Help for a n00b please

I would never use tubbed adhesive on floors m8, i beg you to take it back and get some cement based flexi adhesive, or your gonna have big problems in a short time.

First the background...

12 sqm dining room, floating chipboard floor and the skirting boards are staying down (she has decided). I am boarding out using 12mm exterior marine ply, screwed at 200mm centres with 4x25mm chipboard screws. Then sealing with pva/water and using Unibond flexible ready-mixed adhesive & grout.

Ready-mixed? You'll be needing a single part flexible cement based adhesive at the least for that. And you'll be mixing it yourself.

First question - should I leave expansion gaps at the edges and/or between sheets of ply?

2 - 3mm for 12mm i'd say. (I'm pretty sure the BS is 18mm marine ply you know) Call BAL Technical on 01782 59 11 20

Second question - I intend to Silicon around the edges against the skirting board. Should I grout first and run a bead over, or just use Silicon in the perimiter gap?

Grout before siliconing generally. But if you have the tiles butting up to the skirting, you're not using the Silicon as an expansion gap (asif it the tiles were up against a wall, or other tiles) you're simply using it for the athstetics, so if your skirting is pretty solid, and you're using flexible grout, give the grou ago in the perimiter esge but have you Silicon ready for the not so solid areas where you'd expect to see cracking of the grout due to expqansion and retraction of the skirting.

Hoping to get the ply done this weekend, any help would be appreciated. I will take some pics of the stages to post if it would be of interest to anyone.

Dunnster......!

We love pictures - hope you've taken some before shots! - Stick them in the 'Photo Gallery' area on the forums or Private Message (PM) for my email address if you want me to stick them on the site for you, should you get stuck etc.

Still seems to be a bit of confusion with single and two part adhesives, single part ie bal rapid set/ rapid set flexible. Two part ie bal fast flex and additive. If its being plyed then single part is more than adequate, talk her into removing skirtings m8, far neater finish and no worry of cracks round the edges as dan mentioned. Stick to what varley said and you cant go wrong, good luck🙂

It is the 'tiling on wooden floors' flexible adhesive.

We also have a tub of ready mixed adhesive for wooden floors,this is not professional gear.I would only ever sell it someone if I disliked them intensly.It does actually work but the problem is how long it takes to set,if on ceramic tiles ( clay base ) one weeks holiday at center parks before it's set propery,if porcelain tiles well...book a 3 week cruise on the QE2,and a weekend break in London!!
