Anybody have experience of removing dried paint on the wall with chemicals?

oxygen works really well.

Someone correct me if I am wrong, which I may be, but aren't hardware/paint stores loaded with chemicals with the sole purpose of removing paint? :)

Ask anywhere, how do you remove paint from the wall? comercial paint strippers are full of chemicals.... DCM mostly.

Some people don't like solvents in huge amounts airborne. Potassium hydroxide or sodium Hydroxide seem to make house paint peel anyway.

thank u guys. what is the main component in the paint stripper thing?

kwpooh - 15-3-2005 at 17:50

really. it would be very nice to use aceton. at least it is not so toxic like dichloromethane.

Then use acetone! (keep in mind it's spelt 'acetone', not 'aceton' )

As said sodium hydroxide makes quick work of paint. Hardware stores sell TSP (tri sodium phosphate) it comes in a box in the painting department. Sometimes it's not really TSP but something similar so it's more of a type of paint remover then a specific chemical. Anyway, dissolve it in water, wear gloves and wipe down your walls. Then scrape off. Not sure how well it works on paint but it works good for wallpaper.

Hmmm... sounds the same as a product here called 'Sugar Soap'. In a house I was in 4 years ago, I had to help strip the walls and re-paint. I've got no idea whats in sugar soap, but it sounds similair to the TSP BromicAcid describes.

Most paint strippers I have seen sold in paint and hardware stores contain something like 60% CH2Cl2 dissolved in petroleum jelly.
