This article provides a method to seal grout without having to get on your hands and knees. The main idea is to use a brush with a long handle to apply the sealer instead of doing it manually. The process involves pouring the sealer into a paint tray, dipping the brush into the tray, and then using the brush to apply the sealer onto the grout lines. This allows for a more convenient and comfortable way to seal grout without the need for excessive bending and kneeling.
