WARNING:
This product is unsuitable for neophytes; like burls, Swirls are veneers with a lot of counter-grain and, therefore, can be warped; you must manage any cracks or open defects.
Like all burls, it is necessary to flatten the veneers, fill in some tiny black knots that pierce, or use the cookie-cutter technique for bigger knots.
What are burl and cluster veneers?
Burl and cluster veneers are rare and reserved for prestigious projects.
Burl veneer is composed of grouped pinknots, which are densely packed and usually cover a good portion of the veneer sheet.
Cluster veneer, on the other hand, is characterized by the wild movement of its wood grain. However, clusters can also have pin-knots, either isolated or in clusters.
Numerous pin knots mean some pin knots are piercing, and open cracks are considered a natural part of this type of wood.
After gluing, you can fill the small holes with wood putty to complete the finish. Alternatively, before gluing, cut out the larger holes with a cookie cutter and insert a veneer disc of the same size, taken from a scrap.
By nature, burl or cluster veneer has a lot of counter-grain, so its sheets are often warped. Even when pressed, they may still be slightly warped.
However, it is necessary to differentiate between the two types of waving:
Hard waving makes a "pop" sound when you press on them with your finger.
In this case, it's advisable to flatten the veneers before using them. There are several methods; please inquire.
Soft waving doesn't make any noise.
In this case, there is no major problem; however, if you want to join multiple sheets, it's better to press them together beforehand.
What is Mappa Wood?
Mappa is a commercial name for poplar or cottonwood.
What are the common Names for poplar?
Poplar (UK), cottonwood(US), poplar covers more than 30 different species, such as European aspen, grey poplar, Italian poplar...
What is the botanical name for poplar Wood?
Populus nigra (black poplar).
Its botanical name refers to the color of its bark, not the color of its wood.
Where can we find poplar in nature?
Northern Europe.
Numerous poplar hybrids are found on all temperate continents.
How to Recognize Poplar Wood?
Poplar is a soft, lightweight wood.
Its wood is white with a colored heartwood, veined with pink and light yellow.
What are the mechanical properties of poplar Wood?
Weight: approximately 385 kg/m³ at 10-12% moisture content
Janka hardness: 2020 Newton. For comparison, ash is 6580 N, and grey poplar is 1650 N
Elasticity: 7.21 Gigapascals. For comparison, US maple is 12.62 GPa, and grey poplar is 9.75 GPa.
Tensile strength: 36 Megapascals. For comparison, US maple is 109 MPa, and grey poplar is 62 MPa.
What are the uses of poplar veneers?
Poplar is generally rotary-cut and used to produce plywood and food packaging crates/boxes.
Poplar is a plantation wood, easily recognized by its rows.
One of Poplar's hybrids, European Aspen, is sliced (not rotary-cut) and used in decoration and furniture as a substitute for cherry.
In burl form, it is mainly used for decoration and the manufacture of high-end furniture. This burl became a classic in Russia and Germany between the 17th and 19th centuries. In France, the golden age of Mappa Burl was in the 1960s and 1970s for high-end furniture.
What are Wood Veneers?
Veneers are thin sheets of wood obtained by slicing or peeling.
Their surface appears to be planed wood, without any finish or treatment. They are neither glued nor backed with any other material. This means that both faces of the sheets can be used.
Wood Veneers are mainly used to cover less aesthetic substrates, such as plywood or particleboard, to make furniture or wall panels.
Veneers are also used to create decorative objects such as lamps, jewelry, bookmarks, and more.
By assembling several sheets of veneer on top of each other, it is possible to manufacture objects requiring high mechanical resistance, such as skis, bicycle frames, or musical instruments.
The applications of veneer are as varied as they are multiple.
Since veneers are made of genuine wood, all wood finishing products, such as varnish, stain, or oil, are suitable. The choice of finish will depend on your personal preferences and the object's intended use.
The veneer offered here is a sliced sheet of uniform thickness, but the thickness may vary from one species to another. The standard thickness is around 0.6 mm.
Although the edges of the veneers have been cut roughly straight, they are not perfectly parallel to one another. Some veneers may retain the natural taper of the tree, being slightly wider at the foot than at the top.
Some veneers may have slightly wavy edges (following the tree's natural shape) on the sides. In this case, the indicated dimensions correspond to the minimum veneer width specified in the "Dimensions" section.
How to use veneers?
How to cut the veneers?
Veneers can be easily cut with a utility knife.
For straight cuts, the best results are obtained with a veneer saw.
Use a fretsaw, scalpel, or veneer knife for curved cuts.
Always allow for a slightly larger veneer sheet than your intended surface. This will allow you to adjust the size after gluing for a clean finish.
A flush trimmer can also be used to trim the veneer after it has been glued.
When cutting with a utility knife or veneer knife, it is best to cut with the grain of the wood. To check this, run your finger along the edge of the sheet. The direction that feels smoothest is the ideal direction for cutting.
What is veneer splicing?
Since veneers come in the width that nature gave us, you may need to cover an area wider than the available veneers.
Therefore, you need to splice the veneers by gluing or taping them side by side to achieve the desired width.
Trim the veneer's edges with a straight, smooth cut to achieve a good joint.
Stick the veneers in place with tape (the blue one is a good choice).
Usually, the veneers are spliced side by side, but to obtain a longer length, they can be spliced foot versus foot.
The splicing must be done before gluing the veneers on the substrate.
What Glue to Use for Veneering?
Several types of gluing are possible.
Vinylic glue (PVA or PVB) is well-suited for porous substrates such as plywood, particleboard, or MDF. The veneers must be pressed with clamps over the entire surface at once.
Note: A technique using vinylic glue and an iron can also be used to glue veneers, but we strongly recommend using this technique only if other gluing solutions are not possible.
- Neoprene glue is applied to all surfaces, especially non-porous surfaces, using two coats of glue and marouflage.
- Animal glue, such as hide, sinew, or bone glue, is a product that must be cooked in a double boiler and used hot.
How to Sand Veneers?
Veneers and all our products are genuine wood and can be sanded accordingly to the thickness.
Please do not use a belt sander, regardless of the veneer's thickness, as it could pierce the veneer.
With a 0.6 mm veneer, lightly sand with 120-grit and then finish with 180 or 240-grit. With an orbital sander, 180-grit is already sufficient for most applications.
How to Finish a Veneer Realization?
All finishing products generally used for wood are suitable for finishing our products. For example, you can use a varnish, wax, paint, or oil.
However, ensure that the product you want to use is compatible with the final use of your creation.
