With over 30 years of successful use, Duratec Hi- Gloss Additive is the proven
leader for post-application gel coat work. Hi-Gloss Additive converts gel coat to
air-cure chemistry, leading to a smooth, porcelain-hard surface. Use this product
in applications such as complete gel coat resurfacing, plug and pattern
manufacturing, and gel coat repair. Blend with the original gel coat to match to
desired color. Make gel coat repair come out perfectly every time!
FEATURES
NO DULL SURFACE
Additive eliminates the need for
wax & PVA creating a superior
finish.
ELIMINATES LOW-GLOSS
Especially areas on the edges of
repairs, like the low-gloss donut
often seen in gel coat repairs.
BETTER PROFILE
Flat & smooth profile compared to
un-modified gel coat or gel coat
with wax & styrene.
REDUCED POROSITY
In tooling gelcoat. Improves air
release, thus preventing porosity.
FASTE R & EASIER REPAIR
The air-cure blend created with
gelcoat cures fast and hard,
creating a shiny smooth surface
that is easy to sand.

FETY & HANDLING
Duratec
Hi-Gloss Additive is extremely flammable. Do not apply near sparks,
open
flames or heat. Keep area ventilated. Do not smoke. Avoid continuous
breathi
ng of vapor. Duratec Hi-Gloss Additive contains ingredients which could be
harmful
if mishandled. Contact with skin and
eyes should be avoided and
necessary protective equipment and clothing should be worn. Individuals should
wash
with soap and water before eating or drinking. All containers should be
properl

APPLICATION GUIDE | PRODUCT #904-001
Catalyze with full strength MEKP catalyst at 2%, like Norox 925 (about 20 mill
iliters per quart).
Spray 3-4 passes over the repair, building up 12-15 mils. Allow at least two minutes between
passes. Do not allow the Duratec/gelcoat to cure beyond the sticky/thumbprint stage between
coats… usually about 30 minutes at 77 F when sprayed, faster in the cup. Feather the edge of
the repaired area.
Prepare
Temperature should be at least 64 F. Low temperatures extend cure time.
A test blend is recommended
, as every blend is unique and the cure must be tested and assured.
The cure time of the blend will vary, as every gelcoat is di erent. Note the cup-gel time.
If repairing, remove or
fx any cracked or damaged gelcoat. Grind out cracks down to the laminate.
Repair laminate or assure the laminate is sound. We recommend Duratec Vinyl Ester Mold Repair Putty
(1800 Series) for laminate repair.
Sand with 180 grit to a few inches outside the repair area. Bevel the edge of the existing gelcoat.
Blend
OPTION #1: 1 part (25%) Duratec 904-001, 3 parts (75%) gelcoat.
Recommended to maximize the hide (opacity). If opacity is not an issue, use option #2.
The following use instructions are broad to address multiple applications. We recommend testing for product
compatability with your process. Please contact our Tech Team at (909) 546-1160 with any questions.

Catalyze with full strength MEKP catalyst at 2%, like Norox 925 (about 20 milliliters
per quart).
Spray at least 2 passes over the repair, building up an additional 8 mils or more to match
surface. Be sure to get back onto the first passes while they are sticky.
Cover all the
previously coated area.
Feather the edge of the repaired area.
NOTE: if you are not doing a repair area, and instead covering
an entire surface, build up 18+
mils overall, 5-7 mils at a time while
allowing out-gassing to occur between passes.
Once surface cure is sandable (approx. 2-4 hours) sand as outlined below to cut surface and allow full
cure.

OPTION #2: 1 part (50%) Duratec 904-001, 1 part (50%) gelcoat.
Recommended for all repairs where opacitiy is not an issue. Not recommended for dark colors.

Once surface cure is sandable (approx. 2-4 hours) sand as outlined below to cut surface and allow
full cure.
Sand
Sand
when the surface has cured enough to not clog your paper. Start with the finest grit that is
reasonable for the surface finish. With a good finish starting with 400 grit is possible.
The surface must be open for at least 8 hours between initial sanding and polishing. The open time
allows for styrene release and full cure.
Sand with progressively finer grits like 400, 600, 800, 1000. Compound and polish with products
formu-lated for gelcoat like Aqua Buff 1000 and Aqua Buff 2000.
Cure Times
Duratec High Gloss Additive is an air-cure product. Each gelcoat manufacturer and color option will
have a different cure time. Those cure times, combined with factors like ambient temperature,
humidity, catalyst ratio, and mil depth can result in a spectrum of cure times. Some surfaces will be
ready within two hours, others may take more than 24-hours for full cure. Avoid spraying in
temperatures below 64 F, and where possible, increase heat near part to improve cure time.

TROUBLESHOOTING | PRODUCT #904-001
Problem Cause Solution
Possible incompatibility between
additive and gelcoat.
Check both products separately for cure;
if ok, the products are not compatible.
High humidity.
Apply heat or spray in controlled humidity environment.1:1 Blend with gelcoat
fails to cure
Cool temperatures.
Fisheyes
Spray in controlled temperature environment.
Possible incompatability between additive and gelcoat.
Air contaminiation. (The lower viscosity of the additive/gel coat blend increases the susceptibility to fsheyes).
Check water and oil fltration in the air line.
Check both products separately for cure; if ok, the proucts are not compatible.
Improper catalyst used.
Ensure using full strength catalyst at the recommended 2% ratio.
