Grout is a construction material used to seal the spaces between tiles or concrete. Grout is typically made from cement, water, sand, and added colour. Grout is added once tiles have been installed, then whatever excess grout there is gets wiped away. Grout is applied in liquid form, and then hardens over time.
If you want your grout lines to remain fresh and crisp and their original colour then yes. Many manufacturers will say it's an unnecessary expense but when you are down on your knees scrubbing the grout lines you will wish you had them sealed. It will also increase the lifetime of the grout, particularly in wet and outdoor areas.
Essentially no. A "grout only" seal should be applied with a penetrating sealer as a topical seal(or surface sealer) will flake and the area will look ununiformed. If you seal the entire tiled area with a topical sealer then that will adhere to the grout better.
Although a sealer will make the grout easier to maintain it doesn't act as force field for dirt and grime. Regular maintenance is necessary to make sure your grout remains fresh.
