PLEASE NOTE:
This product is considered a professional product and requires a
high degree of technical ability to be installed correctly. We always
recommend a qualified and experienced professional should be
responsible for the installation of this product.
PRE INSTALLATION
Crown Engineered Wood Flooring is a natural product and
acclimatisation is required to ensure the best possible results.
However, the warranty conditions dictate that the Engineered
Wood Flooring is to remain in the sealed packaging before the
date of installation.
SUBFLOOR PREPARATION
This type of flooring is suitable for installation on most types of
flooring substrate, as long as its clean, dry and level (e.g. sand
and cement screeds, timber floorboards, chipboard, plywood
are all suitable). It is the responsibility of the flooring installer
to check that the site condition is in a satisfactory state for the
installation to take place including all moisture related readings.
Concrete & Screed Sub-floors
It is vital that the installer checks the moisture content of the
concrete/screed to satisfy themselves that it is dry enough
for the installation to commence. If measured directly with
an appropriate moisture meter, the moisture content should
not exceed 4% on a non-destructive moisture meter such as
Tramex / Gravemetric weight percent measurement (2.5%
CM for Concrete screed / 0.5% CM for Anhydrite screed)
and the relative humidity of the air over the floor screed and
should be between 45-65% R.H. @ a temperature of 18-21ºC.
The floor screed must be leveled before installation to a
tolerance of no more than a 3mm gap showing under a
3m straight edge.
Timber Sub-floors
Floorboards, O.S.B, plywood and batterns are all suitable sub-
floors for Crown 18mm Engineered Wood Flooring.
If your sub-floor uses chipboard, we recommend stabilising
this using a minimum of 6mm plywood before installing your
Engineered Wood Flooring. The same level tolerance of
3mm applies.
Please Note: If installing on existing T&G flooring, make sure
all old floorboards are secure and free of infestation. We also
recommend that your new flooring is installed at a 90º angle
to the previous T&G flooring, as this will provide the necessary
stabilisation required should any subsequent movement of
either of the timbers occurring.
PRODUCT USE
Crown 18mm Engineered Wood Flooring can be installed:
- On or above ground level (not suitable for use in
basements)
- In well ventilated and dry areas, providing the area falls in
line with the Climate Control section of these instructions.
- Installed using the Fully Bonded or Floating installation
method
- Over a plywood, concrete sub-floor or directly onto joists.
- For use with Underfloor heating systems (Please refer to
the Underfloor Heating section within these instructions)
This floor should
NOT
be installed in bathrooms or laundry
rooms or other areas with high humidity. Use in any of these
applications will void the product warranty. Crown Engineered
Wood Flooring is designed for indoor use only.
PLEASE READ THESE INSTRUCTIONS COMPLETELY
BEFORE BEGINNING THE INSTALLATION.
The following instructions must be used to install Crown
Engineered Wood Flooring. Failure to do so may result in
voiding the product warranty.
INSTALLERS / OWNER’S RESPONSIBILITY
At Crown Floor, we only use the best natural materials to
manufacturer our flooring. As wood is a natural product, you
can expect changes in colour, grain and appearance and other
visual imperfections between each of the boards - No two
planks will have the same characteristics. We manufacture our
products by following the accepted industry standard which
outlines that defective boards must not exceed 5% of the
full pack. These defects may be the result of manufacturing or
naturally occurring characteristics of the material.
We recommend that a minimum of 10% for cutting and
5% for visual grading should be added to your total square
meterage when calculating the quantity of flooring required.
Please Note: If your room is not of equal proportions, the
percentages of waste may be different to what we have
outlined above - This is an approximation.
Before the installation begins; it is the joint responsibility of
the installer and owner/customer of the site to conduct a
thorough site inspection before any flooring is installed.
When carrying out the pre-installation inspection, please
pay close attention to the following aspects:
- Quality of Manufacturing
- Finish
- Colour Grading
