How-To: Bathroom Waterproofing

Shower Plug's advanced chemistry not only provides long-term results, but it also does the hard work for you.

Using a natural bristle brush, apply two coats of Shower Plug, five minutes apart, and then wipe away the remaining excess five minutes after the second coat.

Job done, without removing tiles.

Application Notes for Shower Plug

Shower Plug’s formulation is high quality and therefore very safe to use. Nevertheless, it is always advisable to use protective gear and ventilation when applying the product.

Shower Plug does not change the surface texture or appearance. Remember to wipe the final coat off within five minutes. If Shower Plug is left to dry out on the surface, a white residue will remain. Remove this with turpentine.

Shower Plug will give off a solvent-type odour as it is is applied and as it cures. This odour will fade by the end of the curing process.

Shower Plug does not affect clothing.

Shower Plug is suitable for use on:


Tiles, including: ceramic, porcelain, marble, glazed or unglazed, terrazzo, slate, terracotta, and others.
