I have some paving steps to lay in concrete, and will buy a trowel for smoothing them off.

There's an enormous range of trowels/floats available, with almost identical ones for plastering and for concrete laying. Can I use one trowel for both purposes?

General example:

https://www.bunnings.co.nz/kango-280mm-gold-stainless-steel-pre-worn-plaster-trowel_p0098421
280mm Gold Stainless Steel Pre-Worn Plaster Trowel $43

https://www.bunnings.co.nz/kango-305mm-gold-stainless-steel-concrete-trowel_p0098449
305mm Gold Stainless Steel Pre-Worn Concrete Trowel $40

This is not a direct product comparison, its a more-general "what's the difference?" question. I see the Plaster one is 25mm shorter, but has a longer "backbone" compared to the Concrete one, which has more "fore and aft deck" (?) exposed before the handle starts.

This is purely about rectangular floats, or smoothing trowels. Not pointing or mortering, and not gardening/weeding. What would stop me using the same tool for both jobs ?

    What would stop you? Belief in marketing hype. Do you think the difference warrants buying both tools? I do not. As long as you keep the tool clean and rust-free, it should meet both needs. – peinal Dec 17 '20 at 15:41

    Steel trowels can be used for either plaster or concrete. Each will produce a smooth, flat surface. A wooden trowel will give a rougher/coarser finish. – ojait Dec 18 '20 at 0:14

    Well, having noted the obvious 25mm difference, I'll point out that you failed to notice that the Plaster trowel has a cool "target" icon, while the Concrete trowel is only adorned with an underline for the company name. There's also a difference in the yellows, but I couldn't quote the Pantone numbers without looking them up. I think that probably sums up the differences. Oh, that and $3... On the bright side, they're both made out of "Gold" (or so it seems) and that makes either a steal at only ~$40!! – FreeMan Dec 18 '20 at 17:46
  • Right - so its market segment flooding and there's no practical difference. – Criggie Dec 18 '20 at 22:06
