A handyman suggested to me that I might need to periodically apply water-sealant to the tile and grout on the tile wall of my bathtub. Is he correct?

If so, what's a good sealant to use, how is it best applied, and how often should I re-apply it? (It's probably been 15 years since the previous owner refinished this bathroom and put in a tile wall, so probably been 15 years since any sealing was done.)

After a good cleaning, (Tris-odium Phosphate and a stiff brush), Apply generic furniture lemon oil. Wipe off excess. I have been setting tile for years and this works wonders.


The short answer to this question is yes. It never hurts to have sealer on your grout. Especially in wet areas. I've never used lemon oil though. A good water based sealer generally does the trick. Check the particular sealer you buy to see how often you need to re-apply it. It varies from manufacturer and quality of sealer used.
