Exterior timber doesn’t fail because people don’t care — it fails because the system wasn’t right from the start.
Ilva Unico HTMB is a true 3-in-1 exterior timber coating designed to simplify the process while improving long-term performance. In three coats, you isolate, seal, and protect — using one water-based product that remains transparent to showcase the timber grain.
For contractors, manufacturers, and serious DIYers, that means less complication, fewer products, and a more predictable finish.
The first coat of Unico penetrates and acts as an isolator — and this is critical in exterior systems.
An isolator:
Instead of adding a separate primer, Unico builds this protection into the system itself. That’s what makes it a genuine 3-in-1 product — stain, sealer, and topcoat.
Unico is a mono-component, water-based exterior coating formulated for real-world use on windows, doors, pergolas, trellises, gates, awnings, and outdoor furniture — on both softwoods and hardwoods.
It dries quickly, has excellent vertical hang (meaning you don’t have to lay everything flat), and levels beautifully to deliver that distinctive Ilva eggshell finish — refined, smooth, and professional.
Application is flexible. It can be sprayed, rolled, or brushed, making it suitable for workshop production lines or on-site application. Coverage is strong, clean-up is simple, and odour is low thanks to its ultra-low VOC formulation.
Unico is fully tintable while remaining transparent enough to showcase grain clarity. Our stain team has recently developed additional exterior shades including:
Alongside the colour range, Unico is available in natural clear finishes — Matt and Satin — allowing you to retain the timber’s original character while still benefiting from full exterior protection
The combination of colour flexibility and reliable weather resistance makes it suitable for architectural projects where appearance matters just as much as durability.
Ilva Unico simplifies exterior timber finishing without compromising performance. It isolates, seals, and protects in one system, dries fast, applies easily, and delivers the refined finish Ilva is known for.
