I've inherited a garden bench - cast iron sides and wooden slats.

So far I have pulled it apart. Plan to repaint iron and install new wooden slats.

Am I ok to just scrub and sand back the iron and then use a spray paint to finish?

Slats are approximately 100 x 42 x 19. Would treated pine do the job, with vanish/oil finish?

Can’t see why not but I’d be tempted to use a primer before my top coat for extra durability and I’d be tempted to use a hardwood slat rather than treated pine if you can access it.

I agree with Potts on both using primer and hardwood. Treated pine will not look great with varnish or oil. Hard wood decking would be a good cost effective way to get the slats.

Thanks.

Looks like hardwood decking the way to go. Available in the right dimensions so will save cutting.

Is there a cost effective option for primer & paint? The cast iron ends are relatively small surface area.

Would primer spray and paint spray work? Usually use brush paint but spray seems quicker and decent finish.

I did a similar one a about 10 years ago. Killrust black on the ironwork, merbau wood and decking oil. It's been in the weather ever since and is still in good nick.

i think i would use automotive primer/paint/clear for the metal parts, repco and autobarn seem to have a good selection of rattle cans. supercheap auto not so much, not sure why

I did this one a while ago, using Karri decking boards from the big green shed, finished with Organoil outdoor furniture oil. I bought 130mm wide boards, then ripped them in half for the wide slats & to around 30mm for the narrow ones at the top & front. The cast iron sides were sprayed with etch primer then epoxy enamel with spray cans.

I need to find another pair of sides, as I had a brain f@rt & bought twice as much timber as I needed. :doh:

Thanks. Great tips. That's the same finish I'm looking for.

One last question.

The previous slats were 1000mm. Can I safely get away with going longer?

The metal braces don't seem significantly structural.

If you're using hardwood longer shouldn't be a problem. I think mine are 1800 minus a bit for trimming. What I did do was run an aluminium strap from behind the top slat, down the back and under the seat, with a screwinto each slat just to give a bit of extra support. Probably not necessary, but hey.

Mine's 1500mm long & is fine with two 90kg people on it and only slight flex if I sit in the middle. Forgot to mention in my previous post that after ripping the wider boards, I went over the edges with a 4mm round over bit in the router, to match the existing edges.

I restored a bench 2 years ago. I just used a wire wheel on the drill and cleaned up the metal. This made a nice shinny gun metal finish which I liked so I just coated it with clear metal lacquer. I used some red oak for the slats and painted the wood with vinegar/steel mix to make it gray. I made the slats thicker than the original, hoping they will last longer and not flex as much. Turned out pretty nice.
