DuroGrit is a sustainable, wood fibre fortified and water-soluble oil that colours and
protects all exterior wood in 1 single layer. The FibreGrit Technology, where added wood
fibers give the oil its unique structure, provides the perfect combination between a
saturating and a breathable monocoat system.
Thanks to this technology, the product does not only have an incredible and long-lasting
UV protection compared to other exterior wood finishing products, but it’s also
extremely durable and wear resistant.
Instructions to apply DuroGrit
- Step 1: Allow the new installed wood to weather outdoors for about 4-6 weeks (except oak) or sand the surface
- Step 2: Clean the surface with Exterior Wood Cleaner and let it dry
- Step 3: Apply DuroGrit
- Step 4: Let dry for 3 hours
Step 1: We recommend allowing the new installed wood to weather outdoors for about 4-6 weeks (except oak)
- In case of new wood that contains natural wood extractives (red cedar, afzelia, ...) and hardwood (ipé, teak, merbau, ...) weathering will allow the water-soluble substances to come out of the wood and will allow the wood to absorb the DuroGrit better.
- When natural weathering is not possible, sand the wood scratch-free with a screen 80 or 100 grit to open the wood pores.
- In case of unfinished but heavily weathered wood, we recommend you to sand the surface because sanding will help you to get a more uniform end result
Step 2: Clean the surface with Exterior Wood Cleaner and let it dry
- First wet the wooden surface with a fine mist of water from a garden hose.
- Clean the surface with Exterior Wood Cleaner and a stiff bristled nylon scrubbing brush (wear gloves and eye protection).
- Do not allow the solution to dry. Thoroughly rinse the cleaning solution residue with clean water until all foaming residue is rinsed away.
- Allow the surface to dry completely.
Step 3: Apply DuroGrit
- Tape off anything that should not be treated, splashed, smeared or spilled on,
including anything sensitive to overlaps - Stir the product a few minutes before use. When using several containers at one site, it is recommended to mix them for an even result
- In case of rough/weathered wood, highly absorbent woods or for terrace application, you can add up to maximum 20% water to the DuroGrit for a better spreadability of the product.
- Apply the product evenly to the surface with a soft, synthetic brush made for water-based products.
- First treat hard to reach spots like edges
- Work in the direction of the wood installation, always covering the full length. For vertically installed boards, this means from top to bottom and for horizontally installed wood from left to right (or vice versa). So never stop in the middle of a board but only at a natural break (e.g. a seam, edge, staircase, etc.).
- Work in small sections of about 1 or 2 boards wide.
- Always apply sufficient product and brush again afterwards to avoid start/stop and brush marks (remember not to exert too much pressure on the brush)
- Maintain a wet edge to avoid overlaps.
Step 4: Let dry for 3 hours
- Let the surface dry for about 3 hours. Complete curing takes place after 3 days (at 20°C (68°F)).
- Do not cover the surface or don't place heavy objects until the surface is completely cured
- Keep in mind that low temperatures, low ventilation and high humidity significantly slow down the drying and curing process.
Tips & tricks
- Only work in frost-free and dry conditions and avoid application of DuroGrit when rain is expected within 10 hours of application.
- Avoid direct sunlight on the surface during application
- To determine the desired colour, always do a small test first with one of our samples on identically sanded and prepared wood.
- Only use our maintenance and cleaning products.
