joint mortar
Application 1. Mix CRISTALLFUGE-FLEX with clean water in a clean mixing bucket. Add 4.0-5.0 l water depending on the desired consistency, add 25 kg CRISTALLFUGE-FLEX, and then stir into a homogeneous, smooth compound. We recommend mixing with a suitable stirrer. After an activation time of 4 min., the joint mortar is stirred again. In order to avoid colour differences, the mix ratio must always be kept the same. 2. CRISTALLFUGE-FLEX is added to the wall and floor areas with a suitable jointing board and pulled diagonally to the joint cleanly, so that the joint cross-section is filled completely. Do not scatter dry joint mortar powder. 3. After applying the joint mortar (control via finger test), wash the surface first with a moist sponge board. After approx. 10-15 minutes, wash off again with the sponge board. Please refer to the currently valid technical data sheet for additional instructions.
High-strength flex joint mortar, 3–20 mm, CG2 W A Properties • Rapid setting • Good binding and wash-off properties • 3 - 20 mm joint width, curing without cracks • For porcelain stoneware and many other coverings • Water-repellent • Frost/thaw-resistant • Suitable for floor and wall heating systems • Colours matched to the ESCOSIL-2000 and ESCOSIL-2000-ST silicone system • Fulfils AgBB formula requirements. Areas of use • CRISTALLFUGE-FLEX is suitable for grouting porcelain stoneware, vitrified tiles and stoneware boards, brick tiles, artificial stone, facing bricks, veneer and floor bricks in baths, showers, and living areas, on terraces, balconies and loggias, and façades, in swimming pools, commercial and industrial facilities, as well as heating flow screeds for joint widths from 3–20 mm. • CRISTALLFUGE-FLEX is also suitable for grouting many natural stones.
Application • After the bedding mortar/tile adhesive sets, scratch out the joints sufficiently deep. • Next, clean the tiled finish sufficiently damp. • The bedding mortar must be fully set, since otherwise discolourations in the grout finish could result. • Pre-moisten strongly absorbing coverings with water equally. • Joint edges must be clean and free of separating substances. • The time of grouting of the tiles set in the thin-bed depends on the thinbed mortar and amounts to approx. 3 to 72 hours. In case of thick-bed laying, the mortar bed must be sufficiently firm and equally dry. • Do not grout on surfaces with different surfaces temperatures (e.g. due to sun exposure). • The consistency of joint mortar must be specified depending on the absorbency of the covering and substrate to be grouted.
