Review: SpectraLOCK epoxy grout

Kate uses epoxy grout to grout the “fussy” mosaic tile on her bathroom floor

vintage-tile-with-dark-groutpink bathroomAfter all my hard work installing the mosaic floor tile in my master bathroom,  it was time to seal it all in with grout. Not one to just slap any old grout on my beautiful new floor tile, I did much research to choose not only the right color grout — but also to choose the right grout product. I was scared to work with epoxy grout for the first time. But I used it — SpectraLOCK epoxy grout(*affiliate link) in particular. It turned out to be much easier than I expected — and it looks great. Read on for the complete grout saga–>

mosaic-ceramic-tile-floor-pinkChoosing the grout for my mosaic tile bathroom floor

In the past, I’ve only ever installed white grout — on my bathroom and kitchen floors in my first house, as well as the kitchen backsplash in both my first and current house. All of the floor and wall tiles in every place that I’ve lived over the years have always had white grout. Here’s the thing about white grout though — it shows dirt so quickly — especially on floors. When first starting to plan my bathroom remodel, Pam bestowed her bits of bathroom wisdom on me — number one — don’t use white grout on the floor. It isn’t just Pam who has been warning me away from white floor grout. Several readers have also recommended to use a dark grout color — not only for ease of cleaning — but also to help the light colored tiles really pop. After contemplating all their advice, I agreed to break my previous white grout on the floor cycle — and go with a medium grey.

Next came the research into which type of grout to use. If you’ve looked at grout before, you probably know that there are sanded and unsanded grouts — and that decision really comes down to the size of your grout joint and the type of tile being used, meaning your tile selection and desired spacing basically dictates that choice for you. My dilemma came down to another lesser known, grout decision — to use traditional cement grout or epoxy grout.

spectra-lock-epoxy-groutAfter researching both traditional cement grout (which I have installed before) and epoxy grout — specifically, SpectraLOCK epoxy grout (*affiliate link), which I chose because it claims to be the easiest epoxy grout to install and my father has used it before with great results.

During my research phase, I compiled a list of pros and cons for each grout type:

Pros of traditional cement grout:

  • Familiar with installation methods (I’ve installed this several times before)
  • Traditional product used to grout tiles pretty much since the invention of tiles and grout
  • Cleans with plain water, can be removed even if it dries on tile surface
  • Cost effective
  • Easy to install with long working/cleaning time

Cons of traditional cement grout:

Pros of SpectraLock epoxy grout:

  • Color is consistent and not affected by efflorescence
  • Stain proof/easy to clean
  • Never needs to be sealed

Cons of SpectraLock epoxy grout:

  • Expensive
  • During installation process, washing must be done quickly and completely with vinegar water solution before grout has time to try on tiles. Haze and grout left on tiles is very difficult/impossible to remove
  • Short working time — grout stiffens and becomes harder to work as time goes on

natural-grey-spectra-lock-groutAfter listing all the pros and cons of each type of grout, I was still left conflicted. Mostly, I was losing sleep over two important pros and cons of each type of grout installation:

  1. Regarding the traditional cement grout: I was terrified that using dark grey cement grout would result in efflorescence and uneven color (remember, in the past, white cement grout has been my go-to choice — I’ve never installed a colored grout before), resulting in a ruined floor job.versus:
  2. Regarding epoxy grout: I was terrified that the glazed texture on my mosaic floor tiles would “hold onto” bits of the epoxy grout and make it difficult or impossible to fully clean the tiles, resulting in a ruined floor job.

Feeling “darned if I do, darned if I don’t”, I considered the main benefits of taking a chance with the SpectraLock — my color would be even and I would never need to seal it. After all of the time I’ve spent working on this bathroom so far, the idea of having to seal the grout every year or so didn’t excite me. Finally, after many restless nights, I summoned the courage to try the SpectraLock epoxy grout in my bathroom.

My color choice: SpectraLOCK Natural Gray

Without being able to see any actual samples of the grout colors (besides online and what was printed on the package label) I was nervous about picking exactly the right color grey. After researching comments and reviews online from people who had used SpectraLOCK grout colors in their tile projects — I discovered that the grout often is slightly lighter than the color swatch on the package, and that the color darkens as it cures — meaning the initial color when mixed won’t be the final color. Taking these bits of knowledge into consideration, I decided on Natural Grey — which seemed to be a nice warm, mid to dark grey on SpectraLock’s color chart.

Taking Pam’s advice, I had prepared a sample tile board with leftover floor tiles so I could test install the grout for both color and ease of removal from the tile’s tiny bumps. I took a deep breath, mixed up a batch of the grout, and tried it on the sample board. To my delight — success! Knowing the color would dry a few shades darker, and noting that the grout didn’t stick in the tile ridges (probably because of the high gloss glaze) I began grouting the bathroom floor.

When installing epoxy grout on mosaic tiles, use an epoxy grout float, held at a 90 degree angle and draw diagonally across grout lines to squeegee excess grout off tiles without removing grout from the space between tiles.

Tips to using SpectraLock Epoxy grout:

  • Be sure to follow all instructions to a T — including using an epoxy grout float(*affiliate linke)(shown above) to install the grout instead of a regular grout float. The epoxy grout float is heavier and more dense, which helps it act as a squeegee and get much of the excess grout off the tile with the float, leaving less to wash off later.
  • The grout does not stick to the epoxy float — not a problem when working on the floor, but I could see installing it on walls or ceilings would be more difficult.
  • The SpectraLOCK epoxy grout does get harder to work with as time progresses, for best results, use two hands to pack the joints with grout and work quickly. I found that I had about 30 minutes from mixing the grout to the first wash (it was 77 degrees in my bathroom — grout hardens faster in warm temperatures). Since the buckets are small, I did not find myself wasting grout, but you need to mix a lot of batches to do the whole bathroom floor. Plus, grouting the floor felt like a total body workout.
  • Coverage depends on the size of your tile and grout joint. For my project, each mixture of grout (Parts A&B + Part C colorant) covered about 8 sq. ft. Each mixture cost me about $24 and I used 8 units, for a total cost of $192 — not cheap.

epoxy-grout-with-tileIn the end, I am very satisfied with the finished look of the SpectraLock epoxy grout. Having installed traditional grout before, my opinion is that the SpectraLOCK epoxy grout is no more difficult to install (at least on a floor) than traditional cement grout when directions are followed and proper and thorough cleaning is done. However, I’m sure the type and size of tile that is being grouted (as well as the finish) plays a huge part in my assessment. I am contemplating also using SpectraLOCK to grout my pink tile walls, but am worried about working with smaller grout lines on a vertical surface during the install.

retro-pink-tile-floorPutting aside fears of grouting the wall tiles, I can say that I am in love with my retro pink tiled floor. The dark grout looks fabulous, and really does allow the light colored tiles to stand out and shine.

Readers — have you used dark grout — or epoxy grout — on a bathroom floor before?

    Kate-

    You & Pam are my hero’s!
    I love that you both take on & complete projects that many women wouldn’t even consider trying.
    My 15 y/o daughter is always asking me what projects are on the website & I love showing her, I want her to be prepared when it comes time for our remodel!
    Your floors turned out beautifully & it’s great to see how you started from new, but it looks vintage. Your new bathroom is going to last you years & I love the idea of grout that doesn’t need resealing, fabulous!

      Aww thanks 🙂

      My dad has always been handy — doing his own remodeling and repair himself. When I was in my teens, he started letting me help him on some projects. As I got older, I learned more and more from him. He never told me I couldn’t do something because I was a girl — he told me I could do anything I put my mind to, I just have to learn as much as I can about the task at hand and then just do it. If I make a mistake, I learn from it for next time, or start over and fix it. He taught me the value of hard work and figuring out/doing things like this for yourself. It is an amazing feeling of accomplishment when you are done — and it is never easy, but I’m always glad that I do it. As you can imagine, Dad (and mom) are very proud of all I’ve accomplished on this bathroom remodel so far. 🙂

    You are a bathroom remodeling genius! I can hardly wait to get started on my own bathroom… I just need to find the perfect house first. 😉

    The floor looks great and has that vintage appearance. My issue is the color of the grout. It may (again) just be the digital reproduction and monitor, but, from eye level, the grout appears to be brown and imparts a brown hue to the tile.

    The tile work looks great. I have 1950’s peachy pink bathroom fixtures and I’m having trouble finding tile colors to match. These look very close to my color. Where did you find them?

    Hello,
    I have this type of mosaic style in my bathroom and the grout is as old as the house (’56), it needs to be redone.. can you give me tips or recommendations on how to regrout this tile?
    Thanks
    P.S. love your bathroom!

    • Kate says

      Hi Fabiola,

      I’ve never regrouted any tile, so I can’t offer much in the way of advice. I did read somewhere that SpectraLOCK can be used to regrout tile, so perhaps consult a professional or contact the company and do more research? Good luck!

    I’m getting ready to install a similar tile in white. I think yours is stunning! I absolutely love the way the grout makes the tile details pop.
    I want to use a similar color grout (dirt is a fact of life, why fight nature?!?) and was thrilled to see how good yours looks installed.
    I’m just wondering, are you still happy with the SpectraLock, now that you’ve had it for a while?
    And do you have any idea of the SpectraLock coverage with the mosaic? I’ll have to order it, and I have absolutely no idea how much I’ll need, and I can’t find a clue online.
    Congrats on your fabulous bathroom, you’re amazing!!

      Thanks Robin!

      It’s been nearly a year and a half since I finished the bathroom and I’m still loving the SpectraLOCK grout. It looks brand new (as it should!). I’ve also used it to regrout the walls in the shower in my other bathroom and that went well also. I don’t remember exactly how much I used for the mosaic floor, but I do remember it was more than I calculated needing based on their coverage recommendations for the amount of square footage on their website. I had to make another trip to the store. If you have to order it, I would order slightly more than you think you are going to need. It looks like they’ve added a “grout coverage calculator” to their website, which may be helpful: http://www.spectralock.com/installation/coverage.aspx Hope that helps! Good luck!
