UNILIT 1320 (TD 13/20)
MASONRY MORTAR POINTING AND BEDDING DESCRIPTION
UNILIT
1320 is a mortar based on natural hydraulic lime and silica sand, of a maximum
granulation of 2 mm. The
granulometric curve is ideal (Füller curve).
UNILIT
1320 is particularly suited for the restoration of old masonry and brickwork but
is suitable also for use as a mortar for laying stone, block or brick in new
construction. APPLICATION
The
natural composition of UNILIT 1320 limits the soluble salts content in the
mortar which in turn reduces efflorescence and lime bloom on the surface of the
masonry. The
materials are extremely flexible and simple to use. TECHNICAL PROPERTIES

Beige PREPARATION
The
substrate must be clean and free of all traces of oil and grease.
When the substrate has been treated with an impregnating product
(silicone and similar) it is recommended to consult the supplier or
manufacturer. UNILIT
1320 mixes with clean water. Depending
on the temperature and substrate 4 to 5 litres of water are mixed with 25 kg of
powder. Mix the mortar with either
a concrete mixer or mechanical whisk for a sufficient duration to achieve a
creamy consistency which will be naturally light and viscous.
Existing
surfaces must be clean and provide sufficient key for the mortar.
The
material must not be used if the wall or stonework has been saturated by
rainfall, since this will affect the bond of the material or reduce the
waterproofing qualities of the mortar itself. The
mortar must not be applied in temperatures below 5°C and must be protected
against frost for the first 48 - 72 hours. Equally avoid working in extremes of
heat as this will require light and periodic dampening of the curing mortars. CONSUMPTION

In
case of doubt regarding the substrate, consult our technical service department.
The material must be stored dry and frost free above ground. The maximum storage
time is 6 months. Our advice and information is given in good faith and
depending on the latest developments of our products. We guarantee the constant
quality of our products, but do not accept any liability concerning the
application. !!
