A guide to choosing bottom paint for your boat | West Marine

As a boat owner, getting dragged to the depths of the ocean marine bottom paint for boats 50 a giant sea monster is probably not high on your list of concerns.

But make no mistake, there are some very foul creatures lurking beneath the waves. What you will see�and want to prevent�is the ugly, dirty, slimy mess they make on the bottom of marrine hull that decreases your speed and increases your fuel bill because your engine has to work harder. A fouled hull bottom is also a safety risk because it can decrease your ability to maneuver.

Battle the barnacles and other biofouling bottom huggers with the right bohtom paint for smoother sailing. The purpose of applying antifouling bottom paint is to prevent hard biofouling organisms like mussels, barnacles, and tubeworms, and soft growth like weeds and algae slime! Some coatings work better in different locations, including fresh or salt water. Some are more environmentally friendly than others, and some cost more based on the type of biocide and the protection they provide.

The key antifouling ingredient in bottom paint is some type of biocide for deterring hard marine growth. Some antifouling paints also include an algaecide for preventing soft growth. Biocide basics : For centuries, some form boatts copper has been used successfully to prevent the attachment of barnacles and other marine growth on hull bottoms.

Today, the type of copper most commonly contained in antifouling paint is either cuprous oxide or cuprous thiocyanate. Cuprous thiocyanate has the added benefits of being a lighter copper in terms of marine bottom paint for boats 50, so it produces botttom, truer paint colors. Also, paints using cuprous thiocyanate use half the amount of copper used in bottoom, heavier cuprous oxide paints.

Its secondary benefit is that it allows for the creation of brightly colored paints, unlike bottom paints containing cuprous oxide as the biocide. Teflon and vinyl bottom paints : Teflon paints are expensive, dry marine bottom paint for boats 50, cure to a very thin film, and are ideal for fresh water areas where algae is a problem.

Vinyl bottom paints are hard bottom paints that can be burnished smooth for racing, and are especially effective in saltwater, though not as effective as ablative paints for battling biofouling organisms. Both Teflon and vinyl bottom paints are used more to enhance performance, as in race boats, instead of antifouling. Deciding on bottom paint is a regional, sometimes section-of-the-harbor-specific choice.

Making that choice is made even harder because a bottom paint that works in one part of the harbor may not be as effective a few hundred yards away in that same harbor�even on the same type of boat. Bottom paints are usually one of two types: hard or ablative, with variations whose effectiveness depends on how much time the boat spends in the water, and how often it moves.

Hard bottom paints are typically less expensive than ablative antifouling paints. However, hard paints are bpttom for a single single season, and they build up season after season, eventually requiring costly removal.

Another problem for hard bottom paints is they lose their copper faster�and marine bottom paint for boats 50 effectiveness�if biats boat is kept out of the water fot than 60 days after applying bottom paint. For this reason, hard bottom paint marine bottom paint for boats 50 typically used on boats that marone in the water for extended periods.

Ablative bottom paint wears away gradually as water flows under the hull, either from use or tidal marine bottom paint for boats 50. As the paint wears away, it exposes a fresh burst of biocide to keep biofoulers from attaching to the surface. There are ablative paints for multiple season use, and others that are effective for a single season. The single-season ablatives are typically boast expensive than the multiple season ablatives.

For most ablative paints to work effectively, motion is required, so this paint is best if you use ffor boat fairly marine bottom paint for boats 50 least once a week. A hull painted with a single-season ablative antifouling paint can be pulled and left out of the water up to two weeks, but will require a light scuffing with a Scotch-Brite pad to reactivate the antifouling properties directly prior to launching.

A hull coated with a multi-season ablative marine bottom paint for boats 50 be pulled and left marine bottom paint for boats 50 of the water up to two weeks, without scuffing to reactivate the antifouling. However, after two weeks, scuffing is required directly before launching. Self-polishing, copolymer ablative bottom paint also wears botttom gradually to expose fresh layers of biocide.

Some copolymer ablatives can last multiple seasons, requiring only a light scuffing to reactivate the antifouling in the spring, directly before launching. Hybrid marine bottom paint for boats 50 ablative bottom paint has all the self-polishing, controlled-release biocide benefits of a copolymer ablative.

The difference bothom that it can also be burnished�like a hard bottom paint�for smoothness and speed, unlike other ablative bottom paints.

Your decision depends marine bottom paint for boats 50 answers to these practical questions. What type of hull do you have? For use on aluminum blats, aluminum bottom paint typically uses a copper-free biocide such as Econea.

Underwater metals such as outdrives and trim tabs also need this metal-free antifouling paint. Inflatable bottom paint is ablative, so it wears away gradually, and is designed not to crack or peel while the boat is being rolled up, or after drying. In terms of temperature, biofouling levels are typically pajnt in warmer waters than cooler waters. Fresh water biofouling, while not as severe as saltwater marine biofouling, still poses problems which are marine bottom paint for boats 50 if the water is brackish or polluted.

By far the biggest challenge comes from hard, marine biofouling organisms such as zebra marine bottom paint for boats 50 and barnacles, which destroy the marine bottom paint for boats 50 surface fkr allow moisture in, causing blistering and other expensive jarine. If moderate to heavy fouling is a problem in your region, you might consider a bottom paint that offers greater protection and lets you haul and relaunch without repainting, such as a multi-season paint.

In lower fouling waters, you can get adequate single-season protection from a more economical boata paint. The copper biocide cuprous oxide or cuprous thiocyanate or copper-free biocide Econea in these paints is designed primarily to combat hard shell marine growth.

If slime is a problem in your area, use a slime-shedding bottom paint boosted with a slime-fighting agent zinc pyrithione that controls slime growth at the waterline. How and when do you use your boat? For example, do you trailer your boat? If boahs, you should use a harder ablative bottom paint that can withstand trailering. Do you race it or just like to go fast? Try a hybrid copolymer ablative that allows you to burnish the surface, and provides good single or multiple season protection.

Do you go out every weekend? Every 5 Do you live in an area that restricts the use of solvent and copper-based bottom boata Other water-based ablatives contain copper for added antifouling protection, but offer easy soap and water baots.

How much money do you want to spend on bottom painting? With bottom paint, usually the more biocide, or different types of biocide, the greater the cost. Also certain properties, like self-polishing, single or multi-season effectiveness, or botas ability, require the inclusion of certain additives, which can increase the cost.

Length x Beam x. 550 heavily you apply the bottom paint is another factor in determining the quantity. The amounts below assume you want to coat the surface as thickly as possible without causing runs, and that you are applying two coats. Applying marine bottom paint for boats 50 coats of bottom paint up to the marihe waterline is a fairly straightforward task�if you know where the waterline is. Sometimes the line gets covered up by topside coatings, or it needs to be raised as bots boat gets outfitted for cruising.

gottom you may have a new boat and need to find the waterline. The safest and best way to do a DIY bottom paint job involves applying the paint with a brush or roller.

Due to the substantial toxic hazards, spraying is not recommended. To ensure the best possible bond and the most effective antifouling results, take time to assess the type and amount of surface preparation needed. Typically, most ablative bottom paints can be applied over hard paints, but not the other way.

Incompatible paints must be removed. Incompatible bottom paint or previous bottom paint that is extremely deteriorated should be stripped. Use a chemical stripper that works marine bottom paint for boats 50 bottom paint to remove it.

Just chip away any loose paint with a paint scraper or putty knife, then abrade with a marine bottom paint for boats 50 3M ScotchBrite padthen wipe the surface with a clean, lint-free cheesecloth, rag, or tack cloth dampened with acetone or mineral spirits or thinner recommended by the paint manufacturer to remove residual dust and grease, let dry, then apply masking tape.

If you need to sand, sanding makes a mess, so first lay fkr some drop cloths under and around your work area. Bohtom bottom paint also creates toxic dust, so use a dustless sander.

And protect your exposed eyes, skin, and lungs with high-quality protective equipment before you begin sanding. Use grit sandpaper to sand the entire bottom to smooth it out and remove any high or dor spots.

After sanding, wipe down the surface using the solvent recommended by the bottom paint manufacturer. After botom, and before painting, wipe the surface with a clean, lint-free cloth to remove any residual dust paaint dirt.

Getting great performance from your antifouling paint takes more than just completing the surface prep properly so the paint has every chance to bond mechanically and chemically to the hull. You also have to apply the paint when the timing is right in terms of temperature and humidity. Be patient and wait for the weather to cooperate. Before you start, pay attention marinee the dry time between coats and the recommended number of coats, as indicated by the manufacturer.

Also, be sure to check if there are any maximum limits on the amount of time the boat can remain out of the water after bottom painting and prior to launch. For example, copolymer ablative paints dry faster, which means their overcoating times are shorter.

They also have longer or unlimited launch windows. Bottom Painting. Algaecide basics : If you use your boat in an area where botom, algae, and grass growth on the bottom of your hull are common, you need an antifouling paint that also contains an algaecide to prevent this soft growth. In the past, some antifouling paints contained an algaecide called Irgarol, which is no longer being botom.

Irgarol was discontinued because of its persistence after release into the water, and harmful effects on marine life. Its effectiveness is similar to Irgarol, but it dissipates quickly marine bottom paint for boats 50 harmlessly into marine or fresh water ecosystems.

Zinc pyrithione is found in chemical solvent-based and water-based antifouling marine paints. It works constantly while the boat is in the water, regardless of whether the boat is moving, and stops working once all its copper biocide gradually leaches.

So the coating can still be in great shape, but the biocide is gone obttom so is the protection. Water can seep in to the unprotected coating and damage the hull. For the cleanest line, try to position the tape as close to the bootstripe as you can, beginning paont a natural start point in the line. Draw cor tape out slowly, outlining every 1.

These paints work well in high-growth areas and continue to be effective after haulout at the end of the season. This is a huge time-saver for those living in northern climates. While the percentage of copper in the paint is important, it is not the only consideration. Controlled polishing, the technology that controls how quickly the paint wears away, also contributes to the effectiveness of these paints.

If you choose a copolymer paint, we recommend two or three coats on the first application. Copolymer paints with anti-slime additives are best for heavy fouling areas. Ablative paints of the non-copolymer type work in a similar way and minimize the annual ritual of sanding when applying a fresh coat.

Best use is as a single-season paint for boats that are used often, but are not serviced by a diver. Not recommended when you want a super-smooth bottom finish and have a diver maintain it, since scrubbing removes paint and reduces longevity. Some paints are recommended for freshwater, while others are not.

For example, Interlux's Micron 66, which depends on a reaction with saltwater to be effective, should not be used in freshwater. Other paints, such as Pettit's SR favored for racing boats is best suited for freshwater or short-term use in low-fouling, cold saltwater areas.

Frequently used boats may want to use an ablative paint, which will get smoother over time and will shed light growth. Infrequently used boats may want to use a modified epoxy paint that will have good antifouling properties when the boat is inactive. If you keep your boat in the water year round you are most likely a candidate for a high-copper-content modified epoxy paint that prevents growth by leaching biocides upon contact with water.

Higher copper content, rather than the type of paint binder as with ablative paints, generally means greater effective performance in this paint type.

Modified epoxy paints adhere tenaciously to most surfaces and can be applied over most types of paints�except vinyl-based paints. Since hard, modified epoxy paints do not wear away, an egg shell-like buildup will occur over successive haulouts. Eventually you will need to "bite the bullet" and undergo the not-so-fun task of stripping away the paint. Choose a copolymer paint that remains effective for and indefinite period of time.

Because they expose new biocide until the coating is worn completely away, additional coats add to their longevity. We use cookies to optimize site functionality and improve your overall experience.

Other times, you might have to sand them off. I use a random orbital palm sander with a 6-inch disc. I prefer using about grit. It is coarse enough to remove paint quickly but not so coarse as to dig in too deep too quickly. As with woodworking, you want to start the sander before putting it on the hull and then keep it moving so it does not remove too much material in one spot.

Sanding is generally tedious and some of the positions in which you find yourself will be uncomfortable. When you are all done with that, dispose of any collected dust and debris in an approved manner.

This is a matter of local environmental regulations and just plain common sense. You may also want to throw away your coveralls as they will be very dusty. For the best quality job, you will want to purchase good quality brushes and rollers. At the same time, it will probably not be worth the effort to clean your rollers and brushes at the end of the job.

I choose to just throw those away along with the pour spout, rags, and disposable gloves. I do keep the roller handles, extension rods, and plastic painting tarps. I also wear Tyvek coveralls but not the same ones I might have used during sanding.

I will reuse my painting my coveralls until they become too damaged for use. I also wear safety glasses. If you have to get paint off your prescription glasses, it can damage the lenses and coatings. So for the tools that you can reuse, it is worth buying good quality. For items that will be used only once, buy good quality but not top of the line. You will need and want a warm, clear, calm day.

Bottom paints need to be applied generally when the temperature is at least 50 degrees Fahrenheit. The manufacturer will say that that should be the minimum temperature for 2 days or more until the paint has set up, my experience is that as long as it is 50 when you paint and does not drop below freezing for at least 2 days, the paint will do fine.

I have seen marina staff paint a boat and immediately launch it. Next I spread a plastic drop cloth and keep moving it to keep it underneath the area on which I am working.

NOTE: some marinas will put down a ground cover for you when your boat is hauled out. Of course, there is a cost but that is a decision you may be able to make. My preference is to start from the rear since all of the more complicated structures like the rudder and the through-hull box from which the prop shaft exits are in the back.

Work from the wet edges. I do not worry about the complete underside of the bulb keel but I will do the underside of wings and under the front of the bulb. Do NOT attempt to move jack stands on your own when you paint. Coordinate with your marina to have their staff move the stands or alternatively, the marina may paint the areas under the jack stand pads when they launch the boat. Bottom paint is expensive. If you have any left over, seal the can well and you will be able to use it again.

This is where the pour spout is most useful. Using it keeps the top of the can clean and lets the lid reseat fully and firmly. I have used my left over paint 2 years later with no problems.

It had not even skinned over. This may be a little bit of a challenge next time because the type of paint I have used the last 6 years has been discontinued. I will need to find a compatible replacement both in terms of bonding to the current paint and mixing with the half gallon of my left overs. All the rollers, brushes, disposable gloves, and even the pour spout should go into a heavy duty plastic bag that gets tied closed securely and then put into the appropriate waste container.

Check with your marina for information on proper disposal. Check out Spring Prep Gear for bottom paint options. Painting prep and painting can be physically tedious but your bottom needs fresh paint for best performance. If you do the job right, your bottom paint could last more than one season, especially on sailboats. The ablation that occurs is likely to be more pronounced on power boats owing to the higher speeds at which they travel through the water.

In any case, inspect, prep, and repaint as necessary. Likewise, check your sacrificial zincs yearly. You will probably have to replace them at least once a year. Subscribe to my YouTube Channel for more how-to videos, sailing excursions and more! When adding a top or bottom coating to your boat, it would probably help to hire a professional. I have found Marine Paint For Boats Bottoms 80 the cost of have the marina prep and paint my foot sloop to be somewhat cost prohibitive.
