New hardwood floors

Color and structural differences in the appearance of wooden floors can occur on new board and parquet floors, depending on the type of wood, floor type and appearance of the wood. The differences vary depending on the individual flooring product and make.


When ordering / purchasing factory-made floors with surface treatment, a realistic assessment of the appearance of the floor should be made on a test floor, e.g. at least 2 m2, made up of randomly selected products from the selected sorting.

For larger tasks, eg. parquet floors, which are sanded and surface treated after laying, should be evaluated on a test floor, eg. at least 5 m2, which is agreed upon for the outcome of the upcoming delivery, see also TRÆ 63 and 64 from Wood information.

Wood species

Many tree species have great natural color variations, among other things. dependent on variations in the tree structure. The differences are not always visible when the products are freshly processed. The color and structural differences often occur first in connection with surface treatment. The differences can also become apparent after some time due to normal sun and light effects.

floor types

Normally, slatted floors will appear with a more uniform surface than solid floors, as the upper veneer (wear layer) will most often be colored in accordance with the supplier's specifications.

Solid hardwood floors are usually supplied in one class, while solid parquet floors in European hardwood species are often delivered sorted according to the supplier's specifications, see also sorting quality.

color Differences

Lacquered floors, especially white and color pigmented, which have been surface treated from the factory, can have smaller color and gloss differences from production to production. The same batch number should therefore be used. in the same room and possibly adjacent rooms where surfaces can be compared. In general, attention should be paid to possible shade and gloss differences when mounting.

More significant color differences rarely occur and are mostly due to mis-production.

sorting Quality

If solid wood is used as it 'falls from the saw', the flooring product will vary in appearance depending on the wood quality used and from which geographical area the tree originates. This is especially true for softwood floors, for example. pine, which is usually supplied in one sort, which may vary depending on the supplier. Often there is the possibility of choice between untreated and factory-applied surface treatment.

Most flooring manufacturers sort out light hardwood floors in one or more classes according to appearance, so the floors appear with a greater color and structural uniformity. This applies, for example, to beech, oak and ash. The sorted products will color-coded in classes from the color uniformly uniform without contrasts to completely flamed with large contrasts between the darkest and the brightest parts.

A reasonably similar surface can be obtained from board to board by selecting a sorted floor for classes referred to as e.g. select, prime el Large variations can be expected even within the individual rod / plank when choosing unsorted or rustic floors sorted by names such as. rustic, country, accent el

Tropical wood floors are usually delivered in one sort with the color variations that usually occur in the wood species.

Color changes after commissioning

Some tree species, especially some tropical tree species, change color by aeration from the air - most often from a reddish tone to dark brown.

For all other coniferous and hardwood floors, it is the influence of light and, in particular, the effect of sunlight that changes the color tone of the wood, and partly in the surface treatment.

For example, pine will normally have a deeper reddish tone, and red-brown portions (flames) may occur. Gran will remain more light than guy, and will have a deeper reddish tone over time. For example, ash will become more golden, and color differences between dark and light areas on sticks or boards will be smoothed over time. Similarly for other Nordic hardwood species.

Lacquer on lacquered floors only changes color to a negligible degree, but the lacquer does not prevent color changes of the wood material over time.

For oiled floors, they will change over time due to light effect and oiling, as discussed above. They can also become significantly darker over time due to oil treatment, especially if the floor is not completely clean before treatment. Similarly, lack of maintenance with oil in combination with floor washing will bleach the floors, especially European hardwood floors.

Large color differences will occur where floors are covered by carpets and the like, which protect against light. Here the floors will appear significantly brighter and often close to the appearance of the laying than in the uncovered areas.

Repair of newer wood floors

When replacing boards, parquet rods or plywood rods in newer floors, it will be possible to carry out the repair, so that color and structural differences differ to a lesser extent from the naturally occurring differences on the existing floor. The most important assumptions will be:

- That the existing floor is less than 1-2 years old, without visible wear or damage to the surface and without significant aging after sun exposure.

- That the repair can be done with original boards, parquet rods or lampposts from the original supplier, and that the repair parts have the same surface treatment as the floor. If the repaired floor is to be surface treated after remediation, gloss and lacquer structure differences can occur in the surface due to differences in the application method.

- That when using new wood color differences occur during the repair, which, however, experience will smooth out if the floor is with natural light and sun influence.

White glazed and colored surfaces

Repairing white-glazed surfaces on both younger and older floors can be very difficult, as the color pigments on surface treatment tend to accumulate in joints, scratches and cracks in a worn wood surface.

Often the best result will be a complete abrasion of the surface for clean wood and a new treatment of the floor.

Maintenance of oiled or lacquered white glazed surfaces should be done before visible signs of wear in the floor surface, see more in TRÆ 63 Wood flooring - Selection and maintenance.

The surface of stained and similarly colored wood floors can be difficult to repair satisfactorily, even when sanding into clean wood and reprocessing. The use of colored oils for reprocessing can produce the same effect as pickling and is easier to work with. For very worn floors, replacing the floor will often be the best solution.

Repair of worn or older wooden floors

Where the wooden floor surface is affected by wear and sunlight over a long period of time, a repair of the floor surface by e.g. Replacement of boards, parquet rods or plywood with new repair parts could not normally be carried out, so that the floor surface appears uniform.

Repair of old board floors by pine can in certain cases be performed satisfactorily if it is possible to purchase used boards of similar type.

  • If, in the case of a retrofitting of an older floor, it is desired that the floor surface subsequently appears to have a completely uniform appearance, whole floors should be abraded to clean wood and surface treated after the necessary repair has been completed. However, larger marks, cracks and holes will rarely disappear.
