Is your pool starting to feel more like a piece of 40-grit sandpaper than a luxury oasis? Have you noticed that your swimsuit is snagging or, worse, your kids are coming out of the water with scraped toes? If your backyard retreat is losing its "pop," it might be time to talk about the heavy lifting of pool ownership: resurfacing.

In the Treasure Valley, we deal with some pretty wild temperature swings. From those 100-degree Boise afternoons to the sub-zero Meridian nights, our pools take a literal beating. After 25+ years in the industry, we’ve seen it all. But what actually happens when a crew shows up to "replaster" or "resurface" your pool?

It’s not just a quick coat of paint (please, never paint your pool!). It’s a highly technical, multi-stage engineering project. If you’ve been curious about the pool resurfacing process, grab a coffee, and let’s dive into the technical nitty-gritty of how we bring an Idaho pool back to life.

1. pool draining: More Than Just Pulling a Plug

The first step sounds simple, but it’s actually where things can go sideways if you aren’t careful. We use high-volume submersible pumps to move thousands of gallons of water. But here’s the kicker: we have to be mindful of the Boise water table and local drainage regulations.

Safety is always number one. We don’t just dump water anywhere; we ensure it’s routed correctly to prevent flooding your neighbor's pristine lawn or causing issues with the local storm drains. We also have to watch out for hydrostatic pressure: that’s the fancy term for the water pressure in the ground outside your pool. If the groundwater is too high and the pool is empty, the whole shell can actually "pop" out of the ground like a boat. We check for hydrostatic relief valves to make sure your pool stays exactly where it belongs.

2. Surface Prep: The "Make or Break" Phase

If you’ve ever lived through chip seal season in Idaho, you know that the new layer of oil and rock is only as good as the road underneath it. Pool resurfacing is exactly the same.

Once the pool is dry, we start the "demo" phase. This is the loud part! We use jackhammers to undercut the tile line and around all the "penetrations" (that’s industry-speak for your lights, returns, and drains). This ensures the new finish has a smooth, flush transition rather than a bulky lip.

Next comes the surface profile. We often use hydro-blasting at 40,000 PSI or traditional chipping to remove the old, delaminated material. We’re looking for a solid, "toothy" surface. If we leave any loose or hollow spots, the new finish won’t stick, and you’ll be calling us back in two years with "bubbles" in your plaster. We don't want that, and neither do you!

3. The Bond Coat: The Secret Sauce

After the pool is stripped and cleaned, we apply a specialized bonding agent. Think of this as the ultimate primer. This material is engineered to create a chemical and mechanical bridge between the old concrete shell and the new interior finish.

Why does this matter? Low permeability bond coats not only help with the adhesion of your new finish, they minimize the effects of the substrate on the appearance of the pool finish by reducing hydration issues.

4. Structural Repairs and "Pool Cancer"

Before we put the pretty stuff on, we have to fix the "bones." During our swimming pool inspections, we often find cracks or what we call "pool cancer": rusting rebar.

If moisture reaches the steel reinforcement inside your pool shell, the steel oxidizes and expands, popping the concrete off from the inside out. We cut out the rusted steel, treat the area with anti-corrosion agents, and patch it with high-strength waterproof cement. We also address any structural cracks using "staples" or specialized epoxy injections to ensure the shell is watertight.

5. The Main Event: Pumping and Hand-Troweling

This is where the magic happens. Whether you’ve chosen a classic white plaster, a quartz aggregate, or a premium pebble finish, the application is an art form.

The material is mixed on-site in a specialized rig and pumped through a large hose into the pool. Then, our skilled artisans (and we really do mean artisans) jump in. They use hand trowels to spread the material across the floor and walls with incredible precision.

The precision of plastering cannot be overstated. They have to work fast enough that the material doesn't "set" before it's smooth, but carefully enough to ensure there are no trowel marks or uneven thicknesses. It’s back-breaking work that requires years of experience to master. If you’ve opted for a more modern solution like ecoFinish, the process is different (thermal spraying), but the requirement for a perfect prep remains the same.

6. The Exposure (For Pebble and Quartz)

If you chose a pebble or quartz finish, there’s an extra step. Once the material is applied but before it’s fully hardened, we "expose" the aggregate. This usually involves a delicate water wash or a light acid wash to remove the top layer of "cream" (cement paste), revealing the beautiful stones or crystals underneath. This is what gives your pool that amazing texture and sparkle.

7. The Final Fill and the "Critical Month"

Once the crew finishes the floor, we immediately start the fill. Why the rush? Because new plaster is "thirstier" than a hiker on the Boise Foothills in July. It needs to cure underwater.

The curing process is actually a chemical reaction called hydration. If the plaster dries out too fast in the Idaho sun, it can "check" or develop tiny spiderweb cracks. We often wrap the nozzles of the hoses in clean rags to prevent the water pressure from "boring" a hole into the fresh plaster.

Pro-Tip: Do not turn off the water until it reaches the middle of the tile line! If you stop it halfway, you’ll get a permanent ring around your pool.

8. Water Chemistry: The Science of Longevity

You might think that once the pool is full, you’re ready to cannonball. Not so fast! The first 30 days are the most important in the life of your pool. As the cement cures, it naturally raises the pH of the water.

You (or your pool maintenance service) will need to:

1. Test the water daily: Balance the pH and alkalinity to prevent scaling.
2. Brush, brush, brush: You’ll need to brush the entire surface twice a day for at least two weeks. This removes "plaster dust" and helps the finish stay smooth.
3. Hold off on the salt: If you have a salt system, keep it off for 30 days. Adding salt too early can damage the uncured finish.

Why Boise Pool Owners Trust the Pros

Can you DIY a pool resurface? Technically, you could buy a trowel and some cement, but we wouldn’t recommend it. Between the specialized pumps, the chemistry involved in the mix, and the sheer physical demand of the work, it’s a job for experts.

At Idaho Pool Remodeling, we’ve spent decades refining these pool replastering steps. We know exactly how to handle the unique challenges of our local environment. We don't just want your pool to look good for the photo: we want it to last for another 15 to 20 years.

Are you ready to stop worrying about rough surfaces and start enjoying your backyard again? Whether you’re in Boise, Meridian, Eagle, or Kuna, we’re here to help.
