foil back but moisture resistant!!

[hail hail]

Told client to order boards of foil back boards because one side is damp proof which is the foil side. Turns out he ordered sheets of moisture resistant plasterboard!! I've only ever plastered a few of these but the builder always suggested I throw a thin coat of bonding on first. Now I'm wondering should I Zend these all back or are they OK to skim straight onto without the need for bonding?

 

[S a plastering]

Vapour mate not damp

 

[ggb plasterers]

Green moisture boards are fine ,just skim as normal

Same thing lol. Only kidding, got my wording mixed up

Are ya 100% sure. If it is straight skimming onto them, does the skim hang longer because its different backing

Put a grit on them ie thistle bond it pre grit etc

Not enough in price for this its priced very tight and no room for throwing a coat of TB on it

They aren't going to do the same job as the foil back boards though

As above, it hangs more I find aswell.

Also you say you have no price for the TB but if client ordered them it's his problem not yours so it's an extra surely?

I didnt think you could dab onto foil back ??

you were going to put tight coat of bonding on though..surely that is cost saved it don't need bonding coat

How many boards are there?

 

[TonyM]

Thermaline Super would've given you added insulation, a vapour check layer and they're dabbable.

Then without the grit the moisture are not protected you might as well use wall boards . Pre grit is only 13 a tub

Yea listen to the builder. He knows best lol

Looks like their going back then because I'm not confident enough to just skim on them. One, I don't want the skim to come off and two, don't want to be standing hours waiting on it turning.

 

[cooptaza]

Skim will go off regardless. It's the bonding coat which will hang for hours. But fair play to stick to your guns.

Yes but sometimes skim can hang to. I've had this before. This is a cold damp cottage and could see it hanging if these boards are waterproof. I'm scratching my head wondering what in the name of good fcuk to do. Will I send them back or throw on because one said above its ok

 

[CTPlastering]

It may hang around am sure it wouldnt be that long to be a problem , if anything flaten in etc and hoy sumit else on !

Ya, farted it out. As the aul saying goes, ya can't hold what ya don't have in your hand

 

[algeeman]

Most hotels in the uk new build have moisture boards in shower areas.
Roll unibond on it.
This is usualy the spec.

Someone mentioned to me uniboard aren't for these boards

 

[skim_I]

I've skimmed over MR boards many times without problems but the right way is prepare with grit or tape and fill.

Did you notice any difference at all even thou you had no problems. Can't seem to get grit PVA anywhere here

Make yer own , sand cement and pva or latex s&c job done n cheaper

These are the only boards to use if the cottage is cold and damp. foil back and moisture resistant will fail in time.

@cuntyfcuk. Didn't notice any difference tell you the truth
