The micro, hollow glass beads act like miniature 'Thermos Flasks', blocking thermal energy by reflecting it away from the wall and protecting the walls from damp, which causes moisture and therefore mould growth. All of these properties combined enables Thermaldry to increase the wall temperature, thus reducing the 'dew point' or the temperature at which condensation occurs. Ideal for use in: Bathrooms Utility Rooms Kitchens Lintels over windows and doors which produce cold spots Cold walls and ceilings Industrial Applications Coating is waterproof when dry and walls are warm to the touch Prevents formation of black mould and other harmful fungi Reduces the risk of condensation Reduces thermal conductivity by 4 times, saving energy and fuel costs in your home Increases the life of your chosen paint or wall paper finish Can be applied over existing paint or wall paper, plaster, brick, concrete, metal and plastic Can be over painted or wall papered over with any finish, without reducing its effectiveness Suitable for any interior wall - Particularly exterior facing walls, bathrooms and kitchens Eco-friendly, antibacterial properties Size: 2.5 litres
