Timber Cladding

[Mr Chibs]

Not the battens, the cladding was overlapped, similar to the op‘s image.

Oh ok I get you, I guess it wouldn’t be 44mm though as that would assume no overlap with feather edge boards. Probably more like 30-35mm depending on size of overlap but still heafty battens.

 

[Mr Chibs]

FWIW mine was just planks, not feather edged. The planks are fairly heavy and with a fair few on the wall 15/16 tall, and they are wide 250mm.

Cedral like all cladding, should have a ventilated air cavity behind it.

Correct. All the vented trims etc are usually stocked by the suppliers. Finding a stockist is the hard part.

 

[bluebaron]

Bit would 25mm battens be enough?

Haven't used Cedral, but have used cembrit weatherboard plank https://www.cembrit.co.uk/cladding-panels/wood-look/plank which is available in a range of colours. My local merchant (cwberry leyland) stocks a good few colours and has trims to match. It's easy to put up and very DIYable provided you buy or hire a guillotine and gecko gauges. The manufacturers provide very detailed installation guides. For cutting odd angles etc, I find a wet tile cutter works quite well. It has a tendency to very quickly blunt saw blades.

You can nail it, but cembrit supply special screws which are recommended. Merchant told me their cembrit rep said there had been a big problem on a local estate where nails had worked out over time through thermal movement. The screws are self-drilling but I find it is quicker and easier to push a 3mm pilot in first rather than spinning the screw until it bites. https://www.cwberry.com/Building-Ma.../Cembrit-Zytex-Screws-for-Timber_02252811.htm

Thanks but still doesn’t answer the question about batten size?

 

[mrrusty]

Use the batten size that gives you the ventilation gap suggested by the manufacturers installation guides. Cembrit show minimum 20mm. I have used 25mm slate battens successfully with screw fixings https://www.cembrit.com/downloads/installation-manuals/

Thanks rusty,

Cedral say 30mm I’ll have a look at cembrit.

Just use 25mm. 30mm is nonsense.

 

[bluebaron]

Yep ill do that

Just use 25mm. 30mm is nonsense.

thanks

I'd recommend a few spots of mastic on the overlaps to stop it rattling in the wind when installing it.

Agree, good brushing down with a stiff bristled brush (e.g. https://www.toolstation.com/stiff-general-purpose-brush/p97606 and/or https://www.toolstation.com/industrial-stiff-yard-broom-with-handle/p29500). Make sure any bare timber is back to solid wood.

The treatment - ideally ought to be proper 'Creosote', very difficult to find nowadays or a mix of creosote and Bitchumastic. You need a liquid to soak into the timber. Modern wood preservatives just don't last as long.

Good Morning,
After 2 years, I finally have decided to repairing it and have been painting the wood with Creocote (It is not as good as creosote, but hopefully it can still do some prevention). I now struggle with top paint, and was hoping if I could get some advise.

I asked around my neighbours, some people said use ducksback fence paint, some said use bitumen paint, but the timber store staff said use bedec barn paint, then the farmer suggest I should use oil based paint. I am now very confused and don't know which to go for. I just want it durable, able to withstand sunlight well and black colour. Any recommendations will be greatly appreciated ‍
