Merbau decking over concrete slab

Re: Merbau Decking over concrete slab

Hi @Neo19 

They are just 140  x 19mm Merbau

So far no stain/oil

Most have that rich colour, but they do fade a little after the tannins leach out.

Will be coating with a wet look deck oil.

Cheers

Brendon

sorry @babakr , although that was the timber finish i've used what you see in the pic is just untreated deck after a wash. Glossy effect due to water on it :smile:

Re: Merbau Decking over concrete slab

Hi @Neo19 

Sounds great but I am wondering how it looks reddish while Merbau is brown. I actually wonder what timber can give me a reddish look (or what stain/oil). I found Kerri probably is a good choice for red/pink colouring but I looked at them in Bunnings and they look different from what I see in the finished deck projects.

Hi Mitchell,

I am at the end of joist installation on my veranda concrete floor for a 14 x 1.7 m deck. I haven't used brackets as the concrete was too uneven and I had to use window packers and sometimes other supports to level all joists across the floor. I screwed down the joists by 125 mm batten screws directly into the concrete using 10 mm wall plugs and it looks firm and strong. The next step is choosing deck boards which I am after a reddish look finish like what I saw in @Neo19 job. Here is the photos and appreciate any comments.

Re: Merbau Decking over concrete slab

Hi @babakr,

 

You'll find most decking timbers don't show their true colours until they receive a coating on them, so what you see on the shelf in stores might not reflect the final appearance. In the case of Neo19's deck, their decking boards have a vivid red due to the water which is sitting on them. Perhaps @Neo19 could update us on what the deck looks like with the Feast Watson oiled applied to it instead.

 

You might like to have a look at Jarrah as an option as it tends to have some dramatic red colours. Depending on your location Jarrah decking boards can be a special ordered item into our stores.

Re: Merbau Decking over concrete slab

Hi everyone,

I am in the process of choosing right decking screws. I searched in the building documents and everyone recommends 8-10 G/ 65 mm length (2 1/2") to fasten 90/19 mm decking boards (I am using Stringybark boards) but I saw in Bunnings (as well as other hardware stores) most screws being sold are 50 mm in length and it appears most people are using this range for common 90/19 mm decking boards. Can anyone please shed a light on this and what size (both diameter and length) is recommended for this application? Thank you in advance.

Re: Merbau Decking over concrete slab

@babakr sorry I haven't got any pictures of the deck soon after applying the oil. It's currently looking like it's time for another oiling with a little jaded and dusty at the moment. However from what I could remember it was reddish and closer to the wet look. I think I have applied 2 - 3 coats.

 

I have used 10g 50 mm square drive ss screws. I agree it's only been less than a year, however still feels solid.
