Parquet lacquer effectively equips the parquet for daily influences. The applied coating coat seals the parquet surface and provides the necessary protection. What is important when painting parquet, what types and manufacturers of parquet lacquer there are and what to consider when sealing the parquet is in the following guide.
What is painted parquet?
In order for parquet to receive the necessary protection against external influences, a corresponding surface finish is required.
It makes the wooden floor more resistant and robust,protects it from dirt, moisture or wear and also adds the finishing touches to the look of the parquet.
Parquet can be either finished with oil, wax or varnish – which method is best depends on the degree of stress and the personal demands on the parquet.
Pros and cons of lacquered parquet
In contrast to the finishing with oil or wax, which impregnates the parquet surface only, the wood is sealed with parquet lacquer completely.
The applied lacquer forms an additional protective layer on the parquet floor, which effectively protects the floor from dirt, abrasion and moisture.
Accordingly, painted parquet is considered to be more robust than oiled parquet.
The painted surface is generally easier to clean and requires less post-treatment.
However, damage to the parquet varnish due to the full-surface sealing is not so easy to repair.
In contrast to oiled parquet, it is more often necessary to grind and repaintthe parquet.
In addition, some of the naturalness of the floor is lost due to the parquet lacquer: the painted protective layer closes the pores of the wood and – unlike with oiled parquet – can no longer “breathe”.
In terms of the indoor climate, an oiled floor sometimes proves to be more advantageous, but the pleasant living atmosphere is maintained even with painted parquet.
What types of parquet lacquer are there?
Whereas parquet lacquer used to have a reputation for being highly solvent and therefore harmful to health and the environment, this is no longerthe case with parquet sealing.
Most modern parquet lacquers are water-based with a very low solvent content of up to 15%.
The term water varnish refers to the high water content of about 55 to 70%in which the components of the paint are dissolved.
However,water-based parquet varnish does not mean that the paint is water soluble or that the parquet seal is more sensitive to water.
Water varnishes are also particularly recommended because they are easy to process and apply and also have a very high resistance to abrasion and chemicals.
According to the composition and protection intensity, the water-based parquet lacquers as follows:
1-component parquet lacquer
Conventional 1-component parquet lacquer is mostly made of plastic (acrylate) or synthetic resin dispersion. The 1K parquet seal provides solid basic protection for the floor. However, acrylates can become brittle and in particular in places with strong light irradiation or permanent water exposure peel off or tear after only a few years.
2-component parquet lacquer
Parquet varnish of the 2-component sealing is additionally enriched with a so-called hardness component, which reacts chemically with the paint before processing. By curing the two components, the parquet sealing becomes much more resistant and robust against abrasion or scratches. 2K-lack not only offers higher-quality protection, but also hardens faster, which makes the parquet accessible earlier.
3-component parquet lacquer
In addition to parquet lacquer and hardening components, a 3-component parquet seal also contains additional UV protection,which protects the parquet floor – similar to the principle of sunscreen – from UVA radiation. This prevents the parquet from being over-yellowed or darkened, which is why 3K parquet lacquer is particularly recommended for light floors.
Alternative parquet seals
Also as 1K and 2K parquet lacquers, lacquers are polyurethane base. These are also referred to as pur or DD coatings However, seals are highly solvent-containing and lose less harmful water-based parquet lacquers. The previously widely used oil-resin parquet sealing: these too oil-based method was characterized by the high proportion of solvents have now been completely replaced by water paints.
How does parquet sealing work?
No matter which parquet lacquer is used – the sealing works for all by evaporation of the ingredients in different order.
In the case of water varnishes, first the water and then the binder evaporates, creating the paint layer. In polyurethane parquet coatings, the protective layer is formed by evaporation of the solvents and chemical reaction of the residual synthetic resins, which is sometimes associated with a biting smell that evaporates only slowly.
Shiny or matte?
Compared to oil, varnish offers a slightly different design leeway in terms of the appearance of the parquet.
Because parquet lacquer is hardly coloured, only occasionally manufacturers offer parquet lacquer in white.
However, it is possible to vary how shiny the parquet should be: Most parquet lacquers are available in matt, semi-gloss or high gloss. If the floor should nevertheless be changed in color, e.g. to refresh old, yellowed parquet,the parquet must first be dyedwith pickle or oil. Only then can it be sealed with parquet varnish.
Best parquet lacquer: This is what matters
The differences between the individual products lie in their exact composition, the intensity of protection and, of course, the price. Accordingly, the field of application also plays a role when it comes to buying the appropriate parquet lacquer.
The cheapest version is 1K parquet lacquers. They are easy to apply and adequately protect under-stressed parquet from damage. However, they are limited in their lifespan and therefore not particularly suitable for rooms with high stress, water exposure or solar radiation.
Due to the faster curing and higher resistance to scratches, 2K parquet lacquers are optimally suitedfor average stressed parquet, such as in living rooms.
The higher costs are offset by the longer service life and better protection.
For rooms with high sunlight and heavy loads as well as for stairs, high-quality stair and parquet lacquer on a 3-component basis should be used. Although this is relatively expensive, it not only protects the parquet from yellowing or darkening, but also withstands running loads, e.g. by climbing stairs.

How much parquet varnish is required for sealing depends on the respective parquet or the type of wood.
More varnish must be applied for parquet made of raw wood than on a floor with a primer.
Even hard wood types require less parquet lacquer than soft wood, as it sucks more strongly.
In principle, a guideline value of approx. 1.2 litres of parquet lacquer applies for 10 m2 of parquet flooring per coat of paint. In order to ensure optimum protection, however, the parquet lacquer should be applied not only once, but ideally three times.
It should be noted that the parquet lacquer represents only a small part of the total cost of the parquet sealing.
The majority of the price of the parquet sealing is – if it is carried out by a skilled person – the working time,which is due to the necessary grinding of the parquet.
Saving on parquet lacquer therefore makes relatively little sense – especially because products with lower quality increase the risk that the protective layer will wear out or wear out faster and that a new parquet seal is necessary earlier.
Parquet painting: step by step
In the course of a renovation, the full splendour of the wooden floor is brought back to the fore by a new layer of parquet lacquer.
Painting parquet is quite demanding, but can be carried outwith a little practice and skill by do-it-yourselfers.
For an optimal result of the parquet sealing, the following instructions should be followed.
Preparation: Grinding and cleaning the parquet
Before the parquet can be repainted, it must be completely sanded.
When grinding the parquet, care must be taken to ensure a uniform and careful procedure – the surface should be sanded down to the raw wood.
Afterwards, the fine dust must be thoroughly removed from all surfaces – preferably with a vacuum cleaner or brooms.
The parquet must be completely free of dust particles.
However, the grinding dust can be used to repair scratches or joints in the parquet:simply mix the dust with joint putty to a pulpy mass, fill up damage, let it dry and then process with sanding machine or sanding paper until no more joint putty can be seen.
2. Apply the primer
A parquet primer must first be applied to the sanded raw wood.
For this purpose, the parquet lacquer is carefully stirred and applied uniformly and systematically with a roll on the parquet.
When applying the parquet lacquer, direct sunlight should generally be avoided and the room temperature should be between 18 and 25 degrees.
In order not to hinder the working process, it is best to start in the rear part of the room opposite the exit and pre-work in uniform sections of approx. 2 m to the door.
In order to create a smooth and even coating layer, the primer is distributed once against the laying direction on the parquet and the same section without additional absorption of parquet varnish is coated again in the direction of the boards (so-called “finishing”) .
The individual sections should overlap slightly. Beware of starting tracks when attaching and dissposing the roll!
If the entire floor surface is painted, the primer must first dry for about 2 to 3 hours. Now you can start applying the paint layers.
3. Apply parquet varnish in several layers
The procedure is the same as the one used in the primer. When applying the paint, it should be done quickly so that the paint cannot dry too quickly.
With average stress on the parquet, two layers of varnish are sufficient, in more stressed areas three layers of parquet lacquer should be applied in order to additionally increase the protection. The parquet should also be sanded before any further coating if the drying is more than 24 hours ago. On this point, however, the manufacturer’s instructions must be observed and binding for each seal.
When can the furniture be repositioned after painting the parquet?
After a drying phase of the parquet lacquer of about 8 hours, the floor is walkable again,furniture can be set up after 24 hours. The parquet lacquer is completely cured after about a week – with solid furniture or carpets should therefore be waited until then.
