TotalBoat Epoxy Primer Thinner 200 Solvent, 32 Fl Oz (Pack of 1) — Improves Flow & Spray Atomization for Marine Epoxy Primers

TotalBoat Epoxy Primer Thinner 200 is a purpose-built marine solvent that improves flow and extendability for TotalBoat epoxy barrier and 2-part primer systems.

Designed for boatbuilders, repair shops, and DIY boat owners, this quart-sized thinner is formulated to work specifically with TotalBoat TotalProtect Epoxy Barrier Coat, Aluminum Boat Barrier Coat, and TotalBoat 2-Part Epoxy Primers (Surfacing, High-Build, and Clear). It helps achieve smoother brush, roller, and spray application, serves as an effective solvent wipe for certain rubberized surfaces, and cleans tools after use. Manufactured in the USA, this product is intended for use only with the TotalBoat systems listed.

How does this thinner improve epoxy primer application?

Thinner 200 reduces viscosity so primers level better and spray nozzles atomize more consistently. That makes it easier to produce an even wet film without overworking the epoxy, which helps reduce brush or roller marks and improves substrate coverage.

• Enhances flow and leveling for brush, roller, or spray
• Reduces orange peel when spraying high-build or surfacing primers
• Helps maintain working pot life and better film formation

Can I use this solvent for surface preparation and cleanup?

Yes — Thinner 200 doubles as a cleaning solvent for brushes, rollers, and spray equipment after applying compatible TotalBoat primers. It is also recommended as a solvent wipe on rubberized inflatable materials before applying TotalBoat Inflatable Boat Bottom Paint to improve adhesion.

• Wipes rubberized surfaces to remove contaminants before painting
• Safely cleans uncured epoxy residue from tools and equipment
• Use only with the specified TotalBoat primer systems to avoid compatibility issues

What are the practical mixing and application tips for best results?

Start with small additions and follow TotalBoat product technical data for recommended thinning percentages. For spray, thin enough to achieve smooth atomization without breaking the epoxy chemistry; for brushing or rolling, thin only as needed to improve flow and reduce brush marks.

• Add thinner incrementally and mix thoroughly between additions
• Observe pot life and environmental conditions—temperature and humidity affect performance
• Always follow safety guidelines and use appropriate ventilation and PPE

Is this product safe to use on all surfaces and with other brands?

Thinner 200 is formulated specifically for TotalBoat primer systems and for use as a prep wipe on certain inflatable rubberized materials. It is not recommended for arbitrary mixing with unrelated brands or for substrates not approved by TotalBoat because compatibility and performance are not guaranteed.

• Intended for use only with specified TotalBoat primers and coatings
• Not recommended for unknown or untested coating systems
• Test small areas when unsure and consult technical bulletins for guidance

Who is this for? TotalBoat Epoxy Primer Thinner 200 is aimed at professional marine painters, boat owners who tackle their own maintenance, and restoration shops that use TotalBoat TotalProtect, Aluminum Boat Barrier Coat, or 2-part epoxy primers. If you need a compatible solvent to improve application, prepare inflatable surfaces before bottom paint, or clean tools after epoxy work—and you use the specified TotalBoat products—this quart offers a convenient, USA-made solution.
