After much research I have decided I would like to build my own concrete
countertops. I like the whole modern look so I am going for a simple 1.5
inch cement gray counter. Rather than
casting and trowleing them in place I plan on casting 2 x 4 pieces upside
down in a melamine mold and then piecing them together on my cabinets. My
understanding is that makes for much easier process and smoother
top since the bottom of the melamine is nice and smooth to begin with. The
few grout lines I have are not a big deal. After doing a lot of research on
the web I still have a few questions I need some help on:
1) Quikrete has a product called Non Shrink Precision Grout. Their website
recommends this for counters since it will dry
to 3000PSI in 2 days and 8000PSI in 28 days. A few questions:
1) They recommend to blend this to a syrupy consistency - this makes
it easy to pour and reduces makes a smoother finish - any experience with
2) They say to use this without rebar or reinforcement except for
around the sink, is that correct?
3) I have seen a few negative comments on this particular product.
Any experience out there in using this product for counters?
2) If I use the grout mentioned above (or other concrete mix) and want to
use reinforcement, can I use simple chicken wire I can buy at Lowes for
this? Or do
I have to use the real rebar stuff?
3) I want to use the non shrink grout because it sounds like it makes a
smooth finish, especially since I am casting them upside down in a mold. If
I do need to sand
can I just use regular sandpaper and an orbital sander while the concrete is
still 24 -30 hours fresh? I am not looking for a glass finish, just smooth
4) Any recommendations for a sealer.
