Pour a Concrete Countertop for an Outdoor Bench

Pour Concrete into Countertop Form

When I think I have it thoroughly mixed I pour the wet concrete into the form.

Even though I’ve added the citric acid and used cold water to extend the working time, I get to the next batch right away. Planning is key here. I have to have everything ready to go for quick, consecutive batches.

Vibrate to Settle

I vibrate the form with a reciprocating saw to bring any bubbles to the surface.

Add a Wire Grid for Reinforcement

Once the mortar mix begins to thicken I lay in a wire grid for reinforcement.

This is a heavy gauge galvanized hog panel I bought at my livestock fencing supplier. I find small bolt cutters to work well for cutting the grid to size. 

Oh NO!! RAIN!!

My nice sunny day changed unexpectedly and dark clouds with rain rolled in. I had to put together a quick improvised tent to keep the rain off the wet concrete.

Max came by to keep me company for a bit.

This is kind of funny as I will need to wet the concrete once it fully solidifies, warms to the touch, and developed a white haze. Turns out that began to happen just as the rain stopped and the sun came back out. Go figure huh?

The SUN is BACK!
