What is Shower Plug?


Shower Plug is an invisible, brush-on sealer that repels water from masonry surfaces.

  • Fixing and preventing leaks through tiles and grout (without removing them)
  • Mould prevention
  • Preventing efflorescence on tiles and walls
  • Making the tiles and grout easier to clean

The Shower Plug product is a 100% UV resistant waterproof sealant that can be used indoors and outdoors. Use it as a DIY solution to waterproof new and existing showers, bathrooms, balconies, driveways and building facades.

How Shower Plug Works

Shower Plug is a penetrating waterproof sealant. When applied, it penetrates the substrate surface to a depth of 2-5mm and chemically bonds with the sand-cement particles on a molecular level. It forms an invisible, hydrophobic barrier that causes water to bead and run off the surface. This water-repellency lasts for a minimum of 10 years.

The Shower Waterproofing Solution, Explained

Leaks occur when water finds a way through porous tiles and grout, either through a break in the surface or by simply soaking through. The membrane below is designed to catch the water, but membranes are prone to failure through multiple causes. When the membrane fails, structural damage will result from the unchecked water leak.

To fix or prevent a leak, the surface needs to be treated with Shower Plug. Shower Plug is a liquid treatment that will soak into the porous surface and make it totally waterproof.

After the brush-on treatment, the surface will be ready to use within 18 hours. No tiles are removed, and the surface appearance and texture will not be changed. The membrane below becomes redundant, and any trapped water remaining below the surface will evaporate.

Shower Plug will protect any masonry surface from all forms of water damage, including: efflorescence, mould, algae, discolouration, erosion and concrete cancer.

1. Preparation: Repair Cracks in Tiles and Grout

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 dirt and mould using bleach then allow to dry.

2. Application of Shower Plug: The Two-Coat Process

  • Apply an even coat of Shower Plug covering the entire surface area, starting on the walls.*
  • Wait 5 mins and then repeat this process.
  • Wait another 5 mins 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 shower floor. Complete the shower walls first and then begin the two-coat process on the floor.

3. After application of Shower Plug

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

Frequently Asked Questions About Shower Plug

What is the difference between Shower Plug and other bathroom sealants?

Shower Plug is an impregnant, which is essentially a chemical treatment for masonry rather than a coating or a membrane. Shower Plug soaks into the masonry to chemically bond with it on a molecular level. No part of the treatment will sit above the surface, unlike coating-type waterproof systems.

The advantage of this is:
– it cannot fail due to physical wear and tear
– it will not change the surface appearance or safety.

Due to its advanced formulation, Shower Plug allows the surface to ‘breathe’ by allowing trapped water to escape through evaporation. Coatings, membranes and many sealants are not breathable.

Shower Plug also prevents mould growth by denying it a damp surface to live on. Coating-type sealers do not achieve this and so mould remains an issue.

When can I use the shower after the shower leak repair process?

Wait 12 hours for the shower seal to completely cure.

How do I maintain the surface after completing the shower waterproofing process?

You can use your usual cleaning products. Shower Plug will not be affected by any cleaning methods.

Where can I buy Shower Plug?

Australian customers can visit a local Bunnings Warehouse in the flooring section, or buy Shower Plug from our secure online shop. We ship across Australia and internationally.

Silicone Strips – do I brush Shower Plug over the silicone strip?
If Shower Plug comes into contact with a silicone strip, the silicone will soften and then re-harden as it dries. Therefore, we recommend either:
1. Protecting existing silicone with masking tape and avoiding it as you apply Shower Plug
2. If the silicone strip is worn out, remove it, apply Shower Plug and replace it.
Will Shower Plug work over terrazzo or crazed tiles?
Shower Plug will work if the crack or craze is no greater than a hairline. Any cracks greater than that will need to be patched up with grout.
