Glow in the Dark Grout?

I went to Lowes yesterday, and I saw that they started selling SpectraLock grout. They also have an additive that will make the grout glow in the dark. Has anyone used this? My wife said no way, but wouldn't glowing grout be really useful in a bathroom? No more stubbed toes on the vanity?

Just another gimmick-- it doesn't glow THAT much. Forget the night lite theory!!

That's what I figured - and it was pretty pricey too. The picture in the brochure made the floor look a little radioactive. Maybe I'll do something crazy and buy a night light instead!

It IS radioactive. Remember the radium dial watches?

Well, no, maybe you don't remember them. Maybe it's just me.

Radioactivity

Would this radioactivity warm up my feet on cold winter mornings? I'd be the first one on my block with a nuclear powered floor!

Too late

The mortar, grout and cement backer probably already contain trace amounts of radium.

It is fairly common in sand, minerals, and cement products.

My guess is that the SpectraLok stuff uses genes spliced from phosphorescent plankton. Perfectly harmless - but watch out for whales feeding

Glow in the dark grout.

Actually, we are in the process of adding glow in the dark grout to our inventory. We are futureglo and we have some Glow in the dark ceramic house numbers, wall and floor tiles. Grout was the next logical extension. Visit us and see what you think

First, let me disclose that I am a Senior Technician for Glow Inc., a company that manufactures glow paint.

I realize this thread is a bit old, but you can make a home-made glow in the dark grout that is brighter than is readily available as a premix. It is also considerably cheaper to mix it yourself.

You simply need to buy a special raw phosphorescent pigment called "Coated Glow in the Dark Powder".

The "coated" part is a sealer added to regular glow in the dark pigments that protects them from water and chemicals.

You can then mix this with regular grout mix up to a 20% ratio.

Since you are buying your own pigment, you can choose grade, ratio and color.

Hope this helps, I would love to see pictures of completed projects.

I picked up some SpectraLock Dazzle Glow very cheap on Ebay (well compared to the retail price anyway); seemed fun for a 3/4" glass mosaic project. A novelty yes.

Anyway, after checking the Dazzle Glow MSDS and searching around I ran across GlowInc offering the same basic stuff and ordered some small samples.

From the MSDS and some basic test pieces; their product appears to be the same as the Dazzle Glow but clearly brighter and cheaper (but not as cheap as the Ebay price I got); plus multiple colors.

I inquired with GlowInc about the product brightness differences and got an excellent technical answer on glow particle size and quality levels (since the basic MSDS info is identical) from Danny.

I'm not sure about the "coated" part he mentions; GlowInc has a special water-safe version of their powders but in limited colors. They don't list a separate MSDS for it; so I can't readily guess whether Spectralock Dazzle Glow is like that or like their standard powder (available in many more colors).

I did test GlowIncs standard glow powder in SpectraLock and it seemed to work fine (of course I can't comment on long-term durability). Dazzle Glow corresponds to the GlowInc "Pure Blue" color; the colors look identical but the GlowInc product is slightly brighter (side-by-side it's obvious). Their Ultra Blue is WAY brighter than both; but fairly greenish in color.

So aside from the question on the "coating" issue; their product seems to be a direct replacement for SpectraLock Dazzle glow and therefore is something that has been tested by the manufacturer (assuming you're not worried about the Laticrete warranty, etc of course).

BTW the Dazzle Glow container lists the contents at 4.5 oz (for use in one mini); but in fact the contents weighs approximately 6.5 oz on average - important for comparing prices and orderi. Laticrete gives instructions on withholding essentially the same weight in sand to make the mixture turn out right.

My wife isn't overly impressed with the result (go figure); although it doesn't make any difference with any minimal lighting so she doesn't mind it. But my 5 year-old thinks it the coolest thing in the world. And we will be repainting the glow-in-the dark stars on his sealing with GlowInc paint as the results are incomparable to the over-the-counter product my wife previously used.

And no; I'm not affiliated with GlowInc in any way. I just spent quite a bit of time digging around to figure out what Dazzle Glow really was and how it could be obtained. Maybe I tipped Danny off to the existence of the Laticrete product and by search-engine reference this forum.
