Pouring A Concrete Sink

And versatile to boot.

Pouring a concrete sink.

Cut one piece of melamine the same size as the finished countertop. Choose a high strength concrete mix it doesn t need to be a countertop mix but that variety is also available. The concrete forms are made of 3 4 melamine boards. Melamine is readily available at home centers and lumber yards has smooth surfaces that don t imprint on the finished concrete and won t de laminate.

Consider concrete tool rental for your big project. This concrete farmhouse sink not only looks good but is also hard working with two deep bowls and simple maintenance. Clean the entire form with denatured alcohol to get rid of any excess silicone and debris. Then add a thorough coat of a release agent spray to help prevent the concrete from sticking to the edge liner and sink knockouts.

Work quickly when pouring concrete countertops but don t be sloppy or careless. The box is 2 wider than the sink mold on all sides and sloped in the front to follow the slope of the sink mold. Using a sink mold sold here you can place the mold as part of your form work and pour the sink as part of the countertop this is a great option for overall strength of the concrete. On the table saw rip four strips of melamine 2 1 4 wide and long.

Making a large hole as in the above 2 sink options greatly increases the overall weakness of the concrete piece and stress cracks are common around sinks. Don t mind that fancy copper patina in the sink. There are a few things you need to understand before picking concrete countertops as your new counters though and that is one they are not a uniform color there are variances and the more you need to sand on them after pouring the more they have variation because of the aggregate that shows through.
