We recommend only filling joints with casting plaster. Not only is casting plaster better, it costs less than filler too. If you have not used it before please have look at the video on this page which shows how to mix it and how long to wait before it is ready for use. A 25kg bag will be enough for filling at least 150m of plaster coving, depending on the size of coving.
This product is only available to purchase along with coving orders at checkout. We cannot supply this product on its own.
