It’s been 6 days since the first pour and 5 days since the back-splash and void fills. I was going to wait two weeks but seeing the undercuts gone, after chipping away a little every day, I got excited and removed the forms.
Things are starting to come together. Instead of drilling out the faucet hole after the concrete hardens, I inserted a 1-1/4” dowel and 2-1/2” counter sink. It works fine but here are some things I’ll change next time. First, the thru hole should have been 1-3/8” to be standard (I think). Second, I wish I had just drilled it to give me location flexibility. I based my dimension on my current sink but I don’t like how close this faucet is to the edge of the sink.
Drilling out does have a drawback I’ll have to resolve. The faucet threads are too short to be used on a 1-1/2” thick counter-top. The counter-sink is necessary unless the faucet can be refitted with longer threads.
The above image shows; the form before the pour, the chipping away after the pour, the plug removed, and the plug still in the concrete after unscrewing it from the rest of the form.
This image shows my biggest problem area. This confirms my fears mentioned in one of my previous post about flat out forgetting (panicking) to push concrete up in this area. I used my orbital sander to remove paint that preferred to stay on the concrete. Worked great but I didn’t like the slurry around a tool not intended to be wet.
I’m really happy with the results. The back splashes are ready to be polished. The pits in the counter-top and sink need to be filled. I was going to use contrasting white grout but after seeing how black the back-splashes are, I’m going to switch to black grout to tie in them in aesthetically.
Right now, I’m back to curing but with the top-side up. I think I’ll take a break for a while before I start mixing up my grout. Reason… see previous post.
One last thing. I think it’s important to reiterate the mixtures that gave the shown results.
The Sink and Counter-Top
Batch 1 – 1 80# bag Quikrete Counter-top Mix, a little more than 1 gal of water
Batch 2 – same as Batch 1 but add 1 Quikrete Charcoal Concrete Die
Gently fold together
1 60# bag of sand mix (sand and cement), 1 Quikrete Charcoal Concrete Die, 1 bottle of Acrylic Fortifier. (don’t know how much but there is only one size), Water.
