BEAUTIFUL bathroom, thank you for sharing!

[@AndrewThronImprovements]

I appreciate it! Thanks for watching!

[@OGCJ10]

I used this exact grout for my bathroom shower floor (mainly for its water resistant properties) I wish I would have used it on the walls as well. Highly recommend and it doesn’t require maintenance like regular grout does

[@tinawatson2050]

Great job...I Love, Love, Love this!!!!

[@AndrewThronImprovements]

Appreciate it, Tina! Thanks for watching!

[@hayleybeckman2411]

Thanks for sharing. I was told do you epoxy in showers to help with mold or moisture build up. Thanks for the confidence to try this! Great work!

[@AndrewThronImprovements]

I agree that it's definitely the way to go in showers! Thanks for watching and good luck with your project!

[@Munchiie]

Man! Great channel.. Love the content!

[@AndrewThronImprovements]

I appreciate it! Thanks so much for checking it out!

[@EPHONIC]

Thanks for the video. What tools are best used to get the grout into small grout lines and corners between the floor tiles and the wall tiles? I’m redoing my shower.

[@jimmazzochi9122]

Gooood job !!!!

[@AndrewThronImprovements]

Appreciate it!

[@kinkinmyslinky967]

Did you have any issues with the epoxy grout setting up/hardening in the pail while you were working?

[@davidgapp1457]

Actually you can use an epoxy solvent up to around 3 days after grouting to remove any haze or accidental streaks. I use a product called 'Attack' which is very strong and dissolves nitrile gloves in seconds. However, you can use quite a few other agents including Goo Gone. Attack is really only needed in extreme cases. As for large format files (aka 24 inch) I actually tape them using the widest 3M Blue Fine Line tape (kinda like plastic). If you're careful, the cleanup is zero. Obviously with tiny tiles... that approach isn't going to work. I have used epoxy in quite a variety of situations - even an outdoor barbeque area and several showers. The end result, provided you're on a very solid substrate, is fantastic. Not a substitute for expansion lines, of course, where you'll still want a traditional grout caulk.

[@practicalchurchtech]

Love that shower door. I have a master bathroom with a near identical layout and have been looking for a good option to have a wall-to-wall door that doesn't hit the toilet. Was that custom made?

[@AndrewThronImprovements]

Hi! I appreciate it! And no I actually got the bifold door online. I forget exactly where, but I made a video that has a link to the product in the description: kzbin.info/www/bejne/ZpKzqX2fjtVmY7c Thanks for watching!

[@beckyleung7233]

very good

[@AndrewThronImprovements]

Appreciate it, Becky! Thanks for watching!

[@tedspens]

Nice job! Spreading that epoxy looks like quite the workout. Think how much people pay to go to a gym to do basically the same thing.

[@hidvisioncanada5602]

Hi Andrew, I have a small gap between the knock down ceiling and the tiles. How do you go about filling the gap without getting grout on the ceiling? Also, do you grout the vertical shower corners or caulk them? Thanks.

[@alexanderbattaglia2916]

Another informative video!!!

[@AndrewThronImprovements]

Appreciate the continued support, Alexander! 👍

[@anseldominguez4585]

Wow your bathroom turned out amazing!! Just out of curiosity what are the dimensions of your bathroom? I'm planning to do a bathroom and the layout you have would be perfect for my basement.

[@AndrewThronImprovements]

I appreciate it! It was about 4.5’ wide by 9’ long when I started. I stole about 18” from the closet to get my extra length for the shower. Thanks for watching and good luck with your project!

[@sherislick]

Were you standing on the freshly grouted floor while you did the walls? How long did you have to wait to do that?

[@jackhargreaves1911]

Amazing job. You are a master. But it confirmed my suspicion that using epoxy would be too hard for me. Pity…

[@sunk1m54]

Hi there! What color of the Mapei Kerapoxy cq did you use? I read a lot of reviews about the Mapei line of grouts drying much lighter than the original color from initial mixing. Would you say that was the case for this epoxy grout? Thanks!

[@parkedpridemedia]

not for epoxy, its colour fast and will match the silicone with the same colour code once complete. just make sure whoever is applying knows what they are doing. you will experience the colour difference with the cement grouts though, especially mapeis ultracolour. and there will be a significant difference in the grout and the silicone colour even though its the same colour code. just be aware of that.

[@bridgetbean79]

Can I do this directly overtop standard/gritty/sandy grout I have without removing it or scouring it? It’s recessed from the stone tiles, I really just want to slap epoxy grout right over it 😅

[@bmwdragking1]

What grout is good for a polished mosaic tile floor very lost?

[@jasminecommercemusic]

Thank you for such an informative video. I guess my question would be why you didn’t use white epoxy grout to match the tiles?

[@AndrewThronImprovements]

Thanks! I honestly just liked the contrast since I went with the herringbone tile pattern but white grout would look good too.

[@jasminecommercemusic]

@@AndrewThronImprovements I've since been studying up on white epoxy grout and apparently it has a tendency to yellow quite a bit, so looks like you made a great choice!

[@KellyJelly9976]

The bathroom turned out amazing! Would you use the epoxy grout if you had the choice again? Did its future pros outweigh the price and labor cons?

[@AndrewThronImprovements]

I probably would! I have regular grout in my other bathroom and, although it was way easier to apply, it looks pretty rough now!

[@nathand2630]

Hello! I Just had a builder finish my bathroom but this same epoxy grout they used has a rough surface and not smooth. Is this supposed to have a smooth finish?

[@AndrewThronImprovements]

Hi Nathan - mine has a little bit of texture as well. I think it is just the product. Thanks for watching! Hope you like your new bathroom!

[@Johnnylove15]

Did you grout the bottom expansion joint before caulking? Im at that point in my project.

[@AndrewThronImprovements]

I did not - I just caulked

[@dmples2012]

Anyway to remove excess grout if u happen to mess up? (If the grout dries on you)

[@AndrewThronImprovements]

Hi Marsha, if it’s the haze you are trying to get rid of, I would try some type of “grout haze remover” solution with a pretty abrasive sponge. If it’s larger areas of dried grout, you might only have the option of trying to scrape it off with a 5 in 1 tool or something similar. Just make sure the scraper isn’t scratching up the tile. I’m not an expert on this, unfortunately, but good luck!

[@johnathanw.336]

How quickly did you need to clean up the excess epoxy grout out so as to avoid as much haze as possible?

[@AndrewThronImprovements]

I was paranoid about how bad the haze was going to be based on my research. But it honestly wasn't too bad. Within 10 minutes or so after we finished grouting.

[@gloriacarina1]

I know you have to work quickly once mixed, but how quickly?? is an hour for the whole shower too long?? Can someone give me a time frame ?? I've installed tile and grout before, I think I can swing it. As along as I dont have to do this within 15 min.

[@AndrewThronImprovements]

Hi Gloria! I was freaking out about time as well. But I would say that grout remained workable for about 2 hours. Some people swear it sets up immediately, so it likely depends on the manufacturer, temperature, etc. I tested it out on the shower floor first (small space) to get a feel for the pot life. Good luck!

[@gloriacarina1]

@@AndrewThronImprovements thank you so much!!!

[@Pure3nrg]

When you mixed the grout how long do you have per bucket before it gets to hard to work?

[@AndrewThronImprovements]

Hi! If I recall correctly, I had around an hour. However, check out your specific epocy grout manufacturer's recommendation.

[@fabianaazurmendi8558]

Are proportions provided for different amount of grout needed? It seems like it is too much for my project

[@Pure3nrg]

@@fabianaazurmendi8558 you buy the size at your retailer, I had a lot left over, but it only comes in certain sizes.

[@johnbatista5533]

What is the cure time?

[@KarKeeLaiz-qd8tl]

What if my tiles surface is rough texture. Will the expensive epoxy stain the surface ? 😅

[@AndrewThronImprovements]

Ohhhh yea I feel like epoxy grout on textured tiles would be a nightmare.

[@tabtab6214]

What type of caulk did you use for your joints?

[@cynthiaaranguiz3057]

Same question

[@grilledchickenwrap]

Hi.. so for the 4 sides of the shower floor and wall you just filled it with silicone ? Is it good enough to seal out water from getting in ?

[@AndrewThronImprovements]

Hi! There are different schools of thought on this. Some say you should grout corners and others say you should NEVER do that. I personally think that sealing all changes of plane with a high quality silicone is the best way to go for waterproofing and to prevent cracking. Thanks for watching!

[@jayheh]

@@AndrewThronImprovements I couldn’t see properly while you were spreading the epoxy grout on the floor tiles, did you cover the perimeter as well and then on top of that add a silicone layer? Thanks!

[@danrichards496]

I can’t tell you how many times I’ve seen grout crack in corners. Houses settle, expand and contract and it will most likely crack.

[@sew2prosper]

If you don't mind, what are the dimensions of your bathroom?

[@AndrewThronImprovements]

Don’t mind at all! It was about 44" wide by 9’ long when I started. I stole about 18” from the closet to get my extra length for the shower. The shower ended up being just under 36" x 36". Thanks for watching!

[@CLight-vc9pe]

I would like to understand why you didn't use epoxy grout in the wall/floor joints. That is where I have the most mold.

[@AndrewThronImprovements]

Hi! Honestly, there are different trains of thought on grouting vs. caulking the floor joints. If you are using a cementitious/sanded grout, I would recommend that you use high quality caulk in the wall/floor joints. If you are using epoxy grout, you might be ok with going with grout in those joints. From my research, caulk is usually the safer bet for all changes of plane since it allows for expansion/contraction/movement better than grout. However, some contractor's just grout EVERYTHING and swear that they have never had an issue with cracking. Hope this helps!

[@owl4]

@@AndrewThronImprovements Im in a newly built home and they used grout on floor joint and there’s a crack already…I have to now replace that strip and caulk it.

[@ArtOfTheWeld]

seems like you added epoxy grout inside the joints, and then caulked the joints after . is this the way? or should I pull out the epoxy that seeps inside the joints first before caulk

[@Affordablebath_remodel]

at 90 degree angles that is where you most likely will get a crack from the movement of the walls. Standard tile work is to caulk these corners.

[@MikeMurphyinc]

Has it stained or discolored at all so far?

[@AndrewThronImprovements]

Hi Mike - After a year I am very happy with the Epoxy grout. No real signs of staining or discoloration at all. Thanks for watching!

[@MikeMurphyinc]

@@AndrewThronImprovements I'm thinking about digging out some of the grout from my floor tiles and replacing it with the epoxy grout as they look like crap and the house is only 3 years old :)

[@homehero3334]

How much more expensive is this type than regular grout?

[@AndrewThronImprovements]

I would say around 3x more expensive. The 1 gallon tub I used cost $115 and covers approx. 275 SF. Thanks for watching!

[@danrichards496]

If you don’t use this type of grout, you are supposed to use grout sealer taking a small brush and going over every grout line three times waiting for it to cure in between which I think is 24 hrs between coats and I don’t think the sealer is permanent either. You can’t get it on the tile and I’ve seen it make the grout look glossy and wet. I don’t think hardly any installer uses it either because when you dig up a shower floor it’s wet. Epoxy grout seems like the way to go.

[@phsx2890]

Do u seal it also

[@AndrewThronImprovements]

Nope - no need to seal epoxy grout!

[@garryswift4073]

comes in tubes these days

[@MrTreyaflash]

Once parts A and B are mixed, will it keep overnight or do you have to do it all at once?

What grout color is this

Mapesil T Silver

[@Prxyshj]

Isn’t grout meant to be porous?

[@alicesconstantinescu]

Just one thing, the grout colour could've been lighter, to make the bathroom look more open, bigger. Otherwise lovely work
