Green moisture board Adhesive suitability

[DavieA]

Hi all i was pricing a job yesterday in which the customer has bought all materials and has purchased Unibond ready mixed Anti-Mould adhesive and grout which aint cheap stuff price wise but ive never used it so was had a couple of questions,
1.Will i need to prime the green board before applying it? (not normally needed with ready mixed addy) and
2. Can it be used without any problem on green moisture board or does this board require a different addy type?

Thanks for any help you guys can give.

Dave.

Belows a link for the addy im on about.

don't think you will need to prime,but always check the tub!
should be fine on the moisture boards!

As David says...you will be fine. It will just take a bit longer to dry as the board doesn't suck out the moisture as quick. You might find the Unibond isn't great stuff to use though......

Cheers for the faster than fast replys! Didnt think id need to prime with the tubbed stuff and tiles are only 200x250 so should still dry out for grouting the next day. Spoke to a woman on there support line and she said it has to be the extra hold unibond addy and standard isnt suitable for green board but think she may have been talking out of a hole in her head as it didnt make sense to me, any thoughts on that? Also interesting grumpy says its not great to work with ....whys that then? just so i know what im letting myself in for, LOL

because grout and addy require different characteristics so its just horrible to work with. i would ask him to get a refund for it and you go buy some mapei ultracolour grout and a good tubbed addy like bal grip or something

Just the way it may spread, the cosistancy etc. I have not used it for a while now so it may have changed but I recall it not being very nice and I think I remember seeing other posts in the past saying the same.

because tubbed stuff is dispersion adhesive and the boards are moisture resistant where as bagged stuff is cement based making it dry out a lot quicker so it will stick to the boards quicker!

bal white star for the extra £1 atub it's so much easier to work with!

ok so im seeing a pattern here:lol:. So return the unibond ready mixed anti mould and get either a Bal ready mixed ady which i take it will stick to green moisture board without a problem and not need primed and seperate grout?

If you want to use ready mix, then White Star is brilliant stuff. You will still need to wait until the next day to grout though....and make sure you use a "proper" grout...don't grout with the White Star....
