ESTIMATING COVERAGE.
1 gallon of mixed epoxy contains
231 cubic inches of volume: One Gallon will cover
approximately 1.6 square feet at 1 inch thick, approximately 6.5
square feet at 1/4 inch thick, and approximately 26 square feet at
1/16" thick. When measuring project for coverage,
include surfaces, edges, and an extra 2% for run off.
SURFACE PREPARATION:
Although it is not possible to
address every type of surface the following is a generic guideline:
Bare wood should be sealed with a
thin coat of epoxy prior to flood coating. Decoupage articles
should be tested for color fastness prior to application. When
recoating an existing epoxy coating, the coating should be scuff
sanded and cleaned with denatured alcohol. Be sure that the
surface and the epoxy to be mixed are at the same temperature.
Preferably 70-75 degrees F. When recoating a previously
painted surface, slight sanding to remove the gloss surface is
required to give the epoxy something to attach to.
(Always wipe down the surface with denatured alcohol prior to
recoating to remove all oils, greases, and other contaminants.
MIXING:
Mixing is the most important part
of the project. Improper mixing will result in soft or tacky
spots in the surface.
First be sure you are preparing to
mix containers of the Hardener and Resin. The black top
typically is the Hardener and the White top is the Resin. (If
you are doing a large project, make sure you have a white cap and a
black cap container. We have seen mistakes where applicators
mixed black caps together, and white caps together. If this
happens, the epoxy will never harden, and it is very difficult to
remove.) Graduated mixing containers are recommended for measuring
and mixing. (Remember this is a 1-1 mix. Adding more
resin or hardener will prevent the epoxy from hardening.) Hand
mixing with a paint stir stick is recommended. It is
also recommended that you mix no more than two gallons at a time.
A two container mix is preferred.
Pour the resin in first and the hardener last. Mix the epoxy
in the first container, stirring very hard for 1-1/2 minutes, and
scraping the sides and bottom of the container to make sure all the
chemicals blend in with each other. Do not worry about the
bubbles, they will come out. After mixing for approximately 1
-1/2 minutes in the first container, pour the entire contents into a
second container, and scrape all the chemicals out of the first
container. Mix the chemicals in the second container for 1-1/2
minutes, scraping the sides and bottom all the time. Mix hard,
just stirring will not do the job.
After mixing the epoxy in the
second container, pour the epoxy on your project. Move the
epoxy around on the project using a notched trowel. The
notched trowel will allow the epoxy to level out and makes it easier
to spread over your project. (Note: DO NOT REUSE MIXING
CONTAINERS. Use them once and throw them away.)
APPLICATION:
Klear Kote is a self leveling
epoxy. Therefore, the surface of the project must be level for
uniformity. The epoxy may be poured on the surface and spread
with a plastic trowel, or a dust free foam brush. (Make sure
the foam brush is a heavy density foam brush.) It is
recommended that you apply no more than 1/8" per coat. Thick
films are achieved through multiple coats.
Once the epoxy is applied to the
desired thickness, tiny air bubbles will appear on the surface.
The bubbles can be removed with a propane torch. Make sure the
torch has an adjustable flame, and set the flame very low.
Pass the flame slowly over the entire project. Do not let the
flame stop and heat up the epoxy, it will cause the finish to
alligator, and bubble up. (DO NOT USE A HEAT GUN, OR HAIR
DRYER). They only blow trash into the surface of the project
and cause air bubbles. You can usually wait about 20 - 25
minutes after pouring to start the degassing process.
CURE TIME:
Cure time will vary with the
temperature and thickness. Whitaker Klear Kote will be tack
free in 1/8" film at 77 degrees F. in approximately 8 hours.
Ready for service in 24 hours.
IMPORTANT NOTE: Even though
the film will appear hard the epoxy will not reach full cure for 14
days. Therefore do not leave objects on the surface until
fully cured. When used for bars or table tops, any hot items
like coffee cups, hot plates, etc, over 140 degrees F. will leave an
impression ring. This happens on most epoxy coatings.
The use of saucers under cups and heat resistant pads under hot
plates are recommended to preserve the finish.
IMPORTANT NOTES ABOUT EPOXY.
Epoxies cure through chemical
reaction. The chemical reaction generates heat, the greater
the mass of the epoxy, the faster the reaction occurs. Pot
life is measured about 4- Oz of epoxy @ 77 degrees F.
Therefore a stated 40 minute pot life is for that 4 ounces. A
- 1.5 gallon mix in a bucket will have only have a 10-15 minute pot
life.
Epoxies will amber slightly when
exposed to sunlight, or UV rays. Exterior applications will
amber and chalk.
For exterior applications, a top
coat with polyurethane with a UV inhibitor is recommended.
Blemishes caused by contaminants
or insects can be sanded and recoated without ruing clarity.
CLEAN UP:
Use Denatured Alcohol, or Acetone
to clean up. Make sure you wear gloves to protect your hands.
It may be necessary to wear a mask
when using Acetone.
IF THIS IS YOUR FIRST EXPERIENCE
WITH EPOXY COATINGS, EXPERIMENT ON A SIMILAR SURFACE. THIS
WILL KEEP YOU FROM MAKING A BIG MISTAKE.
