Lithomex stone repair

Lithomex

Stone repair and restoration mortar

Specially formulated mortar based on Natural Hydraulic Lime and aggregates for the repair or simulation of masonry, brick or stone. Lithomex is a custom coloured mortar supplied in 25KG bags and 4kg tubs to which only mixing water is added.

Lithomex has high vapour permeability, low modulus of elasticity, excellent bond characteristics and achieves early freeze thaw resistance. Lithomex develops early strength but not such that it becomes stronger than the background. It is not suitable for repairs to stair treads.

Applied at minimum thickness of 5mm (can be dressed or cut back to a feather edge). The maximum recommended unsupported thickness is 80 - 100mm. (Not projecting work) In cases where a thickness greater than 100mm is required some anchorages may be required. In the case of full depth projecting work anchorage is advised.
Simulation of stone / brick features, rough finishes, false joints etc. can be made approximately 5 hours from application (in damp cold weather leave up to 24 hours).

Shaping and forming of details, corners and such can be carried out with the edge of a trowel or steel float and carved details with small tools as the work proceeds or using chisels once the material is fully hardened. Fine polished finishes are achieved either by troweling after initial set has begun or by fine carborundum paper after the material is sufficiently hard. Its unique qualities allow it to be tooled, shaped and sculpted even weeks after the final set has taken place. This affords sufficient time to achieve the very highest standard of work with the best quality reproduction. Where ashlar masonry or very finely jointed masonry has suffered damage to the arises, flush finishing in Lithomex with a tucked joint is the ideal solution. Lithomex can be lime washed.
