Seajet Thinner U - Urethane
Seajet Thinner U is specially designed for thinning urethane-based paints and coatings. It improves the flow properties of the coatings and facilitates application, resulting in a smooth and even surface.
- Application : The recommended dilution rate varies depending on the product and application method. It is important to follow the specific instructions of each polyurethane product.
- Contents : Available in 1 liter containers.
- Storage and shelf life : Store in a cool, dry place. Shelf life up to 2 years in unopened original packaging.
- Cleaning : Ideal for cleaning tools after applying polyurethane paints to effectively remove residues.
Instructions for use : Stir the paint or coating thoroughly before use. Then add the recommended amount of Seajet Thinner U and mix well to achieve the desired application viscosity. After application, immediately clean the tools used with Seajet Thinner U to prevent the coating residue from drying.

FAQ
Visit our guides to learn more.
How many coats do I need?
The number of coats is product-specific. Many antifoulings are applied in two coats for a first application; Seajet 034 may require three coats for potential multi-season protection. Seajet 021 EKO and Seajet 2300 are applied in two coats. The Bioclean system consists of two coats of Tie Coat and two coats of Clear Coat. The current technical data sheet is always decisive.
Do I need to remove the old antifouling?
A firmly adhering, compatible existing coating can be cleaned, prepared and overcoated, depending on the product. Flaking, cracked or unknown layers must be removed back to a sound system. The compatibility table shows whether direct overcoating is possible or a barrier coat is required.
Do I need to use a primer?
Not always. A suitable primer system is required on bare substrates, for corrosion or osmosis protection, and between unknown or incompatible systems. Preparation according to the data sheet may be sufficient on a sound, compatible existing coating. Seajet 117 is used as an epoxy primer and barrier coat; Seajet 015 can be used as an adhesion or barrier coat. Function and coat number depend on the substrate and data sheet.
Why do you only sell Seajet coatings?
We focus on Seajet so that antifouling, primers, thinners and topcoats can be selected as clear, compatible systems. Technical data, compatibility information and specific coverage figures form the basis of the configurator and quantity calculations. The individual product must still be suitable for the hull material, cruising area and use.
How often should I renew antifouling?
Inspect the coating when the boat is hauled out and before every season. Renewal depends on the product, film thickness, time afloat, use, cruising area and fouling pressure. Renew the coating when the minimum film has been consumed, significant fouling develops or the surface is damaged. A contrasting first coat can act as a wear indicator on self-polishing products.
