Dry Blasting Process
how does it work?
With a compressed air setup similar to sandblasting, we use a dry mineral blasting material/media that is both water soluble and landscape safe to remove calcium scaling and mineral deposits from pool tiles and Pebble Tec, as well as a number of other exterior surfaces, without damaging the tile or grout. Comparable to Epsom salt, our blasting media is pH neutral (which doesn’t affect pool water chemical levels) and is safe to swim in immediately after application, so there is little to no downtime once the cleaning is complete.
All our blasting media is natural, silica and toxic-metal free, as well as non-hazardous and non-toxic.
Being kind to the environment is something that is very important to us here at Pegasus, so we've rejected the traditional calcium removal methods using harmful acids and cleaning chemicals, instead opting for an all natural and foliage-safe material with NO harmful residues or byproducts, protecting the health of your pool and landscaping, but most importantly the health of your friends and family that'll be enjoying your newly revived pool tile.
Here's a quick rundown:
Step 1. Shut off pool filtration system and drain water levels roughly 1 foot to reveal cleaning surface.
Step 2. From inside the pool, we use compressed air and blasting media to 'blast' away calcium and scaling.
Step 3. We then brush and wipe down tile to reveal revived and scaling-free tile. Yay!
Step 4. Begin water refill--once full, you (or your pool service) can turn all your systems back on and you're good to go!
but why should you remove that (unsightly) buildup?
Calcium scale and mineral deposits occur for a number of reasons, most commonly being an imbalance of chemicals, pH and alkalinity levels, as well as high concentrations of calcium and minerals in the water (hard water). These factors, combined with Georgia’s ever-changing temperatures and the inevitable increase in pool water evaporation during the summer months, cause the deposits to accumulate along waterlines on tiles, waterfall spillways, and on surrounding decorative rocks and stones.
Unfortunately, once calcium scaling has begun to buildup it can actually worsen the problem due to its own water solubility, constantly dissolving into the pool and then redepositing when allowed to evaporate. Besides its less-than-attractive appearance, these deposits can begin to accumulate within and cause unnecessary strain on pool filtration systems.
The longer calcium scaling is allowed to accumulate, the harder it is to remove due to repeated hardening cycles, which can cause irreversible damage to underlying tile and grout, leaving it stained, eroded, and eventually needing to be replaced.
While stained grout may not seem like much, if left untended it will become ingrained in the grout, eventually compromising your pool wall and tile settings by allowing water to make its way behind it, causing irreversible damage and tile loss.
