How to patch and get smooth edges to your concrete countertop.

Some people like when the concrete countertop edges have the rough concrete look and some like to have the smooth edges. Here are some hints and tips how you can get the edges you want.

When you are doing a concrete countertop, one of your worries might be, how the edges look like when you take off the molds. The holes in the edges  occur because of the air in the concrete. If you want egdes to be perfect or without any bigger holes in them you need to vibrate the moulds when the concrete is still wet. The vibration is easy to do, almost everyone has a sanding machine at home. Vibrate the countertop form edges with the sanding machine, it will give you a better chance to get the smooth edges you want. As a rule for vibrating the edges, the time you think that you need to vibrate the edges, multiple that by two or three times:) Then it should be enough.

But there is still a chance that there are some holes after you have vibrated the edges. This has been a concern for me as well, before I found the Z Counterform products. The Counter Patch is made for this kind of issue.  When the concrete worktop  it has dried enough so that the molds can be taken off, you´ll finally see the countertop edges. If there are still holes you want to get rid of, with the counter patch you can easily fill up the holes on the worktop. Only thing you need is the Counter Patch, rubber gloves and some sandpaper.

The second option is to use Liqui Crete mix. It contains acrylic fibers and a special mix that forces the air out of the mixed and poured concrete mix.  The special mix… first time I used Liqui Crete, I could not believe how well it works. It really is a unbelievable product. At the first countertops I ever made, the vibration took a really long time and I could not predict what would the outcome look like. I visited Z Counterform USA, owner and inventor Ed Baldoni, who trained and introduced me to this product. We made a countertop at the training with Liqui Crete. We were almost done with it and I thought we should start to vibrate the edges, well we kind of did it.. but only about a minute and by hand. We used the handles of a screwdriver and tapped the Z Counterform edges gently, really for about a minute. Then we left for a lunch… Really easy and fast job, comparing it if I would have needed to vibrate the edges with sanding machine. Acrylic fibers in the mix, give more durability to the countertop. if you are planning to make a worktop or an island with an  overlay, it would be a good thing to use Liqui  Crete.

I say to customers that , the Liqui Crete saves a lot of your time. You don’t need to vibrate the edges (well just few minutes, by hand) and no patching is needed when the moulds have been taken off. The other benefit, it gives extra support for the countertop because of the acrylic fibers in the mix. The third benefit is, that you get the smooth edges easily. Here is our video on the Liqui Crete if you want to see it in action.

All of these methods work really well. So, you´ll have your dream countertop. All you need to do is to choose the look, rough or smooth. You can have it as you want it. To get the smooth edges it depends on the budged, how  much money do you want to spend on your countertop.  And how much time do you want or like to spend working the worktop? Liqui Crete will lift the cost of the countertop, but I divide the cost with the time I´ll spend more finalizing the worktop.  In either case, the price of the countertop will be affordable and it will sustain a long time. Concrete has been known to last more than 200 years, so in that time you´ll have to change your kitchen cabinets few times:)
