Further Information

If the surface to be painted is very porous and absorbs a lot of paint, it may be advisable to use a primer first. If you try to use the paint too thinly e.g. one litre of paint for 20 square meters, the shielding performance will decrease dramatically.

• Ready mixed paint has a limited shelf life and deteriorates whether it is used or not. This applies to all commercial paints, not just microwave screening paints. This is why we cannot offer a returns service.
• The paint is water-based, free of toxic solvents, plasticisers, film-forming agents, and it allows the walls to breathe.
• Because the paint is free of these ingredients, if you wish to wallpaper over the paint, you need to apply a coat of emulsion paint to seal the layer of carbon paint BEFORE using wallpaper paste. This should avoid any chemical reaction between the paint and the wallpaper paste.
• The YShield HSF54 and HSF63 carbon paint is very effective at reducing microwave emissions from an external microwave source such as a mobile phone mast, or an internal source, such as a digital cordless phone in an adjacent property.
• The paint has been tested by the Microwave Laboratory of the University of the German Federal Armed Forces in Munich. One layer has a shielding effectiveness of up to 99.99% Multiple layers can even improve on this.
• For use with roller, brush or sprayer. The paint needs between 12 and 24 hours to dry, depending on temperature and humidity.

Earthing

To ensure good earthing connection from a wall painted with the exterior paint, you might want to use the earthing kit in the picture. Step by step instructions for the mounting of the earthing connection set are sent out with a purchase of the earthing kit.

In some countries, external conductive paint, or metal surfaces, must be earthed by law. In the UK, it is not a legal requirement.

You can use the earthing lead for inside and outside purposes. For use outside, it should be adequately protected from the weather by being painted over with the top coat used to cover the screening paint.

IMPORTANT - If you live in the Isle of Man or Guernsey, we will NOT be able to deliver paint to you, even though you can place the order online. We will refund your money and not fulfil your order, so please don't place it. You can still order any of our other items, it's only paint that has proved to be extremely difficult to get to those destinations. Alternatively, as we have no problems delivering anywhere else in the UK, we could organise delivery to a family member or friend (who lives on the mainland) who is coming to visit you so that they can bring it with them.
