It's that time again when my Kwila deck needs oiling.

I have previously only used true oil-based decking oil on it, but the brand I normally get seems to have switched to only water-based products for their decking "oil".

This is prompting me to wonder if oil-based is still the way to go.

What are everyone thoughts and experiences with oil vs water based decking oils, and what one would you recommend?

Am I even able to switch to water-based at this point?

Most stains are still oil themselves, they are just water-borne or solvent-borne (clever chemical engineering). However, unless previous applications have been degraded to the point where they are essentially no longer there, the answer to switching is almost certainly no. I've never spoken to anyone who recommended putting a water-borne stain over a solvent-borne one. You are likely better off speaking to the technical people from the product manufacturer though, and provide exact details about what you've used previously. Resene at least certainly offer this service.

I recall seeing a similar thread on this very recently. Have you looked at Drydens wood oil? I haven't seen it used on decks though.

Thanks for that.

Sounds like it'll be safer to stick with solvent-borne then. A lot if it is probably close to having none left, but the portions under furniture and that don't get sun still look as good as they did right after they were freshly oiled.

So, I guess it's a matter of deciding if the more expensive oils (Dryden, CD50 Extreme, etc) really offer enough of an improvement over the cheaper ones (Cabot, Wattyl, Valspar, etc) to warrant the extra price.

The expensive ones are well over twice the price, does anyone know if they last a lot longer than the cheaper ones? I.e. are they worth the extra money?
