When you're looking at your pool and seeing algae stains, calcium buildup, or a waterline that's lost its shine, a bead blast or acid wash can make a real difference. Both methods strip away years of grime and mineral deposits that regular brushing and chemicals won't touch. But if you jump straight into either treatment without doing some prep work, you're wasting money and risking damage to your equipment and surrounding areas. A few days of honest work beforehand will make the process faster, safer, and actually effective.
Drain Your Pool Completely
Start by draining the pool. This isn't negotiable for either bead blasting or acid washing. You'll need to turn off the pump and filter system first, then use a submersible pump or your existing circulation system to empty the water. In Montgomery's heat, this can take a full day or more depending on your pool size. Make sure you're not draining into a neighbor's yard or creating erosion problems. Check with your local water authority about proper disposal, especially if you're using any algaecide or other chemicals in the water.
Once it's empty, let the pool sit for a few hours. This helps any remaining sediment settle to the bottom so you can see what you're actually working with.
Brush and Scrub the Interior
This step saves the professionals time and saves you money. Use a stiff pool brush to loosen up loose algae, dirt, and any flaking paint or plaster. Pay special attention to corners and steps where debris collects. Get into the deep end and work systematically. You don't need to get it spotless, but you should remove anything that's sitting loose on the surface.
For stubborn stains or buildup, a pumice stone works well on plaster surfaces. Just test it in an inconspicuous spot first to make sure it won't damage your finish. Rinse everything down with a hose as you go.
Clear and Protect Equipment and Surrounding Areas
Acid wash creates fumes and can damage anything it touches that's not pool plaster or tile. Walk around your pool deck and identify what needs protecting. Cover any landscaping, deck furniture, or grills with tarps or move them away from the pool area entirely. If you have any delicate plants close to the pool, this is the time to relocate them temporarily.
Check your pool equipment. If you have a heater, pump house, or any metal fixtures near the pool, make sure they're either shielded or far enough away that overspray won't reach them. Acid wash fumes can corrode metal quickly.
Check Your Plaster or Finish Condition
Before the pros arrive, take a close look at your pool's interior surface. If you have plaster, look for cracks, soft spots, or areas where the finish is peeling away. If the structural damage is significant, an acid wash might not be the best choice, and you should mention this to the service technician when you call. A bead blast is gentler and might be the better option if your plaster is already compromised.
Similarly, if you have tile, check the grout. If it's already failing or missing in spots, the high-pressure or chemical process could make it worse.
Shut Off Gas and Electricity
If your pool has a gas heater or any electrical equipment that runs the pump and filter, turn it all off before the service day. Leave it off until the technician confirms it's safe to restart. Acid fumes can damage electrical components, and you don't want anything running while the pool is being treated.
If you're not sure where your breaker is or how to safely shut things down, just ask the service company when you schedule. They're used to this question.
Plan for Refilling and Rebalancing
After the bead blast or acid wash, your pool will need to be refilled and the water chemistry will need to be completely rebalanced. This takes time. Schedule your service when you can leave the pool empty for at least 24 hours afterward. In Montgomery summers, refilling can take several hours depending on your water pressure and hose setup. Budget another day for the chemicals to stabilize before you use the pool.
Have your test kit ready or plan to take a water sample to a local pool supply store for analysis before you get in the water.
One Final Walk-Through
The day before service, do a final check. Make sure the pool is empty or drained to the right level, all loose debris is removed, equipment is covered or moved, and you've got a clear path for the service team to access the pool from their truck. In Montgomery, heat moves fast, so if you're doing this in summer, start early in the morning.
