Colored Caulking

Did you know that you can get acrylic and silicone caulking that matches the color of your grout?


Colored caulking is useful for backsplashes, tiled showers, or in any installation where you need a flexible seam of a particular hue.


We stock over 40 different colors of caulking designed to match the color and texture of grout. We can also order caulking that matches several popular grout brands such as Custom Building Products, Laticrete, Mapei, TEC, and Bostik.  

When (and why) do I need to use caulking?

Inside Corners for added Flexibility

Cracked grout between glass bubble mosaics and porcelain tiles.
Grout can crack and separate from tile, while caulk remains flexible. This inside corner should have been caulked to prevent these cracks.

The Tile Council of North America recommends that you use caulk instead of grout on any inside corners. Where your backsplash meets your countertop, where your shower walls meet your bathtub, where your tile baseboard meets your tile floor, where one tiled wall meets another tiled wall, use caulking.


When two planes meet in a house (wall meets floor, wall meets wall), there will be flex and movement. Even the sturdiest house has some movement. If grout is installed in these corners, there is a chance it will crack or separate from the tiles, allowing moisture or dirt to get through and creating a shoddy look.


Caulk remains flexible when installed, while cement-based grout is very brittle and epoxy grout is not very flexible. 


With highly flexible grouts such as urethane and single-component grout, you have the option of forgoing caulk and using the grout your inside corners. However, these grouts are not as pliable as caulking.

Finishing Edges

Caulking the edge of a backsplash

You can also use caulking at the edge of your tile installation to hide the unfinished edge of your tile. Caulking is the least expensive finishing option (short of leaving the edge bare), and is a simple alternative to bullnose tile, pencil liners, or metal edging.

Siliconized Acrylic and 100% Silicone Caulking

What's the difference?

Simply put, 100% silicone caulking should be used to caulk showers, and siliconized acrylic caulking should be used everywhere else.


Siliconized acrylic caulking is less expensive, easier to clean up, and better matches the texture and look of your grout; but 100% silicone caulking lasts much longer in wet areas.


In areas that might get water splashed upon them, such as kitchen or bathroom backsplashes, we recommend using regular siliconized acrylic caulking. These areas aren't exposed to the high quanities of water that the walls and floor of a shower are, and don't require the heavy-duty water-resistance of a 100% silicone caulk.


Silicone caulking is also a lot more flexible and stretchy than acrylic caulk, so if you have a dry area with high flex and your acrylic caulking keeps separating or tearing, use silicone instead.
