I've been using it but it's very expensive. The grout powder appears to be normal grout... could I just combine it with some sort of epoxy mix?


echo Michael. I've used Laticrete's SpectraLock.. There's a lot of engineering there to allow water based haze removal (OK, you do need to add white vinegar, very cheap and non-toxic). Spectralock installation

Off-the-shelf epoxy is going to require a solvent based haze removal (usually lacquer thinner, acetone, or alcohol).. much more hazardous (indoors you'll need an organic respirator) and adds to the cost. Checkout West Systems how to use instructions and videos.

Its doable, but...how many experimental batches are needed to verify proper resin/hardner.filler(grout) ingredient mixes so you get a mix that looks and performs like you want.. There goes your savings..

In the business of grouting tile? might be worth it. Doing a one off for a kitchen/bath.. buy a product backed by a warranty, videos, other users (like John Bridges' forum).

  • I know this an old post, but it is the only one that comes up on google. I've worked with a wide variety of epoxies and polyester resins. I've always used vinegar for clean up. Acetone is a good thinning agent but vinegar has never failed to clean up. Sometimes I use it straight without diluting it for maximum strength. Epoxy is not hard to mix and get correct. You can add hollow glass microspheres to thicken or for a white color.

I have done it with clear epoxy and micro spheres to create an un-sanded, white colored grout. I used it on a very small, thin glass mosaic tile. Vinegar and water worked but acetone worked better. If you are to use the spectralock part C I would add some white to the epoxy. My objective was to get away from a sanded product.

My answer to your question is "Probably Not".

That said you are of course free to experiment. Tryout you ideas.
