Tips for our wood products

Each type of wood exhibits unique properties and characteristics. This can cause wood to expand or shrink under certain conditions, such as variations in humidity. This can affect the dimensional stability of the product, but has no impact on its durability.

Seams, knots and brushes

Annual rings, seams and knots are part of the character of the wood. Knots and knots in the trunk are the result of side branches of the tree. The amount and type of knots depends on the type of wood. Annual rings say something about the age of the tree.

Tip! Loose knots or brushes can always be reattached with wood glue

Expansion, shrinkage and cracking

Moisture or dryness causes volume changes, which can cause wood to expand or shrink, which can cause cracks. The higher the durability class, the smaller the dryness cracks. Incidentally, wood working only occurs under humid conditions or uneven drying of wood.

Tip! Make sure that wood can "breathe" by removing it from the packaging in good time before use and do not leave it in direct sunlight.

Color difference / graying

When making it durable (impregnating), various colour pigments are added to the wood. Depending on the wood and the storage, these pigments will come to the surface. These colour differences will slowly disappear under the influence of sunlight. Over time, even impregnated wood will become lighter and grey under the influence of ultraviolet in sunlight.

Mold (white spots)

Superficial mold stains in wood can occur when wet parts are stacked closely together for some time, which can happen during production and transport.

Tip! Mold is easy to remove with a cleaning agent (such as vinegar or bleach) or a special mold removing agent. Incidentally, it will disappear over time due to the weather.

White and green spots (salt spots)

With impregnated wood it may appear as if salt formation occurs on the surface of the wood. This discolouration of white and greenish spots occurs in combination with impregnating agent and resin. These spots disappear by themselves.

Tip! Easily removed with a damp cloth.

Resin

To protect against viruses and infections, a tree produces resin. This is a natural phenomenon and the amount of resin can vary considerably per tree. After the resin has hardened, it can be easily removed. Green specks are usually present on pine wood due to the mixing of resin with impregnation agent.

Tip! Green specks are easy to remove with a brush. It is possible to carefully scrape away any resin drops or remove them with turpentine.

Bleeding

Tropical hardwood in particular can leak fluids, which are sometimes white, red or brown in colour. These substances are harmless but can stain underlying work or mix with the applied paint layer. The so-called "bleeding" stops by itself after a while.

Tip! Only work with well-dried wood. Preferably apply two base coats on turpentine basis with a drying time of 24 hours. Still spots? They disappear with time by rain or by using bleach.

Heartwood and sapwood

A tree contains sapwood and heartwood. The heartwood provides strength, while sapwood transports the nutrients. The sapwood has a lighter colour in some types of wood, such as pine and Douglas fir. Construction - wood consists partly of sapwood, small parts such as slats and planks can contain more sapwood. Sapwood is naturally less durable.

Mini drill holes (pinholes)

During the growth of a tree, small insects occasionally enter the tree in search of nutritious sap streams. In doing so, they bore small (sub-millimetre) holes in the wood, which only become visible when the wood is sawn. Insects do not survive in dead wood and therefore do not pose a threat to the durability of the wood. Pinholes are most common in hardwood, but can occur in varying quantities in all types of wood.

warping

Deformations due to weather influences, as long as these do not affect the workability/assembly. This means that curvature perpendicular to the door plane and deflection of the door leaf out of the plane are permissible, as long as this does not hinder the workability/assembly. The permissible deviation of the door leaf from the plane is 20 mm. We recommend treating untreated wood with a covering layer as soon as possible, so that the wood is protected against weather influences.
