Attachment to a timber or metal frame

Preparing the installation surface or frame

The rabbet edged Tulppa panels are designed to be installed horizontally with an on-center stud spacing of 600 mm. The Tulppa panels’ innovative, patented joint solution and installation system make installation significantly faster and easier. The concealed attachment at the edge using Tulppa Z brackets and the rabbeted solution combined with a sealing adhesive compound ensure safe, waterproof joints in one working stage.

For fittings and bathroom furnishings, mounting planks are installed on to the framework (support strips or plywood). Lightweight fixtures, such as towel hooks and toilet paper holders, may be attached on to the surface of the tiling using Kiilto XPU adhesive sealant.

Attachment to the base

The actual installation begins with the application of a 1–2 mm wide line of Kiilto XPU adhesive sealant on each frame beam behind the panel, including the support strips.

The lowest Tulppa panel on the wall is placed on top of wedges and pressed on to the frame. During installation, ensure that the back side of the panel placed against the studding is higher than the front side, i.e. the rabbeting is placed the right way up. It is not necessary to saw off the rabbeting on the long side of the Tulppa panel placed against the ground. This is done to leave sufficient space for the sealing compound applied to the joint.

Panel seams and corner joints

At the corners, a gap of 1–3 mm is left between the panels to be filled in with Kiilto XPU adhesive sealant. The gap must be filled in thoroughly up to the surface of the panel. The panels are pressed firmly together, and any excess adhesive paste is smoothed over the joint using a trowel.

Once the adhesive compound is surface dry, the corners and the intersection of the floor and the wall are sealed using Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane and Kiilto Nurkkavahvike tape. Ensure that no air pockets are left under the reinforcement tape pressed on top of the fresh layer of waterproofing. It is not necessary to separately waterproof the horizontal seams. Any vertical seams are waterproofed in the same manner as corners, but it is not necessary to waterproof the horizontal seams between the panels according to the system.

Wall and floor joint

Concrete floor of a wet room is waterproofed according to Kiilto’s work instructions. The gap between the Tulppa panel and the floor is filled in with Kiilto XPU adhesive sealant and any excess compound is smoothed over the surface of the panel (please note that the waterproofing membrane brought up from the floor must adhere to 30–50 mm of the surface of a clean Tulppa panel). The waterproofing membrane applied to the floor is brought at least 100 mm up the wall, which means that it will also cover the Tulppa O brackets used near the floor level. Kiilto Nurkkavahvike tape is pressed on to a fresh coat of Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane such that no air pockets are left between the tape and the below surface. Kiilto Nurkkavahvike tape is completely covered with Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane.

Passages

The gaps between passages and Tulppa panels are sealed during the attachment of the panels using Kiilto XPU adhesive sealant. Pipe inlets are sealed once the adhesive sealant has dried using Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane and Kiilto Läpivientivahvike reinforcement sheets. During sealing, you must ensure that no dried-up excess installation adhesive is left between the pipe cuff and the pipe.

Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane is spread around the pipe to cover the area on to which the Kiilto Läpivientivahvike pipe inlet reinforcement sheet is placed. The Kiilto Läpivientivahvike reinforcement sheet is laid on top of a fresh coat of Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane and rubbed smooth to push out any air below the cuff. Finally, Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane is used to cover the Kiilto Läpivientivahvike reinforcement sheet, which must also extend over the collar on to the surface of the Tulppa panel.

Tiling

You can begin tiling once the Kiilto Kerafiber or Kiilto Keramix A+X waterproofing membrane is dry. The drying will usually take 2–24 hours depending on the products and conditions, thickness of the layers, temperature, and the relative humidity of air. It is important to wipe the surfaces of the panels clean from dust and dirt with a moist cloth. Before you begin the installation, use a wet sponge to moisten the surface of the wall. Tiles are adhered with Kiilto Superfix DF or Kiilto Highflex S2 DF tiling adhesive. The tiles are grouted using Kiilto Saumalaasti tile grout and the corners are filled in with Kiilto Saniteettisilikoni.
