The deck I'm building is on a conctrete slab so the last row of decking around the front is going to be 2mm off the concrete making it more likely to get wet.
Is there anything special I can treat the bottom of that board with to make it last a bit longer?
Thanks
plane or rip the board down to get the gap to 8mm - 10mm off the slab this will solve the prob and let the water on the slab run out and not get banked up....

There is a product called Cutek it is an oil based timber preservative and the very best I have ever used.
I make outdoor furniture and since I have changed to the Cutek oils I have seen the improvement in my product over the last 2 years.
I had trouble for years with warping and discoloration, but now the product is fine.
It is 35% petroleum, and that is very important, as most oils such as Fest Watson and Cabots are vegetable oil based and grow mould after a period that will start dry rot and cracking.
I have tried all the major brands and Cutek is by far the best.A lot of the oils you are sold are in fact a paint, like Sikkens, and cover only the surface but a timber preservative like Cutek gets into the wood to stop moisture and that is were the problem comes from.
I have heard some very good comments about the Cutek brand of exterior timber oil and your words support the same. I was, however, under the impression that both Cabots and Feast Watson natural decking oil was based on 60% kerosine with the remainder of the product made up with various polymers and pigments. A check of Orica's material safety data sheet confirms this. Both are made with kerosine as the main product with no mention of vegetable oil. Both require turps for the clean up.I do agree totally that any deck coating product that is based on a natural organic oil like tung nut oil, lanolin and linseed oil will definitely lead to a black deck full of mould. There are a number of commercial products on the shelf for the un suspecting consumer.
