About Dansson Hardwood

Pacific Kwila Decking

Pacific Kwila (Merbau) is a hardwood ideally suited to the manufacture of outdoor decking. Not only does it have a beautiful grain and appearance, it is regarded as one of the world's most durable timbers.


An abundance of natural oil in the wood ensures your outdoor setting looks good, is easy to maintain, and lasts for many years . . . in all conditions!

Pacific Kwila Decking Frequently Asked Questions



Q. How does Pacific Kwila (Kwila) compare to standard pressure treated (ACQ) decking?


A. Pacific Kwila is almost double the hardness (1925 vs. 690 on the Janka Scale) of Yellow Pine. Pacific Kwila is naturally insect/termite resistant, is not prone to splinter and check(split) as it ages, and is highly resistant to decay when fully exposed to weather if clear of ground and has good air circulation.

In other words, Pacific Kwila:

  • Is more than double the hardness of standard pressure treated pine

  • Is not affected by termites or insects

  • Does not typically splinter due to its natural grain texture

  • Doesn't decay if given a minimal amount of air circulation

  • Does not require regular sealing to protect it

Q. How does the cost compare to standard ACQ pressure treated pine decking?


A. Typically, Pacific Kwila decking will cost about 200 - 300% more up front (for decking material only – not the total deck cost) and has an average life of 25 – 50 years. However, this does not take into consideration the cost for cleaners, sealants and regular maintenance required for pressure treated products which have an average life of about 8 -12 years AND the cost to replace the ACQ deck 1-3 times over the average life of a Pacific Kwila deck. When looking at the total cost of ownership, appearance, home value increase and general enjoyment – Pacific Kwila is a great product and a great deal!

Q. Does Pacific Kwila decking have any special installation requirements?


A. There are 2 key requirements:

  1. It is very important to provide at least a 3/32 spacing between boards to allow good air circulation. Since Pacific Kwila is 50% stronger than Oak, standard 16” OC joist spacing can be used with perpendicular or diagonal decking layouts. The shrinkage rate is less than 3% so spacing during installation is critical to insure typical lifespan of 25 – 50 years. Pacific Kwila does not shrink!
  2. Pre-drilling for fasteners is required within 6 - 12 inches of the board’s end to prevent splitting due to the dense nature of Pacific Kwila.

Q. I was told Pacific Kwila “bleeds or weeps” initially. How long does this last?


A. Pacific Kwila contains more oil or tannin in its pores than most other exotic hardwoods. When first exposed to moisture this surface oil/tannin will bleed or weep. The time period for this process to complete varies with timber, temperature and humidity. Generally, a good overnight rain will remove most of the oil but the actual time required varies. The oil/tannin is not sticky but can stain (looks similar to weak coffee) so it is important to cover or protect anything that could be stained below the deck during this initial period. Once complete, Pacific Kwila will not bleed again. A short inconvenience for 25-50 years of great service from your new deck!

Q. Where does Pacific Kwila grow?


A. It grows primarily in Indonesia, Malaysia, Papua New Guinea and Northern Australia. Each country has harvesting guidelines that are in place to prevent over harvesting and insure continued supply in accordance to the International Timber Treaty Organization (ITTO) guidelines.

Q. Where is Pacific Kwila typically used?


A. Pacific Kwila decking is very popular in Australia and New Zealand. The harsh coastal environment requires an extremely durable material and Pacific Kwila is a natural wood that has been used for docks and decking for centuries.

Q. Are there any special fastener requirements?


A. Pacific Kwila accepts a variety of fasteners: however, a trim head screw design will offer the best appearance and place the least stress on the material. Several fastening systems are also available that do not utilize any surface fastener exposure. Utilizing the recommended fasteners will eliminate the need for pre-drilling except on the ends (see previously mentioned installation requirements). Dansson recommended fasteners are:

1) GRK trim head screws in Climatek or stainless steel for standard fasteners. (#8 x 2” for decking)
2) Spot Nails’ Tebo System for a “no exposed fasteners” look.

Q. What kind of rail system should I use?


A. There are many different styles available in addition to a standard railing from glass, stainless steel cables, coated steel, coated aluminum, etc. Top and bottom rails are available in Pacific Kwila as well. Many decks will utilize the uprights placed in the ground and extend them above the deck to create corner posts and structural support for the railing system. These are generally stained to match the deck.

Q. Does Pacific Kwila require a sealant be applied to all cut edges like many other exotic timbers?


A. No, the natural oils in Pacific Kwila protect it from checking/splitting which makes installation faster and easier.

Q. I have just finished installing my new Pacific Kwila deck. What should I do to protect it?


A. First, let the Pacific Kwila bleed as discussed above. Then it can be left alone, stained, painted or oiled to get the appearance desired. If nothing is done, the decking will turn a silvery gray after several months. Pacific Kwila accepts stains and paints formulated for exterior hardwood/exotic wood well. Always test on a small area first to insure good results. The easiest treatment to apply is oil which does not require stripping with reapplications. Simply spray, brush or roll on the oil when the color starts to fade and the oil brings back the rich natural color of the Pacific Kwila. Dansson recommends: Cabot Australian Timber Oil in either Natural or Pacific Kwila color.

Q. I have not done anything to my deck for several years and it has turned completely gray Can I return it to its original color?


A. Yes, Pacific Kwila can be returned to its original color by sanding or power-washing to remove the top surface gray Care should be used when power washing to prevent “burning” the wood by getting too close or using excessive high pressure. Once the wood has been cleaned it should be allowed to dry thoroughly. Then coat with oil or apply desired finish. A second coating may be required.

Q. What sizes are available?


A. Decking is available in ¾” x 3 ½” in random lengths from 6’ -19’. Railing pieces are available in 1 ½” x 3 ½ “ x 8’ (bottom rail) and 1” x 5 ½” x 8’ (top rail). Custom sizes are available by special order.

Q. The decking has a smooth and reeded side. Which should I use as my top surface?


A. Either side is acceptable and it depends purely on the appearance desired. The reeded or grooved side offers a distinct appearance not found on most other decking materials that many builders and customers prefer. The grooves are not deep enough to make cleaning difficult and if exposed to direct sun, the reeded side does not transfer the heat due like a flat surface. In other words, it doesn't feel as hot when walking barefooted!

Q. How do I clean my Pacific Kwila deck?


A. Simply hosing it off, sweeping with a broom or using a power blower are the most common and easiest. Power washing should only be used if restoring a deck.

Q. Can I place large flower pots on the deck?


A. Yes, Pacific Kwila is extremely strong and even the largest pots will not present a problem assuming the general design of the deck will support the load. Note that Pacific Kwila does need to get airflow and large pots should be placed on casters or gliders to allow a slight gap (3/32” minimum).
