Everbuild SBR Bond as primer

[Perry]

I think BAL will say you do need to prime as they say the adhesive can migrate through the boards.

bal are a profit making company they care more about making money than you or I

i agree with both of you.....they will always look for a way out.

I'm against priming plasterboard, almost seems like you're putting too much moisture into it.

I thought Plasterboard HAD to be primed if using a cement based addy because of Ettringite failure?

you are tiling the paper not the plaster

Never did tiling before, just having a go mate.
Gave the bitumen a good neat coat of Bal SBR Bond, still a bit tacky, also were no bitumen on concrete also still tacky almost two days later, almost dry.

If I was to give Floor Vinyl Tiles, Concrete, Old Bitumen adhesive left over from removing tiles,two coats of SBR neat will it take the floor Tiles better.
Thanks Mate.

Haha Very true! Is the paper enough to stop a reaction then? I really can't afford to be forgetting what little i do know!?!?! :lol:

where you wanting this post Derwent? it's in two threads now, I can delete one if you like

Sorry to bring up an ancient thread! But I'm about to tile a bar concrete floor and don't know whether I need to prime it or not. I happen to have some Everbuild 503 SBR left from a garden paving project, so when i found this thread I thought it could be handy to know if this would work?

Do I need to prime bare concrete (rough finished, not machined, and never been tiled on before, it's been laid a year but only just getting round to tiling)

If so, do I need to use it neat, dilute it, make a slurry with cement? And how long will it take to dry?

Thanks!
