QUESTION

Matching a Grout Color - I need to match some grout on the front of my home facade which is historically preserved in Washington, D.C. Do you know a company which mixes and matches grout in this area or do you do it by mail? We only need a small amount. Thank you.

ANSWER

ANSWER - Manufacturer's of grout will custom blend grout colors for very large projects.  Knowledgeable tile installers can sometimes mix and match colors to try and patch an existing grout.

Even if you have the exact same grout as was originally used, it could still vary in color when installed.  Color of the grout will vary depending on how much water is used during mixing the grout and then during cleaning the grouted area.  The color will vary depending on the rate at which it dries from various conditions such as temperature, relative humidity, wind, and how absorbing the surface is to which it is being attached.

You can try to match the grout color and if it doesn't come out well you can get a grout colorant and paint the grouted area to try to better match it.  Good Luck.
