Color the caulk with grout

Photo 1: Use grout to color-match the caulk

Squeeze caulk onto a mixing board, making sure you use enough to complete the entire job (it’ll be hard to match if you have to add more later). Then add colored grout to the caulk and mix thoroughly with a 3-in. putty knife.

If you’ve checked out the sanded caulk near the grout in the tile department and can’t find one to match your tile project, just follow these two steps. First add the colored grout to a large blob of fresh caulk and mix it in (Photo 1).

Tape off the caulking area and apply the mixture

Photo 2: It’s like decorating a cake!

Scoop a hefty portion into a zip-top freezer bag. Zip the top shut and snip off one bottom corner. Then apply the caulk/grout bead to your tub and tool the joint with a plastic spoon or wet finger. Pull the tape free before the caulk sets up.

Once you’ve mixed in enough grout to match your existing grout, load the grout/colored caulk mix into a zip-top bag and apply it (Photo 2).
