Use of CosmetiWood

How to use?

For good adhesion results, it is important to prepare knots and cracks by removing any loose parts such as bark fragments and making sure the wood is dust-free.

Tidying up cracks is not recommended since the natural look will be lost as a result. Firmly and deeply fill the crack or knot and leave to dry. Depending on defect size, defect depth,  temperature and relative air humidity, air flow;  drying takes mostly 4 to 24 hours.

Is there a machine available for filling up the wood

CosmetiWood was developed by CSP Engineering, who offer a broad range of machines for automated application of the product, in volumes ranging from small-scale to industrial production. For more details visit: www.csp-engineering.com

Do you have manual aids?

With the aid of semi-rigid spatula's and the Dispensa dispenser, application of CosmetiWood becomes easier, cleaner and wasteless.

Up to what size and depth can I succesfully apply CosmetiWood?

CosmetiWood can be used in the top layer of engineered flooring, veneer as well as in solid wood. In principle, there is no limit to the depth and size of cracks and knots to be filled.

Can I also use CosmetiWood for artistic purposes, such as imitating tree bark?

CosmetiWood is not self-supporting in principle, but it can be used to apply sculptures and create effects, such as tree bark.

CosmetiWood in fine cracks... will it work?

Netvertheless its pasty nature, CosmetiWood can be used for fine cracks. 

Can I fill up insect holes with CosmetiWood?

Just like fine cracks, small holes are certainly suitable for filling.

When applying CosmetiWood, I spread the filler wider than the defect. Is that a problem?

When applying CosmetiWood, it is common to fill around the defects with a thin layer which can then easily be removed with sanding.

How should I go about repairing large defects?

When working manually, there is no limit, in principle, to the size of the defect. Be aware that CosmetiWood is a cosmetic filler and does not create structural strength. It is recommended for deep defects to apply the CometiWood in several layers and allow each layer to dry.

Is there a maximum depth to which CosmetiWood can be used?

As long as the defect is properly filled, there is no limit, in principle, to the depth when using CosmetiWood. For deep cracks, it is nevertheless recommended to apply the product in several layers and allow each layer to dry.

Can I apply CosmetiWood to painted, stained or oiled wood?

Yes, you can, although it is recommended to clean and sand the wood thoroughly before applying the product, and to check the compatibility between the product and the wood.

Can I use CosmetiWood to fill shallow defects or on veneer?

It is possible to apply CosmetiWood in very thin layers.

What is the best way to clean?

Excess product and tools can easily be cleaned off with water. Once the product has hardened, any residue can be removed mechanically – for example, by sanding.

Drying and hardening

How long wil it take to dry? Can I speed up the process?

CosmetiWood dries by evaporation of its water content. By raising the ambient temperature, creating air flow over the CosmetiWood, and lowering the relative air humidity, drying is faster.

Can I harden CosmetiWood with UV or infra-red light?

CosmetiWood is a single-component product that does not harden under the influence of UV. While heating with infra-red may reduce the drying time, it is still important to leave sufficient time for the product to dry in depth.

Finishing

Can CosmetiWood be milled?

Once the product has fully hardened, CosmetiWood can be milled like wood, without any risk of crumbling.

What is the best way to sand CosmetiWood?

CosmetiWood is easy to sand with all common abrasives.

Does CosmetiWood absorb colouring?

CosmetiWood absorbs colours well, albeit not to the same extent as wood. Since the product is available in different colours, a good match is available for each application to either camouflage or accentuate the filled parts, according to the user’s wishes.

Which finishing products should I use?

CosmetiWood is compatible with most industrial finishing products. However, we recommend first testing the product’s compatibility for specific applications.

Can I brush CosmetiWood or artificially age it? How should I do this?

CosmetiWood has a hardness and durability that very closely approximates that of wood. Therefore, ageing techniques that are applied to wood can also be applied to the product after drying.

Product

Is CosmetiWood suitable for outdoor applications?

CosmetiWood is suitable for outdoor applications, provided that appropriate coatings are used, whose compatibility must be tested beforehand for each application.

Which colour is the most suitable for my application?

CosmetiWood comes in different colours, allowing the user to choose between camouflaging or accentuating filled cracks and knots. The finishing layers that are subsequently applied must be considered when choosing the most suitable colour.

Can CosmetiWood be produced in a custom-made colour?

A custom-made colour can be developed and produced. Minimum production quantities apply. Please get in touch by mail or phone for further information.

Is CosmetiWood dangerous to use? Will any toxic fumes be released?

CosmetiWood does not contain toxic components. Please refer to the safety data sheets for more information.

Can you tell me more about "sustainability", the green aspect of CosmetiWood?

More than 70% of the CosmetiWood ingredients are natural products. In addition, CosmetiWood contributes to sustainable use of wood since the wood filler makes it possible to valorise wood with cracks and knots into a high-quality product.

What sets CometiWood apart from classic wood fillers?

CosmetiWood is characterised by its ease of use and zero shrinkage. It has a pleasing structure that can be treated like wood and guarantees proper adhesion and absorption of finishing products. 

For full details see the product pages: CosmetiWood MAX  or CosmetiWood PRO

What is the difference between CosmetiWood PRO and CosmetiWood MAX?

The two versions differ slightly in processability. The PRO version has a very high viscosity and can be used under high pressure in our PAR filler machines for machine filling of defects. The high viscosity of the PRO ensures that even for very large defects, the material is nicely distributed without excess material to guarantee the best result. The thixotropic behaviour (the material becomes more fluid under pressure) of the Cosmetiwood PRO ensures that even small defects and hairline cracks are properly filled. It can be uses manually also. Please consult us for more information.

The MAX version, specially developed for manual use, has a lower viscosity and very good spreadability . This allows effortless and fast work without sacrificing drying time (see drying time) or other properties. With adapted machine settings, CosmetiWood MAX can be used for automatic filling. Please consult us for more information.

How do I recognise a quality wood filler?

A quality wood filler such as CosmetiWood does not shrink during drying and is sufficiently hard and wear-resistant without any loosening or crumbling during processing. A good wood filler behaves like wood and is compatible with it and, therefore, adheres properly for many years.

Can I mix CosmetiWood with other wood fillers?

Do not mix CosmetiWood with other wood fillers. The specific properties that are inherent in the composition of the product can no longer be guaranteed after mixing.

Can I add water or other liquids to CosmetiWood?

Adding water or other liquids, ruins the product.

Can I mix CosmetiWood with saw dust?

CosmetiWood is sold as a ready-to-use product. Please do not mix it with other products.

What is the difference between CosmetiWood and 2 component wood fillers?

Two-component wood fillers typically result in a brittle structure with a closed surface once hardened, while CosmetiWood obtains a pleasing, woody structure during drying. Since there is no need to mix two components, CosmetiWood is also easier to use, with much less waste.

What is the difference between CosmetiWood and hotmelt fillers?

Hotmelt fillers typically shrink, tend to pop out of the defects after time, are more difficult to sand, and are more demanding on the finishing products for proper adhesion. CosmetiWood is easier in use and creates a longlasting filling.

What does CosmetiWood look like after hardening?

CosmetiWood hardens through drying, it has a earthy look and its texture blends in nicely with the surrounding wood.

Storage

How should I store CosmetiWood

CosmetiWood should be stored in a frost-free, dry environment. The product is presented in resealable packaging. Once opened, the shelf life can be increased by covering the product with plastic film to prevent air from entering the closed packaging. Once opened, cartridges can be sealed airtight with a tie-wrap or a suitable bag clamp.   

What is the shelf life of CosmetiWood?

CosmetiWood has a guaranteed shelf life of 1 year. See the packaging for details.

Can I freeze CosmetiWood to extend its shelf life?

Tests have shown that CosmetiWood can withstand a freeze - thaw cycle. It is however not suitable for freezing. The product must always be stored frost-free during transport and storage.

What should I do with leftover product after expiration date?

Although CosmetiWood can be used beyond its expiry date if stored properly, proper functioning of the product can no longer be guaranteed. Please consult local regulations on how to dispose of product that can no longer be used.

Cost or benefit

How does the cost of CosmetiWood compare with that of other wood fillers?

CosmetiWood offers added value during production, in sales, and during the full life to the wood product. 

Value in production means that there is only 1 application needed, there are no air bubbles, sanding is easy, there is no waste and the  demands on finishing product are low.
