What’s your methods on overboarding a plastered solid wall ?

 

[HardieBacker]

If you look at our new guide (attached) on page 8 it shows our masonry wall installation. If skimmed the same rules apply you just need to use a longer screw. We require a minimum of 50mm of the fixing into the masonry. Just increase the screw length based on the thickness of skim.

Hope this helps!

Much as I use Hardiebacker 250 to overboard floorboards quite regularly,no way in hell would trust just 12 screws to get the board secured and flat to the floor.
It might work in laboratory conditions but unfortunately I work in the real world.

 

[Dumbo]

For the time it takes why not a few extra screws . Belt and braces is best approach

Out of interest, what adhesive and fixing method are you recommending for holding up to 200kg per square metre?

We tested it with the robinson wheel, basically you add weight as the wheel goes over a floor until failure. The install with 12 x screws performed just as well as 39. We say its the minimum, more is always better but 12 we will warrant as long as our install guide is followed

More is always better especially on timber floors. But 12 x screws we will warrant, no bad thing to put in more you are right.

All we stipulate is that the adhesive is a bagged, cement based adhesive.

Flexible bagged adhesive

Flexible bagged adhesive

Doesn't have to be flexible even

The thing is,you will get raggy @rsed builders putting 12 screws in and say ''it's ready to tile'' and definitely won't be

Like any product we have installation instructions. If they are adhered to the product works no problem with the 12 x screws. But there must also be adhesive under the board, alkaline resistant tape, the boards staggered, 5mm gap around the room perimeter and most importantly the substrate is solid.

The drop to 12 x screws is designed to speed up and make the install more cost effective. Nothing wrong with putting more in of course. The markings (circles) are remaining on the board.

It’s the best thing since sliced bread!

You really need to clarify the tile or stone fixing method though.
A simple reference to BS5385 would cover you as a company.

The first time some moron spot fixes 20mm marble to Hardibacker and it falls off destroying something or someone - you have a potential problem because "it holds 200kg p/sqm".

Nope.
That'll be Kerdi-board John.

 

[Blunt Tool]

Kerdi board, honestly say 98% of the quotes I do wouldn’t accept price of them for prep work!
There are plenty of alternatives just as good at fraction of cost.

Hardiebacker board is a good reliable, dependable product at a competitive price.

Our products are tested beyond the required capability. For example if you search our social media we have images showing 200kg of weight on only a 300mmx300mm plate. The weights are the equivalent of over 2 metric ton being held on a board.

Now if someone were to spot fix then as with any product you could have an issue. No real tiler spot fixes. Anyone who does is asking for trouble.

There are. I used a pallet of HB this week for flooring.
I still would never use it on walls though.
Some customers just want to spend silly money on "the best".
So let them!

 

[Flintstone]

I agree with impish, for floors, Hardie and the like are great, but I wouldn’t use it on any wall, especially a wet area.
If the customer is wanting a top end room from the bones to the finishing touches then don’t disappoint, give them schluter. In most cases tho, any of the more affordable coated foam boards will do just fine.

 

[Blunt Tool]

I’ve only ever used Hardie on floors and never in wet areas as said.

 

[Time's Ran Out]

Nope.

Yep.
That’ll be down to personal opinion.
As others later - I only consider hardibacker boards in 6mm for floors.
Wedi / Jacko boards for waterproof walls.

@HardieBacker Muchos gracias for the goodies Luke. More than I was expecting but I will make sure I will post a selfie in those skimpy t shirts!!!

 

[Simon Dale]

Im going to use it so I can get some freebies

 

[Simon Dale]

I have a question. We have seven bathrooms all boarded and skimmed. We have channel drains and 20mm to play with around them. Can we overboard with 6mm and use tile adhesive to take out some of the 10/15mm dips in the boards. Obviously they will be mechanically fixed as well ? The tiles are 6mm thick.

 

[HardieBacker]

As long as the substrate is solid in theory shouldn't be a problem. We now only ask for 12 x fixings too on 6mm on the floor. What might be better is us just popping along to have a look if that would suit Simon?

We can usually come up with a work around/spec to most installs! We hate to say it cannot be done.

 

[Simon Dale]

Is their a rep in Kent ?

 

[HardieBacker]

We do cover Kent. Send me your details on a message and I will get them to give you a shout mate
