Application

YAPIFINE MEND EPOXY 2C applied on both sides of the dilation approximately 1-1.5 mm thickness and 40-50 mm width by trowel or spatula. In order to ensure good adhesion the adhesive should be applied really well onto the surface. The areas where tape application will be done are determined and the tape sizes are adjusted accordingly. The dilatation band is placed onto its adhesive side and with the help of a roller, it is made sure that the band makes thorough contact with the epoxy mortar. The mortar is observed to be coming out of the holes on the band. Likewise, the epoxy mortar is applied on the top side of the band as well. With the help fo a spatula the mortar is smoothed and evened out all the while paying attention that the mortar does not cross over into the joint space. In case there will be additional band applications, the bands are placed such that the overlap length between them is 10 cm. Hot air is blown onto the overlapping parts so that they melt and are melded together. During this process, it is recommended to use low temperatures just enough to melt the bands and meld them together in order to avoid deforming the bands. The bands shouldn’t be moved or lifted up until the adhesive mortar has thoroughly dried and hardened.
