Decking from Massaranduba - laying, advantages + disadvantages

The Content Of The Article:

Choosing a Massaranduba decking is a choice for the highest quality and longevity. This precious wood gives each terrace a flair of solidity and perfection. Its dark reddish color makes it the most popular garden wood, when high quality is in the foreground.
What qualities does Massaranduba have?
Massaranduba is a hardwood, which is obtained from the balata tree. These trees grow only in Central and South America and their slow growth gives them a hard and fine-pored cell structure. Therefore, Massaranduba is one of the heaviest woods and is classified in the highest durability class 1. Due to this grown cell structure, no chemical wood preservation is required.
Precious woods are often criticized in connection with the deforestation of the tropical forests. The balata tree can not grow on plantations and is therefore a tree of the forest. Nevertheless, its impact is often controlled and sustainable. Therefore, buyers of massa varna wood should pay attention to the FSC seal, which refers to this controlled logging.
Massaranduba is extremely dimensionally stable. As a natural material, its drying process is associated with a significant loss. However, when this process is completed, there are fewer changes than, for example, Bangkirai. This great dimensional stability makes it possible to lay massa sand flooring in a composite, ie. H. from one floorboard row to the next by 50 percent offset joints. These butt joints can be open at the same time, ie with an air gap.
Despite this highest quality of wood Massaranduba is of equivalent quality cheaper than Bangkirai or Merbau.
Advantages and disadvantages at a glance:

  • Highest durability class 1 - therefore a purchase of duration
  • Uniform coloring of the wood - consistently noble design
  • No chemical wood protection - safe to use
  • Dimensional stability - universal design during installation
  • Cheaper than other precious woods
  • High wood density - therefore increased load capacity of the substructure must be considered
  • Prone to silvery discoloration - regular, annual oil application required
The laying of decking from Massaranduba
The heavy massa mandala wood places great demands on the substructure. With a plank thickness of 21mm, the maximum beam distance may only be 45cm. It increases with increasing thickness of the planks. The beams of the substructure may not consist of lower quality wood. For example, when spruce wood is used, movement of the deck covering in the event of heat or moisture changes would result in the screws tearing and resulting in unevenness.
Decking from Massaranduba are usually offered ribbed. Therefore, they should not be laid transversely to the direction of fall, because otherwise part of the rainwater would remain in these grooves and lead to pollution. In contrast, a longitudinal installation to the direction of slope supports a self-cleaning process of the coating.
The substructure must be firmly anchored. This means that it is bolted to the ground in the case of a concrete or tile substrate. For a terrace at ground level, the substructure is preferably mounted on leveled concrete slabs. In this case, a weed fleece should be placed under.
When laying the decking boards from Massaranduba, the distance between the planks must be between 5 and 8mm. This compensates the expansion processes of the wood. This uniform distance is made by interposed spacer blocks during assembly. The attachment can be facilitated by the planks are tightened when tightening with straps against each other.
Two stainless steel screws made of V2A are required per plank and attachment point. Any hardwood, and therefore Massaranduba, must be pre-drilled. Preferably, this is done by first the screw hole is pre-milled with a 90-degree countersink in the strength of the screw head. Only then is the actual hole corresponding to the screw thickness introduced with a twist drill. This order prevents the annoying fraying of the wood when sinking. The screw heads are flush with the wood surface. The length of the screws should be at least twice the plank thickness due to the high tensile forces.
The decking can be laid both evenly in full length and to beautify the design with offset open joints. Cutting the planks must be done with a carbide saw blade. Finally, the ends of the planks can be chamfered with an electric planer.
The installation at a glance:
  • Sufficiently strong substructure with short distances
  • Fixed anchoring of this substructure
  • Plank distance 5 to 8 millimeters
  • Use spacer blocks and straps
  • Per attachment point 2 screws made of stainless steel V2A in double length of planks
  • Lower and pre-drill screw holes
  • Equal laying or laying pattern with offset possible
  • Laying in the direction of fall
Wood protection and care
After completion of the installation, the deck covering receives triple protection by a special terrace oil. Depending on the climatic conditions, this wood preservation is repeated approximately annually.
Worth knowing & Tips
By nature, Massaranduba wood is not treated for the terrace and can be laid untreated. It contains a natural protection against rot, so no special treatment with paints or oils is required.
The natural color of the surface of Massaranduba wood for the terrace is pale yellow to pink gray. The heartwood, on the other hand, has a light red to violet-brown color. If you leave the wood completely untreated, it darkens to a reddish brown, which has a very harmonious effect.
As already mentioned, massaranduba wood is especially popular for the terrace because of its resistance. High-quality wood lasts up to 30 years, which quickly puts the high costs into perspective, as you have to expect a price of around 50 euros for a beam of two meters in length. The prices can vary very much, so it is highly recommended to make a price comparison.
You can buy the Massaranduba wood for the terrace in any well sorted hardware store and also in a timber trade you can find it. Furthermore, the Internet is also a source of shopping, especially because you can easily make the price comparison here.
Originally, the Massaranduba wood for the terrace comes from South America, where it is cut down in sustainably managed forests. However, this is not always the case, because the depletion is very widespread here.
Therefore, when buying Massaranduba and other hardwoods such as Bankirai / Bangkirai, make sure that the Massaranduba wood is certified for the terrace. With the certificate you can be sure that it comes from a controlled mining and was not robbed in the depletion.
