Mastic Sealant

Newton 800 Mastic is used with Newton 805 Newlath, Newton 503 and Newton 803 Newtonite. It is applied to the plug before fixing into the membrane, which serves to stop any ‘bridge’ happening between the damp or stained surface and the new surface. Newton Mastic is also used for sealing around protrusions.
