Hi Paul,
Thank you for the enquiry.
For best results we advise applying the Roxil Coloured Wood Preserver first. The treated wood should then be suitable for overcoating with the Roxil Wood Protection Liquid within 24 hours.
I hope this helps, if you have any further queries please feel free to get in touch on 01403 210204.
I'm building a fence 17m long and 1.8m high out of Larch. Once completed I want to colour it and protect it. I really want to give it a level of protection that will last for the next 10 years, and due to the intricacy of the construction I want to apply the colour and protection by spraying it. Can I use a combination of your Coloured Wood Preserver and your Wood Protection Liquid?
