PREVENTATIVE AND CURATIVE TREATMENT WITH NAHOS code 1035

Use	Interior / Exterior (if covered with a coloured finish)
Phase	Water based
Composition	Water, Aluminium Oxide, Calcium Oxide, fruit acids, Potassium Palmitate, Silicate, Silicate acid, Magnesium Oxide, Sodium Carbonate, Sodium Chloride, translucent vegetable colours, vegetable fats, vegetable oils.
Properties	Nahos is a concentrated product, free from solvents and artificial pesticides, which can be diluted with water for the preventative and curative treatment of wood. Made with minerals and vegetables from renewable sources, it works against wood pests without emitting any toxic or noxious fumes. The product is colourless, can be used in areas of food preparation or on structures where livestock is kept such as beehives and can be applied in rooms with no ventilation. The organic compounds are biodegradable. NAHOS strengthens wood which has been attacked by insects such as woodworm and is fire retardant. It is micro-porous and allows the wood to continue to regulate moisture levels. It acts against bluing of wood (coloration may appear on application which will disappear when dried.) The natural structure of the wood is maintained and the surface takes on a light satin sheen. The primary activity of NAHOS is the modification of the cell structure of the wood. This happens through a procedure of mineral silification which renders the wood no longer recognisable or attractive to insects. The wood is strengthened and becomes less flammable. The cells of fungi and moulds are destroyed during the procedure of mineralisation. Insects are trapped in the existing holes and runs within the wood while the product prevents further attack by the process of silification.
Areas of application	NAHOS is used for the preventative treatment of wood against insects and fungi. In curative treatments it can be used against death-watch beetle and other insects of similar size as well as wood affected by bluing. It strengthens infested, crumbling wood, in the process rendering the wood less flammable. NAHOS is particularly suitable for the cleaning, restoration and care of old buildings and antique wood. It is also suitable for rooms needing to conform to regulations for food preparation, rooms occupied by the sick, for those suffering from allergies, for childrens rooms or for structures where livestock is kept (beehives, stables etc).
Preparation	The wood to be treated must be clean, dry and free from dust and grease. Wash down with water or soap and water (the soap must be of neutral ph) and left to dry thoroughly. Old paint and/or varnish must be removed.
Directions for use	Stir the concentrate thoroughly, add 9 parts of water to 1 part NAHOS and stir thoroughly again. Apply the mixture with a brush, spray gun or by dipping. Wait until the first coat has dried thoroughly before applying the next coat. Apply about 200ml per m² and apply two to three coats. While you are working, stir the mixture regularly. In case of insect infestation, inject the product directly into the insect runs using a syringe or a pressure gun. If the infestation is severe, then use a less diluted solution (1 part NAHOS to 5 parts water). Exterior treated wood must be lightly rubbed down after the wood is dry and painted with a coloured finishing product such as shellac or a stain. Caution! Do a preliminary patch test before using the product. In case of spillage on metal, wash immediately with water. If there are fungi or moulds found on the product when the container is first opened they are not a sign of defect but rather an indication of the biological purity of the product showing that there are no preservatives used. The mould can be lifted off the surface and the product used as normal.
Coverage	One litre of NAHOS diluted with nine litres of water will treat about 50m² (one coat). The amount of product used will vary depending on the type, absorbency and thickness of wood. Wood which is much damaged, rough sawn or wood with heavy insect runs will need more product than average.
Drying time	Wood can be re-coated after 24 hours (at 200 °C and 60% air moisture)
Cleaning of materials	With soap and water.
Storage	Store in cool, dry conditions. Close any used containers tightly and protect from frost.
Availability	Available in 250 ml and 1 litre
Safety precautions	Natural products should be kept out of reach of children. Recycling Dispose of empty containers and any remaining liquid at a recycling centre. Any dry residue can be thrown away with domestic rubbish. Recycling code for liquids: 060199
