brings a sense of lightness to the overall aesthetics making it more diverse and modern. The high
lustre of the timber reflects natural and artificial light to produce a floor that appears to glow adding
to its modern appeal.

Kempas has a natural resistance to decay. The wood remains smooth under friction and is reported to have
no discernable odour. Kempas dries rather easily but can experience some splitting due to abnormalities in the
wood. Of note is the fact that Kempas is somewhat acidic in nature and can harbour corrosion in metals where
exposed when moist.
As a flooring option Kempas is a hard and durable wood. It is nearly identical in hardness to African padauk,
is roughly eighteen percent harder than hard maple, about one third harder than red oak, and approaches
eighty percent of santos mahogany's ranking of 2200.
Kempas contains pockets of hard deposits that can provide some difficulty when sawing and can promote
blunting of tools. Pre-boring is suggested yet the wood holds nails well once applied. Glue holds well with
Kempas flooring. This species sands well but does require some filling to ensure a good polish.
Kempas uses include flooring, chairs, railroad ties, shingles, cabinets, and veneer.
