Fix the mountings to structural, finger jointed,
double layer glued joists of 50 x 60 mm, preferred
lengths 3 metres from acacia or sweet chestnut,
spanning 4 joists. Pine or fir is not a preferred
base due to its relatively short life in hostile
environments. The set of aluminium mountings
are supplied inclusive of 100 pieces of stainless
steel screws, matched to the channelled edges,
sufficient for about 6 m 2 of decking, based on
spacing between the joists of 50 cm (maximum
80 cm).
Acacia is the hardest wood and most suitable
for external constructions, being the hardest of European woods and thereby most suitable for outdoor
constructions (category level 1).
The finger jointing is completed with specially developed glue suitable for external constructions, resistant to
high and low temperatures and damp or dry environments. For maximum satisfaction and enjoyment from
your terrace decking for many years to come, we recommend that you treat and protect your decking once
or twice per year with proprietary terrace decking oil.
As a basis you can also use aluminum profiles with mounting feet X-Step or CAT-Step.

PRACTICAL INFORMATION AND TIPS
FOR LAYING SOLID WOOD FLOORING
General information about caring for solid wood flooring
Flooring boards must be stored in a dry and moisture free area. The binding must be released
and discarded only immediately prior to laying the wooden flooring. The wrapping can be
discarded at time of delivery or at the time of storing to help the boards acclimatize to the
room conditions.
Installation of the flooring must be made only after the completion of all other associated
works, bricklaying, decorating, plumbing, electrical work, painting and tiling.
Before and during installation, it is preferable to warm the room where the flooring is to be
installed to 18 – 20 °C and relative humidity at 50-60 %. Health environment is important not
only for flooring but also for your general well-being. For best sustainment of the room
climate, these conditions should be met, especially during the winter months when central
heating can often reduce the relative humidity to below 45 %.
Flooring boards should be checked in advance of laying the floor, for general flatness, evenness
and any obvious faults (in the unlikely event of some manufacturing error or omission) to
achieve ideal results of the finished product. Wood is a clean and natural product and its
natural colour, structure and features are determined by nature. Wood is an ever changing,
living material which will expand during periods of higher humidity or moisture content and
equally, shrink as a result of lower moisture content. Raised areas, such as knots in the structure
and colour abnormalities or deviations are typical in this product and should not be the
reason for any warranty claims. The choice and selection of suitable planks is determined
in-house at our factory by our highly experienced craftsmen.
We cannot emphasize enough, the importance of the room climate. We highly recommend
the room temperature be maintained at around 20 °C with a relative humidity of 50 % and
it is important to watch this and try to keep these conditions consistent. If there are large
fluctuations in these parameters, you may well experience gaps between the boards and
some warping but this is not necessarily permanent. However, long term differences in optimum
temperature and humidity can result in permanent changes to the flooring and therefore
should not be the reason for any possible warranty claims.
General recommendations for laying floor boards
Before laying, substrate must be fully completed and controlled according to the general
rules valid for the construction, for example conditions regarding the fixed areas and dryness,
free of cracks and contamination. Installation must always begin at the walls and with leaving
gaps of 12 to 15 mm for temporary wedges. Always begin with the groove to the wall (not
the tongue). Lumps or bumps in the wall may indicate disparities in the necessary width of
the wedges, in the longitudinal direction and be aware that it may be necessary to trim the
edge of the beginning board, according to the profile of the wall, to maintain the necessary
wedge gap. Attention should be paid to squareness of the room and the relative laying of
the boards, also according to the squareness of the cut ends. We produce floor boards with
tongue and groove around all their edges and thus they can be laid in endless rows where
the initial piece connects perfectly with the next, consecutive, piece. The subsequent row
should be laid, not in line with the first board but with an overlap of at least 30 cm. from the
end of one row to the next row.
The above procedure also helps ensure a minimum of waste. The final row must also be cut or
trimmed again to maintain a 12 to 15 mm gap for the temporary wedges between the edge
and the wall. For best results, tightening straps should be used during the laying process, up
until the final row is laid and held in place by the wedges. After removal of the wedges, the
skirting boards can be fitted but ensure the skirting boards are only fitted direct to the wall
and not to the floor! Solid wood flooring must never be laid on electrically heated floors due
to the rapid and localized raising of the temperature!
3 2
FITTING PROCEDURE
Fitting by screws
Floor boards should be laid on a dry wood base (support) in a span of 40 – 60 cm or directly
on the existing floor (or chipboard type under-floor panels). Please make sure that all base
materials are dry (max. 12 % relative humidity). If desired, boards can be installed on top of
a suitable variable moisture vapour barrier. Foil vapour barriers must overlap the side wall to
a height of 10 cms and by 20 cms from the end of one barrier to the next barrier. When fitting,
the excess part can be trimmed with a sharp knife. Floor boards laid should be tightened from
one to the next using tightening straps and screwed to the floor through the floor board tongue
only, at an angle of 45 °, into the underlying beam or support floor. Recommended screws
are 3.5 x 50 mm or 3.5 x 60 mm. The first row of boards may be screwed through the face
at a suitable angle, in such a suitable location that the screw head will later be covered by
the skirting boards. Individual screws should be concealed by drilling suitable holes with a
countersink, to accommodate the screw heads. Fitted screws must obviously not impede the
close fitting of the next row of boards at the tongue and groove connection. Any impediment
may cause gaps and distortion of the final effect.
Fitting by glue
Floor boards can be mounted on any professionally prepared base (cement, dry mix, cast
asphalt, plywood, chipboard, OSB boards etc.) by help with glue. Floor boards prior to
glueing should be left in the room with a temperature of 15 – 25 °C with a relative humidity of
40 – 50 %. The temperature of the base should be minimum 15 °C, maximum 25 °C in the case
of where under floor heating is installed, with a surface temperature of 20 °C . Residual moisture
content of cement floors should be within 2 %, 0.3 % for air drying mortar and 12 % for magnesium based mortar preparations. In these cases, apply the glue by smearing across the whole
base in such quantity that allows you to work within the setting time of the glue. Use a glue
spreader with a tooth gap according to the recommendations of the glue manufacturer.
For further information, check with the glue manufacturer of retailer. Surplus glue and glue
deposits on the upper side of the floor boards must be completely removed before the glue
hardens. The first and last line of the floor must be suitably weighted during the hardening
state to maintain flatness and best adhesion.
Laying of floating floors
Solid wood flooring should ideally not be used in a floating floor type of installation. The floating
type of installation must be conducted so that the base concrete floor vapour barrier must first
be placed and subsequent materials following with respect to noise insulation materials such
as felt, cardboard, felt etc. (according to the supplier’s instructions). Lay the boards directly
on the substrate and pay attention to the individual floor boards which should be glued
together at the tongue and groove. The most suitable bonding glue is the fast drying type.
For this kind of laying, it is necessary to use tensioning belts in order to obtain a perfect
connection. Ensure sufficient glue is used and clean any residual or squeezed out glue before
it sets. Do not fix any board to any wall. Floating floors should be permitted to move, or “float”
in any direction, during natural expansion or contraction.
General information about oiled floors
Wood lives. Oiled wood provides a more comfortable environment and indoor climate.
Wooden flooring can cover the differences between those periods of higher and lower relative
humidity. Oiled surfaces are also very robust and resilient to dirt. To help protect the surfaces
against scuffing, scratching and excess wear, always try to install a suitably located cleaning
zone (door mats) to catch dirt and moisture immediately outside the room door.
This is particularly important when using coloured floors. Table and chair legs should always be
fitted with sliding pads or felt protectors. Also, where necessary, ensure the bottom of doors
are adjusted as necessary to prevent scraping, by a combination of trimming and/or raising
the hinge positions.
Further information about oiled floors and maintaining them can be obtained from the Overmat
company brochure or check their website www.overmat.nl.
3 3
Solid wood and under floor heating
If you opt for wooden floors in rooms with under floor heating, you should incorporate the
following conditions when making the selection, installation and maintenance of the flooring:
1. The ONLY possibility is to use low-temperature warm water under floor
heating. It is not possible to use electric heating mats due to their extremes of heating time
and thermostatic range.
2. The selection of wood species is important. Due to temperature fluctuations, opt for wood
which has slow and small response to temperature differences. Such suitable woods are
oak, acacia, jatoba, mosaic parquets and 3-ply floor boards. Unsuitable woods are beech,
ash and maple.
3. If using solid wood flooring, the thickness should be 15 mm maximum and the widths and
lengths should be kept to a minimum.
4. There are large differences in sizes between solid floor boards and a solid ply-wood floor
in the long and short boards and thin and thicker boards. Recommended woods are, for
example, oak 15 x 105 x 500 until 1200 mm and acacia 15 x 102 (125) x 500 until 1500 mm.
5. If using under floor heating, you MUST only use the glued type of installation. It is most
important to heat the floor before installation of the floor boards, according to the
plumber or recommendations of the glue manufacturer or retailer.
6. Important: There must always be complete adhesion of the glue.
Prior to laying the floor boards, the boards must be heated to the ambient room temperature.
Glue must be flexible and designed for installation directly on the floor heating. Later cleaning
and maintenance should only be used in accordance with the manufacturer’s recommendations. When mopping the floor, only use a lightly dampened cloth.
It is recommended to have an internal room temperature of 200 °C and relative humidity
of 55 %. Significant variations can occur in warping of boards and propagation of gaps or
cracks. A long-term decrease in humidity can result in irreversible damage to the boards.
Wood Hardness
There are soft, medium and hard woods. Soft woods are such as Spruce, medium woods are
such as Birch and European Maple and Larch, hardwoods are such as Canadian Maple and
Acacia.
The hard woods are not necessarily the best for outside constructions (damp areas) such as
terrace decking. Whilst Sweet Chestnut is certainly not considered to be a hard wood, it is
however ideally suited for external constructions.
The method for measuring the hardness of wood is the Brinell test. This method was developed
by the Swedish engineer J.A. Brinell, in connection with the World’s Fair in Paris in the year
1900. The procedure of this test is based on the pressing of a steel ball with a diameter of
10 mm, with a gradual increase in the load for 30 seconds on the wood sample with a humidity
of 12 %. The Brinell value is determined by the subsequent size of the indentation in the wood
surface. The higher the Brinell value, the more durable and resilient will be the wooden floor.
