Harosecur - gimmick or good?

[MortarThePoint]

I've just discovered this plastic strip product that you can put between ceramic surfaces. It sticks to one of them and conforms to the other. My main use would be below floor mounted toilet pans.

 

Has anyone used it or have any thoughts about whether it's worth it?

Nice idea if it works.

 

I hate sealing around toilet pans and it never looks good

You still need to apply a bead of silicone around the joint when done with this though so I think it's more about avoiding the ceramic on ceramic contact if that is indeed a problem

In which case whats the point?

 

Silicone works just looks poor when it has to be thick, least it does when I do it haha

@Nickfromwales when you screw down toilets to a completely tiled floor do you use this stuff, pop some silicone between the pan and floor or just sit the pan straight onto the tiles?

 

Definitely needs a bead of sealant around afterwards but wondering if anything between pan and tile?

@MortarThePoint I noticed something similar looking in the diagrams for my wall hung toilet but couldn't find anything resembling this stuff as there was not any text in the instructions to tell me what it actually was, just drawings. 

I tried putting some Armaflex tape on the back of the loo pan as an isolator but it had too much give in it and the loo flexed when sat on.

@Nickfromwales I'd be interested in your thought on this too please, as my bathrooms are about to be siliconed so I can still easily fit some to my toilets if I need and can get hold of some. TIA

My floor mounted toilet pan had this less than useful picture in the install instructions. 
 

 

Which I assume is tile adhesive. But I still don’t understand how you can have adhesive on the bottom of the pan and then do all the movement to fit it to the two connections. Wouldn’t it make a right mess?

Just found this blog detailing an approach, which I quite like. Install toilet, raise on packers, silicon under pan, place back down. This guy didn’t want to drill and screw mount.

If doing that, I'd be inclined to trace round the bottom on the pan with a pencil, move it to the side and put the silicone down onto the floor and the place the pan back in position. Pencil line would then get covered by the later silicone bead finish.

 

I'm may use this approach in another room where I can't drill the floor, but tempted to use CT1 for sticking the pan down. Same approach though.

It’s what I do. 
 

@Barnboy

 

I lift the pan up on packets, drop it into clear CT1 (NOT silicone) and pull the packets out. 
 

Clean off the displaced CT1 with a load of baby wipes, cleaning it back so you can’t tell it was ever there, leaving a crevice at the bottom of the pan where it meets the floor. 
 

Use CT1 Multisolve to clean the floor. 
 

Leave to cure, and then apply cosmetic silicone to crevice.

Not bolting down….

 

If there’s bolt holes I fit the fixings with decorative cover caps with silicone, cutting the fixings short of the floor, “for display purposes only”.

Have you ever removed a toilet that is stuck down with CT1? I can't think why, maybe if broken or something. Is it possible to remove without trashing the tiles?

The only time you need someone to have compared the fixing strength of various adhesives from strongest to weakest, eg. CT1 to Silicone Sealant. 
 

Ideally something in the middle of these two extremes. Gripfill? (Awful stuff)
 

Sounds like a use for all my left over tile cuts. Fix them together and see what makes the middle strength bond.

@Nickfromwales 

What about wall hung toilets ? 

I asked a 2 local pluming merchants today who both said that they'd never heard of these tape /strips .

Wall hung toilets……defo don’t need sticking to the floor. 😉. 
 

My work here is done. 🤣

Anything is possible. 
 

5 loafs. 
 

2 fish.

 

You just use a craft knife to slice it away and off-she-comes.

They don't need sticking to the floor, but do you fit these isolation strips / tape between the pan and Wall?

Never. I use them as cutting templates for plasterboard and tiles, then bin them.

 

CT1 again here, same method; wipe back CT1 and top coat of cosmetic silicone.

Gripfill??!! Have you been at the cooking sherry?

 

CT1, comes off plenty easy enough if you need it to. Multisolve removes all residue.
