Help!: Priming walls

[Jimmy Doc]

Hi all, Im in the middle of doin my wet room and was priming shower Walls (sand/cement and ply) before tanking, I noticed that there was a skin on the sand/cement Wall when it dried out, primer came with tanking kit, not PVA, is this normal, just want to know before I apply paste, thanks

[Sir Ramic]

Paste ????
What primer is it and has it been diluted ?

[merlecollins]

What tanking kit do you have?

[Jimmy Doc]

No wasn't diluted, tanking kit is a paste and you tape all corner's, what should I do

[Sir Ramic]

You really need to answer questions so we can help.

Manufacturer?

[Jimmy Doc]

Tanking kit is from bondmaster

[Sir Ramic]

Sounds like you have applied it neat and yes it will "skin" It should have been diluted either 1.1 or even 1.3.
Have you read the instructions ?

[Jimmy Doc]

Yes applied it neat, my mistake, what should I do now?

[Sir Ramic]

Is it a rendered wall ?? Rub it off with sandpaper or a rubbing block then prime again at 3.1 dilution.

[Jimmy Doc]

Yes it's a rendered wall, done the ply also but it seems ok or should I sand this to

[Sir Ramic]

I would as if it has skinned then al you will be fixing to is that skin.

[Jimmy Doc]

Do I have to bring it back to surface or just ruff it up, just use coarse sand paper?

[Sir Ramic]

Just remove any evidence of the primer skinnning over.

Hang on before you do, what does the instructions say about use.. some do get applied neat..?

Checked Dave it said 1.1 or 3.1 for sand and cement render. 2 coats neat for polished plaster.

[Jimmy Doc]

Hi save, just says on bucket that kit came in to prime walls first but on primer jar is says dilute 1:1 for ply and 3:1 for render, I applied it neat to all, think I'll have to get sand paper out or what's easiest way to mend

[Sir Ramic]

Try this BONDMASTER_TILERS_PRIMER.pdf

[Dave]

Ok.. then you have boo booed..

As stated above.. sand it to key it..

[Sir Ramic]

No great harm done and better sort it now than regret later.

I'd be removing the ply....
