I'd like to build a corner bench seat in my outdoor area. I like the idea of it being out of some kind of board that I can feather finish to give a concrete look. Do you know if there is a timber sheet available that can be used outdoors without warping or rotting?
Here is an image showing the kind of look I'm going for but I wouldn't use the timber slats.
Any help would be appreciate!
Looks like a cozy spot @Gina - will be great to see what you come up with.
If you're going for a concrete look, why don't you just make it a concrete bench? Brick it up and coat in concrete. Will be longer lasting.
Or am I misunderstanding your plans?
Great project @Gina. I hope you get lots of helpful ideas and advice for this build as well as many others in future.
Let me also extend a very warm welcome to the Workshop community. You will soon find we have lots of helpful members like @ProjectPete who are only too happy to share their experience and knowledge.
Please let me know if you need a hand getting the most from the site.
Blueboard (fibre cement sheets) would be a good option and may save you some dollars. Then coat in cement.
Otherwise marine grade ply should do well for you. You could either coat it in cement or just seal it and paint it with a cement texture - I'd suggest it's not as long lasting as the option above.
If you weren't going for the cement look you could just use merbau decking or something similar.
