Golden rule to follow in repainting
A GOOD paint job will protect your building from the elements and the golden rule of repainting is to hire a professional contractor.
Repainting requires thorough preparation and depends on the condition of the original paint and the material itself. In the case of paints, a gram of prevention is worth much more than a kilogram of cure. If the paint is still relatively new (three to five years), in most cases it can be lightly sanded or wire-brushed and a fresh coat of paint applied over the old. This is only true if the original paint is well bonded to the plaster, wood or metal to which it was applied, and if the respective material is still dry and in good condition.
In the case of window and door frames, if water has saturated the painted material, it is likely that the paint has loosened. If this is the case, the wood must be stripped, permitted to dry and may even have to be replaced if it is damaged. The situation with rusted steel is similar. Rust flakes will lift the paint off the steel surface, requiring the removal of the old paint and rust before repainting.
It’s wise to schedule a major repainting project in the late spring or early autumn, when temperatures are not expected to be extreme. Paints and coatings are temperature-sensitive when being applied. Check the manufacturer’s directions for application temperature because they vary. For example, most water-based paints should not be applied when it is cold (below about 7°C) because it will not harden. They should also not be applied when it is too hot (above 35°C) with low humidity, because the paint could dry out to a powder before it can cure to form the protective film desired.
Some parts of your home may have been coated in a factory and may require removal and recoating in a factory with special processes not available to home owners or average paint contractors. Examples include metal doors, railings, some flashing metal and fixtures.
Moving and sliding components like window sash perimeters and weather seals should not be painted. The paint will most likely be dam-

You should budget and tentatively plan to repaint every five to seven years, unless you detect problems that arise sooner. The plan should be scheduled with the contractors designated to perform the service.
