Drylining and Parge Coating ...
Introduction
The
external walls of the majority of
buildings are normally formed from masonry (e.g. concrete blocks,
bricks or stone). The interior surface of the masonry needs to be
finished to even and smooth finish that can be either painted or wall
papered.
In the past, the majority of masonry walls were finished by applying
several coats of sand and cement render to even out the wall, followed
by several coats of plaster to give a smooth surface. This method is
most commonly referred to as solid plastering.
In recent years solid
plastering has largely been replaced by
drylining
(also known as
Drywall
or
Dot
and
Dab).

Drylining
In the
Drylining
method sheets of plasterboard are attached to
the wall
using a special plasterboard
adhesive made from gypsum.

Example of a typical Drylining of a Wall
This method is known as
drylining
because it
requires far less water than traditional sand and cement renders used
in solid plastering. The advantages of
drylining over solid plastering are:
- A warmer building - drylining
has better
insulating properties
than solid plastering.
- Quicker and cheaper
construction - it is quicker and therefore
cheaper to make the wall true and plumb using drylining
than it is
using solid plastering.
- Quicker drying out times -
because less water is used in drylining
it is quicker to
dry out than solid plastering and therefore
quicker to start decorating.
Drylining
allows services such as cables and pipes to be concealed with
the minimum of wall chasing.
When
drylining
the ceiling is normally fitted before the wall is
drylined.
Typically, drylining is started at a window, door or internal angle. A
continuous fillet of
Drywall
adhesive is applied around the perimeter
of the wall and around all services and openings. This is to ensure
that the lining is air tight to achieve air tightness required by
Building Regulations. For the first plasterboard a further 2 rows of
intermediate
Drywall Dabs
are applied to the wall. The first plasterboard is then fitted in place
and held tight against the ceiling. The board is tapped lightly to get
it plumb. Subsequent plasterboards are fitted in a similar manner using
3 rows of intermediate
dabs.

Plasterboards for Drylining
A range of plasterboards can be
used in Drylining:
- Thermal Plasterboard
- a plasterboard which has a layer of insulation bonded to it for
increased thermal properties.
The plasterboards can then be finished using either traditional
Plastering
methods or
Taping and
Jointing.
Typical
uses of drylining
- Finishing of masonry walls
in new builds, extensions and
conversions.
- Re-lining of old walls when
the old plastering coats have failed and
been stripped off.
- Making good after
alterations (e.g. window fitting, moving
doorway ).
- Lining the walls after a
conservatory has been erected.
- Truing up walls (e.g. for
tiling, bathroom and kitchen fitting)
Sound
(Parge) Coating
If required, Regency Construction can
increase the soundproofing, thermal performance and air tightness
of a masonry
wall prior to installing drylining by applying a special sound proofing
plaster known as
Parge Coat.
Parge
Coating can improved energy
and acoustic
performance, lower heating costs, reduce CO2 emissions and provide
greater comfort for its occupants.
Parge
Coating is commonly used on
Party Walls (Walls that are shared between adjoining buildings).
