Concrete Countertops-?

Question

Have you ever tried this? I've seen in done on t.v. and have DIY instructions BUT is this really complicated?

It says "intermediate" as for the level of difficulty.

Thanks for any advice or input!!

Answer 1

Well... it isn't hard, but it ain't easy.  Build the forms out of melamine, do a nice silicone bead around the seams, mix the concrete, pour it in, add some wire, screed off the top, pound on the mold to get rid of the air bubbles, cover it with plastic, and let it dry.  That's basically it, except you have to make sure the form is the correct dimensions, you don't get any bubbles, and you don't break it trying to get it into place.

Answer 2

the problem with DIY concrete countertops is they need to be poured in place. Use wire and rebar to reinforce and the mixture is a little different then concrete for floors. Call a professional and ask for advice, most will be willing to give it. Good Luck!

Answer 3

you can make the counter top in your garage..get the dimensions you need and create a "form" to those dimensions....example:  think of making a square box with 2x4's around the sides and plywood on the bottom...you would then pour pre mixed kwikcrete (easiest and cheapest route to go but this does have larger stone in it.)  When choosing your form though, check the surface of the wood because when you pour the concrete, the sides will have the same look (grain) as the 2x4's (or whatever you use) the bottom isn't important as long as it is level because no one will see it...after you pour the concrete in there, you might want to vibrate the concrete...(you could use an old kitchen hand mixer or something) this gets the air bubbles out...just use it in a few areas for about 5 sec., then you want to "float" the surface....you can use a piece of wood (the same width as your counter) and slide it from side to side to smooth...let the counter "set"...if you want a textured finish, wait for it to set but still tacky and use a wire brush on it to reveal a stonier texture & look...when it is hard...break the form away and voila.....a concrete counter...(once it is out of the form, you can use whatever side you want as it can be turned over)..best of luck!

You have to build the forms and pour the concrete.  Be sure to level the top of the slurry in the form because this will be the bottom when they are put on your cabinets.  You cabinet tops will not set straight if they are not flat and smooth.  Make sure to caulk the cracks in the forms and vibrate the forms with a sander to get all air bubbles out.  They look great on the cabinets but they ARE hard to lift and put in place (very heavy).  Lastly, make sure you measure well to get the right fit, and remember, in the forms you are looking at them upside down.
