Cumaru hardwood decking: Maintenance.

It is recommended to apply WOCA natural color oil or WOCA pigmented oil once a year to preserve and enhance the natural color of CUMARU wood. Also, oiled boards are less likely to crack.

Installation.

It is recommended to double the lags at the front and back of the structure (10 – 20cm second lag from the first), and the following gaps between the lags are 35 – 40 cm to control the curling of the ends of the boards. Doubling the lags is also mandatory at the connection lines of the boards. For fastening, you can use A4 direct fasteners through the top of the board, invisible stainless steel invisible fasteners such as CAMO or Fastshifter, and special invisible fastening from below. The recommended gap between the boards is 7 mm ( a spacer is used).

It is recommended to pre-drill screw holes to prevent splitting and cracking. Use only stainless steel screws or fasteners . Avoid contact with corrosive metal objects, which can cause difficult-to-remove blue-black stains on the wood.

Fasteners recommended by MDS experts:

Concealed fastening to a wooden frame

Hidden fixing latch – universal (for wooden, hardwood, thermo or aluminum frames)

Expandet a4 4.8×75 – directly over the top of the board

Recommended.

Leave gaps between the boards (about 7 mm) to ensure proper ventilation and natural movement of the wood.
Use concealed fastening with stainless steel screws.
It is advisable to acclimatize the boards to outdoor conditions before installation.
If overhead bolting systems are used, it is important to use high-quality, corrosion-resistant bolts.
