Washing brick stone siding with acids as well as various other liquid cleaning products might not be the ideal cleaning approach to utilize, considering that acids could soften the building material. The best option would be to sandblast the brick stone siding. The sandblasting process may look overwhelming and require professional help, but basically, the process requires a sandblaster to propel sand or other types of grits to help clean the surfaces and remove paint. There are health concerns regarding the use of acids in cleaning and sandblasting, but the latter can be prevented by wearing the proper working gear.
Prior to beginning the sandblasting job, cover the windows with used wood boards or plyboard. Cover various other locations that are not brick with tarpaulins or heavy duty adhesive tape. See to it that the only areas revealed are the brick stone siding surface areas.
Determine what particular type of grit or material to use to complete the sandblasting process. Sand particles have different grades so it’s best to ask for recommendation from the supply store. When you’re opting for simple cleaning solutions, you should go for super fine articles. Rougher grains must be used on hefty cleaning. When cleaning just recently mortared brick wall surface, eliminate huge parts of mortar with hand devices and allow the mortar to completely dry for 2 weeks at the very least prior to sandblasting.
Safety and Security Procedures
Cautious security procedures are needed prior to the actual sandblasting job. Take note that high velocity of sand particles could be harmful to the skin, the eyes, and also other parts of the body.

Check the sandblaster at a close distance and see if it has cleaned the tiny surface area. Try to move a bit farther from the tested area until you reach the the right distance.
Tidy the Entire Area
Stand at the optimal range and also sandblast the whole area of the wall surface ,and also move from location to another after each section of the wall has actually been cleaned up. Never ever take too long at one section of the wall surface as the sandblaster could do even more damages.

Never attempt sandblasting a brick stone siding with mortar that has not yet entirely cured. Always wait for weeks before proceeding.
