Sand blasting internal doors?

[Possom]

I happened to read a newspaper article which states that timber doors can be sandblasted.

I've never heard of this before as a method of stripping paint from a door.

Is it more harmful to a timber door than, say, having it dipped?

depends.
it is bloody aggressive - often used to strip old paint from exposed beams.
it can put holes in steel. it will embed sand in the wood
soda blasting or dry ice blasting is gentler
dipping can open grain nd doors can swell

depends.

soda blasting or dry ice blasting is gentler

Haven't heard of these before.

Dipping also weakens the glue, and doors aren't always as stable afterwards.

Now as to sand blasting, could you reduce the airflow to make it lesss agressive.

with dipping it depends on how good the dipper is and whether he's lazy or not. If dipped for the right amount of time, joints should stay fine but it takes a bit more effort with the scarper to get them clean. Alternatively you can leave them in for longer, all the paint falls off by itself, glue can break down, grain opens up, doors swell all over the place and twist as they dry.
Again sandblasting depends on the skill of the blaster as to how much damage will be done to the substrate.

Soda blasting is common with classic car/bikes and aircraft as it uses bicarbonate of soda. That's because sand/walnut shell/ plastic beads stay behind on the piece. Soda is very gentle and just water washes/dissolves any media left behind.
When friends bought old parquet flooring they hired a guy to dry ice blast the tar from the back.

Take a look on google- using any material that stays on the original is an issue
