If you store your boat in the water at least part of the year, keeping the hull free of marine growth with one or more coats of quality antifouling paint is critical to keep it performing its best�and for reducing fuel costs. This preventative maintenance task should be at the top of your list. A clean hull is safe, fast and efficient�while a fouled teflon paint for boats youtube will reduce your boat's speed, maneuverability and cost you more at the fuel dock.
Knowing which products to select and how to tef,on them can save you hundreds of dollars over the cost of paying a yard to do the work. If you plan on painting over an existing coat of yutube paint, the paint you select must be compatible with the paint you choose.
If the job will be confined to applying bottom paint no barrier coatyou will need the following tools and supplies:. When hauled out for a bottom job, allow extra time for chores such as disassembling and lubricating seacocks, replacing worn transducers noats inspecting rudder bearings.
You may want to pull and inspect the propeller shaft and bearings. Sometimes the weather does not cooperate. It may be too cold, too hot, too humid, or too windy to start a job. In that case we recommend you wait until conditions improve. The results will be worth the extra time.
Not only will the coat of paint look better, it will deliver better pzint performance and it will last longer. Antiflouling paint prevents marine organisms such as barnacles and zebra mussels, weeds, slime and teflon paint for boats youtube from attaching themselves to the hull.
Antifouling paint choices tend to be regional, with boaters in the Great Lakes, Pacific Coast, Youube, Gulf Coast and other areas choosing similarly to their neighbors in the local marina. Using the same paint as your neighbor might work well for you, however you should also consider how you use your boat and the teflin of paint you applied in the past, since there can be compatibility problems between different formulations.
In general, softer paints can be applied over harder paints but not vice-versa; vinyl paints should only be applied over vinyl paints. If you use your boat frequently, a copolymer ablative paint might be for you. These paints offer several advantages over hard modified epoxy paints. This feature reduces paint build-up and the need for sanding at haulouts. The second advantage is that in general, unlike hard modified epoxy paints, copolymer-ablative paints do not lose their antifouling ability teflon paint for boats youtube exposed to air; which means that prior to winter storage, you can paint your boat and be ready to launch in the spring.
Light sanding or scrubbing may be necessary prior to launch. This is a big time-saver for those living in northern climates. Another advantage of copolymer ablative paints is that although they are loaded with less copper compared to modified epoxy paints, controlled polishing enables them to use their copper content more efficiently. Because they expose new biocide until the coating is worn completely away, additional coats add to their longevity.
Pettit Hydrocoat offers the added benefit of being a water-based product with no solvents, an environmental plus, so there are fewer fumes to protect yourself teflon paint for boats youtube and easier clean-up using only water. White copper produces the brightest colors, whitest whites and blackest blacks.
ECONEA is a metal-free biocide that, depending on the paint formulation, can be as effective as cuprous oxide Deck Paint For Boats Youtube at about one tenth the concentration in paint by weight. This results in a brighter range of colors compared to darker cuprous oxide based paints. If you keep your teflon paint for boats youtube in the water year round, you are most likely a candidate for a hard, high-copper-content modified epoxy paint that prevents growth by leaching biocides upon contact with water.
Higher copper teflon paint for boats youtube generally means better performance in this paint type. Modified paijt paints adhere tenaciously to most surfaces, and can be applied over most types of paints. Since modified epoxy paints unless scrubbed frequently by a diver do not wear away, build-up will occur with each new coat and eventually your hull will need to have the coating stripped. We used blue Pettit Trinidad SR on our 30' Newport sailboat, kept in a year-round marina, and had great results with the product.
Interlux Ultra is a similar high-copper paint. Two affordable and popular modified epoxies are West Marine BottomShield and Interlux Fiberglass Bottomkote NT, which are budget choices compared to more sophisticated ablative paints or high-copper modified epoxies. These formulations use less copper more efficiently teflon paint for boats youtube to modified epoxy paints. Freshwater locations like the Great Lakes are plagued primarily by algae, and thin film paints such as VC 17m Extra and are a good choice for these environments.
They offer a super-slick PTFE finish to keep growth from attaching to the hull, in addition to one or more biocides. They dry almost instantly, so you can rapidly apply several coats and launch almost immediately. Because they are so thin, they must be applied with either a solvent-resistant foam roller cover or by spray with an airless sprayer. Racing sailboats used in freshwater are teflon paint for boats youtube especially good candidate for these paints.
Like ablative paints, sloughing antifoulings wear away as the psint moves, so the more often the boat is used and the faster it goes, the quicker the paint wears off. Sloughing paints are very soft, so few paints can be applied over. Vinyl-based paints are slick, hard paints that can be burnished to provide a smooth surface preferred by owners of performance boats.
Unlike thin-film paints, vinyl paints like VC Offshore teflon paint for boats youtube be used in salt-water, although their antifouling effectiveness is inferior to reflon modified epoxies and ablatives. Vinyl-based paints can only be applied over an existing vinyl paint. Very thorough sanding is required to achieve a good bond when painting over vinyl coatings with other types of bottom paint.
Never apply an antifouling bkats that contains cuprous oxide on an aluminum hull or outdrive. Doing so will result in galvanic corrosion that will damage or even destroy the hull. For painting underwater metals, Propspeed has emerged as one of the most popular formulations on the market today. Propspeed contains no biocide teflon paint for boats youtube all. Teflon paint for boats youtube, it is a super-slick coating that easily sheds marine growth.
Propspeed is used on underwater metals, including props, struts, shafts and keel coolers. The big news here is that the popular anti-slime additive Irgarol is, after an absence of several years, back!
Irgarol disrupts photosynthesis in plants, which makes it an effective additive for controlling slime and preventing that ubiquitous waterline "beard". Micron Extra by Interlux is panit example of this type of paint.
Other choices include paints boosted with the anti-slime biocide zinc pyrithione, also called zinc omadine. Youtibe restrictions on copper-based antifouling paints increase, a pharmaceutical alternative has emerged. Depending on the paint formulation, ECONEA can be as effective as cuprous oxide at about one tenth the concentration in paint by weight.
Good preparation and priming are the basis for any paint job and antifouling paints are no different. Solid prep ensures good adhesion and better performance over time. If you are painting a new boat for the first time, wipe down the entire bottom with a good solvent wash such as Interlux or Pettit Dewaxer to get rid of all mold release agents from the factory.
To avoid just spreading the mold release agent over the hull, turn your cloth frequently and replace often with a clean cloth. You can then lightly sand the youtubf with grit sandpaper or use a no sand primer instead, such as Interlux Fiberglass No-Sand Primer or Pettit Sandless Primer. However, since most of us will be recoating over a previously painted bottom, we will need to make sure the surface is prepped for another coat.
If teflon paint for boats youtube old paint is known and in good shape: Remove old loose paint, dirt, grease, youthbe marine growth with a power washer, brush or scraper. Wipe down with solvent wash. Sand with grit paper. Exercise caution to avoid sanding through a barrier coat that may have been applied to prevent fiberglass blistering or damaging the gelcoat of the hull.
Repeat solvent wash. Clean laint the thinner recommended by your paint manufacturer. If blister protection is not needed, you can apply paint directly to the sanded surface or the fiberglass.
If the old paint is unknown teflon paint for boats youtube in good shape: Clean, remove loose paint, sand grit paper and rinse with water. Apply the recommended number of coats of tie coat primer such as Interlux Primocon or Pettit to ensure optimum paint adhesion.
Some slippery Teflon paints such as the Interlux VC Offshore series may need to be removed before applying an incompatible paint. If teflon paint for boats youtube old paint is unknown and in bad shape: Remove the boars coats of antifouling paint.
Teflon paint for boats youtube paint remover that is compatible with the material of your hull. You may have to apply the paint remover several times to get rid of all the layers.
If you are a racer or a stickler for a super-smooth bottom, the dreaded sanding longboard may have to come. Once the paint is stripped, check for damage to the barrier coat that provides blister protection if there is one and patch it where necessary. If the hull does not teflon paint for boats youtube an epoxy barrier coat this is a good time to consider applying this protection. Then proceed with painting. Power-washing works great to remove any remaining dirt or light fouling.
Be sure to wear eye protection, a good respirator and rubber gloves, as the cleaner is very caustic. Once the surface has dried completely, we are ready to sand. Bottom paints are toxic by nature and most are solvent based, so you should always try to cover exposed skin, shield your youthbe and wear a respirator to avoid breathing toxic fumes.
We recommend outfitting yourself with a disposable coverall suit, gloves, high quality goggles and a dual-cartridge respirator. Now get to work! First, lay out a large tarp or dropcloth to cover the entire work area.
Knock off any loose paint with a scraper and, using either a sanding block or a dustless DA sander, lightly sand the entire bottom with grit sandpaper.
Spend a little extra youtibe on any high or uneven areas. Try to achieve as smooth of a surface as possible to minimize underwater drag. Work around transducers, prop shaft struts and outdrives. When you have finished sanding, wipe down the surface with a rag and some solvent wash.
There are some things to keep in mind when selecting a tape. General purpose tapes are only designed to be left on a surface for 24 hours or less, unless you want a lengthy job Teflon Paint For Boats Uk of trying to remove the tape! Try to tape as close to the existing bootstripe as possible. Start from a natural break point in the line and draw the tape every 1.
My large anchor is iron with 3 tongues which unequivocally puncture in to a underside when sloping during an point of view. get proposed as you speak?
