How do i prep my Bathurst home's exterior for painting when the old lead paint is flaking off everywhere?

Stop before you pick up a scraper — lead paint removal is one of the most hazardous DIY tasks a homeowner can take on, and Bathurst's older housing stock means this situation is very common.

If your home was built before 1978, there's a strong chance the original exterior paint contains lead. In Bathurst's older neighbourhoods — particularly around the downtown core and established residential streets — you're likely dealing with multiple layers of lead-based paint that have been recoated over decades. Flaking paint is the most dangerous condition because it creates dust and chips that are easily inhaled or ingested.

Before you touch anything, pick up a lead test kit from a hardware store ($15–$30) or hire a certified inspector to confirm what you're dealing with. If the test comes back positive, your approach changes significantly.

If Lead Is Confirmed

You have two legitimate paths: encapsulation or removal. For exterior work, encapsulation (applying a bonding primer specifically designed to seal lead paint, then topcoating) is often the safer and more cost-effective choice when the paint is still adhering in most areas. Removal is necessary where paint is actively flaking, peeling, or failing — you can't encapsulate what isn't sticking.

For the flaking sections, safe removal means working wet (misting the surface to suppress dust), using hand tools rather than power sanders or heat guns (both create dangerous airborne particles), containing all debris in heavy plastic sheeting, and disposing of lead waste properly. In New Brunswick, lead paint debris is considered hazardous waste — contact the City of Bathurst or RSC 3 (Chaleur Regional Service Commission, 506-542-2688) about proper disposal options, as household hazardous waste drop-off events are held periodically.

Realistically, this is a job most homeowners should hire out to a contractor experienced in lead paint remediation. Expect to pay $3,000–$8,000+ for a full exterior prep and paint on a typical two-storey Bathurst home with lead paint complications — the range depends heavily on the home's size, the extent of the failing paint, and how much remediation is required before priming.

If You're Doing Portions Yourself

At minimum, wear a properly fitted N100 respirator (not a dust mask — it won't filter lead particles), disposable Tyvek coveralls, nitrile gloves, and eye protection. Keep children and pregnant women completely away from the work area. Shower and change clothes before re-entering your home. Never dry-sand, dry-scrape, or use a heat gun above 1,100°F on lead paint.

The Painting Sequence Once Prep Is Done

After all loose and flaking paint is addressed, you're looking at: spot-prime bare wood with an oil-based or shellac primer (it grips better than latex on weathered wood), caulk all gaps and joints, then apply two coats of a quality exterior latex. Given Bathurst's coastal proximity to the Chaleur Bay and the salt air and moisture that comes with it, choose a paint rated for high-humidity environments — premium brands like Benjamin Moore Aura Exterior or Sherwin-Williams Emerald hold up significantly better in Atlantic conditions and are worth the extra cost per gallon.

The best window for exterior painting in Bathurst is June through September — you want consistent daytime temperatures above 10°C and at least 48 hours without rain after application.
