• Marine spar varnish
• Deep, rich finish
• Build multiple coats quickly
• Excellent UV protection
• High-gloss or matte finishes

TotalBoat Lust is a one-part spar varnish that allows rapid recoating, with no sanding between coats. It cures to a deep, high-gloss or matte amber finish with maximum UV protection. Lust Matte is recommended as a finish coat over build coats of Lust High Gloss spar varnish, for a beautiful, low-sheen finish. Our unique formula allows overcoating in 1 hour at 72°F, up to 5 coats in one day. Its durability and strong UV protection make it a great choice for interior or exterior brightwork.

Acceptable Substrates

Wood, previously varnished wood in good condition, properly prepared epoxy, or previously painted surfaces

Surface Preparation

Bare Wood

• Wood should be in good condition, dry, and free of any grease, oils, tar, dust, wax, or other potential contaminants prior to sanding.
• The ideal wood moisture content to varnish is 6-8%, but being less than 10% usually yields good results. Varnishing wood with a higher moisture content is not recommended.
• Sand the wood smooth, in the direction of the grain, with 220-grit sandpaper, until it is even and smooth.
• Vacuum away any sanding dust.
• If desired, a tack cloth can be used to help remove any residual dust, then follow with a clean, lint-free cotton rag wetted with one of the specified cleaner/surface preparation solvents.
• Allow the surface to dry completely before applying Lust varnish.

Previously Varnished Surfaces

• Previously varnished surfaces in poor condition should be stripped back to the bare substrates. Only apply Lust to varnished substrates in good, sound condition that do not show signs of delamination, cracking, or peeling.
• Wash the surface with a mild soap and water, and rinse thoroughly.
• Once dry, wipe the surface with one of the specified cleaner/surface preparation solvents using a clean, lint-free cotton rag.
• Allow any solvents to evaporate.
• Sand the surface in the direction of the grain with 220-grit or 320-grit sandpaper until it is smooth.
• Remove any sanding residue by wiping the surface clean using a clean, lint-free cotton rag wetted with one of the specified cleaner/surface preparation solvents.
• Allow the surface to dry completely before applying Lust varnish.

Teak

• Bare teak wood in good condition has a warm, golden tone. Teak that has been exposed to the elements and that has sat for a while may take on a gray appearance.
• If the teak wood has a gray appearance, it should be cleaned with TotalBoat Teak Cleaner to restore it to its original warm, golden color. Use Part A and Part B, as specified on the instructions, and allow ample time for the wood to dry after. Varnish or other coatings applied to damp wood may blister up or delaminate from the wood if it has not had sufficient time to dry.
• Once the teak wood has been cleaned and thoroughly dried, follow the surface preparation instructions for bare wood.

Epoxy Surfaces

• Epoxy substrates need to be fully cured for at least 5-7 days prior to any surface preparation or applying varnish.
• Once cured, the epoxy must be washed with a mild soap and warm water, then rinsed well to remove any possible amine blush, whether noticeable or not. This must be performed even if the epoxy is considered non-blushing, or does not appear to have an amine blush on the surface.
• Dry the surface completely.
• Sand the surface with 220-grit or 320-grit sandpaper. A DA (dual action) sander can help to reduce a sense of grain, or sanding marks that show a sense of sanding direction.
• Remove any sanding residue by wiping the surface clean with a clean, lint-free cotton rag wetted with one of the specified cleaner/surface preparation solvents.
• Allow the surface to dry completely before applying Lust.

Previously Painted Surfaces

• Only apply Lust on previously painted surfaces that are in good condition, that are compatible with an application of solvent-based varnish.
• Remove any dust, dirt, grease, oils, water, wax, or other possible surface contamination prior to sanding the surface.
• Sand the surface with 220-grit or 320-grit sandpaper. A DA (dual action) sander can help to reduce a sense of grain, or sanding marks that show a sense of sanding direction.
• Remove any sanding residue by wiping the surface clean with a clean, lint-free cotton rag wetted with one of the specified cleaner/surface preparation solvents.
• Allow the surface to dry completely before applying Lust varnish.

Application

VERY IMPORTANT: READ BEFORE VARNISHING!

• Stir or shake Lust varnish very thoroughly before use. This is extremely important to promote the most consistent finish with Lust Matte, as the flattening agent settles over time.
• The minimum overcoat time for Lust varnish is 1 hour @ 72°F, 3 hours @ 60°F, or 6 hours @ 50°F (3 mils wet film thickness).
• Applying Lust varnish thicker than 3 mils wet film thickness will extend dry times dramatically, and could trap solvents, making the varnish squishy and soft, even if the surface has become tack-free.
• Applying the varnish too thin may reduce the gloss level, and require more coats to achieve a desired finish.
• A maximum of 5 coats can be applied per day.
• Sanding is not required between coats if Lust varnish is reapplied within 48 hours.
• Do not attempt to sand Lust unless the most recent coat has dried for a minimum of 24 hours.
• If 2-5 coats have been applied in one day, allow 48 hours drying time prior to sanding.
• Lightly scuff-sand with 320-grit sandpaper, hazing the surface, and reducing any high points or bumps in the varnish. Do not sand heavily, or remove more than is required. Sandpaper that is coarser is not necessary, and will only add deeper scratches that may print through once all varnish layers have cured. Remove any sanding residue before reapplying.
• Do not use any solvent wipes within 48 hours of applying Lust varnish, as it may affect the previous layers, even if it seems hard and cured. A clean, dry cotton rag, or compressed air (with an oil and water separator) is usually sufficient for removing sanding residue. TotalBoat Special Brushing Thinner 100 is the preferred solvent wipe for sanding residue cleanup.
• If a tack rag is used to remove sanding residue, it is imperative to then wipe the surface with a clean, cotton rag dampened with Special Brushing Thinner 100 prior to applying the next coat of varnish.
• A minimum of 6-8 coats of Lust is recommended. The actual number of coats to fill the wood’s grain will vary with each application.
• More coats will produce greater distinctness of image, and greater UV resistance.

High-Gloss vs. Matte Application

• Lust High Gloss varnish should be used for all seal coats and all build coats, regardless of the final desired finish.
• Lust Matte should only be used for the final 1-2 coats of an application, never for a seal coat or build coats.
• Lust Matte yields the best results when a thin, but even coat is applied, reduced 20-40% with TotalBoat Special Brushing Thinner 100 for brushing and rolling applications. Apply it very thinly in the direction of the grain. For spray applications, reduce 30-100% with TotalBoat Spray Thinner 101.
• Lust High Gloss and Matte finishes can be blended to achieve a desired finish.

Application Conditions

• Best results are achieved when the substrate, air, and varnish temperatures are between 60-85°F.
• Do not attempt to apply Lust varnish when the air, substrate, or varnish are below 45°F, or above 105°F.
• If possible, avoid applying or curing the material in direct sunlight.
• Do not apply during times of high humidity, when rain, dew, or fog may affect the drying or finish of Lust.

First Coat on Bare Wood (Seal Coat)

• For the first coat, reduce the varnish, up to 100%, with the appropriate TotalBoat thinner for the application method. This will allow the varnish to penetrate and seal the wood grain.
• Due to the extra solvent and penetration, the first coat may take longer to become tack-free.
• A second seal coat may be applied if desired, depending on how much of the first coat was absorbed into the substrate.
• Hint: To avoid reducing on the first coat, TotalBoat Wood Sealer can also be used on new wood before applying Lust varnish. Simply apply 2-3 coats of Wood Sealer to bare, properly prepared wood. Allow to dry for 24 hours, lightly scuff-sand, and apply Lust, as directed below.

Application Methods

Brushing Instructions

• TotalBoat Special Brushing Thinner 100 promotes the best flow, self-leveling, and working time for Lust varnish, under most application conditions.
• Below 60°F, TotalBoat Spray Thinner 101 can also be used as a brushing thinner for applications in order to help promote a quicker tack-free time, without compromising proper flow or working time.
• TotalBoat Lust is a high-viscosity varnish that requires the addition of thinner to achieve a desired flow and wet edge. This is intentional. It allows the person applying the varnish the ability to control the flow and wet edge based upon the environmental conditions and on their individual varnishing technique.
• For brushing and rolling, 5-10% (or more) brushing thinner is commonly added to achieve desired flow characteristics. For gloss finishes, take extra care to thin Lust as little as possible to promote the highest gloss level possible.
• Do not over-thin Lust beyond what is required for desired flow characteristics, as it will extend dry times, and will reduce the overall gloss level of the cured finish.
• Only use high-quality solvent-safe paint brushes and roller covers with Lust varnish. For best results, use a high-quality natural bristle brush that is designed for varnishes, that is an appropriate width and shape for the application.
• Foam brushes can be used very successfully for seal coats and build, but the preferred method to achieve the best finish is to use a natural bristle brush.
• 1/8" foam or mohair roller covers can be used, but nap or other hair rollers may leave hair or fine particles behind.
• The roll and tip method (applying the varnish across the grain with a roller, and immediately following with a brush in the direction of the wood grain) is also a very successful application method to apply a very even coat across larger areas.

Spraying Instructions

• For most spray applications, reduce Lust 10-25% (or more, as needed) with TotalBoat Spray Thinner 101.
• Always use the minimum amount of spray thinner possible to achieve the highest gloss finish and promote the fastest dry times.
• Actual percentage of reduction will depend on the equipment being used and on the environmental conditions.
• Airless Spray: The pressure should be roughly 170 bar/2500 psi, with a .33-.41 mm (11-16 thousandths) tip size.
• Pressure Pot: The pressure should be 3.44-4.47 bar/50-65 psi (gun pressure), and 8-10 psi (pot pressure), while the tip size should be .89-1.4 mm (35-50 thousandths).
• Siphon Cup: The pressure should be roughly 3.44-4.47 bar/50-65 psi (gun pressure), with a 1.5-1.8 mm (60-70 thousandths) tip size.

Yearly Maintenance

TotalBoat Lust can be cleaned with an all-purpose boat soap, such as TotalBoat Boat Soap, and water. For superior results, applying 1-2 coats annually for exterior applications can maintain the finish and UV protection of Lust varnish.
