Interlux Topside Paint FAQ

Question: I want to paint the topsides of my boat using your products and wish to spray apply the paint. Which product should I use?

Answer: Premium Yacht Enamel and Brightside may be sprayed. However, Perfection contains isocyanates which are dangerous when sprayed and require the use of specialized breathing apparatus. We would therefore always recommend that a professional applicator is used for this type of application.

Question: What's the best way to get a good finish with topsides paints?

Answer: The quick answer is make sure you have carried out all the recommended surface preparation and priming. The product label contains basic details of what you need to do. However, there are a number of other things that you can do to make it easier to get the very best finish, every time. For a guide to the best way to apply Interlux topsides paints, and a number of related hints and tips, please refer to the topsides features section of the Boat Painting Guide.

Question: I'm doing a big project - painting the topsides of a bare hull. How do I know what products I need?

Answer: The time you will need for your project and what products you need will depend upon the size and type of your boat hull, its material of construction, its condition, and what paint scheme you decide to use. A detailed specification of required paints can be found by using the Paint Scheme Advisor section of this website, or for a quick reference table you may refer to the Boat Painting Guide handy specifications section, where you will find step by step tables for all hull types, and how much time you will need to do each stage.

Question: How do I know how much paint to buy?

Answer: The quantity you need will depend upon the size and type of your boat hull, its condition, and what paint scheme you choose to use. A detailed specification of required paints can be found by using the Paint Scheme Advisor section of this website, or for a quick reference table you may refer to the Boat Painting Guide "how much paint do I need?" section.

Question: Can topside paints be applied to below water surfaces?

Answer: Most topside coating systems if constantly immersed or kept wet will tend to blister. Provided the boat is only put into the water for a few days then a topside coating can be used below the waterline. Note that if you have a trailer boat with any carpet type material used as a padding against any top-side type coating then you may experience blistering in that area if the carpet remains wet for long periods. For trailer boats that are immersed for longer periods there is the question of "do I antifoul or not?" A possible answer here is to use an epoxy primer such as VC Performance Epoxy which is made for boats that do not need antifouling.

Question: Can I change the color of paint in the can?

Answer: The only way we recommend changing the color of our paints is to mix like paints, ie. Mixing Brightside with Brightside. We do not recommend addition of "universal" tints or pigments into our products. Yacht paint products are formulated to withstand harsh conditions and additions of universal tinters or any such products may affect water resistance, long term durability and may also slow down the drying time of the paint. We would also strongly discourage anyone from adding anything to antifouling paints that is not already mentioned on the label. Apart from affecting performance such additions may be illegal as antifouling paints are registered with a unique formula and addition of unauthorized materials, especially active ones to " improve " performance changes this unique formula.

Question: How do you paint Non-skid decks?

Answer: Interlux now offers three solutions for refinishing a non-skid deck:

1. Stir and apply Interdeck a pre-mixed, slip resistant, single component, ready to use deck paint that can be applied over Prekote primer or Epoxy Primekote primer 404/414.

2. Mix your own non-skid finish: any one of the Perfection or Brightside Polyurethane finishes can be transformed into a non-skid deck finish by the addition of Intergrip Polymeric non-skid compound 2398. Intergrip is made from small plastic spheres that have regular shape, low tendency to collect dirt and excellent non-slip properties. Once Intergrip has been added to paint general application directions are followed, except there is no need to sand between coats. Our two part polyurethane, Perfection, provides the most durable and long lasting finish for decks.

3. Hand Broad casting method - while the first of paint is still wet, sprinkle the Intergrip as required to obtain the texture of your choice. It is best to put the Intergrip in a flour sifter or salt shaker to dispense the compound. Avoid heavy application which will not assist in providing a more slip resistant surface. After the paint has been allowed to dry overnight remove the excess Intergrip and apply the second coat of paint.

Question: My boat is painted with single-pack paint; can I put Perfection on top?

Answer: Unfortunately not. As a general rule two-pack products cannot be applied over single-pack paints. The solvents in the two-pack are too strong and will soften the underlying coating.

Question: How do I paint my anodized aluminum mast?

Answer: It is difficult to paint over anodizing. If it is in very poor shape remove it before painting. To paint anodized first degrease using Fiberglass Solvent Wash 202. Then give it a heavy sanding using 60 or 80-grit sandpaper. Apply one thin coat of Vinyl-Lux Primewash 353/354 that has been thinned 25% with Vinyl-Lux Thinner 355. Wait 1 hour but no more than 24 and apply 1 coat of Epoxy Primekote 404/414 thinned 25% or Interprotect 2000E thinned 10-15% with 2333N. Allow to dry overnight and apply a second coat of epoxy primer. Sand and apply Perfection or Brightside.

Question: Why are two part paints better than one part paints?

Answer: Alkyd enamels, and modifications of alkyd enamel technology, have been the work horse products in the marine industry for approximately fifty years. Generally, they dry reasonably fast, are easy to apply and have very good weathering characteristics. More alkyd enamels are still used than any other enamel type. Their properties are well known to all experienced yachtsmen. They have been the backbone of the Interlux Product Line, and are respected by their tradenames - Interlux Toplac, Interlux Brightside Polyurethane, and Interlux Yacht Enamel. Today the fact that excellent finishes can be obtained from them with a minimum amount of effort is probably their biggest selling point. Two-part aliphatic polyurethanes, in comparison to alkyds, have superior properties, specifically: higher gloss and color retention, longevity, chemical and abrasion resistance and overall film integrity.
