Durable, Eco-Friendly Wood Finishing with Rubio Monocoat DuroGrit

Rubio DuroGrit is a sustainable, wood-fibre fortified and water-soluble oil that colours and protects all exterior wood in a single layer. The FibreGrit Technology, where added wood fibres give the oil its unique structure, creates the perfect combination of a penetrating and breathable monocoat system. The resulting finish is an extremely durable and wear resistant exterior solution which delivers incredible and long-lasting UV protection.

The standout feature of DuroGrit is its non-film-forming protection, which allows the wood to retain its natural look and feel while guarding against moisture, stains, and abrasion. Unlike traditional polyurethane finishes, DuroGrit doesn’t require sanding between coats, reducing labour and preserving more of the original timber character. It bonds with the top microns of the wood fibres, making it less prone to cracking or peeling over time.

This finish is also environmentally conscious, containing 0% VOCs and meeting stringent European standards for indoor air quality. It’s safe for use in residential, commercial, and even child-sensitive environments like schools or nurseries. Rubio Monocoat offers DuroGrit in a curated range of colours that highlight wood grain while providing long-lasting performance without the need for frequent reapplication.

FAQs

What makes DuroGrit different from standard Rubio Monocoat oils?

DuroGrit offers increased abrasion and wear resistance compared to standard Rubio Monocoat finishes, making it ideal for exterior applications. It maintains the same molecular bonding technology but enhances durability for demanding environments.

Is sanding required before applying DuroGrit?

Yes, proper sanding and surface preparation are essential for optimal bonding. The final sanding grit typically ranges from 100–150 depending on the wood species and desired texture. No sanding is required between coats since only one coat is needed.

How long does DuroGrit take to cure?

While the surface is dry to the touch within 24–36 hours, full cure typically occurs after 5–7 days. During this time, it’s best to avoid standing water and heavy use of the surface to ensure proper hardening.

What maintenance does a DuroGrit finish require?

Routine cleaning can be done using Rubio Surface Care products, which are designed to maintain the finish without damaging it. Over time, high-wear areas can be spot-treated without needing to refinish the entire surface.

Can I apply a second coat for added protection?

No, DuroGrit is designed as a one-coat product. Applying a second coat will not bond correctly and may result in uneven sheen or performance. Its molecular bonding ensures a strong, durable finish in just one application.

What colours are available in the DuroGrit range?

DuroGrit is available in a selection of natural-looking tones designed to enhance wood grain. Popular colours include Pure (clear), Charcoal, and various greys and browns. These can be used as-is or in combination with Rubio Pre-Aging stains for customised results.
