How to Caulk a Stainless Steel Sink on Tile
- Nov 05, 2018 -

When sealing a stainless steel sink to a tile countertop, there are two main things to consider: the best type of caulk and where to put it. Not all caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/Silicone sealant/Potting silicone sealant/Huitian adhesive/Huitian silicone/Huitian sealant/flange sealant/conductive sealant/Electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive/gasker maker/thread locker/Thread adhesive) sticks to metal and tile, so use a silicone caulk, which sticks to both and creates a water barrier. Tile isn't a solid, flat surface like granite or laminate, so it requires two lines of caulk to make sure no water can seep under the sink through the grout lines, which are usually lower than the tile level.


Cut a line down existing caulk to break the seal with a utility knife, then peel it away from the sink and tile counter. Scrape remaining caulk with a utility knife or razor blade tool.


2

Wash the area where the sink meets the tile with warm water and a mild detergent. Allow the area to dry.


3

Cut the tip off a tube of silicone caulk at a 45-degree angle using a utility knife. Clear caulk is the best option for this job as a colored caulk is unlikely to match all three elements: the sink, the tile and the grout. Place the base of the caulk tube into the back of a caulk gun and rest the tip into the notch at the front of the gun. Pierce the seal inside the tip with a long nail, then squeeze the trigger until caulk appears. Wipe away the caulk with a rag.


4

Lift the sink away from the counter by at least 2 inches; the sink must be high enough for you to fit the nozzle of the caulk tube underneath. Have a helper hold the sink for you.


5

Slide the nozzle under the sink so that it touches the tile where the perimeter of the sink will sit. Squeeze the trigger with steady pressure as you move the caulk gun on the tile around the sink, following the line of the sink's overhang. Lay an even bead of caulk all the way around the sink.


6

Lower the sink into place on top of the caulk bead. Wipe away any that oozes out from under the sink overhang with a rag or a wet finger.


7

Lay a bead of caulk on the outside edge of the sink where it meets the tile. Wipe away excess caulk with a wet finger, flattening the bead.

  • Nail

Tips

  • Although caulking under the sink may seem unnecessary, it helps fill in the gaps between the grout and the sink. Caulking only the outside edge of the sink could allow water to penetrate the seal along the lower edges of the grout lines.

  • Better-quality caulk (acrylic silicone/acrylic sealant/silicone/sealant/adhesive/potting sealant/potting adhesive/potting compound/UV glue/Silicone sealant/Potting silicone sealant/Huitian adhesive/Huitian silicone/Huitian sealant/flange sealant/conductive sealant/Electrical sealant/electronic adhesive/epoxy sealant/epoxy adhesive/PU adhesive/gasker maker/thread locker/Thread adhesive) guns have a control on the trigger or at the back to allow you to release pressure on the caulk tube, so that the caulk doesn't continue to flow after you've stopped pulling the trigger.
