3. Medium-grit sanding with 60 grit. This cut crosses the previous cut - perpendicular to it. Before you stop the sander and start to go back, do not forget to lift the drum! Otherwise you will make a hole.
4. After using the big sander, use an edge sander for corners and along the walls. Start with 40 grit and work down to fine sandpaper. Start with 60 or 80 grit if you want to stain or oil your floor. Otherwise it will be very hard to smooth off scratches left by 40-grit or coarser paper.
5. After coarse sanding, vacuum and fill joints. The filler is made from the sanded dust of your floor after the 60-grit sanding. We mix dust and special glue and apply it to the gaps. After 30 min, we repeat the filling process where filler has shrunk into joints. After 1 hour, when filler is dry, we can sand the floor again. We use 80-grit to sand off rest of filler.

6.We use 80-grit paper and then 100-grit, following the grain of the wood.
7. We finish with the edge sander along the sides and corners.
8. We install skirting boards and saddles.
9. We vacuum the floor and finish unsanded spots with the small ex-centric sander.
10. The finishing touch! We use a buffer with 120-grit paper to make the perfect smooth finish before applying varnish.
11. We thoroughly vacuum the floor and finish with a roller to apply varnish or oil. Shake the solution well before applying!
12. The first layer is the so-called baseline and after the varnish is dry, the floor must be polished gently to remove any fine fibres standing in the first layer, using 120-grit paper. Thoroughly vacuum again and then apply second and third layers of varnish or oil.
13. Take good care of your newly-renovated floor by using quality products to maintain the wood and extend its life.
