Muiracatiara hardwood is widely used because of its decorative appearance and typical hardwood properties (durable and strong). You will often see this hardwood in horizontal railings, facades, bridge decks and sheet piling. When planed, it becomes very slippery and has a greasy feeling.
Fresh 1200-1250 kg/m3. At 12% moisture conten 750-900 kg/m3.
Red with black stripes. This type of wood is therefore called Tigerwood.
The colour of the heartwood is light orange-brown, with a variable proportion of dark brown 'veins'. This makes Muiracatiara wood particularly decorative. After exposure to sunlight, the wood quickly turns to an orange-reddish brown to deep red brown. The sapwood is easily distinguishable as it has a straight wire with few irregularities. The grain is fine.
Straight to cross-thread, sometimes slightly wavy.
Fine to moderately coarse.
Natural drying in the open air can be done without any problems. Accelerated drying of Tigerwood can lead to surface cracks.
The Muiracatiara FSC wood is easy to work with, despite the high density. Gluing is reasonable easy and we have good experiences with finishing. Pre-drilling is recommended. The wood dries fairly quickly, but this process must be done carefully to avoid surface cracks in thin wood and longitudinal cracks in thicker wood.
Good. Pre-drilling is necessary.
Finishing of surface
Good with lacquer and varnish. After sanding, finishing and/or lacquering, it can show its beautiful pattern.
