We are making a portable privacy screen out of a repurposed steel frame and framed pine lattice
I am wanting to learn about my options to finish the lattice to weatherproof it. The screen will be used under a covered patio area (sitting at the edge of the area) but will have some exposure to sun, rain, and wind.
I am considering painting it or keeping the natural timber look (although it is very rough and looks raw). What do I need to do for each option please? And would painting or staining provide most longivity for pine? Would appreciate recommendations for specific products.
Thank you ☺️
Welcome to the Bunnings Workshop community @carteblanche. It's wonderful to have you join us, and many thanks for your question about lattice screens.
You’re already starting with H3-treated timber that’s designed to withstand outdoor conditions, so it’s well-suited to sitting under your covered patio with some sun, rain, and wind exposure. The key now is whether you want to maintain that natural timber look or go for a painted finish.
If you want to keep the natural timber look, you can use an exterior timber oil or a combination stain-and-oil product. This will enhance the colour and grain while adding a layer of protection against moisture and UV damage. Keep in mind that with untreated rough surfaces, you may want to give it a light sanding first to remove splinters and make the finish more even. Timber oils will need reapplying every couple of years, especially in areas with more sun or occasional rain exposure.
If you prefer painting, you can use an exterior paint like Dulux Weathershield, which provides excellent protection and hides some of the roughness in the timber. Lightly sanding the lattice first will help the paint adhere and give a smoother appearance. Painted timber generally lasts longer between maintenance cycles compared to oils or stains, and it gives a crisp, clean finish that can brighten the space.
So in short, for longevity, paint will usually give the longest protection, while oils/stains give a more natural look but need periodic reapplication. Either option works on H3-treated pine, but sanding first is a good step for both finishes.
I actually did a similar project recently, where I chose to paint the framed lattice and was pleased with the results.
Please let me know if you have any questions.

Thank you Mitchell, I will go for the painted option. Do I need to use a primer?
And…for the metal frame…I want to paint it as well. It has existing paint (although it is quite worn and coming off). The rust I am using a wire brush on. What products would I use to paint it please? Could I use a metal primer and the Weathershield?
Provided the surface is sound, and you've removed any flaking paint and sanded back the rust, you can apply Weathershield directly over the top as it is self-priming @carteblanche. You might wish to treat any residual rust with a rust converter, as it will convert it into a stable, inert surface that can be painted over. You could use a primer suitable for metal, if you wish.
