Technotape/Dilatape or equivalent).If the wall areas differ from eachother on either side, the joint mustpreviously be evened out with a thinlayer of plaster. This plaster must behardened out before the self-adhesivefibreglass tape is applied.Filled movement joints can remainvisible finishing the layer of plasterwith a casing bead on both sides ofthe movement joint. It is importantthat the casing beads are kept atleast 3 mm apart and filled with anairtight and flexible seal, which willremain flexible and can be painted.“Cold” movement joints in a wall witha layer of plaster, over which a nonelasticlayer of paint is applied, canbe finished off with 2 casing beadswith 1 to 2 mm space, with a hiddenelastic seal.SILKA Calcium Silicate Elements27
