Can this treatment be painted over with water based paint?

Welcome to the Bunnings Workshop community @TimeMotion. Many thanks for your question, I'd be happy to assist.

I've searched for the product @Brad mentions and it appears that it's no longer available within stores. If you can allow me until Monday I'd be happy to call the manufacturer and find out whether you can special order the product and if it's indeed paintable. Alternatively, I have found TWA Woodcare 300g Ecoseal Tanalised Timber Treatment which is a spray-on product which can be painted over. The manufacturer specifies that the product will initially be green then fade to a green/brown over a  few weeks. The product can be painted over when dry with water-based paint or primer.

Please let me know if you have additional questions or need further assistance.

Long time follower, first time poster... I was wondering about the substitute for the discontinued preservative asked by OP. I am in a similar situation and would want to stain and not paint over the timber.

Welcome to the Bunnings Workshop community @arian10daddy. Many thanks for your question, I'd be happy to assist.

It's fantastic to have you join us and great to see you jump straight into the discussion. There is a clear H3 aerosol timber preserver, which can be stained over, that can be special ordered into stores. The product is called Koppers End Seal by RLA and its part number is 999704. The special order can be placed in-store or over the phone.

Please let me know if I can assist you with placing an order or if you had any other questions.

Thanks for the prompt response.

Would there be a H4 alternative as well, say for sealing the cut ends for timber retaining wall that can be stained? 

[MitchellMc]

Hi @arian10daddy,

I am unable to locate a clear sealer which is rated higher than H3. I'll pass this onto our merchandise team to look into further. What type of treated pine sleepers will you be using for the retaining wall? The majority of our sleepers are green in colour already. As mentioned earlier Ecoseal H5 treatment is green, to begin with, and will then fade to a green/brown over the next few weeks.

Hi Mitchel,

I'm considering 200x75 H4 treated 1.2m sleepers for posts as well as the wall, with a Merbau/Jarrah colored stain finish. Not all posts will be 1.2m (or its multiple) apart, so I will have to make cuts to the sleepers. Also, I'm fine with sealing the bottom end of the posts with the black colored bitumen stuff available at Bunnings, but I can't do that to the top part and the ends of Sleepers, and these will have soil contact. Hence, the queries.

Nevertheless, great work, being on top of the things! Cheers!
