Just like how wooden furniture need refurbishing from time to time, those of metal such as a gate, a roof vent or that fence on your yard need repainting too. A couple of well-applied coats should not only freshen up your fixtures’ look but should also reinforce and protect your substrate from environmental factors that weaken metal.
So, gather up your materials, the right paint for metal and let’s get to painting!
KINDS OF METAL
Repainting metal surfaces is a lot similar to painting concrete or wood. It is important to understand however that metal has a different makeup than those of wood and concrete. There are two kinds: ferrous (with iron) and non-ferrous (without iron). It is important to establish where the metal you’re dealing with falls into, as this should be a deciding factor in what specific type of paint for metal to go for.
A simple trick to find out if your metal is ferrous or non-ferrous is to use a magnet. If it’s ferrous, the magnet should stick to any part of the surface. A clear indication that your surface is not ferrous is when nothing happens.
True to any paint job, surface preparation is key.
- If it’s previously painted metal you’re tackling, sand or use a wire brush to completely remove the old paint and rust off of it.
- Apply metal primer that suits the type of metal you’re dealing with.
Although some professionals advise on skipping the primer step with pre-painted substrates, pushing through with it ensures that your paint for metal adheres well and lasts longer than normal.
Basic chemistry tells us that ferrous metals rust and corrode. Stainless steel has a layer of oxide that makes it material counters stains, rust and what have you. It should follow that the kind of primer that’s best for a paint job involving ferrous metal or iron is one with oxide.
