How To Make Concrete Countertops by diypete.comI hope the tutorial will help and inspire you to try out a few concrete projects! You will need to invest in materials and perhaps a few new tools, but you’ll still come in cheaper than hiring a professional. Building the molds will take between a couple hours to a full morning depending on the complexity of the counters. Once de-molded, let the concrete continue to cure for another 2 days to build up strength.

Concrete counters have a very earthy and organic look to them. That means concrete counters can stain if acids, oils, or wine sits on the concrete long enough. Concrete counters will have character, and blemishes or voids can be noticeable. If you like the industrial look of countertops, or their rustic look, then concrete counters are something you will like. Many folks look at some of the stains and say it adds a patina over time that adds to the character. There are traditional mixes as well as more expensive mixes with special additives. Quikrete countertop mix has much smaller aggregate that is the size of sand. The countertop mix has a plasticizer additive which makes it so you need less water to get a flowable mix. The big disadvantage of the countertop mix is its working time. I do not recommend building counters for your first concrete project. Once you have a table or two under your belt, you’ll have some priceless experience that will help tremendously with your first concrete counter project. If you want to see the aggregate in the concrete counters then you’ll want to polish the concrete. You’ll need to polish the concrete if you want to expose crushed glass. You won’t expose the aggregate with a 200 grit pad and it is much quicker and in my opinion easier to get a nice looking finish by a beginner. Make sure it is centered and exactly where you’ll wan the sink to be. Cut the sides for the concrete counter molds on a table saw. The extra 3/4 of an inch connects to the base portion of the mold. A jigsaw will also work, but getting the larger cuts perfectly straight is a bit harder.Keeping the larger side against the fence will help get you the straightest cut. A belt sander can help with this process if you are not able to cut the corners with a scroll saw or jigsaw. A round over bit on a router does a really good job creating the corners. I like to use stucco tape because it has a smooth finish and adheres nicely. I like to have about an inch of space between the perimeter of the reinforcement and the sidewalls of the concrete mold. Here is a look at the reinforcement in place and test fit in each mold. You basically run a beat of caulk, then use the fondant tool ( which is basically a ball bearing on a metal stick ) to round over the bead. The ball pushes the excess to each side, so you can simply peel off the excess once dry. Check the stem length of your faucets to make sure it is long enough to get through your counter. This way the nut can be tightened and secured if you have a shorter faucet stem. Dip your finger in water to help the bead of silicon go on very smoothly. I used a caulk tool for this, but a cake fondant tool would work even better. I centered the faucet hole and made sure it lined up with the pre-cut hole in the metal sink. Let the caulk dry for a couple hours prior to pouring concrete. Coloring can be added during the mixing process if you’d like. Transfer the concrete from the mixing tub or mixer using a couple gallon bucket. You can also use a concrete vibrating tool or rubber mallet to tap the sides of the mold. Then mix of a batch of concrete that will go around the sink. You are in the right place if you are interested in learning how to make concrete countertops for your home.This will save you time, money, and energy with your next countertop project! Concrete counters can be completed within 7 days if the conditions are right. This will vary depending on the mix used, temperature/humidity, and additives in the concrete. Concrete counters can be any shape, thickness, texture, and color. They can be made to look rustic and stone-like, or polished to fit a modern kitchen. This problem can be solved by staying on top of maintenance and making sure a good sealer is used, along with wax. If perfect looking countertops are what you want, do not attempt building your own concrete counters. Cheng concrete sealer for years and it is one of the most well known and popular brands. As long as you don’t leave the acid or oil on too long, you’ll be okay. The smaller aggregate is also nice because you won’t have rock chip-outs on the edges, and an orbital sander can easily create beveled edges if you don’t have a concrete polisher. Concrete counters are an art that does take time and experience to get good at. Concrete counters are a lot of work, but the end results and money savings are well worth it in my opinion. Polishing will expose the rock or items embedded in the concrete because it grinds off the cream surface. Sanding counters will give you a finish with the natural creamy look of the concrete. With wet polishing, you can get a higher gloss finish and can bevel edges etc with ease. Sometimes having the template can help make this process easier to ensure the counters are built correctly. If you are adding a sink, you’ll want to draw around the template that came with the sink. It came with a nice template, but it had a lip on one side with only 1 knockout hole pre-drilled. I use either a table saw or a circular saw to cut the melamine. For 2 inch thick countertops, cut the strips to 2 3/4 inches in width. Attach the sides of the mold using 1 5/8 inch long drywall screws. Work slowly with this process and take a little off at a time. I prefer this method if you can find a bit that matches up with your corner. A light sanding with a drywall screen can help remove any bumpy areas. This is especially important when doing counters with a sink knockout because it will help minimize the chance of cracking. I like to use zip ties because it is super quick and easy, but metal wire works well. Use silicon to attach the sink knockout to the bottom of the mold. If you choose to use the tape method, round the silicon with your index finger. You can either mix by hand or with an electric concrete mixer. Vibrating the concrete helps remove air pockets from the concrete. Let the concrete firm up slightly before adding the reinforcement. I tend to do the majority of the concrete vibrating before adding the reinforcement. Add glass fiber reinforcement fibers into the concrete for around the sink area to help give it additional strength and to prevent cracking.
