PRODUCT DESCRIPTION
RAW Industrial Parquet is made
of solid wood narrow strips in
different wood species that are
fully glued down to the substrate.
After installation, the parquet
must be sanded, fully coated with
filler and surface finished on site.
This traditional industrial parquet
provides a somewhat more rustic
and genuine feel because the
surface can never be absolutely
perfect. On the contrary, there are
minor planer bites, knotholes, filler
and flaws left when the floor is
finished.
Almedals RAW Industrial Parquet
is supplied in slightly larger
dimensions than normal: 14 x1
4 x approx. 250 mm. The larger
dimension allows a significantly
better installation surface against
the parquet glue. The risk of
strip separation is consequently
very low compared with ordinary
industrial parquet of small
dimensions.
DESCRIPTION
The parquet is fully glued down to
the substrate, which provides very
good room acoustics.

sections taped together.

using a floor sanding machine and 16 grain
sandpaper. Cover thereafter with birch
plywood, min 4 mm, which is fully glued
down flush against
the substrate using parquet adhesive. The
plywood must be fully glued down to the
plank floor and either screwed down or
stapled. RAW is fully glued down to the
plywood in any direction.
PARTICLE BOARD, FLOATING
Poured concrete slab with max RH of 90%
is covered with age-proof plastic laid with a
minimum overlap of 20 cm. 22 mm flooring
particle board is laid floating over the
substrate. RAW is fully glued down to the
particle board in any direction.
See Hus AMA KEJ 234
MDF PANELS

comparable, there is risk that the adhesive
will separate from the substrate in spite of
the sanding.
NOTE In these cases, you should contact
the adhesive manufacturer directly.
There are no technical barriers to
combining RAW with subfloor heating.
The adhesive supplier should always
be consulted about gluing down wood
flooring to the substrate.

INSTALLATION INSTRUCTIONS
You must read Almedals installation
instructions before you begin the installation. If you are unsure about anything, you
must contact Almedals before the work is
begun.
The floor is not limited as to the size of
contiguous surfaces that may be installed.
However, the floor should not be glued
over any movement joints in the underlying
concrete floor.
Before the floor installation is begun, you
must check that the substrate is level and
meets standard requirements set out in
AMA Hus 11.
NOTE We recommend black parquet glue
for the installation of smoked oak.
Check that the temperature in the room is
about 20 degrees Celsius at 30-60% relative humidity.
Check that the packages are labelled with
the right floor before they are opened.
HANDLING
PACKAGES
RAW is delivered in sealed plastic packaging.
STORAGE
Store the packages unopened until they
are installed. The parquet must have had
enough time to adjust to the room temperature of approx. 18-22 degrees C before it
is installed.
INSTALLATION
Installation direction: We recommend that
the strips are laid crosswise to the source
of natural light.
Lay the parquet sections straight down
on the glue - avoid pulling them sideways,
because this can cause side gluing.
Install the next row offset cm) to create a
brickwork pattern. The parquet should not
be installed side by side with no offset.
The strips should not be laid so that they
lie flush together.
Snap out a start line approx. 50-100 cm
from the wall. Thereafter, install a straight
edge or starting board along the start line.
Calculate the number of full parquet widths
towards the wall and add a 1 cm expansion
gap.
When you have installed the entire start
field, it is a good idea to lay a straight edge
or straight board against the last row. Use
a hammer and tap lightly on the board to
push the rows together.
Snap out another line 2 section widths
away parallel to the start line. Remember
that the line should be about 1cm inside
the edge of the parquet row. If for example
2 parquet rows have a total width of 500
mm, the next line should be placed at 490
mm. This prevents the glue from being
pressed out alongside the last row and
drying.
Continue gluing in fields of approx. 50 cm
wide. Snap parallel lines with a chalk line
to check the installation. Install the parquet
sections parallel to the lines. Do not tap
them together sideways - you must accept
some gap formation between the rows.
You may saw the parquet elements with
either a circular saw with a guide bar or a
bandsaw.
No apply the parquet glue in the start field
of approx. 50 cm.
RAW can be rolled before the glue has
dried, but this is not required. It is however
important that the floor is pressed down
into the glue and not only laid down.
Open at least 2-3 packages and distribute the parquet before installation. This is
done to ensure a correct result where the
appearance of the parquet varies among
the rows.

SANDING & SURFACE FINISHING
INSTRUCTIONS FOR SANDING
& SURFACE FINISHING
Almedals RAW INDUSTRIAL PARQUET
must be sanded and surface finished on
site. The floor must be fully coated with
filler in connection with sanding.
The floor can be sanded either with a
traditional floor sander or with an orbital
pad sander. The difference is that the
orbital pad sander provides a more even
result with no sanding lines and clearly
accentuates the annual rings. Nor do any
differences arise along the walls due to the
different types of sanders.
SANDING
SURFACE FINISHING
Choose one of the following alternatives to
describe the sanding method.
Almedals recommends hard wax oil,
floor oil, or floor varnish. Almedals has no
restrictions with regard to different manufacturers.
Please refer to each manufacturer’s
instructions.
Alt. 1
The floor is sanded with a Bona Power
Drive (rotary polisher) and 50/100 sandpaper.
Alt. 2
The floor is sanded with a floor sander (belt
drum) and 120 grain sandpaper. Preferably
start with 24 grain or 36 grain, followed by
50/80. 80 grain for edge sanding.
Thereafter, sand the floor with an orbital
pad sander using a 100 grain sanding
mesh.

CARE INSTRUCTIONS
RAW Industrial Parquet can be surface
finished with floor oil, hard wax oil, or floor
varnish. Almedals does not require the use
of any specific products or manufacturers.
Accordingly, follow the care instructions
provided by the manufacturer.
See the National Swedish Flooring Trade
Association's standard formula for varnished: www.golvbranschen.se
See OSMO Hard wax oiled wood floors:
www.welinoco.com
GENERAL ADVICE
Stop the dirt at the entrance. For this reason, you should always have an effective
doormat inside the exterior door and, if
possible, outside as well. Keep the temperature and humidity as constant as possible to avoid excessive movements in the
flooring material. Protect the wood floor
against all types of liquids. Wipe up any
spills immediately. Felt or Teflon (special)
protective pads - but not metal - should be
fitted to furniture.
CLEANING
Make it a regular routine to remove visible
soiling such as dust, crumbs, gravel, etc.
Vacuum cleaning, sweeping, or dry mopping will remove most dry particles. Damp
mopping with a very lightly damp cloth or
mop may be done as needed. Dry mop
immediately afterwards! - Never leave a
damp area on an oiled wood floor. When
you are damp mopping an oiled floor, it is
a good idea to add an oil-refreshing soap
cleaner to the water. Oil-refreshing floor
soap has an oil content of 20-30% and
should not be compared to ordinary yellow
or green soap. A pH neutral cleaning product should be used on varnished floors.
MAINTENANCE OF
OILED WOOD FLOORS
Oil-finished floors should be regularly
maintained. After thorough cleaning, supplement the base oil finish with another
coat of oil that cleans and adds a new
layer of protection to the floor. The first few
times you clean and maintain the floor are
very important in order to quickly achieve
full protection of the floor. The frequency of
maintenance varies considerably depending upon the use of the room. Various suppliers of floor oil offer different solutions for
cleaning and maintenance oiling.
In general, a brown polishing pad used
when oiling with solvent-based maintenance oil is a very effective cleaning
method, which polishes away any raised
wood fibres while adding a new layer
of floor oil. After the oil has dried, dry
polish the floor with a white polishing
pad. Varnished floors can be maintained
with various types of varnish refreshers or
parquet polish.
In public spaces, combined sweeper/
scrubber/drier machines are often used to
advantage with re-oiling wood floor soap.
MAINTENANCE OF
HARD WAX OILED WOOD
FLOORS
regularly maintained. After thorough
cleaning, supplement the base finish with
another coat of hard wax oil that cleans
and adds a new layer of protection to the
floor. The frequency of maintenance varies
considerably depending upon the use of
the room. Various suppliers of hard wax oil
offer different solutions for cleaning and
maintenance oiling.
In public spaces, combined sweeper/
scrubber/drier machines are often used to
advantage with re-oiling wood floor soap.
SPOT REMOVAL
Remove spots before they have dried
into the floor. If necessary, wipe the area
afterwards with clean water. Use a slightly
damp cloth. Excess water, strong alkaline
cleaning products and strong solvents
damage wood floors.
1. Always try a weak soft soap solution
first and rub the spot with a cloth or scouring pad.
2. If necessary, switch the soap solution
for a cleaning product recommended
by the supplier of the surface finishing
system.
DANGER OF FIRE!
Organic materials such as cloths, paper
polishing pads, etc. that have been in
contact with floor oil based on linseed oil
must always be placed in water immediately after use to prevent spontaneous
combustion.
A hard wax oil-finished floor should be
