Uses
Forever White Grout Reviver by Everbuild is an excellent product that utilises the Mould Shield formula developed to combat all forms of organic growth and restore old grout to a pristine condition. It contains high-quality antimicrobial properties, which have been rigorously tested in accredited microbiological laboratories to show no organic growth after 10 years!
Preparation
Before starting the application, you must prepare the surface, remove any present mould, and ensure it's clean and dry and free from dirt and grime. Replace any damaged, loose or cracked grouting by raking and re-grouting and allow it to dry. This product isn't suitable for particular tiles, such as; non-glazed, metallic, textured or hand-painted; it is suggested to test its suitability before commencing the entire application.
Application
Remove the cap and squeeze the product applying it directly to grout lines in a zig-zag motion ensuring even coverage and working it well into the existing grout.
Allow it to dry for 3-4 hours, then remove any excess product from tiles with a damp cloth or sponge; any residue that sticks needs to be slightly moistened and left for 15 minutes. Afterwards, it will then wipe away.
A second application may be needed for badly stained areas; complete this after the first coat has dried completely.
After the application, polish the tiles with a clean, dry cloth and avoid wetting them for 24 hours to allow the product to work fully.
