framed wall in front of peninsular cabinets is mainly for wiring purposes, but also will cover back of the cabinets. plywood on top of cabinets serves as underlayment under counter tops.
kitchen cabinets all in place. drawers and doors will be installed later. we also started to work on templates for concrete counter tops. i used hardboard material to slice strips and created template that included sink, cook top, faucet and outlet locations. since we are doing counter tops upside down, templates had to be flipped when creating forms.
forms cut out of melamine, with reinforcement and knockout panels in place. steel will be taken out when pouring and put back so it sits in 1/3rd of counter top thickness from the top. it will be actually in 1/3rd of thickness from the bottom when we flip them over.
peninsular piece is huge, it took 6 of 80 pounds concrete bags. after the form was full, we screeded it with 2x4 and let it sit for an hour before hard troweling it. smaller counter top ate 4 bags and side curtain 2 bags of concrete mix. for concrete mix we used quickrete 5000, with addition of super plasticizer. to eliminate micro cracking we added polypropylene fibers.
hard troweling the surface.
all troweled and ready to cure.
as we dont have time to wait a week or so for concrete to cure, we removed forms the next day.
3rd day from pour, we flipped smaller counter top over. the surface is really smooth from melamine form surface and even though we quite vibrated the forms with sander while pouring, there are still little voids that will need to be filled with slurry.
