OVERVIEW
The Problem:
Associated problems caused by damp and flooding are commonplace throughout the UK’s housing stock. Growth of black mould and efflorescence caused by salt transfer can lead to the
delamination of the plaster and there is no simple resolution. Often the only choice left to the housing association or local authority is to remove the original plaster and treat the walls with a Damp Proof Course (DPC), before waiting for it to dry to receive a backing plaster – all at the expense of the landlord or local authority.
The Solution:
A Modern, Lightweight Renovating Plaster:
Limelite Renovating Plaster solves all of these problems.
Firstly, it can be applied to damp walls, saving an enormous amount of money for time that would be otherwise spent waiting for the walls to dry out – it effectively controls dampness passing through walls, as well as providing a barrier against salt transfer – ultimately allowing the substrate to dry naturally.
Secondly, and crucially, Limelite Renovating Plaster will withstand damp issues caused by future events, which may be likely in properties susceptible to damp and flooding.
Thirdly the Limelite plaster system offers Thermal Insulation by drying the walls rapidly, reducing loss of heat and insulating the internal walls to meet modern day standards
Thermal Conductivity, λ10,dry,mat, P=50% = 0.17W/m.K
Thermal Conductivity (k) at 0% moisture = 0.13W/m.K
Another benefit with Limelite plasters for internal use is their fire resistance/protection as a non-combustible product (as defined by BS476:Part 4) which can be assigned Class O in accordance with the requirements of the National Building Regulations and Reaction to Fire = Euroclass A1
Making the Difference for Local Authorities Dudley Council in the West Midlands is among the many local authorities that specify the use of Limelite Renovating Plaster when tackling such issues in social housing.
“Where a renovating plaster is required we use the original and proven, Limelite” said Andy Pratt, Specification and Design Manager for Dudley Council, which has been specified by the council for over 40 years.
Where existing plaster is sound, a small area of plaster is removed and replaced with Limelite.
In more severe cases where the existing plaster is unsound, all plaster is removed and the wall is treated with a DPC before Limelite Renovating Plaster is applied. Limelite Renovating Plaster is also used for patch repairs in areas such as window reveals, where again the damaged plaster is removed and replaced with Limelite.
