We recommend fixing plaster coving with both screws and adhesive and never to rely on adhesive alone for fixing coving. We have installation video guides on the website and also a guide showing how to mix coving adhesive to the right consistency. 25kg of coving adhesive will be enough for 50m of coving, though this will vary with the size of the coving and if you put more on than is necessary (which will not do any harm), it will not go as far.
This product is only available to purchase along with coving orders at checkout. We cannot supply this product on its own.
