We imagine that you will have all witnessed qualified painters and decorators using a blow lamp to strip paint from windows and doors, and they look it really easy don’t they? There can be no doubt that removing layers or old paint can be very desirable as it gives you a chance to get back to the woodwork and provide an excellent surface which in turn will make the fished project look much better.
Removing old paint by this method is not difficult, but the first thing to say is unless you are very proficient using a blow lamp, a hot air gun is far better. Wear goggles and a dust mask when burning off paint and one thing to remember is that if your house is an old one then you are sure to have lead paint on the woodwork. Up until the mid-1960s, lead was widely used in household paint; this can be dangerous if breathed in, especially by children.
By using a hot air gun the paint will be melted with the heat and as it bubbles a scraper is used to remove it. If you are using a blow torch take extra care, hot air guns are less likely to scorch the wood. Special care must be taken when stripping paint on window frames as the heat can crack the glass, expensive in any case, but more so if these are double glazed units. Use a heat deflector shield to direct the hot air away from the glass, if you do not have a special deflector shield than a plasterer’s float will work, but do not let this touch the glass or the heat will still be in contact with the glass.
