Description
BULL SHARK ADHESION PROMOTER
Tie Coat • Adhesion Layer • Flex Agent • Fisheye Defense
A premium micro-film adhesion layer engineered to bond coatings to tough substrates — , metal, ABS plastic, fiberglass, cultured marble, Formica, and composites. Built through a refinisher’s eyes for bathtub, tile, countertop, and industrial work.
What Bull Shark Does (In Plain English)
Think of Bull Shark like a high-tech, ultra-thin “two-way tape”. It lays down a bonded micro-film that gives your next coating something to grab, lock onto, and move with. It’s the bridge between “this surface doesn’t want paint” and “this coating is here to stay.”
1) Tie Coat Primer
When you can’t strip an existing layer, mist Bull Shark over it to secure and seal the surface, creating a fresh film that your next product can bond to.
2) Adhesion Promoter
Built for “difficult” surfaces: glass, plastics, fiberglass, cultured marble, Formica and composites. The goal: a reliable adhesion foundation before your coating system goes on.
3) Flex Agent (Substitution Method)
To increase flexibility, substitute 1 part of your reducer mix with Bull Shark. Example: if your mix calls for 3 oz reducer, use 2 oz reducer + 1 oz Bull Shark.
4) Fish Eye / Blush Defense
Bull Shark leaves a bonded micro-film across the surface, helping block minor contamination from becoming fish eyes, blushing, and repellency. It’s a bridge layer that makes your system more forgiving.
Professional Surface Prep & Application
- Clean thoroughly. Remove oils, waxes, silicones, polishes, and residues (the invisible killers).
- Create a dull surface. Light scuff where appropriate for mechanical bite — remove dust completely.
- Mask adjacent areas. Prevent overspray and keep your finish professional.
- Apply Bull Shark as a thin mist. This is a micro-film — do not apply heavy coats.
- Allow adequate flash. Let the film settle before topcoating for best bond and performance.
- Topcoat within your workflow window. Don’t drag the process out — keep the system moving.
Flex Agent Mixing Chart (Universal Substitution)
Use this chart for SharkThane systems, High Gloss Epoxy, and Liquid Porcelain Enamel whenever you’re using Bull Shark as a flex agent. Replace 1/3 of your reducer blend with Bull Shark.
| Total Reducer Mix | Reducer | Bull Shark |
|---|---|---|
| 3 oz | 2 oz | 1 oz |
| 6 oz | 4 oz | 2 oz |
| 9 oz | 6 oz | 3 oz |
| 12 oz | 8 oz | 4 oz |
Mixing Tips (Don’t Skip)
- Measure accurately. Guessing kills consistency.
- Mix thoroughly. Even distribution matters.
- Use clean equipment. Residue can interfere with bonding.
- Test first. Especially on unknown coatings.
- Respect flash time. Let the film settle before topcoat.
Application Tips (Field-Proof)
- Thin, even mist. Heavy coats reduce performance.
- Ventilation matters. Helps flash and keeps you safer.
- Control the environment. Temp/humidity affects behavior.
- Avoid contaminants. Dust and lint love wet films.
- Plan your workflow. Don’t delay between steps.
Safety Essentials
- Wear PPE: gloves, eye protection, and appropriate respirator/mask.
- Ventilate: especially indoors. Proper airflow improves results and safety.
- Avoid skin contact: wash immediately with soap/water if exposure occurs.
- Store properly: cool, dry, sealed, away from heat and sunlight.
- Dispose responsibly: follow local regulations for chemical waste.
