Which Hardiebacker????? - Hardiebacker Advice

[Perfect Tiling]

Hi all...hope everyone is well.
Hopefuly this is a quick one...Which hardibacker do you guys prefer to use as an overlay for suspended timber floors. I used to use the 250 (6mm) version and never seemed to have a problem, then I spoke to BAL and they said they would not recommend using this unless I used a fully flexible addy. I like to use their single part flex but they say I must now use the 500 (12mm) hardibacker or they wont guarantee it. Customers aren't too bothered which one I use as its still better than 15mm or 18mm plywood. Just thought I'd get some other opinions. Many thanks.

i use 6,mm,if bal wont guarantee it then use mapei and 6mm

I too would give Mapei a call on this one I think.

The problem I have up here is limited suppliers for adhesives. I have to do a 100 mile round trip to get materials at a reasonable cost from Topps. As I said, I never had a problem with tiles failing on the 6mm so shouldn't need a 25 year guarantee. Thanks for your reply...appreciate your time

I always use the 6mm, never had a problem

Try going to CTD or Collinsons and open accounts. Topps are way too expensive. Decora do BAL too but it is retail prices - Ouch!!

My round trips to both these are like yours but it is something you just have to do!!

CTD...Collinsons...where would my nearest ones be at. I live and work in Elgin so am about 50 miles from Inveness and 70 from Aberdeen. The BAL SPF costs about £21 from Topps...believe me that is cheap compared to getting it local. I tend to use dunlop addy for below the hardibacker as its a lot cheaper and seems to do a good job...as i say...no failures over the years...just that BAL tech line comments got the brain going!!!!

Both in Inverness. CTD do Mapei and BAL and Collinsons do BAL and some ardex if you ask for it. Sadly no Tile Giant in these parts......

Always thought the rule of thumb was 6mm for overlaying the floor and 12mm for going onto stud walls.

Have always used 6mm on the floor and never had a problem either.

Sounds like major overkill from that adhesive comp..

I too have used it with Mapei and no probs.. solid as a rock..but as stated by hardi the substrate must be sound to start with.. no point using it if the floor is bouncy etc,

 

[The Legend; Phil Hobson RIP]

As above 6mm on floors (glued and screwed) flexi adhesive. 12mm on walls. No probs

Its not better than ply if there is any deflection in the floor as it wont stiffen or strenghten the floor.

I use 12 for wall and if the need arises 6 for the floors

 

[doug boardley]

slightly deviating from thread but....I was wondering why hardie don't make their 250 boards 1800 x 900, that way you could herringbone them and have all joints staggered?

 

[Scott]

Weight? All this stuff and nonsense about making things too heavy?

Where do you guys buy your hardiebacker and what kinda price you paying roughly???
