Mobile Soda Blast Paint Stripping and Surface Cleaning
Baking Soda Blasting in Maryland
Soda Blast contractor services are available in all Maryland counties and beyond. Labor rates usually start at $160.00 per blast hour and time charged starts with unloading and ends with loaded-up at end of blast. Minimum charges can vary depending on the scope of the project – please ask your contractor for the details. Residential, commercial, industrial, automotive and marine charges may be calculated by the square foot, linear foot or on an hourly basis. A mileage charge may be added to mobile stripping and cleaning jobs depending on distance and/or time of travel.
Outdoor baking soda blast operations require a wide-open space. Soda blasting operations are not recommended in a residential community. The mobile compressor is a diesel-powered unit and it and the nozzle are loud. Baking soda media is a soft, friable (crumbles easily) media and will blow in the breeze quite a distance. Typically, only a dusting of baking soda will remain on the ground with the rest being airborne. We must be mindful of items (homes, vegetation, cars, people, etc.) downwind and choose an outdoor area of least impact in which to blast in. Baking Soda blasting over a gravel area is generally best, but any area can be used. Staining of asphalt can occur due to baking soda’s ability to remove grease and oils. Typical baking soda usage rates are around 50 lbs. per hour. Soda blast media is water-soluble and will usually disappear after the next good rain.
Damage To Vegetation
The process of photosynthesis in plants can be disturbed by the presence of any free sodium ion, including sodium bicarbonate. Photosynthesis uses light in the presence of chlorophyll and water to convert carbon dioxide to sugars, used as nutrients for plant life. Depending on the type of plant, sodium bicarbonate can produce temporary discoloration or cause more serious damage. The most easily upset plants are flowering shrubs, such as roses, azaleas, or lilac. Trees and grass typically turn brown, and then recover in 4-6 months. Some plants are completely unaffected. The speed of any reaction with plant life can vary widely, depending on the type of plant.
To avoid damage to plants from blasting with soda blast media:
- Avoid contact between plants and blast media residue.
- Cover plants and prevent any liquid run-off from soaking the soil around plants.
- If contact is unavoidable, the client should be aware that damage to plants could occur.
To minimize damage:
- Thoroughly soak the soil and leaves the day before blasting.
- It is best to use a sprinkler for 4-6 hours to completely soak the soil, leaves, and branches before blasting.
- Continually rinse the leaves and prevent liquid run-off from soaking into the soil around the roots.
After baking soda blasting, continue to soak the leaves and soil to thoroughly flush the sodium bicarbonate away from the root structure. The amount of soaking after blasting depends on the amount of residue in contact with leaves and roots. The goal is to reduce the sodium ion concentration below 0.5 vol% on the leaf surfaces and around the roots so that any damage will be minimized
