Smart Strip – Remove layers of old antifoul!

Smart Strip Marine Strip

Like its alternative, Smart Strip Marine Safety Strip, Smart Strip Marine Strip is specifically designed for removal of marine boat bottom, antifouling paint, but Marine Strip is used on surfaces where the epoxy barrier coat is to be left intact. In a single application, the Smart Strip Marine Strip alkaline paste will strip all antifouling coatings on boats without harsh fumes or flammable solvents.

HOW TO REMOVE PAINT USING SMART STRIP™ MARINE STRIP

Smart Strip Marine Strip is a globesafe and environmentally friendlylead-based paint removal tool. Marine Strip easily clings to vertical and overhand surfaces, and once applied, it covers approximately 20 square feet per gallon. Follow these simple instructions when using Marine Strip for marine paint removal from wood, metal, and fiberglass:

  1. The Marine Strip paste is troweled or sprayed with a HD airless sprayer over the surface to be stripped.
  2. Smart Strip Marine Strip paste is then covered with our Dumond® Laminated Paper which controls evaporation and is left on until all of the paint is dissolved.
  3. When it is ready, place the paint removal tool under the Dumond® Laminated paper and scrape product from the surface.
  4. The stripped surface should be washed with clean water.
  5. Neutralize the surface using our new Citri-Lize Neutralizerincluded in the kit.

 

Smart Strip Marine Strip paint remover does not contain methylene chloride, MEK, or any other highly flammable solvents. As a non-toxic, eco-friendly paint removal product, there is no special ventilation needed when in use.

Changing away from Sigma Ecofleet 290 Antifoul

If you want to switch from PPG Sigma Ecofleet 290 Antifouling, it is quite easy. We have made the decision not to stock the Sigma antifouling paint range by PPG or their Ameron ABC3 Antifouling.

Jotun Seavictor 40 and many other Antifoul Paint brands will go right over Sigma Ecofleet 290. I will run through the Jotun process below for you, however the procedure will be the same for most other brands including Altex, Hempel, International, Wattyl etc.

After a good hard water blast, wash down with fresh water and wet sand with an 80 grit wet and dry sand paper. Try to remove most of the previous coat. Seavictor 40 can then be applied directly over the Sigma PPG antifoul without a barrier coat.

Any patches where growth may have exposed your epoxy layer of paint, these should be sanded, edges feathered and apply a coat of Jotun Vinyguard 88. Wait around 6-8 hrs for the Vinyguard 88 to dry and you can paint straight over with Jotun Seavictor 40.

Try to give your Jotun Seavictor 40 as much as 8 hours between coats, and two full coats of Jotun Seavictor 40 is recommended and a third coat around your waterline and leading edges. Wait 8hrs at 25 degrees and back in the water! It really is that simple to switch your Antifoul over to Jotun Seavictor 40 and 50.

If you have ABC3 Antifoul, it is a little harder to overcoat as it has strong solvents.

Jotun recommend a full barrier coat of vinyguard 88 and then you can switch your Antifoul over to Jotun. Same preparation procedure as above, after your hard waterblast with a turbo tip, try to remove as much of the ABC3 Antifouling paint as you can, then with a fresh water wash down, give the vessel a good wet and dry with 60 grit. Then apply a full coat of Vinyguard 88 as a barrier coat, wait 8hrs then apply your Jotun Seavictor 40 or 50, or even Seaguardian.

Any questions please feel free to call in store and we will be happy to run through the procedure with you in person.

Rolling and Tipping

If you have decided to paint your boat with a brush or roller it can be a little tricky if you have never done it before. We recommend you watch a few videos on the topic, read your data sheets for thinner volume and drying times. Plan your job so the surface is not red hot from the sun and drying the paint too quickly and use a retarder thinner in hot weather to give you more drying time.

Here are a couple of great instructional videos, if you search the internet for rolling and tipping you will find plenty of videos.

If you are having trouble, talk to the sales rep for the paint you are using, they can give you plenty of technical advice and tips. Try your first attempt off the job on a piece of timber or gelcoat before you have a go at your hull, so you can get a feel for the paint, it’s coverage, thinner amount required at various temperatures throughout the day. Ask us for the Altex 321 Brushing polyurethane, we stock it!
