Shou Sugi Ban Timber Cladding, does the charred surface rub off?
On exterior Shou Sugi Ban the charcoal layer will rub off on your hands or clothes when you touch it, this is the loose particles on the surface of the timber.
As the Shou Sugi Ban is exposed weather the loose particles that causes this issue will wash off the timber from the wind and rain over a few months and the rubbing off will stop.
So, what about Shou Sugi Ban not exposed to weather?
If your looking for Shou Sugi Ban timber cladding for interiors or areas not exposed to weather, Mortlock Timber use a different timber coating on the surface which binds the char layer together and eliminates the rubbing off.
You do need to be aware that the charcoal layer is not as hard as timber, if its knocked hard enough it can break the coating on the surface and it will cause minimal rubbing off. This can be easily touched up with the same coating
So, what about other companies claiming that the charcoal on their Shou Sugi Ban product does not rub off, even in exterior applications?
They are either using a different coating, or the char layer is not thick enough.
In that case what coating product does Mortlock use?
