| Building
stone is often hard to clean because of its multiple surfaces,
and the various materials that can adhere to it. Hot water
works much better that cold water but the products used
are also VERY important.
We have several products to use on this kind of material,
apart from traditional acid. Pressure can also be used.
Be careful on older building fwith pressure over 2,000
pounds per square inch, some of the joints may be destroyed.
When
this happens we can refer you to a construction
partner that we highly recommend.
