Tomorrow’s UV protection for your outdoors
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 resistant.

*Consumption depends on the type of wood, weathering and preparation. Old wood, wood that has been left untreated outdoors or grooved wood often absorbs more product. Therefore, always purchase slightly more product than for the recommended liter per m². You can use the leftover to maintain and touch up the surface with the same product.
INFORMATIONAL IMPORTANT
• For the best results, we advise staying as close to the natural look as possible. Going lighter than the natural colour of the wood may shorten the durability of the protection. If you want to create a look that contrasts a
lot with the natural colour of the wood, please keep in mind that scratches may become more visible because of said contrast with the wood. This might happen especially on deckings.
• The pigment present in the various DuroGrit colours helps protect the wood from greying. PLEASE NOTE: Although DuroGrit offers state-of-the-art UV protection, the result still depends on the
chosen colour and wood type. As a rule of thumb, the darker the colour, the better the durability. Some wood types, especially thermally modified wood, are extremely sensitive to colour change due to exposure to UV light. For these wood types we recommend using a dark colour.
• We advise to use the white and pastel colours on softwood only.
APPLICATION INFORMATION
Instructions
On new wood
Step 1: We recommend allowing the new installed wood to weather outdoors for about 4-6 weeks (except oak)
• When this is not possible, sand the wood scratch-free with a screen 80 grit to open the wood pores.
• Allow already installed new wood or wood containing natural wood extractives (oak, red cedar, afzelia, redwood, …) and especially hardwood (ipé, teak, merbau, …) to weather outdoors for about 4-6 weeks. This will allow the water-soluble substances to come out of the wood and will allow the wood to absorb the DuroGrit better.
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
• Only work in frost-free and dry conditions and avoid application of DuroGrit when rain is expected within 10 hours of application.
• Stir the product a few minutes before use.
• Apply the product evenly to the surface with a soft, synthetic brush made for water-based products. 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). Tip: Maintain a wet edge to avoid overlaps.
Errors created during application (start marks, brush marks, overlaps, …) can be touched up on the wet surface up to 15 minutes after application (depending on the weather conditions). Apply a little extra DuroGrit on the mark. Put some pressure on your brush so the product that has already been applied dissolves and mixes with the new one. Finally smooth out until you no longer have brush marks.
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)). Keep in mind that low temperatures, low ventilation and high humidity significantly slow down the drying and curing
process.
Case of renovation on older non-Rubio Monocoat products
Step 1: Remove all residues of old applications
• Remove all residues of old applications by sanding the surface scratch-free. End with a screen 80 grit, do not sand smoother. The smoother you sand, the less product can penetrate in the wood and the less intense the colour (and protection) will be. Is your wood too dirty to start sanding right away? Then first clean it with either water or Exterior Wood Cleaner (see step 2 for instructions). By already removing a lot of dirt beforehand, your sandpaper won’t get clogged up right away when sanding.
Step 2: Clean the surface with Exterior Wood Cleaner and let it dry
• First wet the wooden surface with a fine mist of water.
• 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 and thoroughly rinse off the cleaning solution residue with clean water until all foaming residue is rinsed away.
• Allow the surface to dry completely.
Step 3: Apply DuroGrit
• Only work in frost-free and dry conditions and avoid application of DuroGrit when rain is expected within 10 hours of application.
• Stir the product a few minutes before use.

For vertically installed boards, this means from top to bottom and for horizontally installed wood from left to right (or vice versa).

Maintenance Instructions
Cleaning instructions
Regular cleaning can be done with Exterior Soap (Ecospray) or All Natural Wood Cleaner (Spray). Do not use any other cleaning products or detergents as these might affect the protection!
Maintenance instructions
In general we recommend a yearly visual check-up just after winter season. Please check for the presence of the following two points:
a. Dirt & green deposits; clean with low pressure water and a soft brush or use Exterior Soap/All Natural Wood Cleaner (consult Technical Data Sheet before use)
b. Fading of colours
If necessary (concerning point b) apply a maintenance coat according to the instructions. First clean your wood with Exterior Wood Cleaner, then apply a layer of DuroGrit in the original colour. Depending on the degree of fading of the colour, dilute DuroGrit with maximum 20% water to avoid applying too much product and making the colour too opaque. The frequency of maintenance depends on the weather conditions, exposure, geographical situation, solar orientation, wood type (softwood vs hardwood) and colour. In normal weather conditions:
• Vertical surfaces: every 3-5 years
• Horizontal surfaces: up to 2 years
• To determine the desired colour, always do a small test first with one of our samples on identically sanded and prepared wood.
• A good preparation is crucial for good protection. Always prepare the wood with Exterior Wood Cleaner, including if the wood is new.
• Stir the product well before application. When using several containers at one site, it is recommended to mix them for an even result.
• Avoid direct sunlight on the surface during application and only work in frost-free conditions and when weather conditions are dry.
• 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.
• Do not cover and do not place heavy objects on the surface until it is completely cured.
• Only use our maintenance and cleaning products.
• Our products are developed with environmentally friendly ingredients. However, some people can be allergic to certain elements. Therefore, we advise wearing gloves during application to protect your skin.
• Tape off first and work between the grooves. Tape off anything that should not be treated, splashed, smeared or spilled on, including anything sensitive to overlaps.
• The product can also be applied with a spray gun.
