Get Wood Sandblasting QuotesWhere It Can Work
- Exposed roof beams and trusses with old paint or soot.
- Weathered decking frames, pergolas and outdoor furniture.
- Rustic or textured finishes on hardwood beams and doors.
- Fire-damaged timber that is structurally sound.
Risks to Timber
- Raised grain. Blasting wears away soft growth rings faster than hard ones, leaving a ridged texture. Some people want this look, many do not.
- Soft timber. Pine and other softwoods erode quickly and can be gouged.
- Detail. Carvings, mouldings and sharp edges can be rounded off.
- Veneer and plywood. Thin layers can be blasted through.
- Lead paint. Old paint may contain lead and needs controlled removal.
The Test Patch
Ask for a test on a hidden area with the proposed media and pressure. It shows how the timber responds, how much grain is raised, and whether the finish is what you want before the full job is priced and done.
What the Process Involves
- Test patch and agreement on the finish.
- Protect walls, floors, windows and fittings, or move furniture to a workshop.
- Blast with a softer media such as crushed glass, walnut shell or soda, at low pressure.
- Clean dust from joints and the room.
- Light sanding and sealing, oiling or varnishing.

Ballpark figures, not quotations. Compiled from price guides and price lists published on South African websites (published between April 2025 and December 2025), checked 13 October 2026 and rounded. Most are national or Gauteng guides, so Cape Town quotes can differ. Unless a row says so, the sources do not state whether VAT is included, so confirm VAT on every quote. Photos, an inspection and a written quote set the actual price.

Frequently Asked Questions
Can all wood be sandblasted?
No. Softwoods, veneers, plywood and detailed carvings are easily damaged. A test patch shows whether the timber is suitable.
Will sandblasting raise the grain?
Usually, to some degree. It wears softer wood between the growth rings. Lower pressure and softer media reduce it.
Can ceiling beams be sandblasted indoors?
Yes, but the whole room must be sealed and protected, and clean-up is significant. Some contractors prefer softer media or other stripping methods indoors.
Is wood sandblasting better than sanding?
It is faster on rough, textured or awkward surfaces. Sanding gives more control on flat, finished surfaces such as furniture tops.
What finish goes on after blasting?
Usually a light sanding, then oil, sealer or varnish to protect the exposed timber.
