Hand Sanding - to sand difficult to reach areas
scrape and sand the floor by hand. Use a scraper to
remove old finishes, always scraping in the direction
of the grain, and then sand by hand using the same
grit abrasive as you finished with when machine
sanding. See Floor Sanding Technique diagrams on
page 4.
FLOOR TYPES
PLANK STRIP FLOORS&
Old floors in good condition - when the floor is in
good condition - no uneven edges, cupping or
crowning of planks and strips - and you want to re-
surface the floor, sanding back to new wood, start
sanding in the direction of the planks or strips - with
the wood grain. Start with a medium grit abrasive.
Complete the first cut with the 8Multi-Speed DrumHT
Floor Sander at speed setting 2 or 3. Then sand up to
the baseboards and door thresholds with the 7HT
Disc Floor Sander, using a medium grit abrasive,
blending the edges in with the main floor area. Sweep
the floor. Using a medium/fine grit abrasive, sand the
main floor area with the 8 Multi-Speed Drum FloorHT
Sander at speed setting 1 or 2 and then complete the
floor with the 7 Disc Floor Sander using a fine gritHT
abrasive. Sweep the floor. Finish sanding the main
floor area with the 8 Multi-Speed Drum FloorHT
Sander using a fine grit abrasive at speed setting 1 or
2. If the floor is in particularly good condition (level
with no deep scratches or blemishes) you may re-
surface the floor using the Orbital Floor Sander,HTF
however, as the sanding action of this machine is less
aggressive than the 8 the job will take more time.HT
Uneven floors - when the floor is uneven sand
diagonally at 45 across the room in both directions
o
using the 8 Multi-Speed Drum Floor Sander with aHT
coarse grit abrasive using speed setting 3 or 4. Only
make one cut on both diagonals, this will achieve a
basic level. Now complete the floor as for a level strip
or plank floor. Use the same grit abrasive as was
used on the 45 cut for the first cut parallel to the
o
planks or strips.
Floors with an existing finish - when re-finishing a
floor remove as little of the existing surface as
possible. If the old finish is worn and the floor is
generally in good condition use the Orbital FloorHTF
Sander with the Hiretech abrasive pad and adhesive
backed abrasives sheets which have been especially
designed for re-finishing floors. These will maintain
the integrity of any stain used to colour the wood and
prepare the surface for a new coat of finish. If the floor
is badly marked and scratched and has to be sanded
back to new wood use the 8 Multi-Speed DrumHT
Floor Sander and 7 Disc Floor Sander. Always tryHT
a medium grit paper first, particularly on a diagonal
cut. If 90% of the old finish is removed and the floor is
generally leveled, you do not need to use a coarse grit
abrasive.
VENEERED LAMINATED THINNER FLOORS,&
Use the -2 Orbital Floor Sander for veneered andHTF
laminated floors or thinner floors that may have been
subjected to repeated sanding. The will removeHTF
old surface finishes and prepare the floor for re-
finishing. Sand the floor using the same method as a
strip, plank, or parquet floor. If the floor has deeper
scratches or marks these should be sanded out by
hand and blended in with the main floor. To check the
wood depth in the floor remove a baseboard or
molding from around the edge of the floor. This
should provide access to the edge of the floor for
inspection.
PARQUET BLOCK FLOORS&
The grain of the wood will run in a number of
directions. Depending on how uneven the floor is
sand the floor diagonally in one direction and then
diagonally in the other direction, like an X. The final
sanding pass should be in the direction of the main
source of natural light in the room. If there is no
source of natural light sand in the direction of the
longest side of the room or, if the room is square, in
the direction the furniture is laid out and how people
normally use and view the room.
This technique will help mask any imperfections in the
floor. Complete the sanding operation as detailed for
plank or strip floors.
BETWEEN COATS OF FINISH VARNISH()
Use the Orbital Floor Sander to sand betweenHTF
coats of floor finish, particularly when using water
based varnishes. These types of finishes tend to swell
and raise the wood grain when first applied to raw
wood. Allow each coat of varnish to dry completely
following the manufactures directions. Use the
Hiretech Abrasive Pad to sand between each coatHTF
of varnish. The fine abrasive pads will remove light
brush/applicator marks and the raised grain while
maintaining the integrity of the coat of varnish
applied.
