When faced with a large expanse of brickwork to clean and restore, you need a reliable partner with the techniques and equipment to do the job properly, without causing damage. Conventional blast cleaning or using a chemical brick cleaner has the potential to damage the delicate surface of old bricks. APT soda blasting is a far better solution …
Sympathetic Brick Cleaning
Soda blasting is accepted by conservation architects as being the best possible way of cleaning and restoring old brickwork. It is a powerful cleaning technique that removes only the grime and not the surface underneath.
Soda blasting doesn’t work by abrading the surface, which is why it is such an excellent brick cleaner.
The process of soda blasting fires crystals of bicarbonate of soda (blasting soda) at the surface to be cleaned using compressed air. On contact, the crystals shatter. The energy released from this shattering of crystals disrupts the surface cohesion of the contamination which is simply blown off the surface of the bricks.
Because blasting soda has a similar hardness to talcum powder, when the soiling has been removed, it will not abrade the surface of your brickwork as your bricks are harder than the soda crystals.
Cleaning your bricks is an important stage of any restoration project and preservation is of paramount importance. Blast cleaning with abrasive materials is not an option as the surface of the bricks will be degraded. Neither is using a chemical brick cleaner, this too can damage the brickwork and the mortar joints; this unwanted extra damage to the bricks will increase costs and set back the completion date.
APT use soda blasting, keeping costs to a minimum without compromising the quality of your brick restoration project. Using soda blasting means that cost-effective restoration, repair and replacement can be carried out on all types of brickwork from plain faced brick walls to delicate and complex decorative moulded bricks.
In some cases, where minimal restoration is required, expert masons will replace damaged bricks in-situ and repair rotten and weakened mortar joints. In cases where the restoration needs are more extensive, your brickwork will be dismantled by our experts, carefully numbered and stacked in sequence. Rebuilding will be carried out with the same care and precision as the dismantling, using appropriate mortar and mortar styles.
We will carefully select handmade new bricks or reclaimed bricks that match your existing bricks. Where these are not available, we will draw up an exact specification from which your replacement bricks will be made.
Many historic houses and listed buildings have expanses of interior brickwork that require cleaning – stable blocks, workshops, walls prior to traditional lime plastering and so on. Leaving bricks in a natural clean state is also popular in other renovation projects but to make them look really good, they need to be impeccably cleaned. Soda blasting enables you to do this quickly and efficiently, without the need for expensive, harmful and aggressive chemicals.
