bostik primer coming off when scrapping feet on

[average]

Have used bostik primer yesterday and it took some hours(4) to dry to walk on without anything coming off. I was going to put my self leveler on top however when i twist my feet on it firmly, some comes off. Would this be the norm or has this not bonded properly. I was of the thinking that this was supposed to be a better bond to the tiles before any addy or self leveler goes on.

Wold this be the norm or should i leave t for another day to dry more. If it comes off by scrapping my finger on it, has it not bonded properly.

None of the gritty none porous surface primers form a skin of any sort. No matter how you apply it, from my experience, but as said above. Bostik isn’t a reputable brand to professionals!

Ive put eco prime grip on smooth glazed tiles and when dry, I could sratch it off with my finger nails.

Yes, you can scratch off, but not peel off. The force of tile adhesive and tile onto the primer is not gonna pull it off

I haven't tried peeling mine thou. Just scratch and twist my boot on it. Will it be OK to tile on?

I would be tempted to remove it.......then dilute 50/50 and make up a slurry mix. Powdered tile adhesive and diluted primer...........diluted enough to brush. Then leave to dry.

You could always call their tech line/cus service this morning and check with them.
Odd as it seems I suspect its as it should be.

Would evostik 918 be a better choice

 

[Flintstone]

No, Evo stick is another diy brand. Use one of the ones mentioned in this thread

He doesn't really want it roughing up though if he's planning on levelling over the lot before tiling does he?

Evostik and bostik are the only brands in my local tilestore.

Phoned the technical service and the primer is as it should be. It reignites once self leveller or addy goes on top.

Rather you than me with this one, i must say.

The self leveler is down now so no going back. All we can do is wait and see. Worst case, if they lift, itll be on bostik to put right after them confirming this is how its done.

Don't worry they will find something you did wrong

 

[Rosco100]

If your trying to prime tiles,Mix some tile adhesive with the primer and let it dry before tiling Works

Was thinking this aswell to be honest.

I had the same problem with this s**t, beforehand I lightly grinded the tiles, washed and dried them, then applied primer, it took a long time to set and when it did it was a bit soft as you described ( came off when scratched hard) I took the chance and poured a Bostik deep leveling compound last job before Christmas.... first day back in January this is what greeted me, the primer came clean off the floor, I got in contact with bostik technical they came out looked at it and couldn’t give me a definite explanation as to what happened and told me to use bostik universal primer instead which after lifting the leveling compound I used and it worked ok.
They sent a new batch of special hardsurface primer to the tile shop, said it was ok to use so one of the lads that works for me had a nixer for his ant last week, tile on tile she got hardsurface primer from the same shop, he said had to lift a couple of tiles on Saturday and guess what... adhesive and primer came clean off the floor.
Avoid at all costs.

O rubbish. Tiles already laid ontop of leveler. Hope all is good with them and no lifting.
