Kitchen floor

"Is it a floating floor?" - Are there screws in the chipboard???

You cannot screw chipboard to Kingspan insulation so no screws = no joists = FLOATER!

Simples!​

Would you tile it though? or have you tiled one? just intrested to see what other tilers do in this situation. Is there anyway DavieA can get rid of the bounce?

Yes I am one of the few that have tiled a floating floor, but I used judgement first, and walked away from some floaters.

Question: How do you eliminate bounce from a floor that has no foundation to secure to?
Answer: Walk away fast!

I wouldnt tile a floating floor just due to my lack of experience to tell you the truth. My intention is if the chipboards on joists screw 15mm ply to remove bounce and then id like to lay 6mm backerboard of some sort over the ply and fix with spf addy and screw allowing me to build up under the backrboards if the floors high in areas allowing me to get a level surface to tile on without having to lift tile to adjust. lay ufh and slc over wires giving a smooth level surface to the put a sold bed and tile.

Is this sound guys?

OR remove chipboard and lay thicker ply onto joists????

 

[Daz]

Yeah defo the bounce must go, and first question will be is it floating although if it has hatches cut in it can it still be floating and is there anyway i can tell?would ply and screwing to death be suitable?

Surely no further advice can be provided, until we know if it is floating or not??

It its a conventional floor it will be joists suspended over a void. It its joist sat on a concrete base with insulation between then its still floating. I have seen them done in conservatories with mixed results, some fail and some dont. The general concesnus though is to not tile them.

It its a suspended floor sometime there are brick piers under the joist to stop the deflection that can be packed out to stop it, or additional ones added in.

Hi all, went to have a look at the 25m2 kitchen floor and the floor is not a floating floor and is of standard construction with chipboard nailed into joists. There is some squeeking and movement in areas but not a lot and the floor is made up of 3 rooms knocked through into one.

Travertine or slate is what the customer is looking to use and UFH matting.

My thoughts are to first,

Screw chipboard in areas of squeeking,
Lay 15mm Ply accross whole floor screwed at 300 centers to elimenate vertical movement and create one solid floor instaed of 3,
Bed UFH matting to PLy with a thin bed of SPF adhesive(keraflex most likley)and allow to go off,
Pour Mapei renovation screed SLC over mat to protect and give a good suface to tile on,

Not to sure wheither its recomended to put a Decoupler down ontop of SLC or is it over kill and will mapei SLC bond well to ply or is primer required?

Then tile as normal.

Correct steps?

be careful screwing the chipboard down if you don't know whats under there. there may be a notch out of the joist for pipes or cables causing the 'squeek' and you may hit them by screwing in that area. i know cos i've done it a few times :mad2:
