Tuin is a Dutch garden product company well established in Holland and the UK. This Deluxe Workbench is made from the highest quality timber, kiln dried and slow grown from sustainable sources FSC certified. This process results in a tight grain with a resistance to rot and movement. This product has been manufactured using pressure treatment. This process is often referred to as tanalising and is far superior to any process where wood is only dipped or has a base coat applied. Tanalising involves impregnation with Tanalith E (environmentally friendly) wood preservative, under controlled conditions in a vacuum pressure timber impregnation plant. When impregnated into the timber the chemicals become locked into the timber and cannot be removed. Occasionally the treatment leaves a green/blue residue on the surface which can be simply brushed off. This is a feature that occurs but is not considered a blemish. The residue is not harmful. The time taken for the residue to dissipate will vary with weather conditions. The treatment described above provides a long service life and long term protection from fungal, insect attack and rot. The Luxury Workbench and Integrated Zinc Sink Tank by Tuin is a fantastic product that will be perfect for your shed and greenhouse. The Luxury Workbench features a spacious worktop area with a lower level shelf stretching the width of the table. A sink tank is also integrated to make this an ideal product for any greenhouse. Please note the sink is not water tight and designed as an aid in repotting.
