Question: Can this polish concrete?
Document: This is a crappy polisher. I got this polisher due to the good reviews but the bearing went out  after a 3 concrete counter tops. Also it is almost impossible to do any work in a side ways position. The water gets under the switch and trips you ARC or GFCI instantly.Such a waist of my time and money.
This worked great and was a lot of fun. I did a 3' x 5' concrete countertop. If I were to do this large of a surface again I would buy a 7.5&#34; instead of 4&#34; but this definitely did the job. Only did the one project so I can't comment on longevity. The adjustable water supply was nice but I imagine this is standard for all wet polishers.
I tackled making concrete coutnertops myself and I poured them in place thus the top was far from smooth when completed. This polisher made quick work of getting the countertops smooth. After a few hours they were as smooth as granite. If anyone else tackles a project such as this I would recommend building a mold outside then bringing the countertop in. It makes quite the mess in the kitchen when polishing.
Having seen a few negative reviews, I was skeptical. But this is a great t ool for do it yourselfers. I poured concrete with wine/ beer/ bottles as crushed aggregate. This made a great bar counter. Ground to a nice counter finish. I used sealer to get a high shine. This project looks like granite - for a lot less!Not sure how long the tool will last, but so far (14 sq ft) it works great!
I bought this the polish the edges of some granite that I used as a backslash in a bathroom remodel.. Easy to use and did a great job. Polished the edges like a factory finish.
Exactly what a DIY needs to polish your own granite for the first time. You just need a decent youtube site to tell you how to use each polishing pad. Learned by trial and error. Shaping contours with 50-200 grit. Don't skip any pads and give each the same amount of time and effort. Practice, practice, practice.
I bought this to refinish a terrazzo shower base that is 15 years old. It has a water feed attachment, a set of diamond grinders from 50 to 3000 and quality motors and safety features. I made my dough back with this guy from one project. It can also polish ripped marble and granite slab product. Great beast for the money.
This way the tiles didn't move when grinding the front edges. Be careful that the tiles are at the same height; a warped plywood surface won't work. In this way I could round and polish the tiles as if they were installed on the counter but work outside. I started with the 50 grit but found that I actually added scratches, so next time I will start with 100. Work through all the pads, finishing with 3000.
I bought this wet polisher with diamond pads to polish the edges of granite tiles that I am laying on a kitchen island. The cut edges are very dull and have some blade marks coming off the tile saw. I wasn't sure that I could do a good job with it, but I took the chance. Adjusting the water flow to a trickle was easy. A trickle is enough water to do the job and not get too wet.
I bought this tool to polish a swimming pool re-plaster job, & it has made my poor plaster skills look great. I've used the 50 & 100 grit pads only & have since purchased more 5&#34; 50 & 100 grit pads.The grinder has even tolerated a lot of water spray when running without spray guard. Not recommended, but the guard gets in the way when polishing a radius.
Answer: yes
