hot air gun?
Cheaper and easier to buy new skirting its cheap, i bought all new stuff and was surprised how cheap it was.
Your very unlikely to scorched the wood with a hot air gun, if you keep it about 75mm -100mm away from the wood.
And also wear gloves, very painful getting hot paint flakes on your hands.
Cheap skirting looks cheap though, under the paint there could be some nice wood in his grannies house.Cheaper and easier to buy new skirting its cheap, i bought all new stuff and was surprised how cheap it was.
