I have to "treat" a large decking area so it looks better than it does now. It is in good condition with no apparent problems .. just needs waking up .. so to speak. Likewise the garden lap panel fences.
What should I be looking for on the decking before I treat and how is it best to put on any applications.
Looking at some seb sites, power washing is reccomended first.
Any info would be gratefully received.
