Gilbert's mix of brand-new plaster and aging lakeside surfaces means acid wash needs vary widely. Coronel Pools matches the strength to your finish and brings the surface back bright.
Gilbert grew faster than almost any town in the country, and the pool surfaces here reflect that. The newer builds in Agritopia, Power Ranch, Seville, and Cooley Station have fresh plaster that has not had time to accumulate deep stains, but the hard water and the open-lot dust still leave a film and a calcium crust that dull the surface. The established lakeside pools in Val Vista Lakes and Morrison Ranch have older surfaces that may have collected years of scale and organic staining. An acid wash strips that buildup away and reveals the clean surface underneath, but the strength and the approach have to match the finish. We tailor every Gilbert wash to the specific plaster condition, because a gentler mix on a new finish and a stronger one on an old surface are very different jobs.
Gilbert's hard water builds a calcium crust on the walls, and the open-lot dust from the newer developments settles into the water and leaves a dull film on the surface. We drain the pool and apply a controlled acid solution to dissolve both. On the newer finishes in Power Ranch and Seville we use a lighter mix because the staining is shallow, while the older Val Vista Lakes surfaces can take a stronger one.
Gilbert's newer pools can still get algae blooms if the chemistry drifts, and once the spores work into the plaster, chemical treatment alone will not stop them from returning. The acid wash kills the spores at the surface level so the bloom cannot reestablish from the plaster. This is what breaks the cycle of green coming back every few weeks after shocking.
Before we apply any acid, we inspect the plaster for cracks, delamination, and thin spots. Newer Gilbert finishes are smoother and have more plaster to work with, but the older surfaces in Val Vista Lakes and Morrison Ranch need a closer look because they may have been washed before. We measure the condition honestly and tell you if the surface is too thin to safely wash.
The calcium ring on the tile builds fast on Gilbert pools because the hard water evaporates and leaves the mineral behind. While the pool is drained for the wash, we clean that ring off the tile so the waterline looks fresh. The tile is only practical to reach with the water down, so we fold it into every acid wash.
Once the surface is clean, we neutralize the acid with soda ash and rinse the entire pool thoroughly so no active residue stays in the plaster. We check the surface pH before starting the refill, because leftover acid keeps eating away at the finish after the pool is filled. We do not skip this step.
Many Gilbert pools run salt systems, so after the refill we set up the chemistry for a salt pool specifically. We balance the pH, alkalinity, calcium, and stabilizer, and we bring the salt level up so the cell can produce chlorine again. A freshly washed salt pool needs the full setup, not just a chlorine add, and we handle it all.
We use professional-grade muriatic acid, diluted to the strength that fits your plaster. Gilbert's newer finishes in Power Ranch, Seville, and Cooley Station need a gentler mix because the staining is shallow and the plaster is still fresh, while the older surfaces in Val Vista Lakes and Morrison Ranch can take a stronger one. We mix each batch on site based on what we see when the pool is drained.
For the refill and rebalance, we use chlorine, pH adjusters, alkalinity increaser, calcium hardness adjuster, and cyanuric acid stabilizer from suppliers like Hasa, BioGuard, and Leslie. For the many salt pools in Gilbert, we also bring the salt to get the system running again. Gilbert fill water runs hard, so the setup includes pulling the pH down and managing the calcium so the fresh surface does not scale again right away.
Every Gilbert acid wash follows the same sequence, with the acid strength matched to your finish, so the surface gets restored safely and the fresh water is balanced before you swim.
We pump the pool down and walk the empty shell to read the plaster. We look for cracks, thin spots, and delamination, and we identify where the scale and dust film are deepest. The acid strength is planned from the finish condition, with a lighter mix for newer Gilbert plaster and a stronger one for older surfaces.
We apply the acid solution in sections, scrub the walls and floor to lift the scale and film, and clean the tile line while the water is down. Once the surface is clean, we neutralize the acid with soda ash and rinse the whole pool thoroughly so no active acid remains in the plaster.
We refill the pool, test the fresh water, and build the chemistry from scratch. For salt pools, we bring the salt level up so the cell can produce chlorine again. We pull the pH down, set the alkalinity and stabilizer, and hand the pool back bright, clean, and ready to swim.
If you notice any of these, it is time to call us for a professional pool acid wash in Gilbert.
Every Gilbert acid wash covers draining the pool, inspecting the plaster, applying the acid solution, scrubbing the surface, cleaning the tile line, neutralizing and rinsing, refilling, and building the fresh water chemistry from scratch. For salt pools, we also set the salt level. We follow the same sequence every time so nothing gets missed.
An acid wash removes a thin layer of plaster, so we do not recommend it every year. The newer finishes in Power Ranch and Seville may not need one as soon, while the older surfaces in Val Vista Lakes might.
