A waterproofing, self-leveling floor screed,
approximately 2-5mm thick, used as a damp resistant layer for old
floors. This will require a latex screed before the finishing layer
A vinyl floor finish with integral foam.
Traditional Axminster and Wilton style carpets
do not tend to have a bonded foam underlay and the traditional way
to smooth out base floor irregularities was to use a felt. This has
largely been superceded by rubber foam although felt often has better
sound absorption qualities. Felt will need paper as a first layer.
Under layers are important and will prevent some wearing.
screed. Generally a hard cement / sand layer but only measuring about
15-25mm. This is laid wetter than screed and with strength throughout
instead of just on the surface so that it can be used as a wearing
surface, particularly in garages.
battens around 25mm wide with small nails protruding 'hedgehog style'.
These are laid spike up around the perimeter of a room to grip the
edge of a carpet.
|LATEX SELF LEVELLING
A mixture of fine aggregate and liquid rubber
poured onto a floor to run and find its own level, thereby filling
any small holes or slightly off-level areas. Around 6mm is the maximum
traditional mixture of cork dust or wood dust, flax, chalk and linseed
oil which is highly compressed between rollers onto a jute backing
and used as flooring. Lino is produced near Dundee in Scotland.
Floorboards are unsuitable for sheet flooring
materials, as the joints will show through. This is prevented by over
boarding with plywood or with pre-soaked or oiled hardboard. Pre-soaking
with water is important to prevent expansion 'bubbling up' the boarding.
coarse, washed sand, sometimes granite based and referred to as 'grano',
which is mixed with cement when slightly damp and spread over a floor
to about 65mm then steel trowelled smooth. The screed may be laid
over a concrete floor a day or so after setting and monolithically
bonded to the concrete by pouring liquid cement (grout) over as glue.
mixture of white cement and marble chippings/powder, laid wet then
ground smooth. This is often seen in shop doorways but can also be
used for work surfaces and basins.
A finishing floor tile of hard vinyl plastic
that, in the past, was mixed with asbestos fibre. For this reason,
20-year-old marbled plastic tiles should be treated as suspect.
