Pulverised Fuel Ash or PFA (BS EN 450 - N) is manufactured as a by-product of coal fired power stations. It is a high-quality, low sulphur, low embodied CO 2
material.
PFA is a fine light grey powder that can be added as a mild pozzolanic addition and colourant to lime mortars, plasters and renders.
NB. Every effort has been made to ensure the accuracy of the colour and texture of products on this website but due to the limitations of technology, we strongly recommend that sample products are purchased for testing in situ prior to the full order being placed.
NB. It is strongly recommended to use a competent builder/plasterer who is experienced in using lime products with the requisite skills, technique and specialist qualifications and experience to carry out the job.
NB. Pozzolanic PFA products are sourced from naturally occurring raw materials and on occasion may differ slightly from batch to batch in colour and texture. Every effort is made to produce a consistent product as part of the manufacturers own factory controlled procedures and quality control in line with EN Standards. It is strongly recommended to test a small amount of material, in situ, to assess suitability and performance and purchase adequate amounts of product from the same batch to fulfil any job. Chalk Down Lime Ltd can NOT guarantee the colour and texture of any pozzolanic PFA products.
