MicroGlass Pool Coating in California's Central Valley
Hard water and intense heat wear down pool surfaces faster in the Central Valley than almost anywhere else in California. MicroGlass is a protective coating that seals the surface, reduces buildup, and extends the life of your pool finish.
What Is MicroGlass and How Does It Protect Your Pool?
MicroGlass is a specialized pool surface coating that creates a smooth, low-porosity protective layer over plaster, pebble, or quartz finishes. Unlike resurfacing, which replaces the underlying surface material, MicroGlass is applied as a top coat — bonding to the existing or newly finished surface to reduce the rate at which algae, calcium, and mineral deposits adhere going forward.
Resists Calcium Buildup
Sealed, low-porosity surface slows the reattachment of mineral scale — a real win in Central Valley hard water.
Fights Algae Attachment
The smooth coating makes it harder for algae to grip the surface, keeping your pool cleaner between treatments.
Brighter Water Appearance
The reflective finish enhances water clarity and color — pools often look bluer and cleaner overall.
Smoother Underfoot
A noticeably smoother texture on plaster and pebble surfaces — easier on swimmers' feet without losing grip.
The result is a surface that stays cleaner between services, reflects light more evenly for a brighter water appearance, and is noticeably smoother underfoot. In Central Valley, where high mineral content in the water means calcium buildup is an ongoing maintenance challenge, MicroGlass provides a practical layer of protection that makes a real difference.
Signs MicroGlass Is the Right Upgrade for Your Pool
MicroGlass is a smart investment for pools experiencing ongoing maintenance challenges that routine cleaning can’t solve on its own.
Common Signs Include
- Recurring calcium or mineral deposits that return quickly after cleaning
- Rough-feeling plaster or pebble surfaces that are hard on feet
- A dull or cloudy water appearance despite proper chemical balance
Additional Warning Signs
- Algae that reattaches persistently after treatment and brushing
- Surfaces that stain easily or absorb discoloration over time
- Pools that were recently resurfaced or acid washed and are due for protection
If any of these describe your pool, MicroGlass is worth considering as part of your next surface service.
Complete MicroGlass Application Service
MicroGlass application by Cal West includes:
- Surface preparation, the pool must be freshly acid washed or newly resurfaced before coating

What Our Customers Are Saying
Our reputation is built on satisfied homeowners and successful pool projects throughout the Central Valley.
Cynthia, Juan and their entire crew was incredible to work with for our new pool! They were patient with us, and treated our pool build as though they would for themselves. They paid attention to every detail and the execution was flawless! I feel so grateful to have had them work on our pool! We’re looking forward to decades of fun to come.
We have a 34 year old indoor pool that needed resurfaced. Cal -west came out and gave us a fair bid. They were able to handle the complexity of dealing with the indoor pool very well. They showed up each day they said they would and did a great job. They cleaned up well and it only took about a week to start enjoying the pool again.
I had Cal-West replaster my peeling pool. Juan and Cynthia are very professional and timely. Their crews were on time every time. I also agree 100% with another review that the crew left the job site very clean after each phase of their work. It was like they were never there. They are very reasonably price compared to other quotes I had received. I highly recommend Cal-West and will use them again.
Our Proven MicroGlass Process
MicroGlass application follows a precise process to ensure the coating bonds properly and delivers its full protective performance.
Assessment
We confirm the surface is a candidate for MicroGlass (newly resurfaced or freshly acid washed).
Surface Prep
If part of the Revival Package, the acid wash and neutralization are completed first. If post-resurfacing, the surface is confirmed cured and ready.
MicroGlass Application
The coating is applied evenly across the entire pool surface.
Cure Period
The coating is given appropriate cure time before the pool is refilled.
Refill & Water Chemistry
The pool is refilled and water chemistry is balanced to protect the coating from day one.
Final Inspection
We confirm finish quality and application coverage before closing out the project.
Common Questions About MicroGlass
What is MicroGlass made of?
MicroGlass is a glass-based protective coating formulated specifically for pool surfaces. It creates a smooth, sealed layer over plaster or pebble finishes that reduces porosity and the adhesion of calcium, mineral scale, and algae.
Does MicroGlass replace resurfacing?
No. MicroGlass is a coating applied over an existing or new surface — it doesn’t repair or replace plaster. For pools with cracked, delaminating, or significantly worn plaster, resurfacing needs to happen first. MicroGlass is then applied afterward to protect the new finish.
How long does MicroGlass last?
Longevity varies based on water chemistry maintenance, usage, and local water conditions. With proper care, the coating is designed to remain effective for several years. In Central Valley’s hard water conditions, maintaining balanced chemistry is important for getting the most out of the coating.
Can MicroGlass be applied to any pool surface?
It works best on plaster and pebble finishes. The surface needs to be properly cleaned or freshly applied before the coating goes on. We assess each pool before recommending MicroGlass to make sure it’s a good fit for the specific surface condition.
Is MicroGlass slippery?
No. The coating creates a smoother surface, but it’s formulated for pool use and doesn’t create a slip hazard. Rough-textured pebble finishes retain enough texture through the coating to remain safe for swimmers.
Does MicroGlass change the water color?
The coating creates a brighter, more reflective surface, which typically enhances water clarity and color — pools often look bluer and the water appears cleaner overall. It doesn’t change the fundamental color of your pool finish.
