Whether pine or eucalyptus, premium or standard, opaque or natural - requirements in the surface treatment of garden furniture are diverse. Teknos also has the right solutions for this segment in its product range.
Terraces and garden are a popular place to relax and rest. It’s no wonder that the demand for outdoor furniture is continuing worldwide. Material combinations and composite materials have gained considerable momentum, but wood still plays an important role in this segment. In Northern Europe, domestic softwoods are particularly in demand for outdoor furniture. Hardwoods dominate the rest of Europe and in Asia, primarily varieties such as eucalyptus or acacia.
The garden furniture market is fiercely competitive. It is key for manufacturers to produce market-driven quality in efficient processes. Requirements on coatings are demanding here. Today, look and feel play a considerably bigger role in garden furniture than ever. That’s why surfaces on a wider range of wood qualities also need to be perfect, smooth and as durable as possible. In addition to this, garden furniture has a high proportion of horizontal surfaces, which are even more exposed to weathering than the wooden surfaces of protected construction elements, for instance. Standing water and UV exposure require a reliable coating to achieve the durability needed.
Fast, cost-effective processes are required in the processing. That means for the coating: Short runs with the fastest drying possible and minimum sanding needs. The processing properties of the coating solution have considerable influence on the competitiveness of the end product.
Teknos offers industrial manufacturers in this segment a wide product range of suitable coating solutions, covering all of the typical requirements. Market conform, practice-tested impregnations, multi-purpose and special primers, fillers, opaque and translucent topcoats for a variety of substrates, surface requirements and processes are available. The most important system recommendations for typical requirements are listed below.
Garden furniture made of pine or other softwoods are primarily produced for the Central and Northern European market. Typical coating is opaque white. This results in two important requirements: Non-durable softwood must be protected from blue stain and wood-destroying fungi, and discolouration from knots and water-soluble wood substances should be prevented. Teknos recommends for this application a four-coat system with impregnation, special primer, primer and topcoat:
In many parts of the world hardwoods are predominantly processed for opaque painted garden furniture. In addition to premium woods, light colored, cost-effective wood species such as eucalyptus and acacia are used for the price-sensitive mass market. These woods are not so durable, but from an cost-efficient perspective often do without impregnation. However, a reliable protection against the bleeding of tannins is essential. When coating with water-based coatings, the water-soluble substances are released, bleed into the topcoat and can lead to brownish or yellowish discolouration on white opaque surfaces. So, it’s recommended to use a coating system with a suitable special primer:
Wooden garden furniture is largely exposed to UV radiation and needs a reliable UV protection with low-pigmented coating. Without this protection the UV rays break down the lignin into water-soluble components, which then can be washed out and ultimately break up the outer fibre layers and cause the coating to flake. Another requirement is the appearance: Translucent coatings are intended to accentuate the natural grain in the wood. The darker the colour, the more important it is that the translucent coating does not have a milky effect and produce a shadow appearence.
When using softwoods a prior impregnation against blue stain and wood-destroying fungi is also required. This is also recommended for non-durable hardwoods, for example eucalyptus. There is a requirement, depending on the region, to protect the wood from specific insects. An appropriate coating system is below:
In the case of garden furniture made of durable hardwood there is a requirement to accentuate the natural appearance of the wood as much as possible and leave an untreated effect on the surfaces. The low film formation required for this, however, is not possible with a three-coat system. In these cases we need a coating with low dry substance content, which maintains the original colour of the wood. Treatment is not permanent, but has to be regularly refreshed by the end customer. For this special requirement Teknos recommends:
The coatings specified are recommendations for typical requirements. In individual cases the specific requirements in terms of substrate, surface finish to be achieved, process properties and possible special requirements of the respective market shall be taken into consideration. In the choice of the optimum coating solution manufacturers can rely on the support of the Teknos Application specialists. The Teknos experts have many years of experience with a wide range of requirements in many international markets.
