Lime Rendering in Manchester

Lime Rendering Contractors working on Grade II Listed Building in Salford, Manchester

On this project in Salford, Manchester we were asked by a private client to Lime render the external panels of this Grade II Listed Building. The panels had been installed by the Restoration Contractors who repaired the Oak Frame. The panels had been made up of sheep's wool insulation & woodwool boards internal and external.

Our specially skilled Lime Rendering Builders applied 3 coats of Lime Render made up from a Hydraulic Lime NHL 3.5 on site with local sands.

Lime Rendering Oak Frame Panels

Lime Rendering is a specialist job that should be undertaken by experienced craftsmen. Our Restoration Craftsmen have been using Lime Plasters & Lime Renders for many years. This project involved the use of a Hydraulic Lime based lime render which we prepared on site. As a company we try to avoid the use of premixed lime renders as they can contain materials such as cement. We sources local sand that could be used to give us the correct mix needed to make a good Lime Render. We stock a large range of limes in our working based in Burnley, Lancashire.

Lime Rendering Listed Building Manchester

For this project we decided to use a Hydraulic NHL 3.5 lime binder as this has good setting strength & will weather well. The client had advised us that they did not want to use a premixed lime render such as Thermocromex, Monocromex.

When using a Lime Render on a Grade II Listed Oak Frame Building the contractors have to be extremely careful not to let the Lime Render have to much contact with Oak as this can lead to discoloration. The Oak Frame will turn black if the Lime has contact with the Oak for any long periods, it is always good practice to have a bucket with clean water and a sponge so any Lime render can be removed for the Oak Frame.

We started from the edge of the panel, point the gap between the woodwool boards and oak frame. For this Lime Pointing process we used a caulking mix, this allows expansion and contraction of the oak frame building without cracking the Lime Render.

You will see on the woodwool panels in the Oak Frame that they are installed using stainless steel screws and washers. This oak frame has not been cleaned in any way using DOFF or any other system.

This had been formed with sawn larch laths as the woodwool boards could not be bent to form the curve. As the lime render on the lath needs longer to go off we decided to Lime Render this first. This had been scratched using a scratch comb to allow a good key between the base coat lime render and the float coat lime render.

This mesh helps the lime render from cracking where the joints are in the woodwool boards. If the mesh was not install cracking could occur in the panels on the Timber Frame Building.

When applying lime render it is important not to allow the lime render to dry out to quickly. If the lime render does dry out to quickly it can cause it to crack and de bond.

The open texture of the board enables to the lime render to adhere well. Even tho the woodwool boards contain a small amount of cement the open texture allows moisture to pass through the board making them breathable.
