# Polymer Sealer

A polymer sealer is a protective coating applied to a cleaned and dried surface — glass, concrete, wood, metal, brick — that forms a long-molecule chain on the surface to repel water, dirt, and staining. In window cleaning, glass-specific polymer sealers (often silicon-dioxide based, sometimes called "glass coats" or "hydrophobic treatments") cause rain to bead and sheet off, which keeps windows cleaner 2-3x longer between professional cleanings. On concrete, acrylic or urethane sealers protect against oil, rust, and de-icing salt.

## In depth

The key to polymer sealer performance is preparation. A thorough clean — soft wash for biologics, acid wash for minerals, DI-water rinse for glass — is non-negotiable before sealing, because any contaminant trapped under the polymer becomes permanent. Our Quarterly Protective Coating Program for windows applies a professional glass polymer after every cleaning, which dramatically extends the time between appointments and delivers a measurably better look in the interim. Sealing is a low-effort, high-ROI add-on that pays for itself in reduced cleaning frequency.

## How this shows up on our jobs

Our exclusive Quarterly Protective Coating Program applies a glass polymer sealer after every window cleaning in Madison, which keeps glass cleaner up to 3x longer between visits.

[Anti-Slip TreatmentAnti-slip treatment is a chemical process — sometimes followed by a mechanical treatment — that increases the coefficient of friction on hard-surface flooring to reduce slip-and-fall risk when the surface is wet. The most common chemistry for stone, porcelain tile, and concrete is a mild hydrofluoric-acid-based etchant that micro-pits the surface invisibly, creating thousands of tiny suction cups that grip wet shoe soles. On glazed tile and quartz, polymer-bonded non-slip coatings add a textured clear layer that does the same job without etching.](/glossary/anti-slip-treatment)[Damp ProofingDamp proofing is the application of a moisture-resistant coating or membrane to a masonry surface — most commonly foundation walls, brick veneer, and chimneys — to slow water absorption and reduce efflorescence, spalling, and interior moisture problems. It is less robust than true waterproofing (which forms a continuous, pressure-rated barrier) but more cost-effective and better-matched to surfaces that need to breathe.](/glossary/damp-proofing)[OxidationOxidation is the chemical reaction between a surface and oxygen (plus UV light, moisture, and time) that produces a chalky, faded, or dulled appearance. On vinyl siding, oxidation shows up as a powdery white residue that rubs off on your hand. On fiberglass doors and garage doors, it is a milky film that makes the surface look faded. On aluminum gutters, it appears as a crusty, chalk-like coating called "tiger striping" when rain streaks it. On painted metal, oxidation is the precursor to true rust.](/glossary/oxidation)[Hard Water StainA hard water stain is the crystalline mineral deposit that forms on glass, metal, and stone when water high in dissolved calcium, magnesium, iron, or silica evaporates and leaves its dissolved minerals behind. The stain starts as a cosmetic film that rinses off easily; over weeks or months, it bonds chemically to the surface and etches into it, becoming progressively harder to remove. On glass, severe hard-water staining is technically etching — the minerals have chemically fused into the silicate surface and cannot be washed off without specialty chemistry or mechanical polishing.](/glossary/hard-water-stain)
