Telling Lime - Natural Hydraulic Lime
Telling Lime manufacture and are distributors for a range of natural lime mortar products for
various applications, together with stabilisation and consolidation grouts, mesh
reinforcement and lime paints and finishes. The natural hydraulic lime products
replicate the strength,
porosity, adhesion, vapour permeability and flexibility of historic mortars.
Unilit mortars conform to European Standard ENV 459-1 for natural
hydraulic lime mortars. The products are
manufactured using a modern day manufacturing process, are guaranteed against failure for 10 years and are warranted against defect
under a professional indemnity insurance.
Telling also manufacture a range of bonding agents for use with Unilit mortars.
Unilit 35M.
A traditional, dry, premixed mineral and finishing mortar based on hydraulic,
naturally pure and selected lime, characterised by a high plasticity, slow but strong
bonding and a low salt content.
Unilit 35M is very vapour permeable and is completely compatible with the Unilit system as
an undercoat or as a finishing layer, for internal and external use providing that
excessive damp or salt problems are not prevalent. Recommended for the renovation of old
buildings.
The product must be decorated with a protective lime based coating to make the
system weatherproof.
A colour finish can be applied with a lime paint - Corical - Lime
wash and lime paint finishes are available from Telling Lime. Alternatively a
through coloured finish - Unilit 65f/65M/65N or a Telling
Cori polished finish can be applied.

Consult Telling technical service department for advice on the suitability of the
substrate.
Consult with Unilit technical literature for details. Natural hydraulic lime mortars are
specialist products and it is recommended that Telling Lime are consulted early
in the design process.
Waterproofing and Stabilising layer - Unilit 30 waterproofing and
stabilising layer.
Apply Unilit 30 as the undercoat mortar for plastering
and rendering of internal and external walls below ground level, up
to approx. 1 meter above ground level and other areas where damp and/or
salts are present or expected.
Unilit 30 is impermeable to water but very vapour permeable and can be used as an
undercoat or as a coarse finishing coat as part of a Unilit mortar system. The mortar can be
applied to damp walls of buildings and cellars.
Where high levels of damp and salts are prevalent, e.g. basement walls the minimum total layer thickness of Unilit 30 must be 20
mm, for the minimum waterproofing performance the minimum total layer thickness
must be 12 to 15mm.
Unilit 30 and Unilit 35M are normally applied in adjacent areas to the same
thickness with a finishing coat applied over both to give a uniform finish.
Unilit 30 can also be applied as a pre treatment prior to applying Unilit 35M,
or as the first 15 - 20mm render thickness in place of Unilit 35M where greater
thickness is required.
If a finish or following layers are applied to Unilit 30 after 1 week (or where
Unilit 30 has fully dried), a bonding layer of Unilit 15/P1 or 15/ P2 is
required.
A colour finish can be applied with a lime paint - Corical
- Lime wash and lime paint finishes are available from Telling Lime.
Alternatively a through coloured finish - Unilit 65f/65M/65N or a Telling
Cori polished finish can be applied.
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
(silicones or similar) it is recommended to consult the supplier or manufacturer.
Bonding agent: Unilit 10 / Unilit 15/P2.

Waterproofing and stabilising layer (if required): Unilit 30.
(for basements and other places susceptible to
rising damp, or high levels of damp or salts). see
Unilit 30
clause.
Application: Mix Unilit 30 with clean water - 4.5 to 5.25 litres
of water to 30 kg of powder depending on the temperature and substrate. Mix manually or
mechanically for 3 to 4 minutes.
Apply directly to either a dry or damp substrate. If the substrate
is too dry, dampen down the surface prior to overcoating. Do not apply in temperatures
below 5°C or above 40°C. The mortar remains workable for 2 hours and dries in 24-48
hours. Protect from frost for 48 to 72 hours.
Maximum thickness per layer: 15-20 mm.
Minimum total thickness of layers: 12 - 15mm for minimum waterproof performance, 20
mm for maximum waterproof performance e.g. for excessively damp and salt laden
areas, basement walls and areas below ground level.
Undercoats: Premixed natural hydraulic lime mortar.
Product reference:
Unilit 35M.
Fibre reinforcement: Seek advice from Telling.
Not Required
Thickness (excluding dubbing out): 10-15 mm
maximum layer thickness. Total thickness dependant on the application - Seek
advice from Telling.
Application: Mix Unilit 35M with clean water - 4.5 to 5.25 litres of water to
30 kg of
powder depending on the temperature and substrate. Mix manually or mechanically for 3 to 4
minutes.
Apply directly to dry substrates. If the substrate is too dry, dampen down the surface
prior to overcoating. Do not apply in temperatures below 5°C or above 40°C. The mortar
remains workable for 2 hours and dries in 24-48 hours. Protect from frost for 48 to 72
hours. Do not use mortar below ground level unless applied over Unilit
30.
Final coat: Premixed natural hydraulic lime finishing
mortar.
