Sanding
Example of when a Bona FlexiSand is most suited:
If you want to apply an additional layer of varnish over already applied varnish, you must nap up the
surface somewhat in order for the new layer to adhere. See the product information for Bona Prep for
further varnish layers.
Sanding with a belt/roller sander and edge machine can leave uneven areas in the floor surface
depending on different sanding methods. Sometimes these can be seen with oiling, staining or in darker
parts of the floor. Sanding with Bona FlexiSand evens out these differences and gives an even floor a
perfect surface.
When the first layer of varnish on clean wood has dried, sometimes wood may rise, thus resulting in an
uneven surface. This can be removed using a Bona Scrad or other abrasive screen that provides an even
surface. This also applies if dust, dirt, etc. have ended up in the coating during drying.
Remember the following:
The sanding capacity is lower than for a belt or drum sander, depending upon lower weight.
There is actually no recommended motion pattern, when using Bona FlexiSand, but it is advisable to sand
across the wood pattern.
If additional fine sanding is desired, then Bona Scrad system is a perfect choice.
Remember that too much fine sanding can “polish” the floor so that the varnish or oil has a difficult time
penetrating deeply. The recommendation is not to use finer than 150 grain on wood – with the exception
of the Bona Scrad system.
Bona Scrad is a thin brown pad, approx. 380 grain, which is used together with a small sanding paper in
the form of a triangle. Fix the sand paper to the pad so that the tip points toward the middle. Try to
centralize the Scrad as much as possible in order to avoid vibrations and wobbling.
Handling
Working with Floor Pads
Bona FlexiSand is a perfect machine for treating wood floors with oil. The lower speed is used in order to
work the oil into the wood and the higher speed when polishing. Remember to always follow the oil
manufacturer’s instructions.
If you use Bona FlexiSand for both sanding and oiling remember to clean the machine thoroughly between
the different tasks.
Colors and purpose of Floor Pads:
White - buffing oil, underlay
Tan - coarser buffing, cleaning
Red - cleaning, oil application
Green - coarse cleaning
Brown - extremely fine sanding
Black - fine sanding
