I thought it was over and done. But then a Twitter follower casually mentioned that I should seal the grout (thanks, @magruffman). I had no idea what that was about, since none of my reference books mentioned that at all. It turns out that grout is actually rather porous, and to make it water-proof it requires a sealant of some sort painted over it. So I waited a week to make sure that the grout was fully cured. Well that and because I didn’t feel like doing it until the weekend. So a quick trip to the hardware store (any excuse to go there is a good one) and I had picked up the appropriate goop and applicator (and some other stuff, but SWMBO doesn’t need to know about that).
Here’s all the fixings ready to go. I must warn you that the magic goop ain’t cheap … that little bottle was $30!!! Must be made from unicorn urine or something. Oh, and there are no instructions on the bottle itself … you gotta hit their web site.
Applying it pretty straight-forward. Fill the applicator bottle with the magic goop, invert the bottle, and paint it on. See how it shines! Two coats seemed to do the trick.
Eddie Cat loves watching me work, and insists on checking the quality of the work.
And that, hopefully, is that. I let it set for several hours, then put a few drops of water on it to check the sealing. The water beaded up and just sat there. So job done, I think.
