Three reasons why Marunaka's flooring is reputed to not have gaps.

Once it is dried, it will be in a dry state! Since it is dried at low temperatures, it dries cleanly to the core while "retaining the oil content."

Wood that has been naturally dried to a moisture content of about 15-18% or artificially dried wood that has only been reduced to about 13% will shrink significantly when dried to a moisture content of 8%. Therefore, it is important to "teach the wood" to remember the over-dried state once. In our drying process, instead of rapidly drying at medium to high temperatures of 60-120°C, we use a method that slowly dries the wood at low temperatures of 40-50°C, where the moisture inside the material begins to escape. If we raise the temperature to medium or high ranges to speed up the drying process, the oil in the wood will evaporate along with the moisture, leading to cracks (especially internal cracks). [Three Reasons] ■ Once in an over-dried state, the board "remembers the drying" at that time. ■ Eliminates "moisture unevenness" in the board, allowing it to withstand sudden changes in humidity. ■ Dried at low temperatures, leaving "oil content intact," resulting in a clean dry to the core of the wood. *For more details, please refer to the PDF document or feel free to contact us.
