EP. 19 diy overlay concrete countertops


Today on Modern Builds, we're making concrete countertops using the skim coat overlay method.

SUPPLIES:

Concrete Mix: http://amzn.to/1mSvYy5

Sealer: http://amzn.to/1R9cHUb

Carnuba Wax: http://amzn.to/1R9cNem

TOOLS USED: 

Sandpaper

Trowel or Putty Scraper


 

STEP ONE: Mix It Up

First, Mix a batch of Henry Feather Finish to pancake batter consistancy.

STEP TWO: Spread and Smooth

Before I worried about getting the surface perfectly smooth, I first spread the concrete across counter. Once it was distributed, I went back and smoothed the concrete out, cleaning my trowel with each pass.

STEP THREE: Sand it Smooth

After the each coat dried, I sanded down the high points with 80 grit sandpaper, making sure to use light pressure.

STEP FOUR: Repeat

I applied 5 coats before my final coat. 

STEP FIVE: Final Coat

Before my final coat, I sanded the entire surface with 150 grit. I used a slightly thinner final coat.

STEP SIX: Fix the Mistakes

I didn't make my final coat perfect, and I'm going to assume that most of you who also haven't worked with concrete much won't either. I filled my trowel marks with concrete.

STEP SEVEN: Sand, Sand, Sand

After the patches dried, I sanded the countertop starting with 80 grit, then 100, 150, 240, 360, 480, 600, and 900. After the final sanding, the counter should be smooth like a polished stone.

STEP EIGHT: Seal and Wax

I used a concrete sealer on the counters. I put five coats on and then put a couple of coat of carnauba wax.


That's all there is too it. This is a somewhat long process, but creates an incredible end product. Thanks for checking it out and if you have any questions, either check out my contact page, or leave a comment on my Youtube video.
