Description

Garapa is probably the most popular hardwood decking originating from South American. In its natural form it is light orange/brown in colour. It is very durable and an excellent exterior decking. Garapa weighs approximately 900 kilograms per cube. It is very stable and shows little to no movement after installation.

It is one of 5 decking species we stock. Our other decking species are Balau, Massaranduba, Red Grandis and Pine.

Installation

The recommended span for 19mm Garapa decking is 450mm and 550mm for 21mm. A 4mm gap between boards is recommended.

It is critical that the supporting structure is correctly designed. A poor quality deck is often the result of a poorly or under designed supporting structure.

Fastening

We stock top quality Stainless Steel decking screws. A 4mm drill bit is recommended for pre drilling. A 60mm length is recommended but 50mm can be used as well. A specialist countersinking bit is recommended – it is difficult to countersink correctly with an ordinary drill bit.

Galvanised steel posi screws are NOT recommended due to their relatively short life span. It is not worth the trouble of using cheap screws (e.g. ordinary chipboard screw – stainless or galvanised) on a relatively expensive product.

We stock the Easyclip system for hidden deck fastening. As Garapa is very stable, decking clips are a good alternative to normal screwing. A biscuit cutter is used to form the groove for the clip on each side of the deck. More info on this system can be viewed at www.easyclip.co.za . It is critical that the installation instructions are followed for hidden deck systems !

Finishing

Garapa can be left untreated and it will slowly age to a distinctive greyish-silver with fine cracks. To retain the rich dark red, it can be oiled or stained using our Galseal deck oil. Various colours are available. This can be reapplied as necessary – a 2nd coat probably after 6 months and then yearly depending on sun exposure.

The use of surface sealers and varnishes is not recommended as this causes the timber to heat up excessively in hot conditions and does not allow the timber to breathe.

Following correct installation and periodic maintenance, this decking should provide a very long lasting and beautiful deck.

If no oil is applied, Garapa will fade to a grey colour but will show very fine cracks as it dries.

Following correct installation and periodic maintenance, Balau should provide a very long lasting, beautiful surface.
