What to use to fill the joint between the back of my sink and the wall tile?
QUESTION
What do I use to fill the joint between the back of my sink and the wall tile? - Four years ago I had granite countertops installed and put ceramic tile backsplash. The grout behind the faucet is constantly getting gummy and comes out but everywhere else it is fine. I did not seal it. I eventually pulled it out behind the faucet and put acyrlic caulking and that does the same thing. Can you offer any solutions?ANSWER
ANSWER - I am assuming that when you refer to the grout behind the faucet, it is the transition joint from the granite countertop to the tile wall back splash. This joint should be a movement joint filled with a proper flexible sealant.If the material in that joint becomes gummy then it was probably a cheap caulking/sealant that was originally used. The acrylic caulking is also considered a cheap sealant that doesn't meet the industry standards requirement. If the product says siliconized sealant it also doesn't meet the standards and won't perform as well as the industry standard requirement of an ASTM C920 sealant. ASTM C920 sealants are normally either a pure silicone sealant or a urethane sealant. They are messier to use, but they last a lot longer and perform a lot better.
Make sure you follow the instruction on how to use the sealant. Remove the old sealant and clean the joint thoroughly. Apply blue masking tape on either side of the joint prior to filling it. Immediately scrap excess off and pull masking tape within 5 minutes or the tape will tend to pull the sealant out with it. Good luck!
