This Registered Detail relates to Kilwaughter Minerals Limited’s K Lime Natural Hydraulic Lime Mortar range; K Lime

Finishing 112, K Lime Setting 213 and K Lime Coarse 413 range of dry bagged mortars using lime, rather than cement as a

binder and conforming to BS998 : 2003 parts 1 and 2, for use in stonemasonry, pointing, brick laying, block laying and a

plaster and render. They designed for use with standard density concrete blockwork, brickwork or natural stone. Finishing

112 and Setting 213 can be used as bedding for natural stone tiles. Coarse 413 can be used a hydraulic lime floor screed.

The K Lime Natural Hydraulic Lime Mortar range is declared to be suitable for external use due to the results of its adhesion

and capillary water absorption properties.

K Lime Natural Hydraulic Lime Mortar range is not suitable for application on horizontal or sloping surfaces. It should not

be continued over movement joints, damp proof courses, weep holes or air vents. Adequate flashings should be provided to

prevent water penetrating behind the render.

K Lime Natural Hydraulic Lime Mortar range is suitable for use in passive conditions of exposure. According to BS EN

13914-1:2016 renders which have a Capillary Water absorption Class W0 are suitable for use in passive conditions of

exposure. Kilwaughter always recommends the use of a breathable paint as additional protection.

K Lime Natural Hydraulic Lime Mortar range have a stated (EN 13501 – 1 : 2007) reaction to fire (class) A1 are classified as

non-combustible and are suitable for all situations.

K Lime Natural Hydraulic Lime Mortar range has a shelf life of approximately 1 year if stored in original unopened

packaging in dry conditions.

K Lime Natural Hydraulic Lime Mortar range should be installed by a competent operative in accordance with the

manufacturer’s instructions and specifications and the relevant sections of BS EN 13914 – 1 : 2016 over a suitably prepared

substrate. Prior to application the prepared surface needs to be assessed for suitability, clean, smooth and free from

efflorescence. Consideration should be given to installing wall mounted fittings such as down pipe brackets prior to

rendering using stainless steel fixings. Application should only take place when the temperature of the substrate and

surrounding air exceeds 5℃. It should not be applied to damp or frozen substrates or in strong sunshine or wind, at

temperatures in excess of 35℃ or if exposure to frost is likely to occur during curing. Surfaces should to be completed

without interruption. Fresh render needs to be protected from rain, mist and frost and from drying too quickly. Drying times

may be prolonged by low temperatures and/or elevated humidity.

 

  

The K Lime Natural Hydraulic Lime Mortar range are supplied as a powder and need to be thoroughly mixed (for at least 10

minutes in order to dissolve the powder additives) with 4 – 5 litres of clean water per 25 kg for hand application by hawk

and trowel.

For render only applications the BBA certificates use the phrase “designed to be installed by a competent, skilled renderer or

a contractor, experienced with this type of product”. K Rend products are sold through various retail outlets consequently it

is not possible to control who purchases and uses the products. Kilwaughter therefore expect the end customer (i.e. builder,

owner etc.) to satisfy themselves about the quality of the workmanship expected from the installer.
