Grind the plank floor with craftsmanship

Floorboards enjoy a strong popularity. Even old plank floors in old and existing buildings are often deliberately exposed. Then the renovation of the plank flooring begins. The subsequent quality of the plank floor depends significantly on the sanding of the wooden planks.

The plank floor is again on the rise

Floorboards are in the trend as long as not. For many decades floorboards were a must and were literally vilified in the last decades of the 20th century. But with the sustainable and close to nature building and renovation, many people have rediscovered the true value of a plank floor. In old buildings, many years of covered plank floors are partially uncovered and need to be renovated.

Sand a floorboard expertly

But also common wooden floorboards need refreshments. Just as a new wooden floor needs to be maintained for the first time. In all cases, an important and decisive step is the sanding of the board floor. With the quality of the sanding, the inner and visual values ​​of plank flooring also stand and fall. Therefore, we offer here a detailed description of how you can professionally sand your plank floor step by step.

Step-by-step description of sanding a board floor

  • nails
  • wood screws
  • Body oil
  • substitute wax or oil for polishing
  • Cordless Screwdriver
  • Roller or belt sander
  • Random Orbit Sander
  • polisher
  • Alternative angle grinder or disc grinder
  • hammer
  • punch
  • Sandpaper in different grain sizes

1. Preparation

First you have to sink protruding nails and wood screws into the planks. If necessary, some screws or nails have to be replaced.

2. Sanding off the board floor

Now sand off the plank floor in a first step. For new wooden floorboards you use a 40 grit, for varnished wooden floorboards 24 grit and for lacquered wooden floorboards 16 grit of the sanding paper. With the roller grinder you first grind diagonally to the plank course. It may be necessary to use several sanding cycles: old paint layers must be completely removed and overlapping boards sanded flat.

3. Second operation when sanding the wooden floorboards

Now use a sixty or eighty sanding paper on the new board floor, or grained sandpaper on the old board floor of the 40s or 60s. In addition, you no longer grind diagonally, but along the long side of the wooden floorboards.

4. Third and fourth operation when sanding the board floor

Now use again a factor of 20 or 40 finer grained sandpaper. With the old plank floor, you'll probably need to take one more step.

5. Finish - the last sanding or polishing from the plank floor

Now you can either incorporate the wax or oil polish with the polisher into the plank floor or use the angle grinder and a 150 grit sandpaper to finish the surface. Alternatively, and also much easier to handle, you can also use a disc sander.

6. Sand down corners and edges

The corners and edges of the plank floor are dealt with in the respective step with the belt sander, except that you use the eccentric sander here.

Tips & Tricks

After sanding, you can leave the surface of the plank floor untreated, if you have used the polishing and maintenance wax or oil. However, this protective film is not very well adherent, further processing such as sealing, oils, stains, alkalis, etc. is therefore advised.

Grinders can be hired quickly at numerous rental stations, which many companies and DIY stores offer even in smaller cities.
