Instructions

 

› Which colour should I choose?

 

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.

  • Grassland Beige is the natural look for pine, douglas, larch & teak.
  • Rocky Umber is the natural look for thermo pine & cumaru.
  • Foxy Brown is the natural look for iroko & ipé.

 

 

› 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 (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.

 

 

› In 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.
  • 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).

› Maintenance

 

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
Tips & Tricks
  • 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.
Consumption

Estimated coverage: 8 to 15 m²/liter*

*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.

 

DuroGrit is a sustainable, wood fibre fortified and water-soluble oil that colours and protects all exterior wood in 1 single layer. The patented 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.

DuroGrit

Rubio Monocoat has always been an innovative player on the market. With our new patented FibreGrit Technology, we are once again proving our relevance in the wood protection sector. DuroGrit consists partly of long cellulose fibres from wood itself. These fibres are water-repellent, very strong and hard. This means that they make your coating harder, strengthening the wear resistance and making the product suitable for terraces, garden furniture, etc.

In addition, these fibres form a grid to hold the UV stabilisers. This allows us to add more UV stabilisers, resulting in much better UV resistance. The larger amount of UV blockers and the protection this provides are revolutionary.

Thanks to this unique technology we can offer a product with a natural look on wood that is extremely durable. It provides a very good protection from UV light, while still being a very ecological product. Rubio Monocoat’s DuroGrit really is tomorrow’s durable UV protection for your outdoors.

* Standard spread rate is 8-15 m²/litre, however consumption can vary a lot depending on your 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 litre per m². You can use the leftover to maintain and touch up the surface with the same product. In exceptional cases, e.g. on very weathered or highly absorbing wood, consumption can be twice as high (even up to 6 m²/litre). In these cases, adding up to maximum 20% water can help control the spread rate.

Customer Questions
Can DuroGrit be applied on every wood type?

Yes. Colour advice does vary based on wood type, so we recommend taking a look at our DuroGrit colour advice chart for several wood species to find the colour that works best for your wood type.

Can we apply a second layer of DuroGrit for an even better protection or more intense colour?

DuroGrit is a one layer product. When two or more coats are applied, the UV protection will be improved but the system will also become more film-forming. This might result in typical problems of film-forming systems such as flaking/peeling. In addition...

How can we remove overlapping of DuroGrit?

Small errors can be touched-up on the wet surface up to 15 minutes after application, depending on the weather conditions. Apply a bit of extra DuroGrit with a brush. Put some pressure with your brush to dissolve and mix the old product with the new ...

Does the addition of Open Time Extender affect the UV and/or mechanical resistance of DuroGrit?

No, but make sure to add no more than 10%.

What are the minimum and maximum temperatures in which we can apply DuroGrit?

Do not apply below 10°C or above 30°C.

How many product of DuroGrit is used m²/L?

8-15 m²/litre. Consumption strongly 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 the recommended...

Is it really required to let new wood age for 4-6 weeks before applying DuroGrit?

This is more of a recommendation than a hard rule. It mostly depends on the particular wood used. For example, fresh cumaru wood would definitely benefit from a few weeks of weathering to rinse out the extracts that the wood contains. After all, these...

What is the total drying time for DuroGrit?

General drying time is 1 to 3 hours. The exact drying time, however, depends strongly on the relative air humidity and temperature. Drying, in the sense of the evaporation of water, can go very fast, especially when it's windy or sunny. Usually, you...

How can I remove stains from spilled DuroGrit product on non-targeted adjacent areas?

First of all, protect the adjacent areas from spilled product by using plastic, cardboard or tape to cover up risk areas. If some product is spilled despite this, immediately remove the spilled material from non-targeted areas with soap and water. Product...

How should we handle a renovation with DuroGrit?

Clean the surface with Exterior Wood Cleaner and re-apply 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.

How can we clean a surface treated with DuroGrit?

Only use Exterior Soap (Ecospray) or All Natural Wood Cleaner (Spray). Do not use other cleaning products.

How can we clean brushes and tools that were used to apply DuroGrit?

Clean them with water, immediately after use. After multiple uses, the bristles of the brushes may start to feel a bit “oily” or sitff. In that case, you can clean the brushes also with warm (not hot!) water and mild soap or dish detergent. Another ...

Is it possible to mix DuroGrit colours?

In theory, it is possible to mix DuroGrit colours with each other. However, these new combinations may not give the same durable protection as our standard colours and may fade at a more rapid pace. Since these have not been tested in our laboratory ...

Is there also danger for auto-combustion with DuroGrit?

No. DuroGrit is a water-based product and is not made with linseed oil. Therefore, there is no risk of auto-combustion.

Can we apply DuroGrit over Hybrid Wood Protector?

Yes. Make sure to use Exterior Wood Cleaner before the application with DuroGrit. Sanding the layer of Hybrid Wood Protector is not necessary, unless the Hybrid Wood Protector layer is still very present. Keep in mind that DuroGrit is a transparant ...
