More beautiful materials are being used to make bathroom furniture all the time, and even the most demanding customers will find a surface finish and colour to their taste. That’s why checking whether the furniture is truly moisture-proof is often the last thing on our minds. But that should always be your starting point if you want the furniture to last – and to keep looking beautiful – for a good many years to come.
Be they melamine, solid timber or metal varnish, the choice of colours and patterns is almost endless. The materials also cope quite effectively with water droplets. As such, if water sprays from your sink or even from your tub (bathrooms often being rather compact places) onto the furniture, this is unlikely to cause any problems. This is because modern paints and resins are not only moisture-proof, but also ward off mould.
But things are very different when it comes to the edges of furniture boards and the joins in them: these points in particular (the edges of doors, the joins in insulation boards and the space around kitchen sinks) are at the greatest risk of moisture getting into them. And how well they cope with moisture varies enormously between boards. For example, MDF (medium-density fibreboard, hot-pressed with steam as part of a dry process) is widely used in the construction industry but soon starts to swell if moisture gets into it. This process is exponential, because the more a board swells, the more moisture it absorbs.
For this reason, we recommend asking the sales person for a certificate showing what kind of boards a piece of furniture is made from and what technology the manufacturer uses to make the joins and edges of the furniture boards moisture-proof. The most effective technology in this regard is PUR edge-banding. This is what we use at Aunman. All parts are banded using PUR adhesive, becoming completely heat- and moisture-proof as a result. It is also important to make sure that surrounding furniture parts are edge-banded as well, including invisible edges and joins. If a manufacturer utilises high-quality banding but leaves invisible joins and edges unbanded, the technology will be of little use in ensuring that the furniture is moisture-proof.
Before adopting the technology, Aunman ran a test in which a furniture board whose every edge was banded using PUR technology was held underwater in an aquarium for a week. The board emerged entirely moisture-free.
