The professional sealing of the floor- and wall areas that should be tiled had to work fastly and reliable. Due to its very fast construction progress and the high safety promise, the water resistant and crack-bridging sealing and decoupling membrane codex Hydrostop was used. It consists out of a Polyethylene sheet with fleece fabric applied on both sides – ready for laying due to a printed cutting grid – and is easy to apply. The material has very low emissions, suitable for healthy housing construction and it suits the reliable sealing of moist-stressed substrates in shower installations in residential, commercial and industrial areas. Codex Hydrostop, which is available in 100 and 140 cm width, reaches the water impact classes W0-I, W1-I and W2-I according to DIN 18534. The sealing membrane became glued onto the substrate with a fast and flexible thin- and fluid-bed mortar codex Power RX 6 Turbo. It enabled further working steps after already 2 ½ hours. The joints and the connections to drains, gutters and penetrations were sealed with the matching codex sealing tapes, wall collars and sealing corners in combination with the fast-setting 1-component flex sealing compound codex AX 230. Joints were bonded with the 1-component hybrid sealing and assembly adhesive codex SK 100.
The planned large format tiles in the spa- and shower area were laid with the proven large-format adhesive codex RX 8, which is a highly flexible thin- and flow-bed adhesive with crystalline water retention. The remaining areas were laid with the lightweight multi-purpose flexible adhesive codex Power CX 7.
When using the cementitious grout mortar codex Resist, it was important that the grout can withstand the mechanical stresses through a high frequency of cleaning in the long term. It contains highest resistance against abrasion and dries quickly even at low temperatures.
