Textrol, Osmo or other for treated softwood cladding ?

Fine Cheers

Just finishing covering my blockwork garden walls with horizontal timber cladding - standard treated rough 4 x 1 and 2 x 1 white deal on treated verticals. 4mm joints between timbers. The bulk of it is south facing and has lightened up nicely. However, we'd like to preserve the colour as it is now with a clear treatment. I have been using Protim on cut ends etc but does not have UV protection. From searching previous posts, it seems Textrol or Osmo are 2 options. Textrol cheaper at 39e per 2.5l with Osmo at 60e for 2.5l. Anything else out there ? Buy cheap, buy twice is a saying I am relating to more as I get older so willing to avoid the cheap other stuff on the market.
It might not be practical to do at this time of the year but I's like to have a plan in place.

Owatrol say that new wood should be treated with Seasonite in the first year as the wood weathers before Textrol is applied to the weathered wood.

I don't know whether that Seasonite step is really necessary with pressure treated timber but the waiting will probably produce a better result.

Thanks for reply. Called into a well known stockist of Textrol products yesterday who advised not to use Seasonite and go for Textrol. Clear out of stock at the moment but more to come in. Will see what the weather brings, would like to get done this side of Christmas ideally.

I normally buy Textrol online, but have to pay for delivery. Thats because local supplier wanted to charge me his delivery charge on top of the normal price. Just checked now and owatrol.ie seem to be out of stock of all sizes of Textrol. I'd be surprised if you can get 2.5l for €39.

I've used Seasonite on untreated and treated timber and it does seem to make a difference but not much. Plus after a few years I can't tell the difference between the wood that was treated with Seasonite first that that which wasn't.

I'm a fan of Textrol but never used Osmo but would love to hear from anyone that has.

Fine Cheers

Plus vat of course !!

Lot more expensive but if you can't get it anywhere else then try Amazon they have a couple of sellers with it in stock by the look of it and some Prime for free delivery.
