TotalBoat White and Neutral Gelcoats

Isophthalic White and Neutral Gelcoats create a durable, shiny finish, and are available with & without wax additive.

Gelcoat with wax makes the final gelcoat layer cure to a hard sandable finish, with no wax paper or special tools needed.

Gelcoat without wax additive is ideal if you're laying up a mold for a new boat or a fiberglass part where you're laying down the gelcoat first, then applying more layers of resin and fiberglass on top. In this case, you don't want the gelcoat to cure completely.

Neutral gelcoat is better with coloring agents. White is more opaque with coloring agents.

MEKP is included as the catalyst. To thin, use styrene (sold separately).

Available in Quart and Gallon Kits. Wax additive also available for use with gelcoat without wax.

The gelcoat you are buying is an Isophthalic NPG gelcoat with or without wax additive.

The gelcoat without wax is used for layups when you want the initial layer of gelcoat to remain tacky to the touch while you're laying reinforcement plies on top in order to create a strong chemical bond in the laminate. If you use unwaxed gelcoat as the finish coating, you must spray PVA (polyvinyl alcohol) over it or use wax paper or some other means to effect a proper cure.

The gelcoat with wax is used for an air dry post-applied application. The wax additive rises to the surface, making a film that creates an air barrier, allowing the final gelcoat layer to cure properly.

IMPORTANT - Do not Apply Gelcoat Directly on TotalFair:

Gelcoat should not be applied directly over TotalBoat TotalFair epoxy fairing compound or the gelcoat will not cure properly. Instead, apply TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect Epoxy Barrier Coat Primer over TotalFair, before applying Gelcoat. Primers are sold separately.

MIXING DIRECTIONSs: NOTE: The higher the percentage of catalyst, the faster the gelcoat will dry. Air and surface temperature will also affect the drying of the gelcoat. The colder the air temperature, the higher the percentage of catalyst you should use.

TotalBoat Gelcoat requires MEKP (methyl ethyl ketone peroxide) catalyst to cure. As with all polyester resin, rate and degree of cure are a function of catalyst concentration and of temperature. Resin and work area should be between 70°F and 95°F to ensure satisfactory results.

At 77°F, TotalBoat Gelcoat requires the addition of 2% MEKP catalyst, by volume: 14-16 drops per ounce, or 2 teaspoons per pint, for a working time of 10-15 minutes. The amount of catalyst may be adjusted in small, incremental amounts, either upward or downward, to account for temperature differences (more for cooler temperatures, and less for warmer temperatures). The acceptable amount of MEKP is 1-3%. Do not use more or less catalyst than this or you may get an improper cure, with laminates exhibiting moderate to severe post cure after demolding. Once cured, the gelcoat can be dewaxed, wet sanded, and buffed.

If using a wooden mixing stick, place the stick in the resin before adding catalyst so the wood doesn't absorb the catalyst.

Directions for Wax Additive (sold separately)

Wax additive is a mixture of paraffin and styrene. When adding it to gelcoat, you must also add the MEKP catalyst. Wax additive is added to the gelcoat on the final layer of a wet layup to create a tack-free surface that sands easily before applying the finish coating. Wax additive is not needed when additional layers or gelcoat are applied on top. Add 4 oz. of Surface Seal Wax Additive per gallon (20 drops per ounce) of TotalBoat Gelcoat Without Wax. Note that in temperatures below 70°F, the paraffin can solidify in the container. Place the container in the sun or in front of a lamp to liquefy. USE CAUTION - WAX ADDITIVE IS FLAMMABLE!

Wax additive is available in a 4 oz. bottle. Refer to the table below for how much wax additive to add to gelcoat without wax. Too much wax additive will result in fish eye and other undesirable results.

Amount of Gelcoat w/o Wax  Wax Additive Required 
1 ounce  20 drops 
1 pint (16 oz.)  1/4 ounce 
1 quart (32 oz.)  1/2 ounce to 1 ounce 
1 gallon  4 ounces

Happy with this Gelcoat


This is a nice bright white gelcoat. I have applied it with brush, roller, and preval Disposable spray when repairing various cracks, holes and breaks in our youth sailing fleet of boats- happy with the gelcoat!I'm not a pro - here's a pic of a C420 bow that rammed the dock head-on one too many times... glassed with JD Polyester laminating resin and topped using JD Gelcoat right out of the can -without and coloring agents... please judge the gelcoat ...not my repair job :)

Easy to work with.


The finish is rock hard. I only mixed up 20 ounces at a time. I used the 3M Accuspray gun with a 2.0 nozzle thinned with Styrene 10%

Good product. Not as intimidating as you would think.


I used the total boat poly laminating resin and glassed in a block to mount an anchor winch. Poly resin does not cure by itself. I used the gel coat with wax as a final layer. Keeping in mind I live in Tulsa Ok and it is summer here. That said I used a bit less mekp than it called for (about 3 drops less per oz). I put down two coats lightly sanding between and had absolutely no issues. I also used the liquid tint and was able to color match and fade with no problems using a foam hotdog roller. This was my first time working with fiberglass and gel coat. Seeing as it's pretty easy to work with. I'll do the interior of the boat next. My suggestion. Read the instructions. It clearly states X amount of drops per oz at X temp. Adjust accordingly and make sure the surface is correctly prepped.
