How I Updated My Cultured Marble Sink

Bathroom sink makeover using concrete for a new modern chic look.

Remove Hardware

The first step was to remove the old outdated hardware and clean away all the gook around it.


I also taped the wall around the sink to prevent the concrete from going where I didn't want it using painters tape.

Sanding.

I sanded the surface using a 120 grit piece of sandpaper with the hand sander to rough up the surface.


After sanding, I wiped away the dust using a dry cleaning rag.

Applied Concrete

After roughing up the surface, and cleaning it, I missed the concrete powder with water to the consistency of cake batter.


I applied it using a drywall knife on the flat surfaces and my finger inside the bowl.


Between layers I allowed it to dry for at least 12 hours, although it could have been much less time. I just did it in the evenings over the course of a couple days.


I did a total of three layers, sanding with my hand and a sanding block in between to remove any imperfections.

Smoothing

I did a final sanding to smooth away any imperfections using a 220 grit sandpaper. Depending on the level of imperfection you can use your sanding block or hand sander, depends on how smooth the application went.

Seal

After sanding and cleaning away all the dust. I used a Quikrete concrete acrylic sealer to seal the concrete and reinstalled new hardware for a more updated look.

    Im considering this for a bathtub. Larger scale but the same base material. Do you think that would work and yes I want a textured floor in this tub for traction.
