What is Sandblasting and how to sandblast?
Sandblasting is a high-efficiency abrasive blasting technique that propels media such as silica sand, crushed glass, garnet, or recycled steel shot under compressed air to strip paint, remove rust, and clean masonry surfaces, making it ideal for brick restoration, facade cleaning, and graffiti removal; trained technicians employ PPE, dust suppression systems, and containment enclosures to protect stone, mortar, and historic substrates while performing precise surface preparation for repointing, limewash removal, anti-graffiti coating application, and structural cleaning on chimneys, Victorian terraces, commercial cladding, and industrial steelwork, balancing abrasive type, nozzle size, pressure settings, and standoff distance to avoid surface etching, minimize substrate loss, and achieve uniform finish for repainting, sealing, waterproofing, or heritage conservation projects.
Why Sandblasting?
ACRA Exterior Cleaning Services recommends sandblasting when traditional methods fall short because it delivers fast, thorough paint removal and deep brick cleaning that restores masonry to its original condition; in London, our brick restoration and brick pointing teams use controlled sandblasting techniques to remove stubborn coatings, graffiti, and cement residues without compromising structural integrity, ensuring long-lasting results for commercial and residential properties while meeting the highest standards for safety and conservation.
What is the Best sandblasting equipment for bricks?
When restoring brickwork, the best sandblasting equipment combines precision, adjustable pressure settings, abrasive versatility, and dust suppression — features exemplified by IBIX, TORC systems, which offer low-pressure, rotary and suction-driven solutions ideal for delicate masonry. At ACRA Exterior Cleaning Services we use the best equipment on the market, including IBIX and TORC machines, professional sandblasting cabinets, dry blasting and wet blasting units, micro-abrasion tools, and HEPA-rated dust extraction systems to ensure safe, efficient brick cleaning, paint removal, limewash stripping, and masonry restoration. Our brick restoration and brick cleaning services rely on specialist sandblasting tools for sensitive tasks like pointing repair, mortar joint preparation, efflorescence removal, graffiti removal, and historic conservation, delivering consistent results while protecting surrounding stone, terracotta, and heritage surfaces.
Types of abrasive media for sandblasting
Abrasive media for sandblasting vary widely to suit different surfaces and cleaning goals: traditional silica sand (now largely restricted due to health risks) provides aggressive cutting action for heavy-duty removal; crushed glass is a common substitute offering fast cleaning with reduced crystalline silica exposure; garnet is a durable, angular mineral ideal for metal and masonry where a coarser profile is acceptable; aluminum oxide is a hard, reusable grit used for precision surface preparation and paint removal; steel grit and shot offer high-impact cleaning and peening for robust steelwork; plastic abrasives and walnut shells provide gentler, non-sparking options for delicate substrates and restoration work such as soft brick or historic facades; and specialty media like sodium bicarbonate (baking soda) and dry ice deliver low-abrasion, residue-free cleaning for sensitive surfaces and situations where minimal surface profile or chemical contamination is required.
Best media for brickwork
Choosing the best media for sandblasting brickwork depends on the brick type, age, mortar condition, and the finish you want to achieve; at ACRA Exterior Cleaning Services we select the optimal abrasive—such as crushed glass for gentle yet effective paint removal and limewash stripping, fine garnet for controlled cleaning of historic or soft-fired brick, non-metallic walnut shell or dry ice for delicate restoration where minimal surface abrasion is required, and high-quality silica-free aluminum oxide or copper slag for more robust restoration tasks—always balancing removal power with preservation to avoid damage to brick, pointing, and mortar joints; we use industry-approved, blast-cleaning media tailored to each surface to provide safe, efficient brick cleaning, brick restoration, paint removal, and brick pointing preparation at the highest standards.
