If your DIY oven will live outdoors, this is the “insurance policy” for the outside of the dome. It’s a simple, proven coating system that helps seal the render, reduce hairline cracking, and protect the finish from NZ sun and weather - so the oven stays drier, looks better, and holds performance for longer. What it protects against Rain soaking into the outer shell Hairline cracks showing through over time UV fading and surface chalking Moisture getting into insulation (the real performance killer) How it works (3-step system) Penetrating primerSoaks into the render and improves bonding - creates a strong “root system”, helps everything stick long term. Weather-tight membraneA protective layer that moves with the dome during heat cycles and bridges small hairline cracks. UV + water-repellent top coat - BlackProtects the colour and surface from harsh sun and weather, and helps keep the dome sealed and water-shedding. What’s included Pre-measured products for one oven dome (primer + membrane + top coat) Tool Pack: paint tray + 3 rollers + disposable gloves Simple step-by-step instructions (so you don’t have to guess thickness or timing) Best for Ovens kept outdoors year-round Rainy, windy or coastal locations Anyone who wants a premium finish and long-term protection (not a “quick paint job”) Important notes (so it works as intended) Apply only to a dry, cured outer render (never to damp render) Don’t rush the first firing - allow 3 days after the final coat before lighting the oven Touch-ups are easy if the dome ever gets chipped (keep leftovers)
