    Hi all,

    I'm want to lay Karndean Van Goch planks on my bathroom floor (1.5m x 1.7m area excluding tub and fitted cabinets) as a DIY job and I understand that the standard instruction is to overboard chipboard with ply, then use featherfinish etc. etc.

    However - in my case I've relaid the bathroom floor using Egger Protect boards, glued and screwed to the joists, rock solid. If you're not familiar with these boards, it's T&G 18mm chipboard but with a bonded textured membrane on the surface that is waterproof and suitable for tiling directly onto:

    The floor is therefore dead flat and smooth with no lipping at the joins, with just some screw heads to fill flush.

    Would you glue LVT directly onto this surface and if not why not, other than warranty etc.?

    The lipping will come. One wet fart and those edges will swell up

    Well, the description seems to suggest it can stand up to bit more than a wet fart!

    "EGGER Protect can be fitted during light rain hence minimizing work stoppage on the site

    After fully fitting the board, you can leave it exposed to extreme weather conditions for up to two months."

    But I get what you're saying.

    Over time the chipboard will move and it can then leave a high point where all the joints are. Yes you can glue to them if you want and take the gamble.

    Well, it's been down bare for the best part of 18 months in a working (albeit little used) bathroom and is still perfect for now so yeah I think I'll crack on... maybe do some adhesion testing with some offcuts first.

    I would ply it also.

    This is why I don't usually bother with these posts, ask for advice from the professionals yet has no intention of taking it either way :rolleyes:

    They know best, my fish fingers said 12-15 mins but I was hungry so just put them in oven for 5 mins and I’m still here.

    Well, in fairness, my question was whether anyone has glued to Egger Protect boards as my query was around adhesion to the surface of these specific boards, seeing as they're a very different animal to regular chipboard in that respect. It seems nobody here has.

    If someone had said "Yes, I have done that, it didn't work because XYZ" then no I would not proceed.

    Anyway, I filled the screw heads and around the board joints and sanded the whole lot to the point that I couldn't feel where the joints/screws were with my eyes closed and got the planks down with F44. Very happy with the finish.

    I have set a reminder on my google calendar and will report back periodically as to how it's holding up. Let's find out if I really should stick to my tea and biscuits.

    Well doesn't time fly! 2 years later and I'm back with an update as promised.

    Having been well used and pretty much flooded a couple of times by the kids splashing the water out of the bath, it's still perfect, flat as you like and all joints tight as the day it was laid. Just lucky I guess.

    Update again in another 2 years I guess. Perhaps by then the kids will have left me alone long enough to make a bath panel.
