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

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

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.

You primed tiles to be tiled with more tiles?
