FibreChalk is the result of many years of research and development by Anglia Lime Company (ALC). Twenty years ago they carried out tests that revealed the ancient lost recipe for ‘Haired Chalk’ lime plaster. This plaster had been used for centuries all over the country and is still regularly found in perfect condition. ALC subsequently reintroduced the mix and have been supplying it ever since.

FibreChalk is the innovative modern version of this ancient Haired Chalk plaster. With just the replacement of the animal hair with synthetic fibres it replicates not just the look of this old plaster but also its extreme flexibility and breathability:


With its incredible flexibility it accommodates natural movement in a building structure, resists shrinkage, cracking and shearing.


FibreChalk is vapour permeable so will help to prevent the build-up of moisture levels in your building.

Eco Friendly

The lime in the plaster absorbs nearly its own weight in CO2 during the curing (drying) process. In addition, the manufacturing of lime uses 20% less CO2 than cement manufacture.

FibreChalk is the natural choice of plaster for traditional lath and plasterwork and timber framed buildings indeed it is universal in its application for Historic and Listed Buildings and conservation projects. However its key features also make it perfectly suited for use with modern and ecological building materials such as: Lightweight block, metal lath, plasterboard, clay, wood wool board, timber lath, reed, straw bale, brick etc.

FibreChalk can be applied onto practically any background in any thickness in either one or multiple coats. It is also great for pargetting and decorative work, from traditional geometric pressed-in designs to heavy relief and family crests.

FibreChalk is an easy-to-use, versatile plaster that comes ready mixed – just pick up the trowel and apply!

The last 25 years have seen the use of building limes develop from what was regarded as a quaint eccentricity to an understanding that they are a central element of building conservation. This understanding led to a realisation that the properties of lime could be utilised very effectively in new-build work.

It also became obvious that building with lime is of key relevance to current environmental concerns.

Since 1993 when Anglia Lime Company pioneered the use of lime in East Anglia through training courses and the distribution of lime materials, this new awareness has brought about an ever-increasing use of lime in both old and new buildings.

In turn, this has led to the development of lime-based products and systems that make the use of lime more efficient and convenient, while retaining the beneficial properties of lime.

Anglia Lime Company can offer a sustainable lime-based solution, whether you are repairing plaster in your 15th Century cottage, re-pointing Georgian brickwork, installing a lime concrete floor or looking for a pre-coloured, spray applied finish for the most modern of buildings.
