Being straight about limits builds more trust than pretending. Interior lacquer is an interior product — with one covered-loggia asterisk.
The exposure spectrum
Fully open patios: marine-grade polymers, stainless or teak — interior MDF systems do not belong, ours included. Deep covered loggias behaving like indoor-outdoor rooms in dry climates: interior-grade fronts have served, with the owner accepting furniture-care rules.
Why the line exists
UV dose, temperature cycling and wind-driven rain attack coatings engineered for kitchens; warranty honesty means we call the boundary rather than discover it with your client.
The workable pattern
Outdoor-rated carcass systems for the grill run, with the adjacent indoor servery — bar, glazed uppers, panel fridge — in full lacquer program visible through the sliders. Continuity of colour across the threshold delivers the design intent safely.
