Sand parquet flooring, seal it and bring it back to life
Important when sanding wooden floors
Multi-layer parquet has a wooden running layer of 2.5 mm to 6 mm. When grinding, approx. 0.5 mm is removed, so you can carry out several grinding passes. As a rule, for parquet floors that are not so damaged, three sanding passes with different grain sizes are sufficient. You start with a coarse (24, 40 or 60 grit) and finish with a fine sanding (100 to 120 grit). For the sanding process it is good to use a parquet sanding machine. These can be rented from specialist timber shops or hardware stores. You will usually receive a small instruction manual for this. It is best to read this through quickly on site in order to resolve any ambiguities immediately. After sanding, the floor should be sealed with wax, oil or varnish.
Use the grinder as directed
Tips for operating the grinding machine
In order to do a good job and avoid expensive machine damage, there are a few things you should consider when operating the grinding machine. To prevent grooves from forming on the floor that can no longer be repaired, you should only lower the roller on the floor when the machine has reached full speed. Run the grinding machine smoothly and evenly and at the end of a grinding cycle lift it carefully. Avoid changes in direction and do not stop while the machine is running.
Extra tip: To sand the edges and corners in the room, you will need a special edge and corner sanding machine.
To avoid deep marks in the roller, you should pull out or countersink all nails before sanding. A lot of dust is created when sanding parquet floors. So think of protective clothing and wear a breathing mask to protect against fine dust.
Hide the longstanding traces
Sand parquet flooring step by step
Prepare the following:
- Painter’s foil
- duct tape
- Parquet spatula
- Varnish, oil or wax
- Grinding machine
- vacuum cleaner
The instructions in 5 steps
Step 1: First of all, the room should be cleared. Heavy furniture and objects that you cannot get out of the room, cover with foil and tape them off. Put down the curtains and drapes. Also use the hammer and chisel to remove the baseboards and nails. Before you start sanding, you should thoroughly clean the floor.
Step 2: The first, coarse sanding process is used to remove the old paintwork and dirt. Use 24 or 36 grit sandpaper for this purpose. This sanding should be done diagonally to the grain of the wood. Dust off the parquet floor before you go any further.
Step 3: Use 60 grit sandpaper for the second sanding. Here you should pay particular attention to the laying direction of the parquet so that you can remove sanding marks from the coarse sanding and other unevenness. Corners and edges are sanded off in circular movements without pressure. You should then vacuum the dust again. Use parquet filler mixed with sanding dust to repair cracks.
Pay attention to the grinding direction
Tip: Herringbone parquet should be sanded in diagonal lengths with the grain. Mosaic parquet diagonally to the course of the fibers and strip parquet at an angle of 7 to 15 degrees along the grain.
Step 4: The final fine-tuning is done with a 100 to 120 grit. This is carried out parallel or across the incidence of light. This gives the floor a completely smooth surface again. Then the floor is dusted.
Step 5: Finally, the parquet floor must be sealed. You have the choice between oil, wax and varnish. The varnish seal is a little more complex, as a primer comes first, which should be sanded off and cleaned after drying with emery paper with a grain size of 120. Only then is the sealing wax applied. With the oils you have the choice between hardening and non-hardening. At least two steps are required and if you use non-hardening oil, you will need an additional protective layer of wax. Inquire about the processing in the special needle.
The effort involved in sanding and sealing parquet floors depends on how much the floor is used. The task is a bit exhausting, but the beautiful and shiny result is definitely worth it!
