Definitions:
RECOVER (old stones found to augment the broken/eroded ones, in the original style)
REPLACE (new stones bought, the original stonework is replaced, in the original style)
RE-FORM (make-do stones: the damage is excised, new or old stones are attached)
RESTORE (good-as-new: damage is excised, new stonework is attached or replaced)
RESTONE (better-than-new stones are chemically created in-place, in the original style)
Better-than-new stones:
A stone (/stōn/) is simply 'concreted earthy or mineral matter; rock', concreting is the process of chemically annealing. Our process begins by identifying the substrate (the mineral/material) that was originally quarried/produced for your damaged or missing stonework then finding a recipe for regenerating a composite. This is not identical to the one being replaced, but near enough to perfectly anneal to it and behave similarly. Additionally, and arguably more importantly, our composites can ingress into the existing (unexcised) stone, beyond the boundary of the repair, affecting chemical change to preexisting stonework. The aim of this to to retard the processes that have led to the stonework failing to the point where it needed replacing or repairing but to also arrest the continuing degradation of the original stonework beyond that point. As a result, the repair doesn't merely renovate the stonework, but should prevent the damage spreading further into the stonework.
Another definition: REPAINT
The solution we offer cannot alone replace a beautifully modern satin or classic gloss finished exterior. It's almost certain that your masonry will need repainting to recapture that as-new finish. It's also likely that insufficient or ineffective painting of your exterior stonework is the thing that allowed the degradation to set in the first instance. We repaint all of our work, regardless of any difficulties we may face in doong so (e.g. access), with at least two coats of 15-20 year lifespan, advanced, Dutch made, imported paints. These paints are based on a liquid crystal which, when applied appropriately, will ingress into the substrate and seal, prime and protect for a long-lived and beautiful top coat.
