    KAYU ® –Legendary Performance

KAYU Mahogany  Primed Trimboards™ hardwood should be your first choice for Outdoor trim; used by Interior Designers, Architects, Builders and Homeowners.  It is among one of the high quality products imported by KAYU ® International from SE Asia. KAYU Mahogany  Primed Trimboards™ is a proven performer for over 100 years, well known in the yachting realm; here in the US market and all over the world.

As tough as they are beautiful

Aside from KAYU Mahogany  Primed Trimboards™ being one of homeowners’ favorite species because of its natural warm feel and paint holding characteristics, it is an incredibly strong and stable wood. Its dense cell structure and spiral grain serve as a natural deterrent to insects, decay, and molds. Its quality is tried and tested over time and its sturdiness is of no doubt why it is often used in the construction of projects that require water-resistant woods like sail boats (i.e. Cris-Craft boats), boat docks, bridges or watercraft ramps.

Woods of high density are more preferable to homeowners and builders these days.  They are more reliable for their longevity, durability and relatively low-maintenance requirements.  Incidents of weather and pest damages are unusual when properly maintained; one of KAYU Mahogany  Primed Trimboards™ strongest attributes is being able to withstand these conditions.


The finger joint is by far the most commonly used joint to form long pieces of lumber from shorter solid boards. This is made by machining a set of identical cuts in two pieces of wood, then gluing them together. The strength of a finger joint comes from the long-grain to long-grain contact between the fingers. The number of contact points provides a solid gluing surface. KAYU International only uses high quality water-proof, type 1glue. The addition of some edge glued pieces further adds stability.

Our KAYU Mahogany  Primed Trimboards™ are ‘Square’ edge corners.  The edges/ends of the trim meet up with each other so there is no round edges; providing a uniform surface between the boards and allowing for a corner board application with a clean transition between the individual boards.

Unlike soft Cedar woods, the high density of our Trimboards is extremely stable and known to be one of the most durable, dent  and surface checking resistant hardwoods available with excellent paint holding fiber.

A few basics to consider, while selecting exterior trimboards

  • Water Resistance. Water-resistant types of trim will have longer life spans.
  • Versatility. Make sure the trim has the versatility to meet the varied needed of your specific project.  If there are aspects of your home’s exterior that will make using a particular type of trim more challenging than others, make sure you understand what the added costs or necessary adjustments will be.
  • Aesthetics. Your trim will be in full view as you come and go, so make sure it is beautiful and pleasing to you.
  • Durability. Does it have the strength to resist temperature shifts in your climate? How does the species stand up to everyday wear and tear.
