Hard wax oil processing - How to apply and polish: processing

If you own a wooden floor, you should coat it with hard wax oil. This makes the wood resistant and robust, it is conserved and protected. Therefore, it is particularly suitable for particularly stressed floors, such as in a room with children playing. But all other wooden furniture can be upgraded with the oil. The processing, polishing and application can make any home improvement yourself.

The right wood

Not all types of wood or furniture are suitable to be coated with hard wax oil. So it is not so good for dining tables or kitchen worktops. For hot dishes can form a white wreath on a plate treated with hardwax oil. Otherwise, the oil can be used as follows:
  • open-pore wood well suited
  • here 35 to 50 cl are needed for one square meter
  • also end grain, balsa, fired brick or cork suitable
  • strongly absorbent substrates
  • need more oil
Tip: Hard wax oil darkens a little after hardening. In particular, a contrast in the wood is enhanced and in a previously very light wood, a visually appealing grain effect is achieved.

Required tool

Work up the wood panel

Since the processing has to be done in several steps, different tools and accessories are needed. This should already be put together before starting work so that no unnecessary breaks have to be taken. In addition to the well-calculated cans of hard wax oil, the tools and accessories also include:
  • Gloves that should be used during the application
  • a sander for a large area
  • If only a small piece of wooden furniture is oiled, sandpaper is enough
  • Mouthguard, which should be used during the grinding work
  • Vacuum cleaner with brush attachment
  • Mud and bucket for wet cleaning
  • clean brush for dedusting in corners
  • wide brush or small roller for applying the oil
  • Cotton cloth for polishing small areas
  • Plate machine for large-scale polishing
Tip: If you do not own a grinder or a plate machine and do not want to purchase one, you can also rent these devices for a day or more in the hardware store for a small rent.

Prepare wood

Before processing and applying the hard wax oil is the preparation of the treated wood surface. So that the oil is later absorbed well, the wood must first be well cleaned and sanded. For a parquet floor first vacuum, then wipe with a damp cloth and let it dry well. Only then will be started with the grinding. For this purpose, especially for large areas, a grinding machine should be used which works more uniformly than when working with hands and sandpaper. Thereafter, the procedure continues in the preparation as follows:
  • After the coarse sanding again vacuum and wipe
  • let dry
  • finely grind
  • vacuum again and wipe, let it dry
  • stain the floor or wooden furniture before applying the oil

Grind wooden plate by hand

If the floor is not thoroughly cleaned before sanding and also between sanding, dirt particles may leave deep grooves and scratches in the wood during sanding. It is irrelevant whether an old floor should be worked up or a new floor was laid.
Tip: If the wood is pickled after sanding and before applying the hard wax oil, then this will later absorb the oil better.

Further preparation

If the wood has been prepared, then it can go to the processing of hard wax oil. This is usually supplied ready to use and must therefore not be diluted. For work use a clean little brush for the corners and edges, as well as a clean wide brush for the surfaces. Even a small roll can be used for the surfaces. Then proceed as follows:
  • Shake well with oil before use
  • use only in a well-ventilated area
  • Plants, animals and children should not be nearby
  • Humidity in the room does not exceed 85%
  • Room temperature should be between 12° Celsius and 25° Celsius
Tip: Even if there is an aquarium in the room in which the parquet is to be renewed, then this should be taken out of the room before working with the hard wax oil.


If all necessary measures have been taken then the oil can be applied. At work, it is recommended to wear gloves for your own protection. A mouth guard is also helpful, so that no toxic vapors are inhaled. For a parquet floor is started in the furthest corner of the door. For a piece of furniture, start with the corners and edges. The procedure is as follows:
  • in an evenly covering layer, raise the oil
  • always work in the wood direction
  • Always streak with a brush or roller
  • do not make short brushstrokes
  • usually two steps are necessary
  • wait about 8 - 10 hours before applying the second coat
  • it may also be necessary to have a third layer
  • that's because of the wood
  • however, drying between two coats must not exceed 18 hours

Apply hard wax oil - difference

Tip: A sealant can not be applied to parquet treated with hard wax oil. However, in order to increase the protection of the soil, a third, colorless layer can be applied after two coats of dyed hard wax oil.


After every coat of hard wax oil, the machined surface must be polished. For large areas, it makes sense to use a plate machine. The pad should be either white or beige. Small areas and furniture are polished with a clean, soft cotton cloth. When polishing the wood painted with oil, proceed as follows:
  • polish with oil immediately after painting
  • polish well and vigorously
  • is especially important when working with the cloth
  • so the hard wax oil gets into all pores
  • Uniformity is guaranteed
  • gives a better look
  • then let the wood dry
  • ensure sufficient oxygen supply
  • Open windows in the room wide
The final curing, especially with a parquet floor, is guaranteed after about ten days. A floor can be walked on carefully after only two to three days. Also, the processed pieces of furniture should be reassigned and used only after the ten days. In the first days of cleaning should only be done with a broom or vacuum cleaner on a wet wiping should be waived.
Tip: So that the parquet remains attractive after processing, do not move heavy furniture, but always lift. Felt glides can be glued under chairs and table. Do not place any planters directly on the wood, but insulate well.

Cleaning the tools

The tool and tools should be cleaned well immediately after processing. Use a thinner for brushes and rollers. Put this in a container and put the work materials in it. Even during the break between two operations, the brushes and rollers must be stored in the thinner. Otherwise, the oil dries up and becomes hard and the brushes can no longer be used. Further, when cleaning, pay attention to the following:
  • Do not dispose of residues of thinner and oil in the drain
  • put in a closed container
  • Dispose of pads and rags that have been used during polishing
  • bring to the pollutant and deliver

Renovate small areas

Hard wax oil - difference

Hardwax oil can also be used on small areas, for example when stains have formed. These can be caused by incorrect treatment, for example, a burn on a cigarette or a water stain. The procedure is as follows:
  • Sand the stain locally
  • Remove dust with a brush or cloth
  • coat with hard wax oil the place
  • polish with soft cotton cloth
  • let it dry and re-coat
  • polish again
Tip: The local stain should be treated in exactly the same way as the whole cabinet or the entire parquet. So choose the same color here and maybe paint a third layer with a neutral color. For this it is advisable to keep a rest of oil after the first, large treatment.

Storage of leftovers

If residues of hard wax oil remain after processing, they can of course be stored and not disposed of. However, as the oil is flammable, the storage of residues should be done as follows:
  • Close container well
  • Store in a dry, well-ventilated and cool room
  • Boiler room is not a good choice
  • Keep away from any danger of ignition and heat source
  • in the storage room also not smoking
  • Also protect hard wax oil from frost
