Shower Plug

Fix a leaking shower with one DIY application.

Shower Plug is a clear, brush-on solution that repels water from tiled surfaces.

This makes it ideal for: fixing and preventing leaks through tiles and grout, preventing mould growth and making the tiles and grout easier to clean. This will work both indoors and outdoors, so both showers and balconies can be treated with Shower Plug.

Leaks occur when water seeps through the tiles and grout, whether they are cracked or not. Fixing that problem is simple: brush Shower Plug on and it's waterproof, ready to use in 12 hours, and will remain that way for over ten years. Shower Plug will not change the surface appearance or texture.

The Shower Plug Solution

When brushed on, Shower Plug penetrates the substrate and chemically bonds with it. Within 18 hours, Shower Plug forms an invisible, hydrophobic barrier that lasts for up to ten years. Instead of soaking in, water beads and runs off; totally preventing water from seeping through the surface.

We demonstrate how to apply Shower Plug to fix a leaking shower.

Preparation: repair

First of all, if there are any cracks in the tiles and grout greater than a hairline, they must be repaired using regular superfine grout. Allow the repair grout to dry for 24 hours.

Any cracks less than a hairline will be sealed by Shower Plug alone.

Clean any mould using bleach.

Application of Shower Plug: the two-coat process

  1. Using a natural-bristle brush, apply one coat covering all surface area evenly with a layer of Shower Plug.
  2. Wait five minutes and repeat.
  3. Wait five minutes and then wipe away any excess.

A tip for vertical surfaces:
Begin the two-coat process at the top of the wall and work down to the floor. Complete the walls first and then begin the two-coat process on the floor.

After application of Shower Plug

Water repellency will develop after the surface is dry. Full curing will take 12 hours. Therefore, the surface should only be exposed to water after 12 hours.

Finally, it is advisable to apply a silicone strip between the wall and floor joint after applying Shower Plug. This is because building movement is known to cause cracking in the joints.

Handling and Storage

Follow good industrial hygiene procedures. Vapour inhalation and skin or eye contact should be avoided. Therefore, we recommend gloves, goggles and an air filter mask. Wash hands after handling. Store in a closed container in a cool dry, place away from any fire and ignition sources. Shower Plug has a shelf life of up to five years in a sealed container under 25°C.
