POLYBLEND vs. PRISM --- Which Grout Should You Buy??? SHOCKING TEST RESULTS!!! 

Thank you for this test Isaac. Good to know. Glad I used the prism. First time I had used prism and really liked the way it applied.

Thank you for all that you do, I had very low expectations from the old grout testing video, this was surprising.

We love inspectors like Cy..

Isaac, thanks again for another great product testing video. I trust your tests on products and no one else does this. I also appreciate your appeal to people to enter the tile trade, maybe especially the younger generation that might not have experience with this type of work. Some people naturally excel at building and making and get great satisfaction from that. I am one, as you are, and the money is good.

I really like mapei ultracolor F/A

This video really helped. Great Example.

Doctor of Tiles. Great test!

Thank you for the video 👍

Awesome test.

Thank you, appreciated

Prism is really great grout! Awesome video you did here Isaac!

Very interesting video, thanks! These days I usually go with mapei, but if a client specs prism I'm comfortable using it. I feel like the aggregate is a little bit more coarse, and the white colors have a lot of larger dark flecks of aggregate that stand out.

This video dropped just in time. I recalled watching your first grout test two years ago. That was my first shower project. I'm now on my fourth thanks to you.

Very good video. Prism is the grout to use.

Wow Tilecoach in the orange store. Now I've seen everything.

I used the polyblend for my front yard tiles after 5 yrs. It is still holding.

I'm really liking the Mapei FlexQ apoxy...Might very well be my go to grout🤟

Whenever we have used Polyblend or the Polyblend Plus in hotels, we are sometimes asked if we sealed it with a chemical spray because of the sand. You can always tell when the sealant wasn't used because within that first month tiny chunks will sometimes come out and it'll have to be re-done. It really depends on weather (temperature near the front entrance) and moisture (mopping by hotel staff or soaking wet floor mats) specially in heavy foot trafficked areas like the lobby and other entrances.

Isaac I want to start off by say I am a Mapei fan! Hold onto those samples and retest after 7/24/24 or longer. The Prism is like hydraulic cement and probably has an earlier cure time! The Prism is designed to set up in the tile joints of tile that do not absorb water like typical ceramic body tile. It's my understanding that the Prism will yield more color consistency and not require a sealer, and the standard grout is just the opposite. After you have wiped the grout with the sponge, the yellow micro fiber rag when soaked in water and rung of all it's water will clean far better than the sponge and leave less water residue on the joints and grout surface. Some times eliminating the need for multiple rinses.

Been a tile setter 26 years. And I like prism. Never had an issue. Easy clean up. Used everything under the sun. Still like prism

❤ science, I love it

Imagine having Cy on site keeping contractors from stealing power and water from resident's finished homes. I build custom homes and love inspectors like him. If I'm charging someone a million plus for a home in Atlanta I want that thing to be as close to perfect as possible. If you work to your utmost ability a guy like that shouldn't scare you. Don't be a thief and don't do shit work and you'll be just fine. Pretty easy.

Very interesting. My belief is that mixing ratios are critical, and the primary source of poor grout performance. I watched your earlier grout testing video with the group, and I thought the grout mix was visibly too wet and soft. Not so in this case. Totally agree about the ratios stated on bags, I invariably add more than standard recommended amounts to make the thinset or grout workable with my increasingly arthritic old hands. Plus you need softness for complete contact, and for full proper grout filling. It’s a fine line though, you want the minimum amount of water necessary to make the install smooth. I’ve had polyblend which slow cured in cool conditions to a hardness I could scarcely believe - I could hardly scuff it with my knife, and it took full on hammer and chisel to make a mark. Thanks, great work continuing on this channel.

Prism is my go to in a pinch. Polyblend has let me down a few times. When we get a custom job we hit the tile shops in my area. By far though epoxy grout is my preference

Just started the video. Couple minutes in. I do wish you also bought the pre mixed grout. They advertise that’s the best grout use.

Imagine having this guy around a job site 🤣🤣🤣🤣

I started off in 2005, using mortar by Custom Building Products. I've always Hated any and all of their grouts. Which was a good thing. Cus I found out about Laticrete. Using their stuff ever since.

Great grout video. I recently grouted my first tile job and used the Custom Poly Blend Plus un-sanded grout with 2 x 8 subway tile. My next job will have natural stone 2 x 2 mosaic floor. The tile manufacturer recommends using grout applicator. Can you please do a video for a floor like this? Thanks, your tile student

Have you tried Mapei Kerapoxy grout for shower floors? I love using it

Love your videos, on an off topic have your ever used Redi Poxy - Epoxy Adhesive ? I bought a Redi base & thought I would go with it. any hints I should look for ? Or any suggestions would be great.

Natural gray grout has always been a problem, in shady. Good demo.

Great videos... Do i need a pvc pan liner over a dry pack pre slope or can I just use a waterproof membrane then tlle over it????Thank you for your time

I would like to see another test with polyblend plus with Add MIx???

Prism is what I use. Over time it’s just lasted better. But the 1 thing I did years ago. Rino lined a shower stall ( yes spray in bed liner ) actually 2. 1 with tile. 1 without. And DAM. I’d say it’s better than anything out there. Hot mop. Anything. A few hours later you can set tile. Crazy

Curious if you have any thoughts on Fusion Pro. I'm a diyer and have been watching your videos for a couple of years. I'm finally starting a bathroom remodel in my house. I've demoed a bath shower surround and I'm installing 24x24 porcelain tile from Deltile. I've decided to use Goboard and Multi Max lite. I've used Fusion pro on smaller projects and it seems good. I'm hoping to get some insight from you or others. Love your videos! Very informative. Thanks

I use prism nice to see this test though-good job ty

I am still waiting to see the headlamps

Mapei Flexcolour CQ I have installations that are 10+ years old, grout looks like the day installed. Behind cooktops in the back splash , is one tough place for grout, it is the only one I use there. Don't use it everywhere, but sometimes wonder why not. Cleanup maybe ,,

I've seen that epoxy grout in the tubes, I assume it's very pricey, but wouldn't it be the strongest and most durable? Might be a good option for the tiles on the floor vs the walls, Since they just hold / see more water.

Prism says it doesn't need sealing. Is it just for the first year or no need to seal at all?

Does grout sealer improve durability?

My grout is old and not great. Can I just remove it and replace it? Thanks Declan

Glad to know the custom made Prism harder.

You should test PCI Nanofug grout from Germany

Fuckin with Cy are ya? We know you shoddy builders don't want an inspector around who actually does his job! 😂

I call that place the BORG. Big Orange Retail Giant.

What grout do you use on your jobs

I'm looking for a video comparing epoxy grout and sealer products!?!?? 🙏🏼🤔🤞🤷 ?????

Is that the same Marshalltown V-notch trowel home depot sells for $18?

What happened to the 7$ bag of C-Cure! Lol... It also matters how the grout is mixed! I will say the Mapei FA is the way to go over all others. Mixed correctly & dosn't need any "SLAKE" not "SLACK" time b4 application. It does have a faster work time 1hr but when completed & does have the time to cure, it's bulletproof! Metal Marshalltown/Barwalt margin trowels will definitely scratch natural stone if used vs. grout float.

Did I miss where you sealed the polyblend??

How does Spectralock 1 compare to Prism?

Only ultracolor. Always. Be sure to use distilled water for always perfect results

I hate custom products. The efflorecense is crazy. I never had a problem with laticrete or mapei.

Can you test TSG by custom?

I almost always use Prism now. You gotta be quick, it goes off fast

Since Prism doesnt soak up water ( after cured), it is probably more stain resistant.

Polyblend requires more water then specified because of the sand

What thin set for laying tile is best at the box office store, or do they have it?

Shouldn't you seal the grout before doing that test?

This grout test is like watching Project Farm

What are your feelings on epoxy grout?

Laticrete Sprectralock Pro

I need you to build a bullet proof shower in san jose please!! I've tried messaging through your site

stronger than spectralock?!

I bought Prism for my kitchen floor and it's awful. It just rubs right out of the grout lines like it never fully hardened.

Wish the test was with lighter color. Light tan seems to never hold its color.

It is easy to test a 4 Sq inch spot but what about test a whole entire bag at the specs they give doing 900 maybe 1500 Sq feet. Do the test on a big job then do a video 🙏

What’s your beef with cyfy lol

I'll tell you where I'm not buying it. Home Depot.

Temp is the final determination.

Arent you the guy getting called out by Cy for stealing neighbors power for a job?

I unfollowed and unsubscribed awhile ago do to you not doing proper testing on your videos. Imagine talking shit about an inspector! You should be lucky you are still the trades. Sub out more work to weirdos you don't pay enough. It's so obvious.
