnel top sprayer. It can also be spread manually using a steel trowel or a brush. Spray the first layer to a thickness of 1-2 mm and the second to a thickness of 1 mm. The first layer must be allowed to harden for at least one day before the next spraying. Spray the last layer using mass that is as dry as possible in good weather conditions. Dark colours require greater care than light colours when spraying. We recommend spraying contiguous surfaces at the same time. You should "hide" the working seams in corners, expansion joints or, for instance, behind drainpipes. There may be some differences in the tint of different manufacturing batches, so we recommend ordering the required amount of coating all at once. With a plaster spray, the spraying distance is over 1 m, and with a funnel top sprayer, around 0.6 m. Spray using circular motions perpendicularly to the surface. The water-soluble salts in the cement and the salts formed during the hardening of the lime may rise to the surface with moisture and appear as efflorescence. Heavy rain soon after the coating, internal moisture in the structure, thermal leakage and insufficient ventilation cause efflorescence. The risk can be reduced by protecting the fresh coating from rain. For the same reason, the new facade should be allowed to dry for at least one heating season before coating.

In very dry conditions, the coated area must be protected with a plastic film or light spraying of water (the water must not flow) for at least one to three days.
When the temperature is:
+ 20°C, protect the fresh coating from rain and strong sunlight for one day
+ 10°C, protect the fresh coating from rain for three days
+ 5°C, protect the fresh coating from rain for seven days

A dirty surface treated with Facade Coating can be cleaned with a pressure washer. Remove any damaged spots and repair the holes. No water should remain on the base after cleaning. Facade Coating or Stone Colour S paint can be used for recoating. The work instructions for the product used must be followed during coating and painting work. One treatment is normally sufficient for a cleaned, undamaged surface. Two or more treatments are needed for damaged areas from where the coating has been removed or holes have been patched.
