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 Natural Hydraulic Lime Finishing Mortars.
Unilit 30 - Coarse weatherproof finishing mortar for external render.

Unilit 30. Finish - Coarse weatherproof finishing layer. (see Unilit 30 clause for undercoat application)
A dry, premixed mineral stabilising mortar based on hydraulic, naturally pure and selected lime. Designed particularly for situations where rising damp or capillary action is prevalent, the mortar is characterised by a high plasticity, slow but strong bonding and a low salt content. 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 undercoat layer thickness of Unilit 30 must be 20 mm, for the minimum waterproofing performance the minimum total undercoat layer thickness must be 12 to 15mm.
Where applied as a finishing coat Unilit 30 is applied by steel trowel a minimum 4 - 6mm thickness and can be sponged or wood floated to the desired coarse, open textured, water repellent finish.
A colour finish can then be applied with a lime paint - Corical - Lime wash and lime paint finishes are available from Telling Lime Products and can be applied within 2 or 3 days after the application of Unilit 30.

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.

Product reference: Unilit 30.
Thickness: 4 - 6mm overall.
Finish: Seek advice from Telling. Sponged or floated to the desired finish.
Application: Mix the mortar 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 5 minutes.
Apply manually or mechanically to a dry or damp substrate in a 4 - 6mm thick layer by trowel. 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.
