SharkThane Plus purchase now includes a
FREE bottle of
ScenTralock™.
What ScenTralock does: Helps neutralize and suppress odor while acting as a reactive additive that supports internal bonding and coupling inside the coating. The result is a tighter, more chemically resistant finish.
1. Why Professionals Reach for SharkThane Plus
The “Bulletproof” Advantage
SharkThane Plus is built for jobs where failure is not an option. It combines UV absorbers, anti-graffiti protection, CRU durability, and high-build versatility in one premium system.
High Build • High Clarity
This high-viscosity clear is designed to lay material where it belongs — on the surface — instead of losing film build out the exhaust like thinner clears. Ideal when you need maximum clarity, full coverage, and a richer protective film.
2. Anti-Graffiti Revenue Opportunity
What You Sell
- Premium add-on revenue through anti-graffiti protection
- A clearcoat protection story customers understand instantly
- Protection for tubs, tile, counters, concrete, and more
- An easy explanation: “graffiti doesn’t penetrate — it wipes off”
Pro move: Charge more because you are selling protection — not just paint.

High-Build Countertop Clarity
Why High Viscosity Matters

- Higher build increases impact resistance
Pro note: Thin clears may look wet, but they often leave you short on build and protection.

6. Mixing Instructions
Exact Mix Ratio
- 4 parts Part A (Resin)
- 1 part Part B (Catalyst)
- Mix thoroughly until fully uniform before reducing.
Rule: Measure every batch — no eyeballing.
Typical Tub Coverage
- Minimum for a standard tub:
- 12 oz Part A (Resin)
- 3 oz Part B (Catalyst)
- Increase total volume for larger tubs or heavier film builds.
Reducer Selection & Equipment Considerations
Reducer amount depends on temperature, air movement, and spray equipment.
- 2–3 stage turbines typically require more reducer.
- 5–6 stage turbines require less due to better atomization and higher air volume.
- Always spray a test panel when conditions or equipment change.
7. Cure, Return-to-Service, and Fast-Turn Jobs
Cure & Return-to-Service
- Caulk window: typically 20–30 minutes
- Typical return-to-service: 16–24 hours
- Need it faster? Use MAKO Cold Cure Accelerator to cut return-to-service to 8–12 hours
Pro reality: dry to touch is not back in service. Let the urethane crosslink.
MAKO Cold Cure Accelerator
For hotels, occupied units, cold-weather work, or fast-turn schedules, MAKO Cold Cure Accelerator can reduce typical return-to-service from 16–24 hours down to 8–12 hours when used correctly.
Mix guidance: 2 oz per mixed quart
Pot life warning: MAKO shortens pot life from about 4–5 hours to about 2–3 hours.
8. Add-Ons Professionals Use on Real Jobs
These two additions make jobs cleaner, faster, and more professional when timeline and finish quality matter.
MAKO Cold Cure Accelerator
Cuts return-to-service from 16–24 hours down to 8–12 hours on jobs where speed matters.

9. Full Melt Down™ Tub Technique
Make Your Customers & Competition MELT
When you use the Full Melt Down™ Tub Technique, the finish goes from good to jaw-dropping.
The Wet Glass Full Tub Melt Down Move
This is how pros get that basecoat-clearcoat look on tubs. The surface reflows, stop-start marks disappear, and the finish reads like sprayed glass. Translation: customers stare and competitors get quiet.
The pro move that separates good from jaw-dropping.
Do This Before Your Final Gloss Coat
Stop. Do not spray your final gloss coat yet. Follow these steps to reflow the surface for a deep, wet-glass finish.
- Add 1–2 oz of Melt Down™ to your existing mixed material in the spray cup.
- Mix thoroughly.
- Turn your fluid down to prevent runs and sags because you just increased solvent content.
- Spray one thin, even, wet gloss coat over the entire surface.
What This Final Coat Does
- Reflows the entire surface
- Eliminates dry spray and stop-start marks
- Softens microscopic texture
- Amplifies DOI for wet-glass gloss
Why Pros Use It
After your build and hide coats with SharkThane Plus, this step lays down a finish that looks like base coat / clear coat gloss — the kind that wins hotels, GCs, and high-end clients.
10. Technical Notes & Pro Caveats
Highlighted Caveat
Apply your first passes light. Heavy, wet coats of hot solvent can lift sensitive primers or existing coatings. When in doubt, dust it on, give it a short flash, then build.
