A high-build two-part epoxy primer that dries fast, enabling application of a complete barrier system and bottom paint in just two days. Extremely effective for blister prevention on fiberglass, or as a bilge coating, because it is resistant to oil and water. It can be used as a universal primer for corrosion protection on most metals below the waterline such as props, keels, trim tabs, thru hulls and lower units or for priming any metal.

After the boat hull has been dried, properly sanded, and all hull blisters have been repaired, the boat is ready for primer application. The first thing to do is check your moisture meter to determine the amount of moisture in the hull itself. The hull should be as dry as possible.

Next, apply three consecutive layers of tape evenly at the water line each about a 60th of an inch lower than the one before. Remove one tape line between each coat to ensure a cleaner, low-profile waterline edge.

Each of the Tuff Stuff components must be thoroughly mixed with a power shaker until uniformly mixed before application. After shaking, stir the primer with the paint stick to ensure the coating is free of lumps. Proceed to mix Part 1 and Part 2 in a one-to-one ratio. Hand mixing is not recommended. Thoroughly mix with a jiffy mixer or equivalent.

Allow for a 20-30 minute induction time before applying the first coat of Tuff Stuff. During the induction time, clean the hull surface with S-80 Wax N’ Grease Killer to remove any impurities from the hull. Now you’re ready to apply the first coat of Tuff Stuff epoxy primer.

Once the first coat of Tuff Stuff is applied to the hull even, use the mill gauge to determine your wet film thickness. You should have about 10-15 mils of wet film thickness for each of the two coats of Tuff Stuff.

To verify that you’re ready for the second coat of Tuff Stuff, utilize the thumbprint test. Press your thumb firmly against the hull which will leave an indentation but no material should come off on your thumb. Then apply the second coat of Tuff Stuff preferably perpendicular to the first coat for a more even finish.

To ensure the best coverage, you should alternate colors of Tuff Stuff, grey and white. This is helpful to see the coverage as you’re applying it. You’ll notice the contrast between the grey and white Tuff Stuff coats. Be sure to properly mix the second coat of Tuff Stuff thoroughly and allow the 20-30 minute induction time before application.

To verify that you’re ready for the first coat of bottom paint, utilize the thumb print test again. If you wait longer than 24 hours after applying the second of Tuff Stuff to apply the first coat of bottom paint, you will need to apply a third coat of Tuff Stuff or sand the whole surface before applying the first coat of bottom paint.

Next, shake the Antifouling paint and you’re ready for application. The last step is to apply the antifouling bottom paint thoroughly and evenly. Two coats should be applied. And then a third coat at the water line. And with that, the Tuff Stuff application process is complete. Wait for overnight dry before launching your boat.
