Soda Blasting 450 Square Feet of Timber in a Weston Great Room
1 / 4The timber before work. Old structural wood like this is why soda blasting gets specified: it lifts what is on the surface without cutting into the surface itself.
What Happened
Soda blasting is abrasive cleaning using sodium bicarbonate as the media. It lifts material off a surface without cutting into the surface itself, which is why it gets specified on old structural timber, masonry and equipment where sanding would remove the material along with the problem. On this Weston project 450 square feet of timber was blasted in a great room with exposed beams and posts. If you only read that one line, this looks like a modest job.
The rest of the estimate is what makes it a real one. 1,500 square feet of the room was covered in plastic and 500 square feet of floor protected before any media was fired. Four 24 hour negative air periods ran across the work. Afterwards, 1,500 square feet was HEPA vacuumed in detail. That is more than three times the blasted area, in every direction, and it is not padding. Blasting propels media and everything it removes off the surface at speed. It does not fall neatly at the base of the beam.
It travels, it settles on every horizontal surface in the room, and in a space with a cathedral ceiling and glazed doors it settles on all of them. The containment and the cleanup are the job. The blasting is the quick part. Three pieces of equipment were decontaminated per piece on completion, which matters on a blasting job because the gear itself is coated by the end of it. What was not sold here is worth being precise about, because blasting is often bundled with finishing work. No sealing, no coating, no antimicrobial and no refinishing of the timber was quoted or performed. No testing or clearance was carried out.
The timber was cleaned and the room was cleaned, and that is the whole of it. Anyone quoting soda blasting alongside a finish coat should be showing both as separate lines.
Scope of Damage
Structural Timber
Moderate450 square feet of exposed timber blasted with sodium bicarbonate media, which lifts material off the surface without cutting into the wood the way sanding would.
The Room Around It
Moderate1,500 square feet covered in plastic and 500 square feet of floor protected before any blasting started, because media and removed material travel across the whole space.
Post Blast Settlement
Moderate1,500 square feet HEPA vacuumed in detail afterwards, more than three times the blasted area, because everything the blast lifts settles on every horizontal surface in the room.
How We Solved It
- 1
Cover Everything First
1,500 square feet of the room covered in plastic and 500 square feet of floor protection installed before any media was fired. On a blasting job the protection is not a precaution, it is the method.
- 2
Four Negative Air Periods
Negative air scrubbers ran across four 24 hour periods so airborne media and removed material exhausted through a filter rather than settling into the rest of the house.
- 3
Blast 450 Square Feet
Sodium bicarbonate media applied to the exposed timber. Soda blasting cleans without cutting into the substrate, which is why it suits old structural wood where sanding would take the surface with it.
- 4
HEPA Vacuum 1,500 Square Feet
Detailed vacuuming across more than three times the blasted area, because blast media does not fall at the base of the beam. It settles on every horizontal surface in the room.
- 5
Decontaminate The Equipment
Three pieces of equipment decontaminated per piece on completion. On a blasting job the gear is coated by the end of it.
Tools & Equipment Used
Questions Homeowners Ask
What is soda blasting and when is it used?
Soda blasting is abrasive cleaning using sodium bicarbonate media. It lifts material off a surface without cutting into the surface itself, which is why it is specified on old structural timber, masonry and equipment where sanding would remove the substrate along with the problem. This Weston project blasted 450 square feet of exposed timber.
Why is the containment area so much larger than the blasted area?
Because blasting propels media and everything it removes off the surface at speed, and it does not fall at the base of the beam. On this project 450 square feet was blasted while 1,500 square feet of the room was covered and 1,500 square feet was HEPA vacuumed afterwards. The containment and cleanup are the bulk of the work.
Does soda blasting damage old timber?
That is the reason it gets chosen. Sodium bicarbonate is softer than the media used in sandblasting, so it removes surface material without cutting into the wood underneath. On structural timber where the surface character matters, that difference is the whole point of specifying it.
Is the timber sealed or refinished afterwards?
Not on this project. No sealing, coating, antimicrobial or refinishing was quoted or performed, so the timber was handed back cleaned and bare. Finishing work is a separate scope. If a quote bundles blasting and a finish coat into one figure, ask for them as two lines.
How long does a soda blasting job take?
It scales with the containment and cleanup rather than the blasting. This project ran four 24 hour negative air periods across the work. Ask how many negative air periods are in your quote, because that is a fairer indication of duration than the blasted square footage alone.
