When looking to get bricks professionally cleaned you should consider getting a firm that know what they are doing. Furthermore, it may be a good idea to introduce your brick cleaning firm to your bricklayer before work begins as this can help with the process.
There are a number of methods used to clean bricks:-
Brush cleaning with chemicals
This is chemical-based cleaning and is the most popular method that is used when cleaning bricks. Professional brick cleaning firms will be able to tell who your bricks were made by and subsequently will be able to recommend the correct chemical cleaner for the job and the amount of time that the chemicals should be left on the bricks. This process involves brushing chemicals onto bricks and then scrubbing the chemical back off. The chemical should also be rinsed to avoid patches.
Pressurised water cleaning
Water pressure is a good method to use when time is of the essence as this method saves time and labour. This method takes a lot more skill to execute and if not done correctly can result in damage to the bricks. A good firm will know exactly how much water pressure to apply to the bricks and what preparations are required to avoid damaging the bricks.
Sandblasting
Sandblasting is another method used to clean bricks and doesn’t run the risk of chemical reactions or water stains to the bricks. If sanding blasting isn’t done correctly it can leave bricks scarred, however. Not all types of bricks can be sandblasted - this includes sanded, glazed and coated bricks.
