Where to Use MicroGlass

MicroGlass is a Pool Plaster Preservation
and Renewal System Unlike Any Other

Everyone loves the creative flexibility of gunite/concrete swimming pools, in large part because the plaster, quartz and pebble interiors are so stunningly beautiful. But the natural porosity of these interior finishes allow chemical reactions between the plaster and the pool water, which plays havoc with the water chemistry and pool maintenance. In many cases, these interactions will produce undesirable effects in the finish, such as etching, spalling, micro-cracking, color loss, calcium nodule growth, and cloudy water from new plaster dust.

For Use on:

All types of new or existing Pool & Spa plaster including marcite, quartz, pebble, and polished finishes


New Plaster

Builders & Plaster Contractors.

If you’re installing a new pool (or re-plastering an existing pool), MicroGlass is the perfect “final step” to:

  • Permanently protect the plaster finish.
  • Minimize / prevent micro-cracks.
  • Greatly simplify the startup process.
  • Protect against plaster-based pH and alkalinity swings.
  • Produce cleaner, clearer water more quickly, with less work.

It’s also non-toxic, environmentally friendly, and easy to apply by a pool professional

Upon application, MicroGlass interacts with and strengthens the fresh plaster, to immediately and permanently minimize the chemical reactions between the water and the cement material within the interior finish. The annoying “dusting” that typically occurs with a new plaster finish is virtually eliminated. And if staining occurs from water contaminants (iron etc.), it will be MUCH easier to remove, because the MicroGlass has no rough surfaces for the contaminants to adhere to.

Using incredibly small nanoparticles, the MicroGlass product will penetrate the tiny voids and capillaries in the pool plaster, and convert the Calcium Hydroxide into a glass-like silicate that strengthens, hardens and protects the plaster from chemical attack.

MicroGlass is recommended for ANY plaster, polished quartz, or pebble-based finish in a pool or spa.  If set accelerators containing calcium chloride were used, see these detailed instructions.

MicroGlass is an OUTSTANDING upgrade for any pool that is about to undergo an acid-wash process.

Your acid-wash will make the old finish beautiful again, while the MicroGlass will harden, protect and extend the life of that plaster, just like it does for new plaster.

NOTE: After any acid-wash, the finish must be properly neutralized with a sodium bicarbonate wash, followed by a pressure wash before applying MicroGlass. (Read the instructions carefully before applying MicroGlass.)

Existing Plaster

MicroGlass will also simplify your ongoing maintenance of the pool, as the plaster-related pH swings will be virtually eliminated. Most pool technicians report a reduction in overall chemical usage also.

When is MicroGlass NOT recommended for existing plaster?

If the pool plaster is seriously damaged, and clearly due for replacement, MicroGlass won’t fix that. However, if there is still some usable life in the plaster, the MicroGlass treatment will give you noticeably more life than the simple acid wash alone.

If Calcium Chloride Set accelerators were used in your new finish mix, see these instructions for how to properly apply MicroGlass.
