Surface preparation

Plaster, Concrete, Brick and Masonry
Plaster should be dry and thoroughly cured. Any soft, dusty layer on new plaster should be removed. Render and concrete should preferably be dry and at least four weeks old and free of any soft laitance and contaminants. Thoroughly remove all loose material by wire brushing. General dirt etc. should be removed with Watco Bio D. The surface must be absolutely free of all contamination before the product is applied. Cracks in render and concrete may be filled using Watco Concrex.

Vertical Surfaces with Algae or Fungal Growth
Remove all growths by wire brushing. Apply a suitable fungicide solution following the manufacturer’s instructions. Painted Surfaces: Remove all defective paint and sand to create a key. Damp Surfaces: To ensure penetration, the surface should be as dry as possible, clean, sound and free of any loose material. 


Each pack consists of a container of Resin and a larger container of Curing Agent, all in a tall outer tin. Stir and empty the complete contents of each tin into the outer tin and continue stirring with a wide bladed tool very thoroughly until an even colour and texture is obtained. Alternatively use a Watco Paint Mixer. Once the product has been mixed it has a usable pot life of 1-2 hours at 20°C. At higher ambient temperatures the pot life will be reduced.


If appearance is critical we recommend the application of a small trial area first.

Best results are obtained in warm conditions (preferably at a minimum 15°C) with good ventilation. Do not apply below 10°C. Apply using a short pile type roller (not foam). A short pile radiator roller can be used for working around obstructions. Only use a brush for ‘cutting in’ since a more even finish is achieved using a roller. Avoid applying too thickly to prevent ‘curtaining’. Do not re-work areas of coating or attempt to even out areas which are starting to cure and showing differences in colour. Any colour differences should disappear when the coating is thoroughly cured. The second coat should be applied within 24 hours. On high suction backgrounds or very damp surfaces three or more coats may be required. The first coat on damp surfaces may appear streaky. This effect will reduce after curing. In exceptional temperature conditions advice should be obtained from Watco’s Technical Department.

Store at a minimum temperature of 15-25ºC for 8 hours prior to use. Do not allow the product to freeze.

Useful information

Our Hygienic Wall Coating needs to be applied in two coats. It’s supplied as a tin of resin and a tin of curing agent. And when you mix the contents of the two tins together, it starts a reaction which causes the paint to cure.

If you’re painting an area of 30m², you’ll need four 3L tins (because, once mixed, a tin won't keep for the second coat).

Here’s how we work it out:

  • Area to be painted: 30m² with two coats (we recommend two coats for the best result)
  • Tins needed: 4 x 3L
  • Why: Use 2 x 3L for the first coat; and the same again for the second

Our Coverage Calculator works this out for you – that way you know you’re buying exactly the paint you need and can use, without unnecessary waste.
