tutorial: concrete countertops

 

 

Here are the “counters” we have been living with for the last few months since we installed the cabinets. Yes, that’s just plywood. Being a foodie who loves to entertain, this was definitely a challenge to keep clean on a daily basis. If you look closely enough you can probably see oil drippings and wine stains.

In customary Harpole fashion we absolutely refused to spend anything anywhere near the $50-95/sq ft price tag for countertops. Our solution? A whopping $300 total for supplies for concrete  countertops! But! There is good news and there is bad news, friends. Good news was that we had an outstanding favor for Bryce doing taxes for our concrete artist friend, so we traded for his artistry. Bad news was that there were HOURS AND HOURS of Bryce-labor and a really big mess. Thank God IKEA sends out their cabinet doors with a protective film on the door fronts.

Most people do a project like this before they install the lovely sink, but we are living in this kitchen as we build, and we had to have water.

Even with all this wrapping we still got concrete everywhere. And Bryce really liked to use my lovely stovetop (UNCOVERED) as a place to set his tools!

Here’s a breakdown of our process.

Atop the plywood goes metal lath. It’s basically mesh. It can be found in any hardware store; we went local as always. This strengthens the concrete poured over it.

Then Bryce pulled his first all-nighter of about 9 in a row and poured basic Portland cement mixed with playground sand. This builds a substructure for the finer cement. Let me insert a very important fact pounded into my head by my dear old dad – cement is merely powder. It is not the hard stuff you walk and drive on every day. Concrete, on the other hand, is the hardened substance of cement mixed with water. Get it straight or my dad with correct you!

Our artist friend Charlie Barr, with whom we traded services came over for a Saturday and worked his magic with finer cement, a little silica, and some very fine sand that had gorgeous sparkles. When the sun hits the counter like it does every day for hours, you can see the sparkles. Lovely! Charlie (artist friend) pasted this miracle mixture all over Bryce’s first slab of concrete (see, now it’s concrete because his cement mixture hardened over night).

Round undermount openings are tricky for hand-trowling cement countertops

 

 

Much to Charlie’s dismay, we installed a rounded undermount sink instead of a straight square opening. Harpole’s wouldn’t have it any other way than working with the most challenging angles! But he filled in the sections beautifully.

Here is the countertop today. Bryce just about killed us with pulling another all-nighter pouring poly-urethane every two hours for EIGHT LAYERS! This almost fumigated us out of the house! He couldn’t keep the windows open too wide to air because he didn’t want the night bugs flying into the light and dropping. Screens were installed last weekend.

We still have to sand this layer to rough up the high sheen and then add one more chemical who’s name I can’t remember, and we will be done! We had to stop at this point because I had a house full of family and I couldn’t deny my foodie fam from cooking! Sorry for the poly-urethane nightmare headaches, Sis!

Stay tuned for final countertop photos! I am on the search for lovely backsplash ideas, so please post any suggestions!
