Household mold is a nuisance that is both expensive and tricky to completely get rid of – you can’t leave it growing in the house either after discovery, since it can pose a serious hazard to the health of the home’s inhabitants. Recent years have seen a boom in the mold removal industry, with companies competing with each other in bringing the most cost effective, efficient removal technology to the clientele. Abrasive blasting is one such technique which is becoming increasingly popular, owing to its effectiveness and reliability.
Conventional processes for getting rid of mold are notorious for being time consuming and hard, requiring large amounts of manual sanding and scrubbing. A new technique known as abrasive blasting is gaining traction and might soon replace the older methods since it is faster, easier and much more effective in taking care of mold infestations. This process involves finishing/cleaning objects using a centrifugal wheel or a blast of air to pelt abrasive particles on their surface at a high velocity. Corncobs, sand and dry ice are all possible candidates to be used as these tiny particles. Mold remediation, in particular, employs baking soda, as well as dry ice, for abrasive blasting.
Advantages of abrasive blasting
Also known as ‘media’ blasting, this technique has some unique advantages over conventional mold removal methods. Besides doing away with most of the tiring manual work required in scrubbing / sanding, this newer technique shows its usefulness in dealing with mold growing on hard to access / irregular surfaces. For instance, surfaces which have bridging or cross bracing can be decontaminated with greater ease. Hard to reach places like crawlspaces and attics are also easier to clean using this method in contrast to conventional techniques. You also benefit from the lesser time required to do the remediation – meaning you can be back to the house much quicker than in the case of conventional remediation.
This type of abrasive blasting uses baking soda i.e. sodium bicarbonate, blasted using pressurized air, to target mold growth on surfaces. Arguably its most famous use was in the Statue of Liberty’s restoration which took places from 1982 to 1986, under the orders of President Reagan. The sodium bicarbonate crystals used as medium in the blasting process are made in modern facilities and have the shape of microscopic knives; they are soft, yet angular. The baking soda is soluble in water and results in a neutral pH i.e. (you don’t have to worry about acidity or alkalinity on the surfaces). It is great for removing mold without damaging the surface underneath e.g. PVC, ductwork, modern wiring, wood, and so on. When applied using the correct equipment and methodology, it results in swift, efficient mold removal with little waste, clean-up and damage.
When using soda blasting, it is important to use a nozzle of the correct size, for it will minimize the quantity of baking soda required. Lesser the amount of medium used, greater the visibility you will have during the process and lesser the amount of clean-up needed after the process.
