Jeff, it certainly is time consuming. The pressure cleaning is two fold. It removes the dust and slurry from the saw but it will also remove any excess mortar on the face of the stone. If the mortar is a bit wet it will stain the face of the stone and this spoils the look of the wall. Thats why its better to lay the stone before it is pressure cleaned....the dust actually makes it easier to clean off.

We prefer sacraficial sealing and anti-graffiti systems. With natural limestone (and always holding some moisture) a breathable sealer is important, hence the acylic coating which really just hardens the surface of the stone. The Anti-Graffiti system is basically Acrylic with Wax. If the wall is Tagged you wash it off with a Hot water pressure cleaner.....the Tag and the wax coating disappear. Then you just allow it to dry and apply another wax coating. The coating is totally transparent and doesn't change the colour of the wall or make it look shiny like some systems do.

Our 16" Husky cuts that stone in a flash. Its generally very good to work but it frequently has "Capstone" which is essentially a section of fossil in the stone. This is well harder than granite and will bring sparks from the blade...or chip your cheap adze.
