Does anyone know how to color grout in-between cermaic tile .. I have white grout now and it got dirty was wondering if have to scrape out old grout to redo it or just put down newer grout over the old grout. Thank You! — Judy
Thanks for your question, Judy. Yes, the common thought is you should scrape out the old grout before you put down the new stuff. It’s a pain, but not as hard as it sounds. Check out this how-to over at This Old House. They say the job can be done with a simple, pointy-tip bottle opener. Over at e-How, their advice is similar. It is best to match the new grout color with the old, but that doesn’t mean you still shouldn’t get rid of the old yucky stuff first.
