Concrete Sink Project Part Two

Well if you read the first part of the series on the concrete sink project you know know that I had just poured a slab base for my cabinet to put a concrete sink in.

This is my first attempt at making a concrete sink and I am blogging about it in parts.

In this post I wanted to post several pictures of the cabinet as it is now completed. Also the sink will take the shape of a guitar. I worked on the guitar mold for quite some time now and tonight I completed it.

The cabinet was a simple build with 2×4’s and later I put older would on the facing of it so that it looked rustic.

The guitar mold was fashioned out of the pink 2 inch thick foam from Home Depot. I used 3 layers of it glued together. I then sanded it slightly and coated it with plaster in 2 coats then sanded it down to a fine finish and coated with a two part epoxy. The epoxy should allow me to reuse the mold on future guitar sinks later on.

Quick little funny, tonight as I was looking at the mold and marveling at the glossiness of it and daydreaming about how the sink would look, I noticed that the 2×4 boards I was using to keep it off the work bench was now glued to my mold. WHAT WAS I THINKING !!!!!???!!!

I quickly reacted and tried hard to get the boards a loose from the mold trying desperately not to destroy my hard work.

I succeeded with minimal damage and learned a valuable lesson. I think I can fix the rough edge I made. Everything should be ok.

Here are some pics of the cabinet base.


Here is a small video of the concrete sink mold getting fabricated.

Stay tuned for the next installment Concrete Sink Project Part Three

Did you use a release spray/wax to make the guitar mold release from the concrete easier?

Yes I used WD-40 and wax

I would love to see a video of you mixing a pouring the concrete. I have also been following the videos and the guitar sink looks awesome!

Hope you post the new video!

Mixing and pouring concrete with the guitar mold. I left that part out!

I didn’t “pour” this one. This is sprayed using a spray gun. This is GFRC or glass fiber reinforced concrete. Sorry, no video of spraying.

The video isn’t linked, and is set to private. Interested to see how you incorporated the guitar into the mold.
