Decking Oil is a product that will keep your deck in good condition, its easy to apply, do not put too much on at a time allow to penetrate, better to apply a thin coat then a second later.
I have found that a product called Deck restorer makes the deck slippery.
Of course decking stain is a great way of colouring your area, but I always say this, please make sure that you will like the colour because it is a stain and will need to be worn over a period of time. There are ways of getting the stain off but that invloves more cost.
In my mind natural effect is better, so oil or a product called Stay New is good.
See you all soon!!
