Stone Repairs

Our Stone Repairs Edinburgh Service Is The Repair Of Decayed Or Damaged Stone…

It is the act of restoring the masonry piece back to its original profile and re-instating its surface finish, texture and colour.

This is a different process from the replacing of a decayed stone, whereby a whole stone is cut out, discarded, and replaced with a new stone.

The stone is then sized, dressed and fitted as per the original stone.

This process is called indenting. We often have to do this if the stone piece in question is too badly eroded to save or if the listing on a building prevents surface stone repair.

The First Stone Restoration Edinburgh Step:

Our stone restoration Edinburgh services chisel back the existing stone until all the decayed and loose material has been removed. We then wet the stone to be repaired to slow down the setting of the mortar once applied to the repair.

This improves its binding to the host masonry, and stops cracking. If the repair is deep, we insert stainless steel screws into the masonry to give improved grip to the stone.

The Second Stone Restoration Edinburgh Step:

The next stage is to apply coats of a lime based repair mortar we use called Lithomex. Often referred to as Lithomix (depending on the depth of the repair) we may have to apply several coats of Lithomex to complete the repair.

We can only apply around 8mm at a time and allow to dry out if we are to attain optimum results. The final coat of Lithomex is left 1-2mm proud of the finished surface and left to harden – at least overnight.

The Third Stone Restoration Edinburgh Step:

Next, we rub down the repair to its final shape and profile. This is done by using abrasive pads, blocks, knives, and straight-edges. Depending on the stone being replicated, this is the most skilled part of the operation and can often be time consuming.

Any surface finishes, such as droving, stugging or broaching are applied at this stage.

The Final Stone Restoration Edinburgh Step:

Finally we “age” the repair (if appropriate) to match with its local surroundings a wee bit better. This procedure can sometimes make the stone repair almost disappear, which is the desired result.

Tell Me A Bit About Lithomex…

Lithomex is a lime based stone repair mortar marketed by Masons Mortar in Leith, Edinburgh. For long lasting and convincing results you simply cannot beat Lithomex stone repairs.

Lithomex is carefully formulated to be stone-like once it has set. Firstly, any sandstone in Edinburgh can be exactly colour matched using this product.

Lithomex Behaviour:

More important than the aesthetic qualities of Lithomex is the way it behaves when applied to stone. First, it is manufactured to be porous to water so when the repaired stone gets wet (with driven rain for example) water can escape through the repair just as it would if there was no repair.

Why Is This Important?

If the repair were waterproof, like a cement repair is for example, water can build up behind it, unable to escape. When this happens in winter the trapped water can freeze, which causes it to expand, which then pops the repair off. Not good.

Moves in Harmony:

Another great feature of Lithomex is the way it moves in harmony with the repaired stone. When stone gets warm, cold or wet, it contracts or expands.

This happens often. Lithomex is designed so it contracts and expands at the same rate as the natural sandstone ensuring they don’t part company.

Samples Available:

When we first visit you, we bring a box of Lithomex samples to allow you to choose an exact colour match for your building. This is a huge jump forward from the ugly and destructive grey cement-based stone repairs we see all over the city.
