Laying instructions

Laying instructions
Attention: Read thoroughly from beginning to end before installation!
Celenio is a technically sophisticated product.
To meet the high quality requirements, Hamberger trains and certifies
authorised business partners in the installation of Celenio.
Please note: Celenio must only be laid by installers who have been
certified by Hamberger. Hamberger accepts no warranty or liability for
Celenio flooring installed by any person without such certification.
Required tools
- For laying, grouting and caulking you will need a special spreader L,
tile spacers, a grout float, a grouting sponge, a viscose sponge and, if
necessary, a caulking gun (for silicone caulk).
- To cut Celenio use a circular saw bench with a wood saw blade, a wood
or metal drill, a compass saw, and a square edge.
- For precise measurements use spirit level, chalk line and straightedge.
- Please follow the manufacturers’ instructions and wear safety glasses
and hearing protection.
Type of adhesive
Celenio Special Glue
Adhesive storage: Store in a cool, dry place; shelf life approx. 6 months
when stored in unopened original container.
Grout
Celenio Special Grout
Layout plan for calculating the exact material
requirements
- To determine the amount of material you will need, draw a ground plan
of the areas to be installed on graph paper true to scale. Then include the
pattern in which you want to lay your Celenio floor in the ground plan,
taking the tile size and planned tile joint width into account.
- Use the finished drawing to calculate the required amount of Celenio tiles.
Add approx. 5% (up to 10% for diagonal patterns) since you will need to
cut some of the tiles to size, and add a further 5% to have additional
material handy in case repairs should become necessary some time.
Subfloors
Cement floor, sanded anhydrite floor, V 100 (E1), solidly fixed particleboard
or OSB underlayment. Floating dry floor screed elements, such as
V 100 (E1) or OSB boards must be at least 30 mm thick. Please ask for our
special laying instructions when installing over plasterboard or cement
board. Suitable only for indoor use in well-ventilated rooms.
Testing of subfloor
The subfloor must be tested before laying according to the German VOB
Contract Procedures for Building Works, Part C, DIN 18 356 Parquetry
Works. The subfloor must be dry, clean and even, compression- and
tension-proof, and free of cracks. Make sure the subfloor has been cleaned
thoroughly from oil, grease, wax, paint, plaster, dust and other deleterious
substances that may prevent or reduce adhesion.
- Moisture check
The subfloor must be checked for possible moisture, e.g. by using a CM
measuring instrument.
Limit moisture content:
Cement screed max. 2.0 CM (weight)%, with underfloor heating 1.8% CM;
Anhydrite floor max. 0.5 CM (weight)%, with underfloor heating 0.3% CM;
Always aim for the lowest values!
If necessary, level with appropriate filler or compound according to
manufacturer’s specifications. Do not remove subfloor edge insulation
until levelling and priming has been completed.
- Testing for evenness:
According to DIN 18 365 (surface evenness tolerances according to DIN
18 202).
Follow the instructions of the filler manufacturer. Important: Before
levelling with filler or compound, it is essential to remove excess or
loose quartz sand with a disk sander and then vacuum with an industrial
vacuum cleaner. Anhydrite floors always require sanding or brushing and
subsequent vacuuming. Wood subfloors must be solidly fastened; nail or
screw loose boards, if necessary—the floor must not sag.
- Surface strength:
Use grid scratch test. Do a test panel before gluing down Celenio.
Completely remove all loose parts, deleterious substances and nonwaterproof paints and primers, and make sure the floor is absolutely
clean.
- Daily joints:
Daily joints in the subfloor (pseudo-joints or predetermined breaking
points) must be locked before installation. DO NOT close any expansion
joints.
Measures to take before installation
Store and climatise the cartons inside. New constructions to be closed
in with air conditioning or heating units during the winter months.
Recommended room conditions for installation are 18 °C (65 °F). This
high-grade engineered and dried product should not be stored in new
constructions.
- Acclimate Celenio to the jobsite in the unopened cartons for at least 48
to 72 hours.
- The ideal room conditions for installation are between 18° C and 22° C
(64° F and 72° F) with a relative air humidity of 40% to 65% prevailing in
the room for at least 5 days prior to installation.
Important: Prior to installation, inspect the boards in daylight for any
visible faults or damage and also check colour and texture. No claims
are accepted once flooring boards have been installed. When installing,
mix Celenio boards from different cartons.
Colour changes may occur from exposure to light;
Before starting installation, decide the best direction to lay Celenio based
on the surface texture.
Glue-down installation
Do not glue down if ambient temperature is below 18° C (64° F). To avoid a
high relative air humidity in the room (such as in new constructions), heat
the room if necessary and ventilate thoroughly. The relative air humidity
should range between 40% and 65% and the subfloor temperature should
be between 16° C and 22° C (61° F and 72° F). approx. 1000 – 1200 g/m².
Apply with the notched Special Spreader L with 5.5 mm deep notches
which is included in the range of accessories. We recommend that you
keep Celenio in the original cartons until immediately before glue-down..
Also follow the instructions of the adhesive manufacturer. Wait about 24
hours after installation before first use; Heavy traffic or loads only after
about 72 hours.
Recommendation: The information given here is based on experience
and serves to advise the person doing the laying. We can supply only
general indications since the proper workmanship is not under our
control. Make a gluing test before installing the floor or, if you are
uncertain, ask a professional installer to lay your floor.
Grouting the floor
- Allow the Celenio Special Glue to cure completely before grouting.
- Clean the joints thoroughly.
- Do not grout expansion joints (5 - 10 mm). Cover them, for example, with
adhesive tape before grouting.
- The required amount of Celenio Special Grout depends on the joint
width. Please observe the directions on the bag.
- When cleaning the floor surface take care not to get too much water into
the joints.
Caulking expansion joints and control joints
- Joints that are subject to mechanical movement need to be filled with
permanently elastic silicone caulk. This silicone caulk is available in a
wide range of colours.
- Remove glue residue and dirt from the joints immediately.
- Cut off the tip of the silicone caulking gun according to the width of
the expansion joint. Apply silicone caulk evenly into the joint with the
caulking gun.
- Smooth out the fresh silicone caulk with the fingertip or a putty knife and
a few drops of dishwashing detergent diluted in water.
Celenio over underfloor heating
If the following instructions are observed, Celenio glues down easily over
underfloor heating systems without problems. Celenio has a favourable
thermal resistance (1/λ=0.024 m² K/W) for an economically efficient
running of the heating system: Due to the natural foot warmth of the
floor, the underfloor heating system can be switched off more readily than
with ceramic floors, even during transition periods. And with Celenio over
underfloor heating systems, a uniform surface temperature is attained
besides (max. surface temperature 25°C/ 77°F).
Preparatory measures with newly installed underfloor
heating systems:
- The subfloor must be laid professionally as per German Standard DIN
18 353. In this regard, also comply with the instructions for heated
floor constructions issued by the Central Association of the German
Construction Industry. The curing time before starting the preparatory
heat-up phase which makes the subfloor ready for laying the floor
covering is generally at least 28 days for cement floors and at least 14 days
for anhydrite floors. The subfloor is ready for laying the floor covering
when the CM measurement shows a moisture value of 1.8 CM % for
cement floor and 0.3 CM % for anhydrite floor. Locking of pseudo-joints
and cracks in the subfloor by means of two-component artificial resin
is imperative for glue-down installation of the floor covering. Expansion
joints provided by the heating manufacturer must be taken over in the
floor covering as well.
- During the preparatory heat-up phase for laying the floor covering, raise
the flow pipe temperature by 10°C (50°F) each day, starting from 25°C
(77°F). Increase the temperature until the maximum heating temperature
of 55°C (131°F) – or the system maximum if less than 55°C – is reached.
Do not lower the temperature during the night!
- Heat for 11 days without interruption at the maximum system temperature
or at 55° C (131° F), respectively; do not lower the temperature during the
night.
- Reduce heat by 10° C (50 °F) daily until temperature drops to 25° C (77° F)
(still do not lower the temperature during the night).
- Now test the subfloor for moisture by using a CM measuring
instrument.The measurements must be taken at the designated
measuring points. If this test shows that the subfloor is not yet ready
for laying the floor covering, continue heating at a flow temperature
of about 40° C (104° F) until the subfloor has the limit moisture content
required for installation.
Preparatory measures with newly installed underfloor
heating systems:
With warm-water type underfloor heating systems that have already been
in use for several heating seasons, we recommend—before installing
the floor covering—to raise the flow temperature to 45° C (113° F) and
maintain this temperature for one week without interruption, and then
reduce the temperature again to 25° C (77° F). Please note: Covering
the Celenio floor surface with carpeting may raise the heat transfer
resistance and cause an accumulation of heat.As it is impossible to
take into account the entire vast range of underfloor heating system
products, please address any inquiries to our authorised dealer or to the
manufacturer of your underfloor heating system.
Care Instructions for Celenio
Dry cleaning
It is generally sufficient to clean Celenio dry using a mop, soft broom or
vacuum cleaner. For especially effective dry cleaning we recommend our
special HARO Easy Clean cleaning cloth.Heel streaks or grease stains can
be removed with HARO Stain Remover or acetone.
Damp cleaning
We recommend that you regularly damp mop your Celenio floor with
diluted Celenio Basic Cleaner, according to how dirty the floor is and wear
and tear. Add approx 150 ml (approx. 3/4 cup) of the floor cleaner to 8 -10
litres of water (1 bucket). Then wipe the surface damp with a well wrung
out cloth. By buffing the treated surface dry with a HARO Polishing Cloth
you give the Celenio surface an even shine.
Please note: Do not use soap-based detergents, abrasive cleaners,
scouring powder, steel wool or wax for cleaning and maintenance.
Always avoid letting water stand on the laminate floor surface.
Warning note: Steam cleaning machines are not suitable for cleaning
Celenio.
Room climate
- The conditions specified above must be maintained for at least another 5
days after the floor covering has been installed.
In order to maintain the quality and beauty of Celenio, but also for your
own personal well being, an indoor climate of approx. 50% -60 % relative
air humidity is necessary with a room temperature of approx. 20º C. In
order to keep the air humidity constant, especially during hot periods, we
recommend you use a humidifier. This will prevent any extreme drying
out of the floor. It is advisable to use an electric humidifier right from the
beginning of the heating period.
- The underfloor heating can now be run during the heating season.
Additional preventive protection
Important: Failure to comply with the ” Preparatory measures ... ”
given in this ” Underfloor Heating ” section will void the manufacturer’s
warranty for the product. We cannot assume any liability unless the
heat-up record is properly filled out and signed!
To preserve the quality and beauty of your floor we recommend using
protective pads under chairs and furniture legs. The castors of armchairs
and office chairs must comply with German Standard DIN 68 131. Use only
lined rollers of type W (soft). It is also a good idea to use polycarbonate
mats as underlay for armchairs and office chairs.
- You can now install your HARO Quality Flooring: Observe the above
laying instructions: The surface temperature of the subfloor during
installation must be at least 16° C (64° F) and the relative air humidity
must be < 40–65%.

Laying instructions for Celenio with glue-down installation
Attention: Read thoroughly from beginning to end before installation!
Please always comply with the installation instructions that are enclosed with the cartons. The accompanying instructions are binding!
햲
Installing Celenio in the room
Check the room layout before you
start to instsall Celenio. In rectangular
rooms, snap one chalk line down the
centre of the room and one chalk line
parallel to the wall, at a right angle to
the first chalk line. Align the first row
of Celenio with the chalk line. At the
point of intersection of the two chalk
lines, start either with a joint or with
the tile centre. The joints between the
Celenio tiles may be 3 to 8 mm wide.
Choose the joint width you want to
use before starting installation and
maintain this width throughout the
installation. To ensure even joints,
we recommend using suitable tile
spacers. Leave an expansion space
of min. 10 mm around perimeter.
햶
The next Celenio rows are laid along
the centred chalk line.
햺
If a grout haze has remained on the
surface, wait one day before wiping
it off with hot water and a microfibre
cloth; to remove strong grout haze,
use Celenio Clear Finish (follow
instructions on label). Any grout
residue must be removed completely.
햳
Glue-down installation of Celenio
Apply the Celenio Glue to the floor.
Work in sections, starting from the
chalk line. Always ensure 100%
adhesive coverage. The best way
to spread the adhesive is to use a
special spreader L (5.5 mm notches).
Please observe the open time of the
adhesive (the time during which the
adhesive can be used). Only apply
adhesive for the area you can install
before the adhesive starts to set or
dry.
햷
When installing Celenio in
adjoining rooms ensure continuous,
uninterrupted tile joints. Provide
joints/expansion joints exactly
under the door leaves; also, observe
expansion joints provided in the
subfloor. Expansion joints in the
subfloor must be maintained in the
floor covering as well. When installing
the floor covering in rooms measuring
over 10 m in length or width, you
need to leave an expansion gap of at
least 5 mm. Seal the expansion gap
with a colour-matched silicone caulk.
햻
Celenio skirting
To install Celenio as a tile skirting, you
can use construction adhesive which
is available as a glue gun. Gypsum
plaster residue or old loose paint or
plaster need to be removed from the
skirting area. Touch up the surface to
be adhered to, if necessary.
햴
Lay the Celenio tile into the wet
adhesive and press on. This spreads
the adhesive evenly across the
back of the tile. Align the first row
of Celenio with the chalk line. For
exact alignment of the joints, you
can insert tile spacers between the
Celenio tiles which you can remove
after installation (do not bring into
contact with the adhesive). Important:
Remove adhesive stains on the
floor covering immediately with
methylated spirit.
햸
Grouting of Celenio
Before grouting, dampen up to
1.5m² of the area to be grouted with
a slightly damp viscose sponge.
Take ready-to-use grout from the
container and grout the 1 - 1.5 m²
large dampened area with the Celenio
rubber margin trowel.
햵
At least 90% of the tile back should be
covered by adhesive. To be sure, lift a
tile to check adhesive coverage while
the adhesive is still wet. Then reinstall
the tile with fresh adhesive.
햹
Moisten any excess grout material
with a slightly damp viscose grout
float in a circular motion. Immediately
after grouting, wipe the area
diagonally with a well-wrung Celenio
viscose sponge (use clean, hot water).
Repeat this process several times.
After taking up excess grout, smooth
out the joint with the slightly damp
Celenio viscose sponge / grout float.
