Iron from hill-country well water and tannins from cedar and oak trees leave stubborn stains on Liberty Hill plaster. Our controlled acid wash lifts that discoloration and restores a clean, bright surface.
A focused pool acid wash visit covers the specific problems that show up on Liberty Hill pools. Here is what we handle on every repair.
Well water in parts of Liberty Hill carries iron and minerals that deposit as brown and rust-colored stains on the plaster, and cedar and oak debris adds tannin discoloration on top. We determine whether the staining is organic, metallic, or scale before we commit to an acid wash, because each type responds differently. A correct read on the stain source is what prevents a wash that does nothing.
We lower the water to a working depth and shield the tile, the fittings, and the surrounding deck so acid contacts only the plaster. The rural properties around Stonewall Ranch and Butler Ranch often have equipment pads exposed to the elements, so we take extra care covering the pump and the heater. Protecting everything outside the plaster is what keeps a wash from creating a repair.
We brush a measured muriatic acid solution across the plaster in controlled sections, working from the deep end up so the strength stays even. Liberty Hill pools near the South San Gabriel River often have heavier iron staining at the waterline that needs a focused second pass. Controlled, even application is what lifts the stains without over-thinning the finish.
Once the stains lift, we neutralize the acid with soda ash and rinse the surface until the runoff tests clean. Liberty Hill well water can reintroduce iron on refill, so a thorough neutralize and a pre-treatment of the fill water is what keeps the stains from coming right back. We test before we start filling.
We refill the pool and balance the chlorine, pH, alkalinity, and iron sequestrant as the water rises. Pools on well water in Liberty Hill often need a metal sequestrant added during the fill to hold the iron in solution, or the fresh plaster stains again within days. Treating the fill water as we go is what locks in the brightness.
We leave you a written summary of the plaster condition, including any areas where iron staining has been recurring or where the surface is getting thin. That record helps you track whether a sequestrant routine or a resurface is in your future. Straightforward reporting is what helps you plan ahead with real information.
We use professional-grade muriatic acid mixed to the stain type we identified, whether that is iron deposits, tannin discoloration, or scale. The older plaster pools near Downtown Liberty Hill often need a gentler solution, while the newer finishes in Santa Rita Ranch can take a standard mix. After the wash we neutralize with soda ash and rinse until the surface is clean. Matching the acid to the specific stain is what makes the wash effective instead of generic.
On refill we rebalance with chlorine, pH adjusters, alkalinity increaser, calcium, and a metal sequestrant from brands we trust like BioGuard and ProTeam. Liberty Hill well and hill-country municipal water tends to carry iron and minerals that can stain fresh plaster within hours if it is not treated, so we add sequestrant and adjust the chemistry as the pool fills. Getting ahead of the iron during the fill is what holds the bright finish. For the full scope of our pool acid wash work across the area, see our Pool Acid Wash overview page.
We diagnose the real cause, send a clear written quote, and verify the fix before we leave your Liberty Hill backyard.
We pump the water out and examine the plaster to confirm the stains will respond to acid and that the surface has enough life left for a wash.
Before any acid touches the plaster, we hand you a plain-language written quote covering the wash, the neutralization, and the refill treatment.
We apply the acid wash in sections, neutralize and rinse the surface, refill the pool, and treat the fill water so the finish comes back bright and the iron stays in solution.
Liberty Hill pools fight a double threat from iron-rich well water and tannin-heavy cedar and oak debris, and that combination leaves stains that brushing and chemicals alone will not remove. A few clear signs tell you the plaster would benefit from an acid wash.
We inspect the surface first to confirm the discoloration is stain and not etching, because acid makes an etched finish worse.
An acid wash makes sense when the plaster is healthy but stained from iron and tannins, because it lifts the discoloration at a fraction of the cost and time of a full resurface. If the finish is cracked, etched, or too thin, a wash will not help and can make things worse, so we tell you straight when a resurface is the better path. Many older Liberty Hill pools near Downtown fall in the middle, and we help you weigh the real tradeoff.
We hand you a free written quote after inspecting your pool, no pressure, so you can weigh a wash against a resurface with the real facts in front of you. When a wash will handle it, we tell you, and when the plaster is too far gone, we tell you that too. The aim is the right fix for your surface, not the larger job.

Stains and plaster wear in Liberty Hill trace back to conditions that are specific to these neighborhoods. We plan the acid wash around what is actually causing the dullness.
The open hill-country lots in River Ranch and Bridle Gate catch steady breezes that blow tannin-rich leaves and organic material into the water, leaving brown and greenish stains on the plaster over time. Brushing alone will not lift those organic stains, and an acid wash is what removes the discolored layer. We adjust the acid strength to the stain type so the surface brightens without being etched too deep. Knowing the organic stain source common here shapes how we plan the wash.
Liberty Hill draws hill-country well and municipal water that tends to carry minerals, which leave scale and metal stains on the plaster, especially on the older pools near Downtown where the surface has aged. An acid wash lifts those mineral deposits, but we also adjust the fill water chemistry on refill so the stains do not return right away. Testing the fill water as the pool refills is what holds the bright finish. That balance step matters more here than on pools with softer fill water.
