How do I make my backsplash more waterproof?

I have tile around my kitchen sink and water splashes from faucet/sprayer and it gets yucky with mold and slime. I re-grouted the tile but the same problem exists with the water between back splash and kitchen sink. he sink is not recessed so a pool or stream forms almost every time I use the sink. Any suggestions?Sandy

  • Only way to combat that is to wipe down with a kitchen towel after each use and clean regularly.

    I bet that if your kitchen faucet spout were to discharge water beyond your sink's midpoint, or directly over the strainer, you would have less splashing.

    If the sprayer is used lower in the sink, with less water pressure,

    splashing is reduced.

    You may want to apply a heavy layer of car wax behind the sink. Wipe dry after using sink, as suggested. Clean regularly with a rag soaked in distilled white vinegar, so long as your surfaces are not stone.

      Hi, Sandra,

      I think I found your answer at:

      The answer may be replacing your faucet aerator with a special order laminar insert that prevents the splash. Check out the article to see what you think.

    Use a grout sealer on the grout. Spray some plain canola cooking oil on a cloth and rub it on the tile. Will repel the water.

      William, thanks for taking the time to reply. I keep a rolled kitchen towel rolled between the faucet and back splash to try to keep it dry. I use the sink so often that it always seems wet. I have a small fan on it to try to dry the new grout. I will seal it again, and try clear silicone, if I ever get it dry long enough! Will also put the canola oil on it. Thanks again!

    Maybe the towel is the problem. I would think it would keep the area damp. I think your idea of clear silicon is a good one. Fill the entire area with it slopping out to the sides. Also there is a caulk that can be applied in wet conditions, even outdoors in rain.
