Seal the shower - explained in logical order

Required materials:

  • quick hardening mortar
  • Primer for wet rooms, brush or roller
  • abrasive paper
  • sealing paint
  • Roller or brush for distribution
  • Fabric tape for sealing

Step 1

To seal your shower, you must first prepare the surface accordingly. First, remove dust, dirt, and offensive particles from the floor and walls. Since the sealant should be applied in the entire spray and wet area, a cleaning of the walls is also necessary. You can close holes and cracks with the quick-hardening mortar. If you notice bumps, remove them thoroughly with the sandpaper. Let the mortar dry well. It is particularly important that you keep the surface completely free of grease and oil. Only then can the sealant be applied correctly and is permanently impermeable to water.

step 2

In the next step to seal your shower, apply the primer. You can do this with a small spot brush or a large area roll. The primer ensures that different suction behavior of the substrate is compensated. This creates an ideal base for the sealing coat, which can be evenly applied in all places. The primer must dry for a few hours, pay attention to the manufacturer's instructions.

step 3

After completely drying the primer, start applying the sealant. To completely and safely seal your shower, you will need at least two coats here. Apply the sealant evenly on the walls and floor of the shower with a roller or brush. Once this step has been taken, the fabric tape is inserted. The tape is intended for corners and edges and should create a seamless transition between the walls and the walls and the floor. Simply place the cut-to-size fabric tape in the still-moist seal coat and lightly press it so that there are no air bubbles or wrinkles. After the first coat has dried, coat the applied fabric tape with the second coat of paint. So there are flowing transitions. With connections recessed in wall or floor, proceed similarly. The connections are edged with fabric tape and overcoated with the second coat.

Step 4

After the sealant has dried sufficiently long, you can start dressing the wall and floor. The dry phase of the seal coat usually takes 10 to 12 hours. How to reliably seal your shower!
