AnhyFix

[Stef]

For anyone fixing onto a calcium sulphate screed then I would highly recommend using a gypsum based adhesive like TileMaster AnhyFix.
I carried out a quick test to see how well the adhesive would bond to the screed & as you can see it clearly does the job superbly.

Only to carry the tile over so as my bond wasn't broken.
There's a free standing bath going in there & the only way the waste can be fitted to the bottom is through that cut out into a bedroom cupboard.
It's going to fun trying to fix a tile in there once the bath is fitted.

wot primer did u use Stef?

wot primer did u use Stef?

TileMaster Prime Plus,
Mixed at a 4:1 ratio. Last Gyvlon I did I mixed the primer at a 3:1 & some of it skinned, 4:1 is perfect.
That AnhyFix is one damn good adhesive, sticks like the proverbial.

Will the tiles just be sat over that big whole when you come to actually tile stef? If not how will you be filling it? Sorry if I'm taking it off topic. Cheers

That will be filled in with granite & then I will stick a tile down into place.
It doesn't really need fixed as its just to cover up where the pipes will go, it will never see any foot traffic.

Can’t say I’m that impressed with that bond. You pulled itof the dabs with your hand and scraped the adhesive of the floor with hardlyany effort

Deano, I already had a go at that tile, 3 or 4 attempts to pull it up, that took a lot of effort to get up & those dabs didn't want to move.
If you have a solid bed under those tiles then it isn't going to move.

You were able to remove the dabs with a scraper and a smallamount of effort no hammer required. Do the same test with Weber SPF on to aS&C screed and see if you can get it up with the same action as you did inthe video

I've removed tiles easier than that from screeds.
I know what you mean but that adhesive had only been down about 12hrs.
The point I was trying to put across is that there are a few people scared from these screeds & they don't need to be if using appropriate adhesives & primer.

Adhesive seemed to bond well to the substrate. I doubt you could have pulled it up with your hand if you had buttered the back of the tile. Thanks for the vid Stef!

 

[Mr Tiler]

Any informative video is appreciated stef nice that ya took the time

I got my son to take a faulty tile out of a floor we tiled with anhyfix he took over 3 hours to remove it and no piece was bigger than a 50 pence piece the customer commented on it when I went back to silicone the expansion joints it was solid bedded and backed the adhesive is unbelievable and i am really really impressed with it ,I didn't watch your video just telling of my experience with it

You'll have to accept it sooner of later Deano.... Gypsum adhesives stick to gypsum based screeds....

 

[Spud]

What I was even more impressed with is the bond to the porcelain tile I expected it to grip the substrate but the bond to the tile is incredible

I will second that Gary,
The last Gyvlon I did I had to replace one tile, that was when I realised how good a gypsum to gypsum adhesive was.
I was a bit dubious about the bond but I shouldn't have been as it sticks very very well.
No doubt I will be needing to rip something up on this job, if I do, then I will take another video & show how a solid bedded tile comes up.

Maybe I will m8. I was just commenting on the bond in thevideo to be honest as it was posted as an example of how good the bond is and Iwould be disappointed with that as a bond myself. But it was only 12 hours oldso maybe that’s the reason.

 

[Mr Tiler]

stef did you have to break the first tile to remove it mate? seems it would of been a stuggle to at least remove without damaging another tile unless you sacrificed that one? cheers

Those were just 2 off cuts to carry my level/bond across where the bath waste will eventually be placed,
The 2 cuts were just put in place with small dabs of adhesive.
The 1st cut I used a pry bar to lift out & that second cut is being lifted out by my boy, I had already had 3/4 goes at lifting it with my hands, that's why I thought I'm going to video this.

I've still another 200+m2 to stick down on the job so no doubt there will be tiles here & there that will need replaced. If there is I will stick on another video & show how well AnhyFix sticks with a solid bed.
