If your Montgomery pool has lost its shine or the plaster looks rough and stained, you're probably wondering whether bead blasting or acid washing is the right move. Both methods clean and restore pool surfaces, but they work differently and suit different situations. The choice depends on what's actually wrong with your pool, how much damage there is, and what your budget can handle. I'll walk you through how each one works so you can make an informed decision before calling someone out to your house.
What Bead Blasting Does
Bead blasting uses compressed air to shoot tiny glass beads at your pool's plaster surface. Think of it like a very controlled sandblaster, except the beads are gentler than sand. The beads knock off algae, calcium deposits, and surface stains without eating into the plaster itself. It's a mechanical process, not a chemical one.
The real advantage here is control. A skilled operator can target problem areas without damaging healthy plaster. If you have a few stubborn stains or light algae growth, bead blasting gets them off quickly. It also works well if you want to freshen up the surface without the harshness of chemicals. In Montgomery's heat and humidity, algae can creep back fast, and bead blasting is a solid preventive tool. The downside is cost. It's more expensive per hour than acid washing, and it takes longer for larger pools.
What Acid Washing Actually Does
Acid washing is a chemical process. A diluted acid solution gets applied to the plaster, and it dissolves the top layer of the surface along with stains, calcium, and algae. It's aggressive and fast. For heavily stained or discolored pools, acid washing cuts through problems that bead blasting might not touch.
The catch is that acid washing removes plaster. It's not just cleaning. If your plaster is already thin or you do it too often, you're shortening its life. Acid washing also requires serious safety precautions. You need proper ventilation, protective gear, and someone who knows how to handle acid without damaging the pool structure or surrounding areas. Once the acid goes down, the damage is done if something goes wrong. In Montgomery's humid climate, the fumes can be intense, and you'll want the job done by someone experienced.
Stains That Matter
Not all stains respond the same way to both methods. Metal stains from iron or copper in your water respond better to acid washing. If you have a green or brown tint that won't come off with brushing and chemicals, acid is likely your answer. Organic stains from leaves or algae often respond well to bead blasting, especially if they're not deep.
If you're not sure what you're dealing with, a pool professional can take a closer look. Sometimes what looks like a permanent stain is just algae that needs the right treatment first. That's worth figuring out before you commit to either process.
Plaster Age and Condition
How old your plaster is matters. If your pool is five years old or newer, the plaster is probably thick enough to handle acid washing without major risk. If it's ten years or older, bead blasting is the safer bet. Older plaster is thinner, and acid washing can expose the substrate underneath or create weak spots.
Bead blasting also makes sense if you've already had acid washing done recently. Doing it twice in a few years is rough on the plaster. Spacing them out with bead blasting in between keeps your pool looking good without accelerating wear.
Cost and Timing
Bead blasting typically runs higher per job because it takes longer. Acid washing is faster and cheaper upfront. If you're on a tight budget, acid washing gets the job done. But if you're thinking long-term and your plaster is in decent shape, bead blasting costs less over time because it doesn't shorten your plaster's lifespan.
Timing matters too. Both jobs are easier when the weather cooperates. In Montgomery summers, early morning or late afternoon is better for acid washing to avoid the worst of the heat and fumes. Bead blasting can happen anytime, but you'll want to avoid windy days when the beads scatter.
When to Call a Professional
This isn't a DIY situation. Acid washing requires licensing and training in many areas, and the liability isn't worth handling it yourself. Bead blasting requires specialized equipment and skill to avoid damaging plaster or equipment. Either way, you need someone who's done this work and knows Montgomery pools specifically.
