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.

What is the background and did you follow dilution rates

 

[judge]

Was it supposed to be diluted first and what have you primed ?

 

[Old Mod]

Sounds like it’s skinned, maybe too concentrated.

Was the substrate dry and clean before applying the primer?

Was the substrate dry and clean before applying the primer?

Washed with sponge then dried with a dry towel to take dust off. Straight from the 1 litre tub. Didnt dilute. Didnt say on the tub to dilute.

Does this happen often

What’s the exact name of the product?

Only if it needs diluting

Some primers must be diluted first.
Others require a build up of different strengths.
Some primers will readily sit on top like a skin if not applied correctly.

Tile on tile, that what you mean?
You primed tiles to be tiled with more tiles?

primed the tiles for some self leveler on top because some needed leveling because of low spots. Tiles can go onto tiles if primed

Used what tile store recommended. If its glazed as you say, should i take it all off and redo with different primer.

Actually, reading the info it sounds like it should be suitable.
I've never used it though.

The best I’ve used for this type of application is called Super Grund from Isomat.
It’s a resin based grit primer.
It’s like painting on neat sandpaper.

then again, I wouldn't use Bostik anything.

Should it be well bonded as when i turn my boot on it with force, nothing should come off

Got to admit I tried their website couldn't find anything of any use

I can walk on it, rub my finger on it and nothing comes off but if i scrap my finger or twist my feet hard on it, this is when it comes off. Would this be the same as the skinning as yous think it is or will mines be ok in the morning. If not, should i remove it then redo.

 

[GoneGuy]

I would check it in the morning if it’s still the same I would remove and use a better brand

Did you clean the existing tiles and de-grease them?
