Depending on the extent of damage or decay to the stone, a repair can be the perfect alternative to carrying out a stone replacement. Using the lime based material lithomex, we can apply this over the affected stone giving it the appearance and structure of a brand new stone.
Before applying lithomex it’s important to chisel away all the loose and decaying stonework back to a solid surface.
This creates the perfect base for the lithomex to bond to.
Once applied and partially set, (which usually takes around 24 hours ) we rub back and shape the lithomex to recreate the original surface.
At this stage we can also dress on any surface finish to match the surrounding stonework.
If a solid surface is not found within the ideal depth due to internal decay, a repair won’t be suitable and we will advise replacing the stone.
We may also recommend a replacement or descaling of the stone due to it’s location on the building.
For example, repairing areas directly above doorways and paths should be avoided. Although a well executed repair can last upwards of 10 plus years, they are temporary and will eventually fail and detach from the original stone.
In this example, the original stone would of been dressed on a comfortable waist high table. Here’s Paul dressing the repair in situ creating a “stugged” surface finish to match the surrounding stonework.
At this stage we can also cut false joints that will be pointed in lime mortar to create the illusion of a built in stone.
