Tiling on to chipboard flooring

[richardbell81]

Would BAL single part fastflex do the same job? Only thing I want to make sure is that the floor is as water tight as necessary... I suppose if the tiles are fixed and grouted correctly the floor should be water proof enough?

grout is not waterproof. if the floor is going to get wet, i.e a wet room then you should tank the wet area before tiling

Hate to repeat myself friend, but you must call the BAL technical helpline and specify the substrate, conditions, type and size of tiles and the requirements of the installation (any F1 cars driving over it?)...it'll be an instant solution to your questions...

Just to throw something into the mix, quite a few rubber crumb (liquid and powder 2 part) manufacturers state that their products can go straight to green chipboard providing there's no deflection. Done quite a bit of site work where was 2PF was specced straight onto chipboard and there's never been a single failure with any of the floors. Personally I'd overboard it on a private job though.

most state grout is mold proof to not to mention waterproof ,would defo overboard with 6mm hardie

My advice is to get a qualified tiler round to take a look at the job and pay him/her to take care of it, or at least advise you exactly how, why, and what with it should be done. It'll save a lot of time...:smilewinkgrin:

Called BAL Technical. To summarise what they said...

- Don't prime surface (just ensure there is no wax coating by sanding down)
- Adhesive: Single Part Fastfelx
- Grout: Wide Joint + GT1. additive.

Also said that on such a small floor the movement or deflection should be at a bare minimum.

So, there you have. Thanks again for all your advice!

Quick question before I begin tiling... Does anyone know if I am best butter backing the tiles with the adhesive as well as using the solid bed tipped trowel? The porcelain tiles are 600x300 with diagonal ridges underneath.

Lift the first tile you lay and check to see what kind of coverage you are getting, you are after 100% coverage! chances are you will need to back butter as well with that size tile. I would still advise over boarding with a 6mm cement board.
Good luck

the advice given on this site is sound. bal have products that go against British standards, learned and practised by many tilers on here. They have a product that they claim can go straight onto tongue and groove boards, but i dont think that you would get many tilers on here that would do/trust it tho. so it is entirely up to you. The advice from the pros is to overboard. take it or leave it.

believe me... i'm not doubting or questioning anyones expertise. If i could afford to get a professional tiler in to come and do the whole job, do you not think i would? However, I'm trying to do as much of the work as I can myself as this is our first house and we're on a very tight budget... i'm sure most people have been there at some point???

On this occasion, I have b*ggered up by not allowing extra height to tile over the newly installed woodchip flooring. If I could go back and do it all again then I would but i've just come slightly to far to realistically do that without causing major problems so I need to try and come up with the best solution possible, which may not be ideal, but there you go. I just hate doing 'DIY' jobs which is why I asked the experts instead of ploughing on.

Apologies if I caused any offence.
