External Applications
DELTA®-PT ccan be used externally as a
waterproof support for rendered finishes,
especially in exposed situations, where
elevations of the building are subjected
to water penetration, salt laden air
(chlorides), or just in need of a ‘face lift’.

Where a traditional finish is specifically required a 6:1:1 sharp sand, cement, lime mix can be applied. This will require expansion joints to minimise cracking. This is applied in 3 coats. Fixing centres should be reduced to 150 mm for external rendered applications.

Alternatively, polymer modified render
should be applied. This will give a
decorative finish which will not need
painting. The render is polymer/fibre
modified, and has been extensively
tested for external use on DELTA®-PT or
DELTA®-LATH.
Polymer/Fibre modified render also
eliminates the need for extensive
expansion joints, normally associated
with this type of application, other than
what is required to meet
building regulations.
‘Fast Track’ application is
achieved using DELTA®-PT or
DELTA®-LATH with polymer/fibre
render as the finish. This allows
subsequent coats to be applied
sooner, eliminating lengthy drying
times between coats.
