Halifax's heritage stock (including Downtown Halifax Waterfront) typically requires pH-neutral chemical gel (pH 6.5–7.5) with 30–60 minute dwell time — acidic strippers dissolve mortar calcium and leave white efflorescence on wood. We pre-test an inconspicuous patch before treating the visible area, with all rinse water captured to meet local stormwater rules.

Halifax receives 1468mm of annual rainfall, which causes spray paint to penetrate porous surfaces like wood, brick, stone rapidly — making prompt removal essential before paint bonds permanently.
