How-To: Bathroom Waterproofing

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 odor as it is is applied and as it cures. This odor will fade by the end of the curing process.

Shower Plug does not affect clothing.
