CD50® is an oil timber preservative for interior and exterior use, designed to penetrate deeply into any species of timber, and protect the timber from within.

CD50® gives resistance against decay, rot, fungus, mould and termites.
It provides water repellency and controls warping, cupping and splitting of the timber, known technically as "dimensional stability".

CD50® is a clear product, and when used on timber alone, the timber will silver with age to produce a natural weathered appearance.

CD50®'s specially formulated Colourtones can be added to the clear product to enhance and maintain the natural timber character and colour. Colourtones are available in a wide range of colours .

CD50® works deep in the timber and is not a surface film forming product. It will not crack, peel or flake.

CD50® was developed in New Zealand and contains the broad spectrum highly effective fungicide Copper 8 Quinolinolate. "Copper 8" is stable to ultra-violet light which is an important consideration in high UV areas such as New Zealand.

CD50® when applied to timber, has little or no mammalian toxicity and is suitable for use on wood that has incidental contact with food. As a liquid, CD50® is very low in toxicity and is rated as a non-hazardous product.

How to use CD50® Liquid Art

The surface must be free of sealants, coatings, or barriers on the surface, which could prevent CD50® penetrating deep into the timber. This includes paints, stains and oils.

The timber must have a moisture content of no more than 17 %.

The surface must be clean and free of mould and stains before application. If necessary, clean first with either SARA-CLEAN or WAY2GO .

CD50® - with or without Colourtone added - is applied to the timber, and a second coat is applied a minimum of four weeks later. Further applications may be required after 2 - 6 years depending on the porosity of the timber, and the exposure to the weather and sunlight.

CD50® is very easy to apply - by spray, brush, speed brush or roller. CD50® can be used on new or old timber, on tanalised timber and plywood.
