Aquapanel exterior

Anyone familiar with aquapanel exterior, I've fixed some to my own house and the joints which I filled with joint cement and tape have got fine hair line cracks just wondering if the this will pull through on my thin coat render system ???

@runwithscissors is you tech guy. But i cant see why you leave a gap in boards for movement to fill it with a hard filler. Surely losing the expansion. Ability

Just following what knauf recommend mate which is a 5 to 3 mm gap

And your right to follow spec. You know there no comebacks on you then

Hi Wil

Thanks for the message bud - I have a little experience of Knauf Aquapanel Exterior......

Cracks are usually a result of movement in the structure behind - if you have a timber frame behind, in the first 12 months (especially during construction) it will settle and this is when any cracking will happen. Initially, I will say it is nothing to worry about - the gap between the boards, the flexible joint filler and tape then the basecoat and mesh will all disipate the potential of cracking in the finish render.

Give me a call on Monday - 07918766577 - and we will have a chat about your build. If you have some photos of your build and the cracks, send them to be at rlord@knauf.co.uk

Best Wishes
