How to specify

Product: Timber will be Porta Cumaru (Dipteryx odorata). Technical Features: FSC® certified, near-zero tannin bleed, with a density of 1,085 Kg/m3, certified Class 1 durability to AS 5604 natural durability above ground and resistant to Australian termites, min. Janka hardness of 14.8kN, a seasoned structural rating of F34 (beams) and bearer and joist width must not be less than 45mm, MOE of 22GPa, MOR of 175MPa, or unseasoned rating of F27 (posts). Where unseasoned Porta Cumaru timber is used, appropriate construction procedures must be adopted to compensate for the shrinkage. Porta Cumaru timber supplied for structural purposes such as posts, bearers and/or joists shall comply to AS 2082 and deck boards timber shall comply with AS 2796. Porta Cumaru timber should be pre-finished in the factory and a quality coating applied on all sides. Cut edges should be end sealed.

Certification: Porta will provide a compliance guarantee with all orders indicating the Porta Cumaru timber has FSC® certification.

Maintenance and Care:

Like all timbers, care and attention when installing Porta Cumaru will further enhance durability and ease of maintenance:

When specifying Porta Cumaru request pre-oiling. This ensures all sides are evenly coated with a high-quality coating, reducing time and cost on site. Porta recommends clear oil Cutek CD50® or equivalent.

Coat all end-grains and any on-site protrusions with an appropriate impermeable end grain sealer. Porta recommends Teknos Teknoseal 4000 or equivalent. This minimises end cracking by sealing the end grain from moisture and ensuring the long-term beauty of Porta Cumaru. Click below to download a flyer with more information. 

A maintenance schedule is necessary to ensure the timber retains its beautiful appearance. Unprotected timber will discolour when exposed to UV radiation. To retain the timber’s natural colour regularly apply pigmented coatings to protect the timber from UV and moisture as per manufacturers’ recommendations. Call Porta for more information on coating recommendations.

Should a silver-grey look be desired, regularly apply a clear unpigmented coating to protect the timber from moisture as per the manufacturers’ recommendation.

For more details see the Porta Installation Guide, or,
