Does external render peel-off (delaminate) from the Dincel surface?

No - Dincel panel joints control and minimise the contraction and expansion movements of the wall surface. Any differential movement between the Dincel skin and applied render finish is significantly reduced in comparison to conventional walls. The etching primer prepares the Dincel surface for chemical bonding. The polymer render base coat, being flexible enough, also absorbs any possible movement differential at the matching surfaces. In fact, this combination becomes much more reliable than the conventional cement render applied to masonry, concrete or fibre-cement surfaces. Dincel is recognised by the leading render suppliers who have specifications for their render finishes to be used on Dincel PVC skin.
