If I have a damp proof course installed does every treated wall need to be re-plastered?
Specialist replastering is an essential part of Rising Dampness treatment.
A new damp proof course will prevent moisture rising into the walls, however rising dampness brings soluble salts into the brickwork and wall plaster, which are hygroscopic. The effect of the hygroscopic salts prevents the existing wall plaster from drying out effectively and therefore replacement with a salt retardant render, such as Kenwood Waterproof Rendering System is essential in order to provide a dry internal finish.
Kenwood Premix Waterproof Rendering System is factory produced and consists of specially blended dried sands, cement, lime, aggregates and high performance waterproofing additives, along with polypropylene fibres to reduce shrinkage. These are weighed and mixed under a computer controlled system with rigorous quality control procedures.
Kenwood’s waterproof rendering system, ensures perfectly batched renders every time, purpose designed to complement Kenwood Plc’s range of damp proofing systems.
Most other renders in general use are hand mixed by operatives on-site and are measured by volume rather than weight. Kenwood’s Premix Waterproof Rendering System is a key feature in ensuring reliability of a damp proofing system. Our rendering system is specifically designed for use on damp walls and removes the risk of unsuitable, poorly batched renders, which are commonly responsible for the failure of otherwise effective damp treatment. Kenwood’s waterproof rendering system is applied by our own operatives ensuring complete quality control at all stages.
We provide a fixed price for our waterproof rendering and plastering works, which, quite uniquely to Kenwood Plc, ensures that once the plaster is removed, irrespective of the plaster thickness, the price remains the same. We do not make an additional charge when the plaster is found to be thicker than expected.
When comparing quotations, it is important to note that most companies provide an estimated cost for this work, normally made on the assumption that the plaster does not exceed a certain thickness (often 18-25mm) and they will make an additional charge, if once the plaster has been taken off the wall, it is found to exceed this thickness.
You can be assured that with Kenwood Plc, the price we quote for the rendering and plastering, is the price you will pay and we do not request any additional charges if thicker plaster is encountered. You can be confident therefore that the quoted price for the works specified remains fixed.
