Re: gunite pool on recently purchased home- Resurface Options?
most likely my forever home. which is where my post stems from lol. I absolutely love the house, layout, subdivision, the neighbors, and the pool!
OK, me too. I based my decision about which surface to choose on longevity, and my projected lifespan. No joke. There are too many variables at play to make a really reliable decision based on that, but that didn't stop me! Here's how I figured it out. I made some wild assumptions, but you can narrow those down if you choose to do more research than I did, which wasn't all that much.
I figure if I live well, I might get another 30 years. I'm also assuming I'll be interested in swimming in my pool that whole time, or at least be interested in enjoying others swimming in my pool (kids, g-kids, gg-kids, etc).
I also figure that I'll be willing to do the very best I can, the whole time, to take care of the surface of my pool (by maintaining great water conditions using TFPC). I'll either do so myself, or coerce and manage someone else to do so if I get too feeble (kids, g-kids, gg-kids, etc).
OK that's two variables. What about feel? What about cost? Those were the only other variables I considered. I owned plaster. Love the feel. Plaster was the cheapest finish I considered. The plaster longevity estimates are pretty broad, but I'd heard 5-15 years. Mine made it six, due to some extreme conditions. Some claim plaster pools of 30 years or more, but there's no knowing how that was achieved, and not something to bank on. I didn't think I could even hope for that possibility. I figured the 5-15 numbers were based on the average way pools are taken care of, which is not all that great. I learned that the early demise of plaster is very much influenced by poor water conditions. So let's say I do an extraordinary job of taking care of plaster, and stretch the estimate to 15-20 years. That means, best case, I'd be looking at two plaster jobs, one now, and one more someday. And I don't think it's a stretch to assume a plaster job in 20 years will cost twice as much (that's probably very conservative). So (for my pool) that's $5500 now, and another $11K down the road, let's call it $20K total to cover contingencies and a more realistic inflation amount. For a very nice finish now, that won't be a all that great as it reaches end of life (the plaster's, not mine!). Pool surfaces get rougher over time, until they fail beyond what one can tolerate (roughness, chipping, flaking, etc).
So the only other surface I considered (due to cost) was pebble. I think that is the next type of surface in line, cost-wise, from the available list. They go up in price from there. Definitely not as comfortable as plaster. Appearance, to me, was a wash, I like the look of each equally, maybe pebble a little more, I like the pebbles. Pebble is estimated to last 5-10 years longer than plaster (again, no science to either set of numbers, all anecdotal, off the internet). And let's again assume I can stretch those pebble numbers by applying diligent care of the water, so 10-15 years longer? Which means, theoretically, I could stretch the lifespan of pebble to 25-35 years. Again, this is using some wild assumptions, but at least feasible. Which could then mean I'd only have to pay for one more surface in my lifetime. And that's about $7500 now. Way less than half the cost of plaster over my lifespan. No inflation figure to consider. So I went with pebble. If nothing else, pebbles give me a better
possibility of paying just this once, over plaster which is more likely to fail in my lifetime. You could do similar math with the other available surfaces, and their claimed projected lifespans.
This could all backfire (probably will). Maybe I could have gotten one of those 30-year plasters, and had a much more comfortable finish the whole time. Or maybe my pebble will poop out in 20 years and I'll have to pay for another surface anyway, which means I blew the $2K extra I just spent to buy pebble. There's no way to know, so I took a stab, based on some unprovable assumptions, and rolled the dice.
If you're 80 years old, or money is no object, get plaster. If you're half that old, and need to watch your dough, break out the calculator, gather your own surface longevity projections, and do the math...
Sidebar: if you're fussy about the look of the finish, get white. It'll stay true to its initial look the longest. If you like a darker pool, be prepared for the surface's appearance to degrade relatively quickly, and get worse over time. My new pebble, at less than a year old, is already sporting slight color variations (mottling), which don't bother me at all, I kind'a like that look. But that is pretty typical, and I expect it will continue to degrade (the looks, not the feel so much). My previous 6-year-old plaster was heavily mottled and had wild color variations (though some of that was due to calcium scaling deposits). This is true of at least plaster and pebble, you'll need to research a bit to determine if the other types of available finishes have this issue.
Looking forward to hearing what you decide...
