Maintaining the Caulk on a Granite Kitchen Sink Undermount Christopher Anzalone Updated on 02 February 2022 A granite undermount sink can add tremendous style and sophistication to a kitchen. The fully enclosed sink basin, surrounded by natural stone, has a significantly more streamlined appearance than conventional drop-in sinks.

Most undermount sinks are caulked to prevent water from leaking between the sink and the countertop. It is essential that you maintain this caulking properly so as not to compromise the seal. Always hold the caulking gun at a 45-degree angle when applying new caulk, and attempt to apply the layer in a single, uninterrupted stream.

Apply new caulking when the temperature is neither too hot nor too cold for optimal results.

  1. Circulate air throughout your kitchen. Increasing air circulation is as simple as opening a window for a few hours per day, using fans, or turning on the central heating system. Proper air circulation helps to regulate the room’s moisture and humidity, which is essential because excess water vapor can penetrate caulking and cause it to crack.
  2. After using your sink, wipe your caulking with a dry, clean cloth or towel. This will further prevent moisture from penetrating the seal and maintain the cleanliness of the caulking. If the caulking becomes extremely dirty, lightly scrub it with a mineral spirits-dampened cloth. Mineral spirits are available in home improvement stores. Mineral spirits are solvent-based and pH-neutral, so they should not be harmful to granite. However, test them first in an inconspicuous area, and if necessary, cover the granite with painter’s tape.
  3. Regularly inspect the caulking for signs of cracking. Using a putty knife or screwdriver, remove the existing caulk if you notice cracks. Remove the remnants and vacuum the joint using a handheld vacuum or hose. Apply a new layer of caulk to the joint and cover the surrounding granite and sink with painter’s tape. For kitchen fixtures such as sinks, silicone caulk is recommended.
