DAUERHOLZ patios made easy
Please follow our installation instructions to ensure that your
DAUERHOLZ patio gives you many years of pleasure.
Substructure
Fig. 1: The base should be laid
with regular spacing.
Incline
Fig. 2: The incline should be at
least 1 per cent.
Cutting decking to length
Fig. 3: DAUERHOLZ chips can be
slippery – do not cut decking in
the vicinity of the patio surface.
Screwed connections

DAUERHOLZ decking.
Sinking the screws

Always use the same type of wood for the base and patio decking.
For 21 mm decking (thickness), we recommend 40 cm
spacing between the DAUERHOLZ base planks and max. 50 cm
for 25 mm decking. 42 mm decking permits maximum spacing
of 80 cm.
Please ensure surface water drainage by forming an incline
towards the wood grooves and away from the building. The
incline should be at least 1 per cent – otherwise water after rainfall
can pool on the surface for disproportionately long periods
when laid horizontally. This can encourage the formation of algae
and discoloration on the surface. In any case, waterlogging under
the base must be avoided. The use of spot supports (e.g. made
of stone or Isopats) extends the life cycle of your patio.
DAUERHOLZ is impregnated with wax through to the core.
When cutting DAUERHOLZ decking, the chips incurred can form
a slippery film on surfaces owing to the wax contained therein.
Avoid slipping by cutting decking in a separate, less-frequented
area (e.g. lawn).
DAUERHOLZ is very stable – please pre-drill decking wood. We
recommend using V2A stainless steel screws. Other screws of
inferior quality can cause discolouration of the wood. Please
use two stainless steel screws for each contact point on all
DAUERHOLZ decking when securing decking to the base. The
space between screws and the edge of decking wood should
be 20 to 25 mm while screws should be positioned 5 to 10 cm
from the end of each plank.
A sunken screw head acts like a funnel for rainwater. Water
can pool there for particularly long periods of time. Such funnels
can also swiftly accumulate dirt, algae and fungi deposits
which can lead to discoloration of the wood after only a short
time. The screw heads should therefore be flush with the wooden
surface.

Protecting your

patio is installed properly.
Depending on the respective width of DAUERHOLZ decking, the
installation join should be selected as follows:
90 mm 5 mm 6 mm
115 mm 5 mm 6 mm
130 mm 6 mm 7 mm
140 mm 7 mm 8 mm
145 mm 7 mm 8 mm
The spacing between joins where decking meets should be at
least 3 mm.
Please note that many securing systems specify spacing between
joins which is too tight and therefore not suitable for securing
DAUERHOLZ. We recommend the DAUERFIX installation system
for concealed securing. This system has been especially co-ordinated
for working with DAUERHOLZ decking. DAUERFIX is exclusively
aligned towards decking which is min. 25 mm thick.
As a general rule, the following applies: wax impregnation ensures
durability of the wood. You can however change the colour
of DAUERHOLZ after installation, whereby you can choose between
eight different DAUERSCHÖN + colours. In order to retain
your chosen colour over several years, you should treat the wood
before and after the season using DAUERSCHÖN + oil. Please use
our DAUERFRISCH brightener to refresh grey DAUERHOLZ. Please
only use DAUERHOLZ products for maintenance. They have been
specially developed for waxed wood. If you wish to clean the patio,
please do not use a high-pressure cleaner – the soft spray of a
water hose is sufficient.
Soiling of the wood by metal and stonework (angle grinding, drilling,
polishing) can cause discoloration when combined with water
(reaction between iron and tanning agents). This reaction is visible
in the form of dark spots on the wood (not only on DAUERHOLZ).
Abrasion caused by angle grinding discs can also affect the wood
(e.g. passed on through work clothing) where it can cause colour
reactions. Ideally, woodwork is performed after all other tasks have
been completed. If this is not possible, the patio should be covered
over. Please exercise care when handling lawn fertiliser which can
also contain iron oxides while garden furniture and accessories
made of iron can also cause stains.
