A Titirangi homeowner’s Butynol deck had developed leaks caused by protruding nails working up from the plywood below. Goliath Coatings attended, set the nails, sealed all joints around the perimeter, and confirmed the seams of the existing Butynol were sound — then overcoated the whole deck with Mapei Aquaflex Roof Premium for a fresh, fully-sealed finish. The leaks were stopped and the client loved the result. It’s the kind of balcony and deck membrane repair and re-waterproofing Goliath Coatings delivers across Titirangi and Auckland.
