A substrate should remain stable and be
provided with any expansion, contraction
and crack inducement joints as necessary.
Before the final treatment to bring a subfloor up to the
standard required for the application of floor coverings to
begin, the condition of the base must be investigated and
any necessary treatments or repairs carried out. Failure
to do this increases the potential for premature failure,
which is counterproductive and expensive to rectify.

Where application involves questionable substrates the
installer must exercise extreme caution and advise the
client of the attendant risks involved.
BS 5325 - Installation of textile floor coverings.
Code of practice.
Old or new substrates contaminated with oil, grease, fat
or chemicals, faulty concrete, inferior grades of concrete,
floors with large cracks or crevices, poor asphalt and tiles
are not satisfactory bases for the application of most of our
products. Some severe conditions cannot be corrected by
normal preparation techniques and the only remedy may
well be to uplift and relay the complete subfloor.
Any substrate forming the base on which an F. Ball
product is to be applied should be designed to withstand
all structural, thermal and mechanical stresses and loads
which will occur during service. A substrate should remain
stable and be provided with any expansion, contraction
and crack inducement joints as necessary. Cracking,
unevenness and faults in the substrate may be reflected
through the surface treatments and floor coverings.
It must be acknowledged that any shortcomings or
failures in a subfloor could lead to a premature failure
of the new decorative floor covering.
