Adhesive for bamboo flooring onto chipboard

[redtop]

so the chipboard is a floating floor (with 25mm pir below). No UFH. Do i need to go to the expense of flexible adhesive? The sika 54 is coming in at 800quid for 100m sq!

Why are you bonding it down?

I have found that bonding the floor gives a really solid finish.  Whether it is £800 worth of solid is debatable.  It also takes almost twice as long to fit.  Maybe a thicker click fit floating floor with decent underlay would be just as good and less expense and ball ache.

Agreed, but, the OP has already got a light floating floor, so bonding down onto that is not going to give the same solid feel as you’d get when bonding to a fixed substrate or screed etc, so the question has to be; will there be any added value here in spending money bonding this down? The bamboo is already a very dense material so will sound solid underfoot regardless imo.

Well my thought was, glued down Sticks it to the Substrate, floating doesn't and therefore introduces a bit of bounce. I already have a floating floor so it will never be solid like concrete, but floating on floating equals bounce squared. Well maybe not, but it would be bouncier than glueing.

What does the supplier say in their instructions to use?

“Bounce squared” now there’s an equation I’m not familiar with ?, has a nice ring to it tho.

One that I did was 75mm Celotex, 22mm T&G chipboard and I think 16mm strand woven bamboo stuck down with silane adhesive.  It felt very solid.

I have a similar one for calculating size of soakaway when you leave it to the end and cant get a digger in. Dig a big hole until knackered, leave it during pouring rain. If no water in bottom its big enough. Feel free to re use

It will be “more solid” and that may be all the justification that you need  

Go forth and glue, and report back here with your conclusion please

“Ime wrong”? “I’m wrong” would have got you off that hook lol
