Golden rule to fol­low in re­paint­ing

Weekend Argus (Saturday Edition) - - PROPERTY - ROB PAD­DOCK

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-

aged on first use or their op­er­a­tion will be re­stricted in some way.

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.
