Hey the_chippie - I'm assuming you're a carpenter and don't work in a chipper
? Had a lad out yesterday to measure up my floors (28 sq yds) for glueing the solid acacia directly to the concrete. I'd arranged for him to come out before I heard of elastilon and I doubt I'll go with him as the price will probably be towards a grand and I'm not convinced glueing directly to the concrete is good (expansion problems plus very hard to replace it).
I asked him about elastilon and he said 'that stuff is a joke, I honestly can't understand how they can get away with selling that stuff', but when I asked for specific problems he could only muster 'listen, you just don't float solid wood, it's a bad idea'. Seemed like a classic case of 'it sounds different so it must be muck' without knowing the details.
I'm well aware of the problems of floating solid wood, but based on the web searches I've done, it seems like elastilon addresses these as the whole board is glued to the underlay and the underlay expands and contracts as necessary to keep the correct pressure across the boards to keep them together.
Would love to hear from a pro who has actually used Elastilon: good to hear it is a quick method but what are your thoughts on its performance once it is laid (any callbacks)?
I reckon I'll either lay 3/4" ply and nail into it or use elastilon - either one will save me the labour of this guy glueing it to the concrete, and I think both are better methods than the direct glueing. Would be interested to hear your thoughts. Nice one.
