If you ever pass this way on your travel`s i could lend you a pressure washer,work`s fine sucking from a water butt,looks ancient compared to today`s jobies,its in a barrow frame ,ex dairy farm,
Just count the number of leg`s on chairs before using,lol,its a 12-15 l per min.

That is what they use to strip doors, etc: a big bath of the stuff.
I have assumed that paint strippers have a similar active ingredient.
Depending on the type of paint & the object to be stripped ie a door gets dunked in a bath of hot caustic solution...that's normally the powdery/granular stuff
If you're stripping paint from beams, stairs, or the front of a building, the powder or flake is mixed with another ingredient the name of which escapes me, in order to make it thixotropic

The details are not relevant to how fast it eats aluminium.

Hot caustic will attack aluminium with greater vigour than the paint.

oops i hadnt noticed the chairs were ali,caustic will eat them .
nitromors is expensive and vile to use so sand blast seems a good option.
iirc the kit can be hired for stone cleaning or a firm that does fancy sand blasted frosted glass might do em for a fee

Even if the chairs are ali, firstly the caustic paste option is cold; & as mentioned previously, a test patch is always the best idea
I worked for the manufacturer of this stuff & it works very well if care is taken
The "strength" of the paste can be regulated...
Try a test patch for 5 minutes & you will see if the paint blisters or not

Well. Caustic works but only removes the top layer which looks like plain emulsion. The original paint is much harder to shift but painting over will solve that.
Nitromors also worked but carries with it a price tag of three million pounds.
Nitromors leaves them shiny like new cast aluminium but hydroxide goes dull grey.
I'm going to get a price for shot blasting.
I have six to do and each is a back, seat and four legs. A seat and a back have taken an hour or two and aren't very good.
The chairs were a fiver each from a cafe but very handy in the new garden, surrounded by creeping thyme and palm trees.
Thanks for the suggestions.

£60 to strip them all, £90 to strip and powder coat. Do I assume this is essentially 'priming' them, ready for me to paint as required?

I thought powder coat would be in the finish/colour you desire. The powder is applied electrostatically and then chairs are backed for the finish to set IIRC. Seems a good price to save time and effort, and achieve a quality finish.

Yep powder coating is generally the finished product done to the desired colour

I'd go for it if I were you.
Alternatively, use Langlow Strip Away Pro.

thirded on the strip and powder coat
seems a bargain especially if you can choose the colour/s

Hm. Strikes me as a deal. Just need to convince her that the colours he has on offer are fine. Wonder if he has one of those Dulux machines that makes every shade under the sun.

Look online for a ral colour chart

Have seen. Have hope.

I have a ral colour chart if you want it.

Thanks, but I think the answer is to go visit the bloke and have a chat.

Probably.

The caustic soda will leave a layer of alumina on the surface. This will need to be removed before any other work is done. Hope the shot blasting and powder coating goes well, as it seems the best answer.
