Anyone with basic painting skills can use UltraCare Grout Refresh. The UltraCare Grout Refresh bottle has a cone-shaped applicator tip that easily directs the sealant to the grout joint. All it takes is a toothbrush or similar nylon brush to spread UltraCare Grout Refresh over the grout, and a bucket of clean water and a clean, damp sponge to remove the excess.
