KAYU®-Sapphire is known for beauty and durability

KAYU®-Sapphire™ is a top choice with homeowners due to its natural warm beauty and renowned durability. Its dense cell structure and interlocking grain serve as a natural deterrent to decay, insects and molds. Its high quality and sturdiness is why it is often used in the construction of projects that require water-resistant woods like boat docks, bridges or watercraft ramps.

High density woods are more preferable to homeowners and builders these days. They are more reliable for their longevity, durability and relatively low-maintenance requirements.

Attention:  Learn About Natural Tannin’s in KAYU Sapphire

Natural tannin’s in KAYU Sapphire protect the wood but also seep when first exposed to excessive moisture.

KAYU Sapphire (Merbau) is one of the most durable rot resistant hardwood products, with a combination of an ultra-smooth surface and a natural warm beautiful color.

The species is known to possibly contain a heavy amount of the natural chemical of Tannin’s, which are found in most wood species.  Even though Tannin’s contribute to the specie’s many benefits; rot resistance, termite resistance, natural color and smooth texture, they may also seep when first exposed to excessive moisture, during the first month or two. 

Because of the possibility of seeping, we highly recommend added caution when installing KAYU Sapphire to a second story application or where there is the potential to stain surrounding areas, such as; patio, furniture, concrete, stucco, etc.  Thoroughly conditioning boards prior to installation; thus, exposing them to moisture until all signs of the red tannins have dissipated.  A small percentage of boards will seep, which will typically happen within the first few weeks; however, most will not.  The seep is non-toxic and can be pressure washed off the concrete.
