Sorry, but this is yet another "which preservative should I use" question. I have searched the forums, but most questions of this kind seem to focus on maintaining the colour/aesthetic qualities of decking etc., or at least balancing that consideration with out and out preservation by using combination of oils/preserver.
My raised bed is quite large (about 7m x 1m x 0.5m) and is made from a pressure treated, polythene lined carcass with cladding made of standard decking timber (not sure what kind of factory treatment it underwent, but it does have a slight greenish tinge so I guess it has something).
Right after the bed was constructed we had what seemed like a whole month of rain and xmas etc. got in the way of me even trying to organise getting it treated, so it has already had a thorough soaking.
The weather's been dry and windy for over a week now though so I'm hoping to get it done this weekend. I suppose then that my questions are as follows:
1) Should I wait until a proper warm springtime dry spell before I do this, or am I better to get the preservative on there as soon as possible? It seems dry but I don't really have a clue when it comes to exterior wood.
2) What should I use? I'm not hugely concerned about appearance. I don't mind the "grey wood" look and just want it to last as long as possible. Shops-wise, I'm pretty much restricted to the sheds, although we do have a Johnstones/Leyland locally that I can get to. I have an HVLP spray gun, but would prefer brushing unless I'm likely to get better results with the sprayer.
Thanks for reading - any help you can give is very much appreciated!
