    There is the product extratime not used it myself.

    Happens to us all at times, it just depends on the suction.

    The obvious though is to be a bit quicker, how long is it taking you to apply the 1st cost ?

    Pack up plastering if you can't keep on top of a 20m2 lid!

    Use extratime but I would look at your technique and see where you can streamline the operation :D

    Lay half on and drop back and flatten then other half.....but you should really be able to keep up with 20sqm unless its really high suction....if suction was the problem more PVA until you've killed it....what ratio you use for pva

    buy extratime (think it is £2 for sachet) that will give you the time you need... Then when you are use to it you can go and buy C of T if you like and work it out yourself

    Tbh I never use PVA diluted any more than 50/50

    I know its stated 5/1 followed by 3/1

    But tbh 50/50 then leave to dry IMO holds off suction far more!

    Had a 20odd m2 a while back that was giving me the run around if you actually let the pva fully dry out and cure it holds it back much better then say same day.

    I do dilute it down 3-4:1 for things that are high suction but you do need to give it another coat of something stronger after. And tbh it's not like 1:1 has ever failed me

    I always put a weak coat of pva on first so it soaks in I find if I put a really strong mix of pva on it just lays on the top

    Just like painting really .... first coat is normally watered down on sucky surfaces.

    What was the background?

    Sounds like it is your background sucking up , as other peeps have said control your suction
    If it is plasterboard search for rolling set on plasterers forum

    Tip the 5ltr tub of uni in a bucket then fill the empty uni tub with water and put that into the bucket with the uni in, there you have it a 50/50 mix and I'll give you that info for free

    Problem with 50/50 pva is some brands are like coloured water to start with. You should know yourself the consistency when you water it down by mixing it and you can change the mix ratio depending what your doing.

    Tbf I think with PVA you should buy what you know and trust and stuck with it at the ratio you trust!

    Wickes own brand does me fine 1 tub @50/50 over any background leave to dry and bobs yer uncle!
