GlassProtect · by JUMBOGUARD
Glass & balustrades, sealed.
Cloudy, spotted glass that won't come clean no matter how hard you scrub? On pool fencing, balustrades and shower glass, hard water and salt slowly etch the surface, and once it's etched, scrubbing can't bring it back. GlassProtect is a 3× more durable coating that protects glass against permanent etching. Water sheets and beads off with far less dwell, so fewer minerals are left behind, and what does land does not bond: it wipes away with a squeegee instead of etching in.
The problem
What hard water does to glass.
Glass looks tough, but it's porous at a microscopic level. Minerals and salt work into the surface, and once glass is etched, it can't be cleaned back.
Hard water
Mineral-laden water dries and deposits, which can permanently etch glass.
Salt air
Coastal spray builds up on pool fencing and balustrades.
Oily soap scum
Soap reacts with hard water into a greasy film: the real reason glass looks cloudy, and what water-only coatings can't stop.
Scrubbing wear
Repeated hard scrubbing to shift deposits wears at the glass.
Step one
First, we prepare it properly.
A professional clean removes existing mineral film, salt and grime from the glass, so the coating bonds to a clean surface. The clean is included. It's preparation, not a separate service.
Step two
Then GlassProtect changes how it behaves.
- Protects against permanent etching. GlassProtect resists and delays the hard-water etching that bonds to and slowly eats untreated glass, by keeping mineral water from dwelling long enough to attack.
- Repels oily soap scum. GlassProtect is genuinely oil-repellent (an initial oil contact angle around 84°), so the greasy film hard water leaves, the real reason glass clouds, can no longer grip. Cleaning goes from scrubbing and chemicals to a single wipe.
- Spots wipe off, they don't etch in. Water sheets and beads off with far less dwell, so fewer minerals are left behind, and the ones that do land sit loosely on the surface instead of bonding. A quick wipe or squeegee clears them, where bare glass would need a razor blade.
- 3× more durable. GlassProtect is tested to be three times more durable, still beading after 3,000 scrub cycles.
- Keeps glass clearer for longer. Less mineral build-up between cleans, and what does build up clears in one wipe, not a razor blade and a bottle of acid.
See it work
Thrown at coated glass, and it just runs off.
Real test footage: GlassProtect on a pool-side glass panel. Water beads and sheets off with far less dwell, so far less is left to dry on, and what does land wipes away instead of etching in.
The proof
Tested 3× more durable.
Cream cleanser and a scrub pad is what actually wears a glass coating out. In comparable abrasion testing, GlassProtect held its water repellency about three times longer, still beading at 3,000 cycles, where the leading brand's test had already ended at 1,000.

The technology
Sealed with GlassProtect.
A professional-grade glass coating that bonds to the surface and protects it against permanent etching, tested 3× more durable. Applied by certified applicators to a JUMBOGUARD standard, and registered under a JUMBOGUARD guarantee: 10 years on new glass, 5 years on existing glass.

Questions, answered
Straight about spotting.
Does sealed glass still need any upkeep?
The hard part is done. GlassProtect turns keeping your glass clear from a job with a razor blade and a bottle of acid into a quick wipe or squeegee, because minerals and soap scum can no longer bond to the surface. Constant hard, bore or reticulation water with no upkeep can still leave spots, on any glass on earth, but on a coated screen those spots wipe away, where on bare glass they bond on and etch in for good. You are not buying glass that never needs a wipe. You are buying glass where a wipe is all it ever takes.
Will sealing stop my glass spotting?
Not stop, far less. On bare glass, hard water scale bonds on and eventually etches the glass for good. On coated glass, water sheets and beads off with far less dwell, so fewer minerals are left behind, and what does land does not bond. Spots sit loosely on the surface instead of keying in, so a quick wipe or squeegee clears them, where bare glass would need a razor blade.
What does GlassProtect do about etching?
Glass is the one surface where protection against etching is real. GlassProtect resists and delays the hard-water etching that bonds to and slowly eats untreated glass, by keeping mineral water from dwelling long enough to attack. It does not stop physical scratching or every chemical, but it holds off the mineral etching that permanently ruins bare glass.
We're on bore or reticulation water. Does GlassProtect still help?
Yes, and it is exactly where it earns its keep. Hard water still carries minerals, but on a coated surface they rinse and wipe away before they can bond and etch in. Bare glass under constant bore or reticulation water is where you see permanent, etched-in staining. A coated screen keeps clearer for longer and clears in one wipe, not a razor blade and a bottle of acid.
