Overview

Tiles and grout can be porous, so waterproofing them is key to bathroom maintenance. Our method using Shower Plug is ideal for fixing leaking showers or preventing leaks from occurring in new showers.

Steps

1Clean your shower

It's important to remove all dirt and mould from your tiles and grout for a smooth application. Give your shower a good scrub and wait for it to dry.

2 Mask off glass, silicone, metal or plastic edges

Use masking tape to protect any silicone strips, glass walls and taps from Shower Plug. We want to keep these features free of any product build up. 

3Safety first

Be sure to open a window or door for ventilation and put on your protective gloves and mask.

4Apply Shower Plug to the walls of your shower

Using a natural bristle brush, paint a coat of Shower Plug onto the walls of your shower and wait five minutes before applying a second coat. Apply the second coat and wait another five minutes. Now wipe any excess product off using an absorbent cloth.

Tip: Any spills or equipment can be cleaned by wiping off with a cloth, or by using methylated spirits.

5Repeat the process for the floor of your shower

Now we'll seal the floor of the shower. Using the same brush, paint the first coat of Shower Plug onto the floor of your shower. Wait five minutes before painting a second coat. Apply the second coat and wait another five minutes. Now wipe off any excess product with an absorbent cloth.

6Seal between the wall and floor joint

To complete the project and prevent any cracks caused by building movement, apply a silicone joint sealant along the wall and floor joint. For more advice, watch our video on how to apply bathroom sealant

7Wait for the Shower Plug to set

You'll need to wait 12 hours from the last application for Shower Plug to cure. The product will dry to an invisible finish.

8Reap the benefits

Once the product has cured, your shower is ready for use. It will now be easier to clean, resistant to mould and repel any water from the tiled surface.

9More great uses

Put your left-over Shower Plug to use by tackling a tiled balcony in need of waterproofing.
