bamboo wood – technical information
What’s the difference between single-layer and multi-layer panels?
Po rozcięciu wzdłuż łodyg bambusa, powstają listewki, które po sklejeniu i sprasowaniu tworzą klejonkę bambusową, czyli płytę jednowarstwową. (klejonka=płyta jednowarstwowa). Układając kolejno wzdłuż i w poprzek kilka klejonek a następnie sklejając je i sprasowując, tworzy się sklejki wielowarstwowe.
How strong is bamboo? (To what can it be compared?)
From a botanic point of view bamboo is a species of grass – though quite extraordinary. It grows much faster than trees – even 1 meter per day; it is about 10% harder than oak tree, but still needs only casual tools for working on it.
Plywoods made of bamboo have wide range of applications. And if conserved well, they can endure in any harsh conditions (high temperatures, humidity, changing conditions).
Is bamboo wood?
According to expertise from Institute of Wood Technologies (Poznań, 25.06.2010) bamboo plywoods are classified as wood. This classification makes sense also from practical point of view: bamboo wood is a subject to similar threats as normal wood, e.g. cracking. Prevention is also similar – you can use the same oils, varnishes and waxes as for other wood.
How do you stain bamboo plywoods?
Bamboo wood is stained in a completely natural way, namely by caramelization of sugar contained in bamboo fibres. The longer you treat it with temperature (by steaming), the darker the wood becomes. What is crucial here is that the colour is absorbed by whole plywood (not only surface as it is with standard staining or varnishing) – thanks to this property bamboo doesn’t change it colour while using (when the surface layer is gradually rubbed out)
What certificates does your plywood have?
Our material has FSC certificate (Forest Stewardship Council), which guarantees that the wood comes only from forests managed in an ecological and sustainable way, protecting its pristine richness and biodiversity. Buying products with a FSC certificate you make a conscious and responsible choice.
Do you have a technical card of your bamboo plywoods?
Sure, the technical card is available here.
Are bamboo plywood good for health?
Answer is simple: YES. All our products have E1 formaldehyde emission class. Also, it’s possible to produce on order plywoods with E0 class. E0 means that the wood can be used for food-purpose products or children-friendly equipment. Moreover, you can easily find many researches about bactericidal and antiseptic properties of bamboo fibres.
Why sometimes after cutting multilayer plywood you can see cavities in the section?
Inner layers of multilayer plywoods consist of many bamboo slats, which can create little cavities inside whole plywood. If after cutting the plywood the little cavities on the side of it are visible, we recommend to fill them in with wood filler and smooth it down. Usually when you order from us plywood already cut, we fill cavities in. If you cut it on your own, you can buy a proper wood filler in our store.
Is the colour of plywoods really the same as in the photos?
Bamboo means natural. Each plywood then can slightly differ both in its structure and colour. It consists of numerous slats compressed together – each of the slats of thousands of strands. That’s why it has such a non-uniform, organic structure – and this is what makes the material exceptional.
For the same reason plywood colours presented on our website have only illustrative purpose. If you would like to make sure the colour suits you, please, check our testers before you make the order. For that purpose you can visit our office or order the tester via our website.
Will oiling change the colour of the wood?
Yes. Every rough wood has its characteristic subdued and slightly pale colour. Oil permeating into the structure, brings out vibrant colours of the wood. Due to the oiling the wood becomes a few tones darker (the darker wood the bigger after oiling). It means that e.g. oiled natur bamboo looks quite similar to the one before oiling, but chocolate bamboo or caramel gets much warmer, saturated and warm shade. That’s why it’s good idea to order our tester, oil it (it can even be casual oil you use in your kitchen – of course liquid one) and check if the colour obtained suits well your interior.
bamboo wood maintenance
If I buy a rough plywood or a counter - should I conserve it somehow?
Yes, because bamboo is wood also, and as any other natural material its structure is constantly working: the fibres contract and stretch out. This inner, invisible motion can eventually result in cracking. In order to prevent it, we recommend covering the plywood with varnish, oil or wax. If you don’t want to do it on your own, you can order already secured plywoods, ready for installation.
Varnishing: you can use any kind of wood varnishes. Dispersion varnish can cause slight raise of bamboo microfibres above the surface, especially if it is the first layer of varnish. But after smoothing and varnishing the second layer, the surface should be clean and smooth.
Oiling: we recommend to apply only very thin layers. Because bamboo wood is very dense, oil is absorbed slowly and a thick layer can cause irregular polish and long-time absorption. At least two thin layers are advisable.
How do you take care of bamboo wood?
It’s nothing extraordinary here: you can treat it as standard wood. For cleaning the surface we recommend the mixture of water with dishwashing liquid – it’s the most mild one of detergents used for wood surfaces. We disadvise using cleaners with alcohol and strong detergents – they can spoil the protective layer. It’s good to wipe the surface with wood oil once a few months (or once a year – it depends on intensity of usage). This simple treatment will endure furniture’s lifetime and protect it against external factors.
How do you oil bamboo wood?
Oiling is really nice and easy. All bamboo pieces we sell are usually prepared for oiling. It means that their surface was sanded down, dedusted, polished, the edges were finished and cavities on the sides were filled in.
Oiling in a few steps:
1. Prepare the work space: place the plywood on some cardboard or papers and bring tools needed for oiling, i.e. wood oil (in fact you can use any kind of wood oil, but we recommend to purchase proven oils we use ourselves – they are available in our online store), disposable gloves, sandpaper, cloth/ sponge / dust-free paper towel (granulation about P150).
2. Apply a thin layer of oil and spread it carefully around the whole surface. Make movements with the cloth along the growth rings. Remember to oil also each side of the counter. Check against the light if the oil was spread evenly and if there are no streaks and patches. It is really important! If you leave these streaks and bamboo dries off, they will be visible and bamboo will lose its beauty.
3. Leave the counter for drying. It will take 4 – 12h – depends on the type of oil, wood and temperature.
4. When the first layer is dried off, wipe the surface gently with sandpaper. After first oiling microfibres rise a little bit what makes the surface quite rough. Delicate sanding will remove microfibres and make the surface clean.
5. Dedust the surface. You can simply use a slightly damp cloth.
6. Cover the counter with the second layer of oil. Depending on your counter’s purpose, if its conditions are standard – two layers is enough, but if it would have frequent contact with water – we recommend three layers.
7. When it is dry, turn the counter over and repeat all the steps above.
8. Oil, after drying off, usually ossifies for a few following days, so we recommend not to use it over extensively during this time.

Except filling the form in, you can send us directly an email with your questions. Please, include in your email all following information (!) – they are necessary for cost estimation:
– technical drawing (it can be freehand) / project / size (length x wideness x depth)
– edges and corners which are to be rounded off (reminder: a counter has 8 edges and 4 corners)
– finishing: oiling / none
– delivery address (for precise cost estimation)
– telephone nr (very often we need call you to clarify certain issues – please, do not omit this information).
CAUTION: remember the first dimension is along bamboo slats (e.g. a plywood with a size 600x100mm we will cut in the way that the slats will be along the 600 mm dimension)
How long do I need to wait for my bamboo?
We start realization of an order immediately after receiving full prepayment. Rough-wood orders usually are realized in 3 working days.
Making plywoods for special orders prolongs realization time for a few days. Orders for oiled products we realize in 7-10 working days.
Will I receive VAT invoice?
Of course, always at the end of a commission, while shipping, we send an invoice via email.
