spackle (cast) in front of fireplace

[viktorj]

Hello

I have installed a new wooden floor and instead of laying tiles in front of the fireplace, I am thinking of casting a small slab in front. What should I use? And can I let the concrete rise about 10 mm above the floor and extend it about 10 mm over the floor to avoid adding any metal strip??

Grateful for a response //Viktor

Handling firewood tends to generate quite a bit of small debris. I would have preferred if the slab was a few millimeters lower than the rest of the floor, so the debris doesn't spread all over the floor. If you have a floating wooden floor, there should also be a few millimeters of expansion gap between the wood and the concrete. However, this would also require a transition strip to cover the gap.

It's probably as you say that it's better to place it below the floor. But I want to raise it to avoid a metal strip. The idea is to place some form of foam rubber or similar so that the concrete doesn't lie directly against the wooden floor. The question is whether one can construct some form of cove that provides a nice rounding above the floor. What do you think of that?

That doesn't sound impossible, but it probably requires great precision and a lot of fiddling with the mold. Reinforcing the overhang might also be a bit tricky. A simpler alternative might be to cast up to floor height and place/fix/glue a loose slab on top of concrete or natural stone. There are stonemasons who can make custom-sized slabs with beveled edges.
