Koch Chemie HydroBoost: The Spray Topper That Refreshes Your Protection
Koch Chemie HydroBoost is the spray-on hydrophobic topper from the Koch Chemie The Finisher line, engineered to refresh and extend the water-beading behaviour of your existing wax, sealant or ceramic coating. Apply after a wash and your hydrophobic performance returns to peak levels in minutes, without the prep work or curing time of a full coating application.
Where wax and polymer sealants lose their hydrophobic punch after a few weeks, HydroBoost rebuilds that water-beading layer instantly. The German formulation uses silicon-based chemistry that bonds to your existing last-step protection rather than replacing it. Apply over a clean, wet surface as a drying aid, or over dry paint as a quick standalone topper. Every application leaves paint feeling slick and water sheeting like new.
Why Detailers Trust HydroBoost
Instant hydrophobic refresh: water beads and sheets like the day your coating was applied, within minutes of use.
Topper-compatible: bonds with wax, polymer sealant and ceramic coating without stripping the underlying layer.
Drying-aid friendly: spray onto a wet surface during drying for a one-pass refresh that also helps the towel glide.
Multi-surface safe: paint, glass, wheels, plastic trim and chrome all benefit from the same bottle.
Streak-free finish: wipe to a high-gloss with a clean microfiber towel, no haze or residue.
Made in Germany: formulated and bottled in Koch Chemie's own laboratories in Unna.
How to Use Koch Chemie HydroBoost
As a drying aid (wet application):
Wash and rinse the vehicle thoroughly with MagicShampoo or your preferred shampoo.
While the surface is still wet, mist HydroBoost onto a 2x2 ft section of paint, glass or trim.
Wipe with a plush microfiber drying towel using straight passes. The towel will glide more easily and pick up water at the same time.
Continue panel by panel until the vehicle is dry and the protection layer is refreshed.
As a standalone topper on dry paint:
Mist 2 to 3 sprays onto a clean section of paint.
Spread evenly with a clean microfiber applicator pad or towel.
Buff to a high gloss with a second clean microfiber towel using straight passes.
Repeat panel by panel.
Pro tip: apply HydroBoost over a clean ceramic coating every 4 to 6 weeks to keep the coating's water-beading at peak levels well beyond its natural maintenance cycle. Pair with TropicSnow pre-wash and MagicShampoo contact wash for a complete Koch Chemie The Finisher workflow.
Important: apply in the shade on a cool surface. Hot panels and direct sunlight cause the product to flash before you can wipe.
Durability: 4 to 6 weeks of refreshed hydrophobic performance per application
Application: wet (drying aid) or dry (standalone topper)
Coverage: a 500ml bottle treats 8 to 12 full vehicles as drying aid, 20 plus as standalone topper
Available size: 500ml
Made in: Germany, by Koch Chemie GmbH in Unna
Brand line: Koch Chemie The Finisher (premium consumer range)
Frequently Asked Questions
Is HydroBoost a replacement for a ceramic coating?
No. HydroBoost is a topper designed to refresh and extend the hydrophobic behaviour of an existing wax, sealant or ceramic coating. It is faster and easier to apply than a full coating but the durability is measured in weeks rather than years. The two products work together: ceramic coating for long-term protection, HydroBoost for ongoing maintenance refreshes.
Can I use HydroBoost on glass and wheels?
Yes. The same formula works on paint, glass, wheels, plastic trim and chrome. On glass it improves water repellency similar to a rain repellent. On wheels it adds a slick layer that makes the next brake-dust cleaning easier.
How often should I apply HydroBoost?
Every 4 to 6 weeks for a daily driver, or after every wash if you want maximum water beading. For a garage-kept weekend car, every 2 to 3 months keeps the hydrophobic refresh at peak levels.
Does HydroBoost strip my wax or sealant?
No. HydroBoost bonds to your existing last-step protection rather than replacing it. Use it over wax, polymer sealant or ceramic coating without concern about stripping the underlying layer.
Can I use HydroBoost in direct sunlight?
No. Apply in the shade on a cool surface. Hot panels and direct sunlight cause the product to flash off too quickly, leading to streaks and high spots.
Where is HydroBoost made?
Koch Chemie HydroBoost is formulated and bottled in Germany by Koch Chemie GmbH at their headquarters in Unna. The Rag Company Europe is an authorised dealer of the Koch Chemie The Finisher line for Europe.
