What is a flattening agent?...Flattening agents can be added to both Interlux finishes andvarnishes; and depending on themix ratio between the product andthe additive, a variety of gloss, satinor matt effects can be achieved.Interlux produces two types of flattening agent, suitable for usewith either the two-part or one-partproducts in the range.

What is Intergrip No Skid Compound?...Intergrip No Skid Compound is a synthetic, granular material thatcan be added to topside finishesprior to application or sprinkledonto wet paint as an aid toproviding a more slip-resistantfinish. As with the flattening agents, the final result isdetermined by theamount of materialadded into the finish.

How to prepare bare substrates

Before You Start

Health and safety precautions for paint productsare a legal requirement and form a specificsection on our labels and is often difficult tounderstand. This section is intended to help youunderstand the information in our literature and on our product label to make applying paint asafer job. Before starting work always read thelabel which will indicate those areas whereparticular care should be taken. Other generalsafety precautions are detailed below and willhelp should any problem occur while usingour paints.

Personal health

Avoid ingestionFood and drink should not be prepared or consumedin areas where paint is stored or used. In cases ofaccidental paint ingestion seek immediate medicalattention. Keep the patient at rest, do NOTinduce vomiting.

Avoid inhalationBreathing solvent fumes can make you dizzyand could result in collapse.

The inhalation of solvent vapor from paint orsanding dust, can be reduced with adequateventilation or extraction but may not be sufficient,suitable respiratory protection should always beused. In badly ventilated areas wear an air-fedhood or cartridge respirator with an organic vaporfilter. Wear a cartridge type respirator whenabrading old antifoulings – never burn off ordry-sand antifoulings as this may create harmfulfumes or dust. Spray painting creates additionalhealth hazards and respiratory protection shouldalways be used. Air-fed hoods provide the bestprotection but read the label carefully and ensurerecommended protection is worn.

Avoid eye contactEye protection should be used during paintapplication and when there is any risk of paintsplashing on the face. Safety glasses that complywith ANSIZ871-1989 Standard are inexpensive, easilyavailable and are well worth wearing. If material doescontaminate the eye, flush the eye with clean freshwater for at least 15 minutes, holding the eyelidsapart, and seek medical attention.

Avoid skin contactTo avoid skin irritation always wear protectivegloves and clothing to cover the body and a barriertype skin cream to cover the face. Do NOT usepetroleum jelly as this can help the absorption ofpaint into the body. Remove rings and watches thatcan trap paint particles next to the skin. Removepaint that does get on skin with warm water andsoap or an approved skin cleanser. Never usesolvent to clean the skin.

Health & Safety

For further information on Personal Protective Equipment.

Risk of fire or explosion

Most paints contain organic solvents – some of whichevaporate into the air upon opening the container. Any dangers can be reduced if a few simpleprecautions are taken:

n Avoid naked flames where paint is being stored,opened or applied

n Do not smoke

n Store paint in a well-ventilated, dry placeaway from sources of heat and direct sunlight

n Keep the tin tightly closed

n Avoid sparks from metals, electrical appliances beingswitched on and off, or faulty electrical connections

n Do not leave paint soaked rags lying around,in the pockets of overalls or in waste bins. Sometypes of paint can dry out and auto-ignite.

Key points to note when applyingfinishes and varnishes:

n Dry, well ventilated conditions are preferablewhen applying finishes or varnishes. While gentleair movement will assist the drying process, a dust-free environment is critical to achieving a good quality gloss finish; always avoid painting in windy conditions.

n The effects of dust contamination may be furtherreduced by sanding lightly between each coat,removing residual dust by wiping down with asuitable solvent and allowing to dry beforeapplying the next coat. This will also help improve the initial aesthetics.

n Avoid applying two-part finishes or varnishes late in the afternoon or when relative humidityexceeds 80% as these products are particularlysensitive to moisture. Condensation duringapplication or due to overnight ambienttemperature changes can affect the chemical cure of these products resulting in loss of gloss.

n When painting orvarnishing wood avoid applying if theambient temperatureis increasing (orpredicted to increase)significantly.

Choosing a faster drying product or system, where available, will help to minimize the windowfor dust contamination.

This is because rising temperatures cause woodto expand, which can lead to blisters forming inthe paint or varnish film. A good tip is to applywhen the temperature is falling, as the wood willbetter absorb the paint or varnish, giving betteroverall results.

Key points to note when applying epoxies (e.g. Watertite, InterProtect®,Epoxy Primekote)

n When curing in high humidity conditions,particularly at lower temperatures, epoxies candevelop an ‘amine blush’ on the surface. Thisslightly sticky substance must be removed andcan normally be washed off with soap and water.If the blush is not removed it can lead to thedelamination of subsequent coats. Failure toremove the blush will also make sanding moredifficult.

n High humidity conditions can reduce the amountof solvent evaporation during the drying/curingstages; with epoxies this can lead to a ‘softcure’. As epoxy-based materials are generallyapplied at a higher film thickness, solvent canremain trapped in the film for many days leadingto slow or poor final cure.

n Although epoxies generally cure well in mostconditions, when the temperature falls to 45°F or below, curing can slow or even stop.Remember to check both day and overnighttemperatures whether working outdoors or in a shed.

n Epoxy products usually respond well to a littleheat; on cold days introducing a safe form ofheating into the application area is well worthconsidering.

Always check the weather!When painting outside, always check what weather conditions are anticipatedduring the preparation, application and drying phases of any project. Should fairweather prevail, whether or not to commence painting will then depend on the air and surface temperatures, humidity and dew point.

You may find the following hints and tips helpful when planning your project –further, product-specific guidelines can be found on individual product labels and data sheets.

19

General Guidance Notes:

n Dew point is important when applying paint to a surface, as the evaporation of the solvent fromthe paint draws heat and/or energy from thatsurface, cooling it down. If conditions are rightcondensation may form on the surface of thepaint resulting in various problems.

n Relative humidity is important as air can onlyhold so much water or solvent vapor at any onetime. So, as the relative humidity increases, thelevel of solvent vapor the air can hold reduces,meaning paint will effectively dry more slowly.

n Air and substrate temperature will affect thedrying properties of any paint. Failing to observethe recommended drying times can result incoating failure, including improper drying,wrinkling and loss of adhesion.

n Always avoid extreme air or temperatureconditions; Interlux products are tested across a range of temperatures, to ascertain the dryingtimes and application characteristics of eachproduct. Drying time recommendations areprovided on our products labels; furtherinformation relating to weather considerationscan be found on our product data sheets,available on our web site.

n Low temperatures will increase drying times;always check the ‘through-dry’ of each interimcoat, before sanding or overcoating.

n Sanding too early can cause the paint to wrinkle under the sand paper, in some caseseven tearing or gouging into the paint filmmaking refurbishment difficult. Sanding beforethe paint film is ‘through-dry’ can also clog thesand paper, meaning more sheets are needed to complete the task.

n Overcoating too early can cause wrinkling,blistering and loss of gloss in the finished paint job.

n High temperatures will reduce drying times, but can make application more difficult, asproduct flow and leveling can be compromised –particularly when applying finishes or varnishes.Where appropriate, thinning recommendations to help with higher temperature application areprovided on labels and data sheet.

n Do not paint in direct sunlight, or when thesubstrate itself is excessively warm, as theresidual heat of the substrate can adverselyaffect the application and drying properties ofany paint product; this can result in poor flowand leveling, rapid drying, cracking and loss ofgloss. Surface temperature can be measuredusing a surface thermometer.

When applying two-part products in highertemperatures the pot life of the product will also be affected, reducing your work time window.

Remember that surfaces heat up and cool down ata different rate to the surrounding air temperature,meaning even though the ambient temperaturemight seem warm, the temperature of the surfacebeing worked on may still be quite cold. Very oftenone side of a boat will be in the shade and theother in bright sunlight meaning the applicationconditions will differ. Additionally, in the morningthe surface temperature of the sunny side willgenerally be lower than the ambient temperature,whereas in the afternoon it may be higher.

Stuart JordanSpecialist in Epoxies/Fillers Development

Making small repairs to fiberglass surfacesWhen working with fillers it’s important to remember that epoxy fillers arerecommended for both above and below the water areas; polyester fillers aresuitable for use above the water only. Interlux Watertite is a two-part epoxy filler,suited to most DIY repairs above and below water.

See Page 32 for sandpaper guidelines.

Once cured, sand with 80-220 grit paper. Thefinished repair should be smooth and level with thesurface. If required a second layer of filler may beapplied, repeating the same process. The repairedarea can then be primed, ready for painting.

“Working with epoxy fillers?”n Two-part epoxy fillers are the most widelyused fillers in the yachting industry. They areinvariably solvent free. A benefit of beingsolvent free is that they do not attack theunderlying primer.

n Epoxies must be mixed in the proper ratio. Too much curing agent and they will leave asticky film on the surface that is not suitable forovercoating. Too little curing agent will weakenthe filler and cause it to crumble later on.

n Below the waterline, epoxy fillers must beused. Polyester fillers should not be used asthey have a greater propensity to absorbwater.


Health and Safety

Removing aged finish4

Prepare according tosubstrate, followingbare substratepreparation guidelines.

Preparation5

Removing antifoulingIf your existing antifouling is in poor condition, we recommend removing it completelybefore repainting. Interstrip 299E has been formulated for removing antifouling fromall substrates and is safe to use on fiberglass without harming the gelcoat.

“Hints to help you achieve aperfect finish.”n We do not recommend using a chemical paintstripper when working with fibreglass, unlessthe product has been specifically approved forthis purpose. Non-approved paint stripperscan damage the substrate.

n When working with wood, always work in thedirection of the grain, whether sanding orapplying varnish. This will avoid scratchesthat can still show through, even after manycoats of paint or varnish.


See Page 32 for antifouling application advice.

For best results, work on a small area at a time –do not allow the product to dry out. See productlabel for more information.

Remove while still softwith a blunt scraper.Interstrip 299E canremove several coatsat a time, but heavybuild up may requiremore than oneapplication. Residueshould be disposed of according to localregulations. Reapply fresh antifouling after sandingand priming the hull.

Removing old antifouling4

Leave on the surface.The product needstime to work; the timeneeded will varydepending on thetemperature and theamount of oldantifouling on the hull.

Preparation

High pressure fresh water wash, to remove looseantifouling; ensuring all residue and wash water is contained and disposed of, according to locallegislation. Mask off areas to be stripped.

2

Applying Interstrip

Apply Interstrip 299E liberally, using an old brush,following the application guidelines provided onthe product label.

3

“Is your existing antifoulingin good condition?”If your existing antifouling is in good condition, it may not need removing and can simply beovercoated, following a high pressure freshwater wash. Always ensure you check forcompatibility before applying new antifouling;incompatible or unknown antifouling should besealed with Primocon. See Page 36 for moreinformation on antifouling compatibility.

Alex TrogeSpecialist in Finishes Development

“Achieve a perfect resultevery time!”n Ensure an even spread by holding the brushat 45° – this minimises brush marks.

n The best finish is achieved on large areas bytwo people, one to apply the paint, the otherfollowing immediately behind to ‘tip off’ thefinish.

n Clean or change brushes every 20 minutes orso. Always use lint-free cleaning cloths.

n Stir the can occasionally during the work.

n Dampen the ground with water beforecommencing painting to avoid any dust rising.

n Use a worn brush for the final coat, this willensure less brush marks.

n Painting is best achieved on warm, drymornings – cold weather retards drying anddamp will spoil the gloss.

n Never apply direct from the can as this willintroduce contamination.

n Always pour the amountof paint that you expectto use into a separatecontainer.

Bare substrate:

Check for areas ofdamage, separation or peeling, or any otherindications that theexisting coating is notfirmly adhered to thesubstrate.


See Pages 42-43 for undercoatrecommendations.

See Page 21 for advice on removing existing finishes.

For health and safety reasons, two-partpolyurethane products should only be spray applied by a professional applicator.

Due to the porous nature of aged gelcoats, the risk of moisture or solvent entrapment – leading to blisters – is increased; applying Interprotectfollowed by Epoxy Primekote can reduce this riskand seal the gelcoat, prior to applying the finish.

Mixing the second coat of undercoat 50:50 withthe topcoat will produce a satin effect, which willhighlight any imperfections (to be sanded smooth)as well as improving the gloss and depth of colourof the finish.

Health and Safety

Before commencing preparatory work, ensure the area you are working in is adequately ventilated. Ensure you are wearing the correct PPE; we recommend safety spectacles, goggles or visors, nitrile rubber gloves, overalls (ensuring skin is not exposed) and a solvent mask. Please consult Page 16.

We recommend that the first coat of varnish appliedis thinned up to 15%-20%. This will promote goodpenetration of the surface, and adhesion ofsubsequent coats. After the first coat has beenapplied, the surface will appear rough. This is aresult of the exposed ends of grain absorbing thevarnish and lifting. Sand smooth with a 220 gritsandpaper and apply a second coat thinned10%-15%.

Apply 2-3 thinned coats of varnish following labelrecommendations.

Alternatively, prime using Clear Wood Sealer FastDry; a clear polyurethane primer with excellentgrain filling properties that will improve overallscheme durability and aesthetics.

Stan SusmanTechnical Sales Representative

Applying varnishesTo achieve a professional result from any varnish project, thorough preparation iscritical. If applying on to a previously varnished surface, the condition of the existingcoating and its compatibility with the new varnish product should be thoroughlychecked before commencing any preparatory or application work.


See Page 21 for advice on removing existing varnishes.

See Page 17 for substrate preparationguidelines.

It is important to ensure all sanding residue isremoved prior to varnishing, as this will impairadhesion and give a ‘bitty’ finish. Beforecommencing any varnish work, decant the amount of varnish you expect to use into aseparate container, to avoid introducingcontamination into the tin.

Applying varnish with a brush is usually the bestmethod, although roller application can be effectiveon large, flat surfaces.

Brush out, using firm strokes along and then acrossthe grain, holding the brush at 90º to the surface.

Finally, ‘tip off’ by gently stroking surface with thebrush at a 45º angle, following the grain. The brushyou use should be used only for varnishing.

Always follow the scheme recommendations as specified on the label; this will indicate theminimum number of coats required and thesanding recommendations between coats. Thisinformation will vary depending on the product.To achieve long-lasting protection, you shouldplan to apply up to ten coats (depending on thesystem). As the number of coats increases,sanding between coats with a fine grade paperwill increase the level of gloss and depthof lustre.

Applying antifoulingAntifouling can be applied using a brush or roller. Using a small roller is less workon the arm but takes longer to cover the surface area. If a brush is preferred,choose a large width brush; the finish will not be as smooth as a topside paint so the type of brush used is not critical.

Health and Safety

Before commencing preparatory work, ensure the area you are working in is adequately ventilated. Ensure you are wearing the correct PPE; we recommend safety spectacles, goggles or visors, nitrile rubber gloves, overalls (ensuring skin is not exposed) and a solvent mask. Please consult .

Seal incompatible or unknown antifoulings with Primocon. Bare substrates should be primed,according to substrate. Product recommendationsare provided on labels and data sheets. Rememberto pay particular attention to drying times andovercoating intervals.

Repair/Priming5

Mix paint thoroughly with a stirring stick, ensuringthat any settlement is mixed in. Apply according tolabel recommendations, using a brush or roller.

Application6

In poor condition

Completely remove all antifouling paint withInterlux® Interstrip 299E for fiberglass or woodand by sandblasting steel surfaces to anear white metal.

See Page 22 for advice on removing existing antifoulings.

See Page 47 for advice on osmosis treatment.See Page 20 for advice on repairing fiberglass.

Before priming orapplying antifouling,mask off the area to bepainted.

Masking4

Apply the antifouling atthe correct thickness;this may mean anextra coat is needed,depending onapplication methodsand conditions.

Apply an extra coat to leading and trailing edges;e.g. waterline, trim tabs, outdrives, keels andrudders. These areas experience more waterturbulence and so more wear on the paint surface.

Follow overcoating times and immersion times carefully. Failure to do this could result in detachment, blistering or cracking of theantifouling. The marine environment is harsh for paint so it must be allowed to dry thoroughlybefore immersion.

1. Check for compatibility with old antifouling.If you know what antifouling is currently on yourboat, you can quickly determine whether yourInterlux paint choice is compatible.

2. Use Primocon YPA984 as a tie-coat primer.If you do not know what the old antifouling is onyour boat, thoroughly sand with 80 grit sandpaper,wipe clean, and then prime with Primocon YPA984primer. Then, simply overcoat with the Interluxantifouling of your choice. (Not compatible withVC® Offshore, Baltoplate, VC®17m, orVC®17m Extra.)

Applying your desired Interlux® antifouling has never been easier. Compatibility is always an issue boaters must worryabout, but there are 3 easy steps to solve this problem:

3. Remove old antifouling. If you would prefer to remove the old antifouling, we have the easysolution, Interlux Interstrip 299E paint remover. It’s compatible with your valuable fiberglass hull.Interstrip can remove several coats of paint in oneapplication. After stripping, you are ready to primeand paint your newly cleaned hull.

How much antifouling paint do I need?Determining how much antifouling you will need is fairly simple. Here are two quick guides to help youpurchase the correct amount:

1. Calculate the area needing paint. For a rough estimate of the area to be painted, multiply the length of your hull(LOA) by the beam and multiply by 0.85 (LOA x B x 0.85 = Area). Then divide the area by the coverage of thepaint you’ve chosen to determine how many quarts per coat you will need, or

2. Refer to the reference chart below for a quick estimate of how much antifouling paint is required for two coats:

Important: Now that you’ve stripped yourhull, it is important to inspect for any gelcoatdamage before repainting. Also, consider applyingthe InterProtect® System to give your hull a barriercoat to protect from gelcoat blistering.

Top Tips

n Apply an extra coat to all leading and trailing edges,water-line, trim-tabs, outdrives, keel and rudder. High turbulence in these areas tends to wear theantifouling faster.

n Always use the specified amount of antifouling. Under-application can result in premature fouling and costly mid-season haul out.

How to protect against osmosis Osmosis protection schemesFiberglass: InterProtect® 2000E

Proper preparation of the gelcoatThis includes getting all of the antifouling

paint and primers off and removal of as muchgelcoat as necessary to get the hull dry (i.e. theentire gelcoat or just small areas). A professional,who has looked at your boat, should make thisdetermination.

Drying of the hullThis is the most critical step in the process.

If you do not get the hull dry it will re-blister. We recommend a comprehensive washing anddrying procedure.

Application of Epiglass®

Epiglass is a solventless epoxy used to sealup the laminate and fill any cloth that has beenvoided of resin.

Application of InterProtect® 2000EInterProtect 2000E provides a water barrier to

minimize the possibility of reoccurrence of damageand will act as a tie-coat to the antifouling. Contactour Technical Help Desk to obtain a copy of theInterProtect Bulletin 900.

Before commencing preparatory work, ensure thearea you are working in is adequately ventilated.Ensure you are wearing the correct PPE; werecommend safety spectacles, goggles or visors,nitrile rubber gloves, overalls (ensuring skin is notexposed) and a solvent mask.

Health and Safety1

If more extensive damage is found or suspected we recommend that you seek the advice of aprofessional surveyor before continuing.

Inspect the gelcoat for signs of damage or cracking.Small defects can be repaired with Watertite EpoxyFiller following the instructions on the product label.

Inspection3

Remove all contamination from the surface usingFiberglass Solvent Wash 202 or Fiberglass SurfacePrep YMA601V. Sand using 80-grit sandpaper.Remove the sanding residue using FiberglassSolvent Wash 202.

Preparation2

If your hull is new, proceed to Step 4.

Apply InterProtect 2000E, building up to minimumdry film thickness of 10 mils (this will typically take5 coats) using a brush or roller. For ease, alternatebetween the gray and white shades.

Application4

Look out for any warning signs that may suggestthat water has entered the laminate or thatosmosis may have occurred.

BlistersBlisters can vary from smallpinhead blisters, to areas aslarge as the palm of a hand.The presence of any fluidbehind a blister indicates a potential problem.

Warning signs

Star crazingThis effect can occur wherethe gelcoat is brittle. Finecracks usually form due to severe flexing or impactdamage, allowing water to seep into the laminate.

PinholesTiny bubblespresent in thegelcoat reduce itseffectiveness andpromote rapidwater absorption.
