Pool Deck Project

 

Several summers ago, we were swimming in our pool and I noticed a reddish brown stain on the wall in the deep end. I tried to scrub at it, I poked and prodded at it, and couldn’t figure out what it was. My pool serviceperson said “Well, you do need to resurface your pool”.  The 28-year-old plaster was crumbling and eventually would get into the pump system, ruining it. That mystery stain? Rebar coming through the plaster and creating a pretty magnificent rust stain.

The financial worry felt like a ton of bricks had fallen on my head. How much was this going to cost? Why the heck did I allow myself to buy a house with a pool? Of course, the frugal part of me was wondering if I can do it myself… HA! Nope. Long story short, we just now signed the contract for the resurfacing job to get done. Which led to the inevitable Backyard Makeover Domino Effect. After the initial sticker shock, we began to get super excited- no more decades-old 80’s pool/ pool tile! Maybe we CAN transform this dumpy backyard into an oasis! Maybe we can finally enjoy being OUTSIDE!

After cleaning up and getting rid of old backyard crap, we decided to figure out what to do with the concrete pool deck. It is exposed aggregate, which is beneficial because it helps prevent slipping when wet. So whatever we did, it had to maintain that same slip-resistant property. We couldn’t afford for it to be ripped up and replaced, and besides having a few rust stains it was in great condition with little to no cracks.

Concrete staining or painting would need to be sealed, which could get slick when wet. I did tons of research and decided to go with a product found at Home Depot, called Behr Granite Grip. It comes in 2 colors, gray and tan that can be tinted to several different shades. We had ours tinted to Copper Marble, and got two big 5 gallon tubs.

We chose this product because of the ease and cost. After prepping the concrete, you simply paint it on. I wasn’t sure it would work on exposed aggregate, so I bought a small can and tested it on my side walkway. It worked beautifully!

As part of the prep, the concrete needed to be thoroughly cleaned. There were several options I read about online- TSP, muriatic acid (which was pretty frightening to read about- it’s hydrochloric acid), Simple Green, and commercial cleaners and degreasers. The surface must be cleaned, scrubbed, scrubbed, and scrubbed again- otherwise the color won’t adhere properly to the surface, and can cause discolored areas.

Moreover, the surface needed to be etched. It took me time to figure out what etching was (finally just googled it- could’ve saved me time if I’d thought of that from the get-go). Etching basically roughs up the surface so the concrete will accept the paint or stain. I sent an inquiry to Behr customer service to see if exposed aggregate needed to be etched since it’s rough to start with. The answer is YES.

I finally came across a product at Home Depot from Rustoleum, which is one of my favorite DIY products. It’s a concrete and masonry cleaner and degreaser. It has to be diluted, so follow the directions on the container. As for etching, well, here’s where my newbie-ness comes into play. Rustoleum has a cleaner and degreaser, and also a cleaner and etcher (with added components to rough up the surface at the same time as cleaning it). The containers are almost identical. So I actually ended up cleaning the concrete, then having to clean and etch.  Note to all you DIY-ers out there- just get the Clean and Etch.

After applying the cleaner/etcher, you have to scrub with a long-handled scrub brush, using about 10 million tons of elbow grease. Trust me- my arms and shoulders were super sore the following few days! Rinse it a MINIMUM of three times, and let it dry. The surface should feel like 150 grit sandpaper. Just keepin’ it real though- I don’t know what 150 grit sandpaper feels like compared to other grit sandpapers, so I just felt it and yup, felt like sandpaper. Done. Just needed to keep the kids and a crazy dog off of it for a day.

We did not have any cracks or chips to repair, so if anyone out there has them, you would repair the cracks after the etching. There are a couple products out there from mixing your own concrete (in a small bucket- apply with trowel, putty knife, etc.) or premixed in a sort-of squirt bottle for filling cracks. Let it dry and sand down lumps or ridges.

Here’s a few pics of the concrete after cleaning and etching. There were rust stains on the concrete which did not come up. I didn’t worry too much about them because 1) the color we chose is similar to rust-color 2) they were small 3) I was too lazy to go out and buy the recommended Krud Kutter to try to get it up.

 

The next step was to tape off the areas we did not want painted. We used painter’s tape for concrete- which I never knew existed and probably have picked up in the past on accident and ruined an interior wall or two, but whatevs. It adheres well which I needed. We taped around the pool coping and bricks, and covered over the additional copings (is that what they’re called?) and pool deck drain (the horizontal black lines in the picture). We also taped over our current pool fence holes- we had the fence replaced a few years ago and new holes were drilled- the old ones we left uncovered.

Now the fun part. Well, not so fun. Keeping two young kids away from wet paint and a wide open pool was not fun OR easy. Not to mention the numerous interruptions we had  to break up fights going on inside. Regardless, we started by painting the Granite Grip with brushes alongside the taped areas and borders. This was super exciting- I knew from the first brush stroke I was going to love the color!

 

Then came the rest of the surface. Behr is pretty clear that one must use a 1/4 inch adhesive roller for the Granite Grip. We got a couple long-handled rollers as well. The problem: Not easy to get the first two coats on with a long handled roller on exposed aggregate. More pressure is needed to get the product evenly spread, so we ended up on our hands and knees covering about 800 square feet (just a guess) of rocky, sandpapery, jagged concrete. I’m not bitter.

 

A note about the first coat: The first coat of the Behr Granite Grip is NOT what the final color will look like. Behr is very clear about that. The second and subsequent coats are more accurate. We did 3 coats after the initial border-painting. Also, the surface became smoother after multiple coats. On the last coat, we were able to use the long-handled roller, giving our backs, butts, and quads a break!

This product dries fairly quickly- ok to have light foot traffic after 24 hours, can move furniture back after 72. We had to take the dog on walks and despite my neighbor behind me spraying a hose over my fence onto the newly painted surface, it went off without a hitch. Took us about a day to complete (after the surface prep).

And now, the final look! We keep looking dreamily out the window….and planning the next project. =)
