Appearance, surface, and effect in outdoor areas

The appearance of Cumaru decking boards is warm, striking, and natural. A Cumaru deck appears less dark than Ipe, but bolder and more expressive than many lighter decking woods. The wood pairs well with natural stone, plastered facades, modern gardens, and classic outdoor areas.

Smooth Cumaru boards have a calmer look and are generally easier to clean. Ribbed, grooved, or French profiles offer a stronger linear pattern and a textured surface. Which design is more suitable depends on the desired look, usage, cleaning requirements, and installation situation.

Installation, substructure, and accessories

For a robust Cumaru deck construction, professional assembly is crucial. The boards should be laid on a suitable substructure. Sufficient rear ventilation, appropriate gap spacing, constructive wood protection, and clean water drainage are important.

Since Cumaru is a very hard hardwood, care should be taken during installation. Pre-drilling is recommended. Suitable stainless steel screws and appropriate installation accessories should be used for fastening.

Care and natural graying

Like all wood used outdoors, Cumaru also changes color due to sun, rain, and weather. Without regular maintenance, a silver-gray patina will develop over time. This graying is a natural process and does not affect the technical function of the deck.

Those who wish to maintain the warm brown tone of the Cumaru decking boards longer should clean the surface regularly and treat it with a suitable care oil. This helps the reddish-brown wood look remain visible for longer.

Tip: Crucial for a well-maintained wooden deck are not just care products, but also constructive wood protection. This includes slope, ventilation, water drainage, and a suitable substructure.

Origin of Cumaru

Cumaru comes from South America. This dense hardwood is used for decking and other outdoor areas due to its high natural durability, strength, and striking color.
