Tiling Board

[John K]

Good Morning, I live in a 1930's Bungalow and I am getting my Kitchen and Bathroom floors Tiled. It is a bit more expensive than I thought and my Contractor is now saying I need a Hardie Tile Backer Board to go down on top of existing Floor Boards. Why do I need a Tile backer Board as it is a bit pricey?

Many Thanks John K

because you cant tile directly over floorboards because your tiles will crack due to the expansion in wood. It might seem a bit pricey now but would be very pricey to put right if not done properly in the first place.

you dont need to use hardie backer boards, you can use ply ,make sure it is of good quality and no less than ten mill in thickness then make sure it is screwed down evey four inch square and prime the boards before tiling (do not use PVA as your primer)

min 10mm ply do you have a problem with that, if so say what it is

and also before you make a comment take a look at how long i have been a tiler for then add one more year,expierience counts in this job i would say ,and i have plenty of it, no need for the hadibacker like i have told the op

Heard of 4mm, 6mm, 9mm, 12mm, 18mm, 22mm & 25mm ply. Never 10mm ply.

Hardi for me all the way. No hassle in priming boards, no worries about needing a Flexi adhesive (unless UFH) & guaranteed no movement in the substrate!

Don't get me wrong, you can use ply. Would be a minimum of 18mm for me (unless a high humidity area such as a wet room where 18mm marine will be required) but by the time you add the cost of an SBR, the hassle of priming the underside & edges you'd be better going the proper route

Hardie boards are more stable than ply wood, as it can come in varying degrees of quality, and can delaminate.
So people opt for hardie or other methods.
But don't tile direct to the floor boards, yes it will cost you more money, but as PC says, do you want the risk of doing it twice?

How does how long you've been tiling for come into it.
My comment refers to the "10mm" thickness you state. See point 1 below. But in anticipation to your next little outburst i've made note of a few other points:

1) Thicknesses of sheet material is measured to the nearest mm in conversion from imperial (yards, inches etc. 39 years of tiling you should be familiar). 9mm (3/8's of an inch). I don't believe there is such thing as 10mm ply. I'm open to be educated if you want to show me where it does exsist though.
2) Up until reading your post i was always 99% confident that BS states a minimum of 15mm (so the size would be 18mm or 3/4's of an inch in old money)
3) Overlaying with ply takes more prep than i tilebacker board would
4) a 6mm cement board or tile backer is less effected by tempreture changes than ply.
5) 6mm board as above would or is less likely to effect any transition to adjoining rooms.
and lastly, possibly the most important. It works out much cheaper to do it in hardiebacker than it does ply.

but..................I could be completely wrong i suppose.

right first of all like i said expirience counts ,(but not obviusly by you ) by your childish comments take a look back it says 39 + 1 wich makes forty years as a (time served six year apprentice) not a 6 weeks tiling course and then im a qualified tiler type of person ,the ten mill was just a example to the op,aswhats right and whats wrong,the problem im finding here tha there seems to be alot of know alls ( Know nothing) type of people,sit up and please take notice that i have been doing this job along time and i think i deserve abit more respect than you are giving,you mention 18mm ply but i am presuming the op doesnt want a front doorstep at his bathroom or kitchen door ,just recently i tiled a 4mtr bathroom floor told the customer to put min 10mm ply ,he put 6mm ply down 360 screws in it ,would you have tiled it? i guess not you woul have told him to take it up and put your fancy boards down i couldnt believe the ammount of screws i could not refuse to tile it after seeing it ,i will also tell you that that floor will still be down when you are no longer tiling with a gaurantee ,does that make me a cowboy tiler in your eyes probrably yes ,and that is where many years of expirience counts

I'm sorry? None of my comments have been childish. You've gone nuts over what exactly here? My comment refered to the non-exsistance of 10mm ply. At no point in my first post did i insult you. I didn't even insinuate anything about tiling itself. You've read into my comment what you've wanted to read. Maybe it's you that needs to ask questions first perhaps?#

So you've been tiling for 40 years. Great. Personally i think the experience is only as good as the experience was. Would someone with half the time served therefore be half as good as you? I don't think it works that way. I've made no reference to the quality of work you do or your recommendations.

Lastly, you're kind of arguing most of my points for me in your last post. "front doorstep" comment. The 10mm was an example of what's right and what's wrong you say? So which one is your arguement supporting?

You demand respect because you say "you've been doing this a long time". Maybe you should calm yourself a little and give a little before demanding it in return. If you've had a bad day and want to vent, get a hobby.
