Step 7: Installation and Final Finish

I can't mention enough that concrete is heavy and you'll need people to help you with the final installation. I was able to move all of my countertops with 3 people, but that's because I did my biggest piece in 2 sections. Make sure you have a battle plan of how you'll move it and set it down.

The weight of the countertops will keep it in place if you just apply a generous amount of caulk on your plywood top. If you'd like added support or live in an area where earthquakes are prevalent, you may decide to drill underneath into the concrete and use tapcons to secure it further.

I also wanted to hide the 3/4" plywood top that supported the countertop, so I bought 3/4" by 4' strips of galvanized steel at Lowe's. I just cut them down to size and glued them onto the plywood edges using Liquid Nails. It adds another decorative touch and looks great!

If you remember, I had that aluminum strip that I wanted to be an accent where the 2 island pieces came together. To do this I cut the aluminum down to the proper length allowing it to stick up (and out) just slightly from being flush. I applied caulk to both sides of the aluminum and pressed the countertop together, sandwiching the aluminum and holding it in place. I then used 2 part concrete epoxy, which I spread over the aluminum and onto the concrete. After it dried, I ground it down with the wet polisher until it was perfectly flush with the 50 grit, then worked back up to 1500 grit to match the finish.

The Cheng Pro-Formula kit came with a penetrating sealer that I applied according to the directions which were simple. I chose to add extra shine and protection by polishing them with carnuba wax. The wax is heat resistant, so you can still put hot pans on the countertop without it burning, and gives added stain protection from acidic foods like wine and citrus. The wax needs to be re-applied about once a month in order to keep up the shine and protection.

So now I've got beautiful new countertops that I made myself! It was a lot of work and a fair amount of expense, but it was so much cheaper than granite and I was able to add details that you can't find in any other solid surface countertops. I'm going to enjoy my fruits of labor for now, but eventually I'd like to do an outdoor kitchen which will need countertops as well. I'll document that process as well when I get around to doing it.

I hope this helps you with your project and I'll be more than happy to answer any questions you have, so feel free to ask. Major thanks go to Mr. P and my brother who helped me with this project, I couldn't have done it without them.

Thanks for the help. I also bought the book. Together, the project wasn't that tough at all...
<p>How did you get that look? Did you just polish and seal it?</p>
cmc70 the countertops look great. Did you use anything extra to support the eating overhang on the island?
sj.. sorry I havent been back to here in a while. Yes, I used some Stainless Steel arcs anchored to the studs in the Island and the underside of the countertop. It is not finished here in these pictures. <br> <br>C <br>
I'm getting ready to pour some countertops for my new apartment and this instructable is a incredibly helpful. I already have the Cheng books, thanks to the comments here. <br> I read every comment (so far) and took notes. I figure that these orgnized notes from your collective wisdom could be helpful to others, so I put them up on my blog. This is no replacement for reading everything yourself! I am sure to have missed things and new comments come in all the time. <a href="http://sputterlyutter.blogspot.com/2011/09/collective-instructables-wisdom.html">Here's a link to my notes</a>.
Thanks, that is a helpful resource for everyone who comes here. Good luck with your project and really glad everyone here was able to help!

Great job on your tops! Now keep creating! Here are some photos of my most resent backsplash project in Park City Utah
Romac, your kitchen is beautiful! I wish I had the skill and patience to do all of that. The curve is very nice, too. (And that Buddha you carved is phenomenal: most impressive).
EXCELLENT JOB! Your kitchen looks fantastic and it's great to hear that my little project inspired someone else to use concrete for countertops. I really like that you poured it in place as well - I was too nervous knowing that water would be flying all over the place. That $60 worth of concrete and some elbow grease increased the value of your kitchen by several thousand dollars. Thanks for all the pics!
<p>Kitchen really amazing. Interesting if it can integrate well into various kitchens, saw a similar cuisine in Kitchenpt.com, interesting Outeda, really impressive about the honor.</p>
<p>wow, just wow!</p>
<p>challenge accepted!</p>
<p>i cant get quickrete 5000 or cheng pro formula what can i use in a basic concrete mix of 1 part water 2 part cement 3 part sand</p><p>are super plasticizers absolutely necessary or glass fibres? </p>
<p> I did an out door bar table top with concrete &quot;INPLACE pouring &quot; due to its size ( 2ft x 10ft) , top is uneven, by the time I finished pouring it was late and concrete was not enough to trowel to level so did a quick and dirty job of finishing it off ,( used a mix of GFRC and quickrete 5000 Mix about less than 2 inch thick,</p><p>after a week i tried leveling the top with another layer of sand cement ready mix ( no gravel ) and wasted 4 hrs topping and leveling the table but next day I checked it was popping off :( , just did not stick to the tabletop so frustrated I just scraped off the top . I think My selection of the cement ready mix was wrong . </p><p>Any one can give some pointers on which Portland cement with plasticizer , additive etc would work wonders to level this would be just great </p><p>This is my first countertop using concrete, don't want to give up. not so easy... </p><p>And yes of all the places I though this was a great forum to get some ideas on projects for a low budget DIY person with plenty of enthusiasm </p>
<p>I am planning to fix mine too.. great ideas, I benefited to it yey :D</p>
<p>I have poured 64 sq feet on counter top. I have some ruff spots in the counter top and I am at a loss. I sealed it but the ruff spots look really blouchey. I really like the gray look . If i polish the counter top will that get rid of the ruff spots and smooth it out? I sanded the edges with 220 but its still rough also. Please help me!!</p>
<p>I was pleasantly surprised. I visited this very Kitchen in Chattanooga, TN. The house got foreclosed on soon after this project was completed.</p>
<p>This is a great resource. I'm seriously considering making my own concrete countertop for our kitchen project. We have new custom cabinets of all 3/4 inch plywood construction, so I'm not concerned about weight and strength. My primary concern is that I want to do it in 1 piece, but our run of cabinets is 14 feet long. The counter would be 1.5-1.75 inches thick, standard 2-foot width. It would have 2 major cutouts in it for the sink and cooktop. I planned to use no aggregate in my mix, just solid concrete, and use a welded steel mesh (cattle panel) for the interior reinforcement. Is this feasible/possible in your opinion? Thanks!</p>
Thanks, dburns. I really wouldn't recommend doing a very long stretch like that without stress fractures, especially since you've got 2 major cutouts in it.
<p>Thanks for the recommendation. What would you think if I waited to do the cutouts until the countertop was in place?</p>
<p>Very very good post. You've included <br>all the great information in this post. Thanks a million for that. Cheers! </p><p>&lt;a href=&quot;http://www.theclippingpathindia.com/clipping-path-service.html&quot;&gt;Clipping Path service&lt;/a&gt;</p>
<p>brilliant, thanks for sharing!</p>
<p>Your IBLE inspired me to make my own and I have referred back to it many times. It helped me realize that I could <strong>make</strong> something wonderful and functional that I would, in the past, only have hoped to purchase.</p>
Is this house in Chattanooga? I think I saw the MLS on it. Love that neighborhood
This makes sense. The glue gun to the nose does not. LOL. Awesome thanks for posting.
I agree. Indeed Solid Countertops are strong, non-porous and has wide range of designs as well. Will definitely use it for my <a href="http://www.myinstalledcountertops.com" rel="nofollow">Kitchen Counters</a>.

Looks great. I noticed some coins embedded in the top. How did you wet grind the concrete without grinding off the images on the coins as well?
Cheng Pro-Formula mix uses Quickcrete 5000 Commercial Grade, Can I use white Portland cement? What would the cement - sand ratio be? I want to use white Portland cement for a truer color when I add color.
Good illustration. One question about crushed glass. You said we could crush our own glass, is this a special type of glass or just my regular "Ice house bottle". If it is the regular glass, will not end up being dangerous once on the counter. Please advise on this, i will try this by the end of next week.
You can use any crushed glass - remember, the glass will be exactly the same level as the top since the countertop is poured upside down. If the mix is vibrated properly, the cement will fill in any voids around the glass. Then you will be grinding and polishing it all down, so it's all smooth.
Do you have any hints on how to clean the labels off glass that's already been through the crusher at the recycling center? They'll give me all the glass that I can use, but it's still got the labels on it. <br>Thanks for the great instructable!
You can get label remover from a brewing supply store. <br> <br>I use dish soap and &quot;oxi clean&quot; when I need to remove labels. <br> <br>If it is before the crushing I pour &quot;oxi clean&quot; into the dish washer and run the bottles through. <br> <br>Remember to remove the labels that have fallen off before your wife tries to use the machine again. <br> <br>You might try an over night soak of hot water and &quot;oxi clean&quot; and dish soap for your crushed glass and then a rinse off with a hose the next day.
soak the crushed glass in diesel, this will destroy the glue of the label. then in a bucket wash with detergent and rinse in a sieve. if there is still paper and glue then simply get a sheet of fine steel mesh or metal sieve and hold it over a flame to burn it away. then wash again.
Don't know if this will help but I use Goo Gone, it will remove labels, glue, chewing gum etc. You can buy it almost anywhere. <br><br><br>http://www.googone.com/<br><br>
This is probably to late to help you, but for anyone who's worried about super sharp broken glass, cleaning it, etc. just get a bag of sand, mix it with the glass, and run the mix in your cement mixer for a few hours. this should knock off / round over the sharp edges and clean off any labels/residue on the glass. obviously, the longer you let it run, the more rounded it will get.
