VELOX PLUS – 0.5 LITRE – 3 COLOURS AVAILABLE

Velox Plus is an easily applied hard vinyl-based anti-fouling paint for the protection of propellers, shafts, rudders, trim tabs, stern drives and other metal parts permanently immersed in water.

With excellent adhesion qualities against electricity and water pressure, Velox Plus is easy to clean in situ and resistant to damage from stray lines.

It is suitable for parts made of bronze or similar alloys, steel, aluminium and metal parts treated with factory paint (for example aluminium stern drives).

Velox Plus is an anti-fouling suitable for the protection of propellers, shafts, rudders, trim tabs, stern drives and other metal parts permanently immersed in water. Thanks to its combination of soluble and insoluble resins and its additives, it provides excellent adhesion to all metal surfaces and good anti-fouling power. It is suitable for parts made of bronze or similar alloys, steel, aluminium and metal parts treated with factory paint (for example aluminium stern drives).

Thanks to its combination of soluble and insoluble resins and its additives, it provides excellent adhesion to all metal surfaces.

It provides resistance to galvanic currents, that are the main cause of film detachments.

Velox Plus is the most appreciated product of the entire Marlin range and is currently exported all over the world, from America to Australia, from Europe to the Far East. ​Tens of thousands of boats successfully use Velox Plus, a rapidly growing number both in Italy and abroad thanks to the excellent results obtained, the growing demand and the expansion of the distribution network. ​Velox Plus complies with the strictest regulations and has recently been approved by the environmental protection bodies of the United States and Australia, considered among the strictest in the world. 

In applying Velox Plus, as well as Marlin Paint’s Metal Primer, Boating Products also recommends the one-off use of our two-pack Etch Primer, where the metal substrate has been subject to silicon saturation. 

Velox Plus protects underwater metals from marine growth for 1-2 years, assuming;

• Regular use of your boat, which is 1 to 2 times per week.
• A galvanic isolator is in use for protection above 0.4V where necessary, noting battery charging full time, solar panels or wind generator may generate electrical discharge causing galvantic issues.
• Substrates are prepared properly and the product is applied as directed. 
• • Where you are applying Marlin’s Metal Primer on to bare metal please note the preparation relative to an etch primer

  Boating Products Etch Primer

  In AU/NZ we recommend the use of our 2-part zinc-chromate etch primer, in addition to Marlin Yacht Paint’s Metal Primer/Velox Plus. Why;

  • Locally there is extensive use of silicon foul release. Silicon contaminates the metal strata, causing adhesion issues for the Metal Primer. Etch Primer completely mitigates this problem. Therefore, when moving away from silicon foul release, we highly recommend using Etch Primer before using Metal Primer.
  • The further problem is locally many people do not know the difference between brightening metal vs a physical key (noted below as 80 grit garnet). If in doubt, use Etch Primer before using Metal Primer to completely mitigate this problem. 
  • It is almost certainly not required when dealing with aluminium factory coating or epoxy primer surfaces. 

  Surface Preparation

  • For new propellers or other bare metal parts, go directly to next point. Pressure wash with fresh water and remove all existing antifouling or other coating using sandpaper 80 grit, manually or with careful use of a dual action rotary sander (we suggest using a soft pad in order not to damage the propeller). Do not remove old VELOX PLUS from previous season. Do not remove factory finish from aluminium stern drives. 
  • Sand thoroughly all metallic surfaces with dry sandpaper 80 grit garnet, renewing it often. A dual action rotary sander can be used. Do not use wet sandpaper. The surface must be very rough after sanding. Do not use coarser than 80 grit, nor finer, nor worn out sandpaper. Do not use Scotch Brite. We do not recommend sandblasting unless done by an experienced professional.
  • Wash and degrease carefully all metallic surfaces with a Grease & Wax Remover and a clean rag. Change rag frequently, especially in case of new or folding propellers, which usually have more grease on them.
  • NEVER use acids, other solvents, water, detergents, soaps. 
  • Note – We suggest protecting bare aluminium with an appropriate epoxy primer (typically 3 coats). This is not necessary when aluminium is already protected with factory finish (like new stern drives). On epoxy coatings or on factory finish, just lightly sand the surface with abrasive pad (like Scotch Brite) or fine sandpaper (180-220 grit) and apply METAL PRIMER.

  Application

  • Where applying ETCH PRIMER, apply a light, thin coat. Leave at least 30 minutes – but not more than 5 hours – before proceeding to the next next step.
  • Apply one coat of METAL PRIMER (maximum wet film thickness 100 µm, dry film thickness 35 micron). We suggest application with a small/medium brush. Leave it dry for at least 3 hours at 20°C. A light coat is enough, applying thicker coats than recommended may result in worsened adhesion. 
  • • Note – On top of VELOX PLUS from previous season, another 2-3 coats of VELOX PLUS can be applied directly as explained above, after cleaning and lightly sanding the surface with fine sandpaper or abrasive pad (like Scotch Brite). We suggest removing all the antifouling paint in any case at least every three years, subject to monitoring. Do not apply METAL PRIMER (except to touch up) or VELOX PLUS on any other antifouling. Do not apply VELOX PLUS on bare metal without METAL PRIMER.
  • Apply one coat of VELOX PLUS by brush (wet film thickness 100 µm, dry film thickness 35 µm). Apply it with continuous long brush strokes. Avoid going back and forth on the same spot, as this will soften too much the METAL PRIMER. Full coverage will not be achieved with first coat of VELOX PLUS. The first coat will normally slightly soften the primer, showing some of its green colour.
  • Wait at least 3 hours at 20 °C then apply a second coat of VELOX PLUS (wet film thickness 100 µm, dry film thickness 35 µm). For best result, apply it by brush with long and continuous strokes, perpendicular to the brush strokes of the first coat. 
  • For complete converge, we recommend a third coat of VELOX PLUS, again perpendicular to the second coat.

  Drying Times

  	10°	20°	30°
  Dust Out	30 min	20 min	15 min
  Touch Dry	3 hours	2 hours	1.5 hours
  For Re-coating*	6 hours	3 hours	2 hours
  For Launching*	24 hours	12 hours	8 hours

  *If possible, we recommend letting both METAL PRIMER and VELOX PLUS dry well between one coat and another and before launching, especially in cases of high humidity or low temperatures. The ideal is to apply one coat of product per day and wait two days for launching.

  Suggestions to follow

  • When preparing bare metal for METAL PRIMER the surface should be keyed to 80 grit. Contrast this to ETCH PRIMER, where chemical bond requires less keying.  80 grit gives approximately 120 micron profile, resulting in 80 micron score in the metal.  
  • NEVER use acids or acid-based products to descale or clean the metal surfaces before applying the METAL PRIMER (for example, the products normally used to dissolve barnacles or are acid-based).
  • Do not use detergents, dirty solvents, or water to wash the surfaces after sanding.
  • Do not touch the surfaces with bare hands before applying the METAL PRIMER.
  • For cleaning the surface, use only wax and grease remover or equivalent with clean cloths.
  • Do not apply in case of extreme humidity and/or strong temperature changes. Watch out for dew point and condensation on metals, especially early in the morning. If in doubt, the metal parts can be dried with a jet of hot air and the surfaces washed with a wax and grease remover or equivalent.
  • Do not apply the product with temperatures below 5°C or above 38°C. In case of temperatures below 10°C it is important to wait at least 48 hours for launching after the last coat.
  • The minimum drying times are indicative, it is always advisable to let the product dry for as long as possible between coats in any situation. Beware of high humidity, which significantly lengthens drying times. Whenever possible, we recommend waiting up to 24 hours or more between coats.
  • To obtain an excellent result, the preparation of the surface is essential, which at the time of applying the METAL PRIMER must be very rough (the rougher it is, the better adhesion you will have) and clean, free from grease, dust or other dirt (even fingerprints sweat or traces of solvents or water).
  • Never apply VELOX PLUS over any other type of antifouling or directly over bare metal.
  • The product is ready to use, it is strongly advised not to dilute both METAL PRIMER and VELOX PLUS.
  • Mix very thoroughly before use. The product may present a marked separation due to the heavy pigments present in the formulation.
  • It is advisable not to stay connected to the electricity outlet when at mooring. Strong galvanic currents significantly reduce the effectiveness of antifouling for metal parts and can cause severe detachments.
  • Bare aluminium parts without the factory paint must be treated with an anticorrosive epoxy cycle (e.g. 2-3 coats of epoxy primer) before applying METAL PRIMER.
  • The treatment of the propellers and metal parts is delicate, we recommend that you do it before the other jobs in order to have enough time to do it in a workmanlike manner.
  • Respect the recommended quantities to obtain a good result. The product is ready to use, the use of thinner is not recommended.
  • In case of antifouling application several months before launching, it is preferable to keep the boat away from direct sunlight and rain (for example with a black plastic bag).
