Best adhesive for sticking down 5mm ply onto chipboard

[wertert]

Hi All

Hopefully an easy one for you. I need to lift a bedroom floor slightly so that it is approx level with the bathroom tiles when carpeted. I've got a few sheets of 5mm ply which i'm going to lay over the existing 22mm chipboard T+G floor. Should bring it up enough. Not sure if the t+g was the moisture resistant type. I was planning to use 12mm staples in a staple gun and/or 20mm screws every 200mm.

I would also like to glue the ply down. Any ideas what type of glue to go for ? I was thinking normal PVA but maybe this is too weak. Does the fact that the boards maybe moisture resistant affect the bonding ability of the glue ?

Once the ply is down it's gripper rods / underlay and carpet.

Many Thanks

Wert

personally i wouldn't glue it, screw it down at least then you can remove it again if the need arises.

Screws would be fine, so glue would be belt and braces.

Neat pva should do it, the only other I can think of is grip fill, bit ott tho and expensive.

Someone at work suggested using flexible tile adhesive. Sounds like a good idea to me... what you think ?

Screws every 200mm.

PS wear knee protectors!

Being in mind this is only having carpet, I'm sure it's not that crucial.

Screw, dont staple/nail. I initially nailed some ply as an underlay before putting down wood floors .. was creaking like a crazy thing even before I got to laying the real floor.

Screw it as mentioned above.

If you glue it and any part does not adhere or lifts in future you will have a noisy floor which can only be rectified by tearing the ply up and that will damage the chipboard.

Screwing allows you to lift parts if you need to.
